Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the technical solutions of the present application, but not all embodiments. All other embodiments, based on the embodiments described in the present document, which can be obtained by a person skilled in the art without any creative effort, are within the scope of protection of the technical solutions of the present application.

Some of the concepts involved in the embodiments of the present application are described below.

1. Decentralizing: is a phenomenon or structure that must occur or exist in a system having numerous nodes or in a group having numerous individuals. The effects from node to node can form nonlinear causal relationships through the network. This open, flattened, equal systematic phenomenon or structure, we call decentralization.

2. Blockchain (Blockchain): essentially a de-centralized database, is a string of data blocks that are generated in association using cryptographic methods. Each data block stores information required by service, and meanwhile, contains block header information for verifying the validity (anti-counterfeiting) of the information, establishing connection and generating a next block. Blockchains possess the advantages of decentralized robustness, bayer-based security, self-verification and operational independence of all nodes, etc.

3. Duplex accounting: is a relatively scientific billing method requiring that each economic service occurring be recorded in two or more accounts for equal amounts, which completely reflects the full view of the manufacturer's economic service. The types of the duplex accounting method include a lending accounting method, a receipt and payment accounting method, an increase and decrease accounting method, and the like.

4. Lending billing: is a common method in duplex accounting, and is mainly characterized in that:

(1) each account is debited and credited by taking the debits and the credits as billing symbols. Specifically, an increase in assets and fees debits, a decrease in assets and fees debits, and the balance is reflected in the debit; the increase in liabilities, owners interests and revenues debits, the decrease in liabilities, owners interests and revenues debits, the balance being reflected in the lender.

(2) Taking the 'have to have credit and the credit must be equal' as the billing rules, each economic service is billed into two (or more) accounts, and each account is billed with equal amount.

(3) And (3) taking the sum of the occupied funds equal to the sum of the sources of funds as a balance formula, and checking the correctness of the account book record by utilizing the relationship that the sum of the borrower balances of all the accounts is necessarily equal to the sum of the credit balances of all the accounts.

5. And (3) account returning: in the embodiment of the application, the idea of block chain duplex accounting is utilized to take each recoverable package produced by a producer as a loan, and the account returned after each recoverable package is recovered by a recovery center can be understood as the loan returned when the producer produces the recoverable package.

6. The recyclable packages are packages which can be recycled to be raw materials for production or can be recycled after being processed, and the general packages are various packaging containers which are used for packaging products or commodities of enterprises in the production and circulation processes and sold, borrowed or rented to a purchasing party along with the products or commodities, in particular to packages which can be recycled integrally, such as bottles, cans or boxes. Wherein: the material of the recyclable package comprises glass, plastic, paper, metal, and a cola package, and the recyclable package can be in the shape of a bottle, a box, a bag, a box, a pop-top can, and the like. The Lile package is a composite paper package produced by a full sterile production line of Swedish Lile company. Is a large supplier providing a complete packaging system for liquid foods (e.g., milk, juice).

The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are for illustration and explanation only, and not for limitation of the present application, and embodiments of the present application and features of the embodiments may be combined with each other without conflict.

Fig. 1 is a schematic diagram of a current plastic bottle recycling method according to an embodiment of the present application, which specifically includes:

the manufacturers produce plastic bottles, and because the manufacturers need to pay deposit to the service side, the production cost is increased, and the price of the consumers when buying the plastic bottles is also increased. Only after the consumer delivers the plastic bottle to the recycling machine, the consumer can obtain deposit return, and the part with the increased price is returned to the consumer.

The above method relies on a single service provider, and there are multiple benefits exchanged in the flow, thus bringing the following problems:

1. if the service side does not deploy the recycling machine to a part of areas in the process, the cost of the consumers in the part of areas is totally attributed to the service side, and the unfair benefit influence is generated on the combination process;

2. the concrete situation that which plastic bottle is recovered in the place is not recorded, how to calculate deposit and whether cheating and money brushing exist is difficult to be reflected;

3. the above approach relies on a single point service, which is a black box for the consumer as a whole.

