[01] A presente patente de invenção descreve um processo de obtenção de combustível utilizando resíduos sólidos orgânicos provenientes da indústria de processamento de frutas para alimentação de aparelhos/instalações de combustão, obtendo um subproduto útil para processos secundários e que utiliza matéria-prima geralmente descartada no meio ambiente. The present patent describes a process for obtaining fuel using organic solid waste from the fruit processing industry for feeding apparatus / combustion plants, obtaining a by-product useful for secondary processes and using generally discarded raw material in the environment.
ANTECEDENTES DA INVENÇÃO BACKGROUND OF THE INVENTION
[02] O setor da agroindústria gera uma grande quantidade de subprodutos, que em muitos casos são considerados custo operacional para as empresas ou fonte de contaminação ambiental (JÚNIOR et al., 2005 apud SOUSA et al., 201 1). The agroindustry industry generates a large amount of by-products, which in many cases are considered operational cost for the companies or source of environmental contamination (JÚNIOR et al., 2005 apud SOUSA et al., 201 1).
[03] Por exemplo, o processamento de frutas, para a produção de sucos e polpas, gera entre 30 a 40% de resíduos. Como a quantidade de resíduos pode chegar a muitas toneladas, agregar valor a esses produtos é de interesse económico e ambiental, necessitando de investigação científica e tecnológica, que possibilite sua utilização eficiente, económica e segura. (SOUZA, M. S. B.; et al. Caracterização nutricional e compostos antioxidantes em resíduos de polpas de frutas tropicais. Teresina, 201 1.). [03] For example, the processing of fruit, for the production of juices and pulps, generates between 30 to 40% of residues. As the amount of waste can reach many tons, adding value to these products is of economic and environmental interest, requiring scientific and technological research, which enables its efficient, economic and safe use. (SOUZA, M. S. B .; et al., Nutritional characterization and antioxidant compounds in residues of tropical fruit pulps, Teresina, 201 1.).
[04] Os principais resíduos gerados no processamento de polpas de frutas são, dependendo do tipo da fruta processada, casca, caroço ou sementes e bagaço. No entanto, alguns resíduos não apresentam aplicabilidade em alimentos ou o processamento dos resíduos a fim de viabilizá-lo como alimento apresenta alto gasto energético, por
exemplo. Nestas situações, geralmente o resíduo é utilizado como fertilizante orgânico ou na alimentação animal, sem qualquer tratamento. [04] The main residues generated in the processing of fruit pulps are, depending on the type of the processed fruit, bark, stone or seeds and bagasse. However, some residues do not present applicability in food or the processing of the residues in order to make it feasible as food presents high energy expenditure, for example. In these situations, the residue is generally used as an organic fertilizer or feed, without any treatment.
[05] Por exemplo, o bagaço da uva, constituído pela película, as sementes e os restos da polpa da uva, resultado do esmagamento do grão através de um processo de separação do suco ou mosto, representa de 12% a 15% em peso da matéria-prima inicial, e contém restos de açúcar, proteínas e um teor elevado de lipídios. Este bagaço tem se tornado uma alternativa para uso na alimentação de bovinos leiteiro, na forma de silagem ou fresco. No entanto, estudos recentes verificam a transferência de antioxidante polifenólicos para o leite, quando vacas em período de lactação são alimentadas com estes resíduos, e isso resulta na formação de aroma e sabor desagradáveis em produtos lácteos. [05] For example, grape marc, consisting of the film, seeds and residues of grape pulp resulting from the crushing of the grain through a process of separation of the juice or must represents 12% to 15% by weight of the initial raw material, and contains sugar residues, proteins and a high lipid content. This bagasse has become an alternative for use in feeding dairy cattle, in the form of silage or fresh. However, recent studies verify the transfer of polyphenolic antioxidants to milk when lactating cows are fed with these residues, and this results in the formation of unpleasant aroma and taste in dairy products.
[06] Por fim, e não menos raro, o resíduo é descartado no meio ambiente, podendo gerar sérios problemas de poluição no solo, em águas superficiais e em águas subterrâneas. (LAUFENBERG, G.; KUNZ, B.; NYSTROE , . Transformation of vegetable waste into value added products: (A) the upgrading concept; (B) practical implementations. Bioresource Technology, v. 87, n. 2, p. 167-198, 2003.; SCHIEBER, A.; STINTZING, F. C; CARLE, R. By-products of plant food processing as a source of functional compounds - recent developments. Trends in