To sum up, in the prior art, manufacturers have no long-term tracking means for the use and production of pollutants, and the middle may generate a Mongolian situation. For recycling of recyclable packages, there has long been a lack of a stable, transparent statistical solution, and the whole waste recycling industry requires a new technical support to meet the quantitative analysis requirements.

In view of this, the present application proposes a method for effectively recycling the recyclable packages, regarding the production of the recyclable packages as a lending, each recyclable package needs to have a unique code, and after being produced, a lending record corresponding to the recyclable packages is generated in the blockchain, and the lending needs to be returned according to the logic of the complex ledger. When the recyclable package is recycled, blockchain checkout is performed according to the unique code of the recyclable package, which is mainly described below in terms of a key. The full-network compound account book is realized through the block chain, the data condition from production to recovery of each recoverable package is recorded, the accurate and reliable metering of the recovery of the recoverable package is realized, and the progress of the garbage disposal industry based on data is promoted.

Fig. 2 is a schematic view of an application scenario of an embodiment of the present application, where a blockchain system for recycling recyclable packages is provided, including: the production node 10, the blockchain node 20 and the recycling node 30, wherein when the production node 10 needs to produce the recyclable wrapper, the production node determines transaction information according to a producer, a statistical interval, a recycling type and the like of the recyclable wrapper produced as required, attaches a key obtained by encoding the transaction information to the recyclable wrapper, and sends the determined transaction information to the blockchain node 20 through a billing request, and the blockchain node 20 records a transaction of the recyclable wrapper corresponding to the transaction information in the billing request in the blockchain after receiving the billing request. When a produced recyclable package is detected by the recycling node 30, the recyclable package is recycled, the recycling node 30 obtains transaction information of the recyclable package by acquiring a secret key on the recyclable package and decoding the secret key, after the recycling node determines that the recycling condition is met, the account book information determined according to the transaction information of the recyclable package recycled after the last time the recycling condition is met is sent to the blockchain node 20 through a recycling request, and after receiving the recycling request, the blockchain node 20 performs recycling on the blockchain according to the account book information in the recycling request.

One of the production nodes may correspond to one of the manufacturers, which refers to the enterprise, individual business, etc. responsible for producing the recyclable packages. Taking an enterprise as an example, all enterprises share a blockchain, and the more manufacturers on the blockchain, the higher the public confidence. The block chain does not belong to any enterprise, and is commonly maintained for people.

In the embodiment of the application, when the production node needs to produce the recyclable packaging material, the production node determines the transaction information of the recyclable packaging material to be produced and sends the transaction information to the blockchain node through the accounting request, and the blockchain node performs accounting according to the transaction information in the accounting request.

It should be noted that, in the embodiment of the present application, the blockchain system includes at least one blockchain node, each blockchain node stores one identical blockchain, where the transaction information recorded in the blockchain is recorded on a transaction ledger, and the transaction ledger is equivalent to an account, and is a shared ledger for providing operation functions of storing, querying, modifying, etc. the transaction information is recorded in countless blocks by being scattered, and is connected in series to form a distributed storage. The method solves the credibility problem of a large-scale numerical statistics system by utilizing the characteristic of the block chain, and solves the statistics problem of macroscopic garbage collection in actual life by utilizing the characteristic.

Referring to fig. 3, an optional Block Structure (Block Structure) provided in an embodiment of the present application is shown, where a Block chain includes a series of blocks (blocks) that are connected to each other according to a generated chronological order, and each Block includes a hash value of a storage transaction record of the Block (hash value of the Block) and a hash value of a previous Block, and each Block is connected by the hash value to form the Block chain. In addition, the block may include information such as a time stamp at the time of block generation. The new block is not removed once added into the blockchain, and the recorded data submitted by the nodes in the blockchain system are recorded in the block, wherein the recorded data refer to the transaction information of the recoverable package submitted by the production nodes in the blockchain system.

Taking plastic bottles as an example, the plastic bottles produced in China currently have hundreds of millions each year, and considering the limit of the number and the size of the blocks and the limit of the distribution deployment capability, the transaction information recorded in the embodiment of the application is relatively simplified, and the statistical quantity of the recoverable packages of the blocks is ensured.

In an alternative embodiment, the transaction information recorded in the block mainly includes: manufacturer information, statistical intervals, and recycling types of recyclable packages, etc.

The production node may send a billing request each time a recyclable package is produced, or may send a billing request each time a batch of recyclable packages is produced.

If the accounting request is sent when a batch of recyclable packages is produced, the transaction information in the accounting request is the manufacturer information, the statistics interval, the recycling type of the batch of recyclable packages, in which case the accounting request also includes the number of batches of recyclable packages produced.

The statistic interval may be determined according to the production time of the recyclable package, and corresponds to a transaction ledger, which represents an interval of the production time of the recyclable package for statistics.

If the statistical interval is 2019, the transaction account book is used for recording transaction information of the recyclable packages produced by the manufacturer in 2019.

When a new manufacturer or a newly produced recyclable package from the manufacturer wishes to add statistics to the blockchain system, it is necessary to provide manufacturer information, statistics intervals, recycling types, etc., and the blockchain node newly adds records of these information on the transaction ledger.

The method comprises the steps that firstly, a manufacturer registers a blockchain through a production node and adds the blockchain into a blockchain system, when the production node needs to produce a certain recyclable package, a billing request is sent to a blockchain node, transaction information of the recyclable bottle is sent to the blockchain node through the billing request, and the blockchain node records the transaction information.

Taking a plastic bottle as an example, when the manufacturer a needs to produce a new plastic bottle with a recycling type of X in the period of 1/3/2019, the transaction information of the plastic bottle can be determined to include: manufacturer a, 2019, type X, manufacturer a sends this information in a billing request through the production node to the blockchain node, which performs billing after receiving the billing request.

In the embodiment of the application, before accounting the transaction information of each recyclable package, the blockchain node needs to carry out audit verification, and records the transaction information of the recyclable package after verification to determine that the recyclable package is actually produced so as to ensure the authenticity of the information in the blockchain.

For example, after the manufacturer produces plastic bottles, the number of bottles is accumulated and recorded on a general ledger of a blockchain, and the transaction information record of each bottle is listed in an audit-related check, so that the bottles are recorded in the related transaction ledger after being actually produced.

When audit verification is carried out, specifically, after the blockchain node receiving the accounting request acquires transaction information in the blockchain node, the transaction information for transaction account book operation is sent to other blockchain nodes in the blockchain system, after the other blockchain nodes verify validity, the transaction information is stored in the temporary block as a response for acknowledging that the transaction information is valid, confirmation can be sent to the blockchain link point initiating operation, and after the blockchain link point initiating operation is confirmed, the temporary blockchain can be sent into the blockchain.

The audit verification listed above is the verification behavior of the blockchain itself, and belongs to the characteristics of the blockchain itself.

In the case that the source data is reported in batches by taking account of the safety problem of the source data as storage service, if someone cheats, a large number of non-existent outputs are reported maliciously, and the last account book can not be aligned, an alternative implementation mode is that a manual audit verification link is added, namely manual production process audit or other safety audit measures, and reported values are combined into audit conditions, so that similar situations can be avoided or reduced.

In an alternative embodiment, if considering the situation of the non-traditional blockchain, the blockchain system releases the blocksize to build a special chain, and the chain only operates in a specified environment, simplifies the hash difficulty, supports the fast-yielding blocks, and can realize supporting the recording of the transaction information of the billion level and the building of the increment blocks. The blockchain system in this case can be more efficient and less labor intensive, and in addition, the blockchain system has a higher capability to support throughput due to the higher performance of the blockchain system in this manner. Therefore, the corresponding production node for reporting the accounting request can be directly deployed on a production machine, and reporting is automatically performed according to production behaviors with unique codes, wherein the unique codes refer to secret keys, and because all reporting behaviors are associated by the unique codes of the output, the optional manual or similar audit links of batch reporting can be skipped.

In the embodiment of the application, the production node needs to send the transaction information to the block chain link point, and also needs to form a key through encoding the transaction information, and attach the key to the recyclable package. And after the recycling node detects that the recyclable package is recycled, decoding the key on the recyclable package to obtain the transaction information of the recyclable package.

Alternatively, the key may be a two-dimensional code or bar code, or other more complex form.

Taking a glass bottle as an example, a key is attached to the glass bottle by spraying a two-dimensional code on the body of the glass bottle, as shown in fig. 4A, the method does not affect popularization and sales of the glass bottle, is easy to identify, can be compatible with various glass bottle structures, and only a few common structures are listed in fig. 4A; fig. 4B is a schematic diagram of key attachment in the form of a bar code, and the key may be attached to the can by spraying or other methods, and the specific attachment position is determined according to the practical situation, so that the key attachment is only an alternative embodiment.

In the embodiment of the application, when the recovery node reports the transaction information of the recovered recoverable package, the recovery node needs to report the transaction information after the recovery condition is met, and the transaction information is sent to the blockchain node by placing the account book information in a recovery request, wherein the account book information is determined according to the transaction information of the recoverable package area recovered after the recovery condition is met last time.

The recycling node may refer to a recycling center, and it is assumed that the recycling node detects a recyclable plastic bottle X1 in month 6 of 2019, and obtains transaction information of the bottle by scanning a key on the bottle by decoding: manufacturer a, 2019, type X.

Optionally, the checkout conditions include, but are not limited to, some or all of the following:

the time interval between the first account returning condition and the adjacent two account returning conditions reaches the preset duration;

the condition indicates that the recycle node periodically initiates a reply request to the blockchain node, the number of recoverable packages detected in different recycle periods is not fixed, and no recoverable packages are detected in one period, and the method is as follows:

taking three months as an example of the preset time length, the recovery period is three months, and if no recoverable package is detected within three months, the request for account recovery can be sent to the block chain link point no longer; if 1 ten thousand recoverable packages are detected within three months, account book information is determined according to the transaction information of the 1 ten thousand recoverable packages, and the account book information is sent to the blockchain node through an account returning request.

In an alternative embodiment, the preset time period may be adjusted iteratively, in particular by collecting real-life recoverable package yield data and garbage recovery data.

Taking plastic recycling as an example, the amount of plastic bottles in statistics of 3 months of one preset time according to the currently disclosed data can not exceed 100 hundred million, so that the plastic bottles can be gradually adjusted from 3 months, the relative controllability is little, the amount is too large if the relative controllability is too long, and the recycling effect is not obvious if the relative controllability is too short. In particular, data feedback is needed with reference to the advice and implementation phases of the relevant production, environmental protection domain specialists.

In addition, the design of the cycle requires some data to assist in the correction, generally ensuring that the statistical interval is not less than the life cycle length of most returnable packages.

The design based on the recovery period in the above embodiment has the following advantages:

the recoverable packages between time points A-B are placed on the same transaction ledger, i.e. the transaction information of recoverable packages with the same recovery period is recorded on the same transaction ledger. Therefore, no matter when the recyclable package reaches the recycling node, the corresponding transaction account book can be found for account returning, and production and recycling conditions in other time periods cannot be affected by errors.

And the quantity of the recoverable packages recovered in the time period between two adjacent account returning conditions reaches a preset threshold value.

The condition indicates that the time for the recovery node to initiate the account returning request to the blockchain node is not fixed, but when the request is initiated each time, the quantity of the detected recoverable packages between two adjacent requests is consistent, according to the account returning condition, the recovery node can send the account returning request to the blockchain link point after recovering one recoverable package, and can also report the aggregate series transaction after recovering a plurality of recoverable packages.

Specifically, when the preset threshold in the second accounting condition is 1, the machine sends an accounting returning request to the block link point every time when one recoverable package is recovered, for example, after detecting the recoverable plastic bottle X1 listed in the above embodiment, the recovery node sends an accounting returning request to the block link point, automatically reports the transaction, and the block link node performs accounting returning processing to return the transaction record recorded in the block about the recoverable plastic bottle X1.

In this way, the account information in the account returning request is the transaction information of the recyclable package detected this time, and, for example, the recyclable plastic bottle X1, and the account information in the account returning request is the transaction information of X1.

Assuming that after one day the recycling node detects another recyclable plastic bottle X2 again, the transaction information obtained by decoding the key on the bottle is: manufacturer a, 2019, 3 months production, X type, thus re-initiate a request to the blockchain node to return account, and the account information in the request is the transaction information of X2.

When the preset threshold value in the account returning condition II is greater than 1, the recovery node is indicated to need to recover a plurality of recoverable packages and send an account returning request to the block chain link point, for example, the preset threshold value is 3, the three recoverable packages are reported to the block chain node once every time, if the recovery node detects three recoverable plastic bottles in sequence, namely X3, X4 and X5 respectively, the account returning request is reported to the block chain node when X5 is detected, and account book information in the account returning request is determined according to transaction information of X3, X4 and X5; after one day, the recycling node detects three recyclable plastic bottles, namely X6, X7 and X8, and can report a return account request to the blockchain node again, and account information in the return account request is determined according to transaction information of X6, X7 and X8.

If the transaction accounts to which X3, X4, and X5 belong are different, there may be a case where a plurality of accounts are modified at a time in this way, and the reporting efficiency is higher in this case than in each case.

It should be noted that, in the embodiment of the present application, the design of the account returning request has no special requirement for the specific time of the recovery node when the account returning request is requested, and the account returning request does not need to be initiated in a fixed period, so that the account returning can be initiated at any time as long as the recovery is generated. It is also possible that the earlier the reclamation node is willing to send out the data the safer. Thus, when an alternative return mode is exemplified, it is recommended to preferentially exemplify a safer at-time reporting mode, and such a fixed-period reporting mode is recommended as an alternative.

In the embodiment of the application, the recycling node should also place the transaction value in the account returning request and send the transaction value to the blockchain node, wherein the transaction value corresponds to the transaction account book and is used for indicating the quantity of the recyclable packages needing to be returned in the corresponding transaction account book in the current account returning process, and the transaction value, the manufacturer, the statistical interval and the recycling type.

Specifically, the recovery node determines a transaction ledger which needs to be subjected to account recovery in the blockchain according to the transaction information of the recoverable package recovered after the last account recovery condition is met; for any transaction account book, determining a transaction value corresponding to the transaction account book according to the quantity of recoverable packages needing to be subjected to account returning in the transaction account book.

Assuming that the recycling period is 3 months, 100 glass bottles are recycled in statistics of 4-6 months in 2019, wherein 30 glass bottles belong to enterprise A for production, 20 glass bottles belong to enterprise B for production, 50 glass bottles belong to enterprise C for production, the production time is 2019, the recycling types are A types, the transaction value corresponding to a transaction account book for recording glass bottle transaction information produced in 2019 by enterprise A is 30, the transaction value corresponding to a transaction account book for recording glass bottle transaction information produced in 2019 by enterprise B is 20, the transaction value corresponding to a transaction account book for recording glass bottle transaction information produced in 2019 by enterprise C is 50, the 3 transaction values are reported simultaneously when a return account request is sent to a block link point, or one transaction value which can represent the number of the glass bottles is reported, and the like.

In the embodiment of the application, after receiving a return account request generated by a recovery node, the blockchain node acquires account information and a transaction value in the return account request, determines a transaction account corresponding to a recoverable wrapper needing to be returned in the blockchain according to the account information, and returns the transaction account according to the transaction value corresponding to the transaction account in the return account request.

Assuming that the transaction account book for recording the glass bottle transaction information produced by the enterprise A in 2019 is account book A, the corresponding transaction value of the account book A is 30, the quantity of 30 glass bottles is deducted from the account book A during account returning, and the account returning is carried out on the enterprise B and the enterprise C in the same way.

It should be noted that, during blockchain billing, specifically, the account of the recyclable package to be billed is debited to a "central account" by a certain amount, wherein the central account is a general ledger, the account held by the government recycling center, and the account of the recyclable package is a transaction ledger for recording the transaction information of the recyclable package.

When the blockchain carries out account returning, whether the balance of the account where the recovered recoverable package is located is enough or not needs to be confirmed, if so, the account is returned to the central account, namely, the account returned after recovering the recoverable package can be understood as the account of the recoverable package is returned to the recovery center; typically, the number of returns will be less than that of the production, and if not sufficient, an error will be indicated, such as 10 bottles being debited by company a, but 100 bottles being returned to account. For the situation of errors, a account returning and checking link can be designed, if the problems are checked, the account returning and checking link automatically alarms to the service provider, and the service provider intervenes in checking reasons and processing.

Among the possible causes of error are: the enterprise is in production and missing report, or retrieve and judge mistake etc.. Verification of this situation may reflect possible problems in time.

As shown in fig. 5, in order to provide a general ledger record for glass bottles according to an embodiment of the present application, the number of glass bottles produced and recovered by each enterprise to the present example is recorded in a ledger, and fig. 5 is only a schematic diagram of an optional general ledger record, and in the ledger, detailed division may be performed according to the production time, recovery type, and the like of the glass bottles.

In an alternative embodiment, after the use of the transaction ledger currently stored by the blockchain reaches a preset time limit, a new transaction ledger is generated; the new transaction account book is used for recording transaction information of the recyclable packages produced in the statistical interval corresponding to the new transaction account book.

For example, a manufacturer in 2019 has a transaction ledger for recording transaction information of recoverable packages produced by the manufacturer in 2019; by 2020 the manufacturer will have a new transaction ledger for recording transaction information for the recyclable packages produced by the manufacturer in 2020, in a manner that more easily allows statistics to be made for system design goals.

Note that, the yields of different manufacturers are different, and thus, the statistics intervals corresponding to the ledgers may also be different.

In the embodiment of the application, for a small amount of recyclable packages entering the next statistics interval, the statistics interval corresponding to production can be obtained from the secret key during statistics, the recyclable packages can be updated into the data corresponding to the statistics interval, the statistics data and the deduction data can be correspondingly updated, and corresponding data updating, refund and the like can be performed.

For example, when a recovery center receives a glass bottle produced by an enterprise J in 2019 in 2020, the account is leveled off in 2019 when the account is returned, corresponding data can be updated in time after the account is updated, relevant statistics and asset data can be recalculated, and unreasonable period design can be reflected. If tax deduction is performed on the enterprise J in the end of 2019, after the glass bottle is recovered in 2020, the tax deducted by the enterprise J can be paid back according to the transaction information of the glass bottle.

In the embodiment of the application, the recycling of the recyclable packages requires enterprise cooperation to reduce the cost, such as using more environment-friendly materials for propaganda guiding the recycling of users, and the like. The production node can reduce recovery and regeneration costs by means of the strength of the recovery node after registering the blockchain, which in turn reflects the actual performance of the enterprise in helping recovery of the recoverable packages. A good recovery of data is both administrative and enterprise.

Optionally, the block link points generate punishment information according to the accounting result, and send the punishment information to the corresponding production nodes, and the production nodes adjust the production strategy of the recyclable packages according to the received punishment information.

An alternative implementation way is that the real data of garbage disposal can be known according to the account returning result. Based on this data, environmental tax is charged to the relevant contaminated enterprises for maintaining overhead.

One of the referenced tax deduction means is to locate and negotiate an improvement method together with the enterprise based on the recovery data of the enterprise, and require implementation within a certain time. If the enterprise improves on time, punishment is avoided, if the enterprise matching degree is not high, the enterprise is subjected to negotiation from the administrative level, and if necessary, the enterprise is limited to a certain degree. For enterprises actively matched with and built by donation garbage recycling centers, certain subsidies, favorable rewards can be given; the method improves the cost of high pollution manufacturers and highlights the competitive advantage of pollution-free manufacturers.

If the account is returned, the method is equivalent to that no new pollutant is generated, and no new damage is generated as a whole; if the account is not returned, the producer is equivalent to accumulating a lending, and after a period of time is counted, tax deduction is required according to the account record, and environmental maintenance cost is paid by the pollution producer. In contrast, advantages are created in commercial competition for pollution-free manufacturers. Taking the example of fig. 5, enterprise a, enterprise C and enterprise F total 0, indicating that the produced glass bottles have been fully recovered, these several enterprises may be rewarded; business B and business D also have a large portion of the glass bottles not recovered and thus may be given a certain penalty, such as tax deduction.

According to the method, no amount flows before tax collection, enterprises have no profit space, and the more the enterprises produce high-pollution products, the higher the cost in business competition. The more enterprises change into pollution-free products, the less the running overhead of the whole system. If most of the recyclable packages are recycled, a plurality of new orders are not generated, the scale of related industries is not continuously increased, and the progress of garbage disposal process is finally promoted.

It should be noted that, the environmental tax is only a kind of reference reward and punishment information listed in the embodiment of the present application, and the main purpose is to encourage the enterprise to participate actively, provide environmental protection advice for the enterprise, and help to improve the environment.

Referring to fig. 6, a schematic diagram of a product side interface according to an embodiment of the present application is provided, and the schematic diagram is used for recording daily circulation of plastic bottles produced by a company, so that an accurate plastic bottle recycling and inquiring capability can be provided, and by statistics shown in fig. 6, the company can know how much tax expenditure is likely to be caused by the plastic bottles produced currently, so that the current yield can be adjusted according to the statistics result, and early transformation of the company is facilitated. In addition, the enterprise can observe the recovery condition statistics of a period of time before, and the recovery condition of each region reasonably adjusts the marketing strategy, so that the operating cost of the enterprise is saved.

In the embodiment of the application, the purpose of the blockchain system is to perform a data feedback with decentralization, disclosure reliability and high efficiency on the recovered data. Because people cannot forge the secret key and operate the account book, a complete automatic recovery chain is realized. The whole block chain system is transparent to all consumers, and the consumers only need to discard garbage normally.

Because of the metering method for the recovery condition of the recoverable package provided by the embodiment of the application, the production recovery condition of all the recoverable packages is disclosed and transparent, which manufacturers produce a large amount of recoverable packages, and which manufacturers recover a large amount of pollutants, become the data for quantitative assessment in the garbage recovery industry. The data not only can drive manufacturers to carry out industrial transformation, but also influences that more consumers can carry out garbage collection autonomously at the data level. The recyclable packages are considered as lends to manufacturers for production of contaminants, and the manufacturer's metering analysis is performed using a blockchain typical compound ledger model. Meanwhile, the recycling nodes are unified in the garbage recycling center, so that on one hand, garbage recycling work deployment is facilitated, and recycling machines do not need to be arranged fully. On the other hand, the construction of the garbage recycling center is promoted to the manufacturers, and the responsibility of the manufacturers is stimulated. The accurate quantitative analysis of the production recovery data of the recoverable package is realized; the method is beneficial to promoting manufacturers to pay attention to garbage recycling construction and promoting the progress of the whole garbage recycling industry.
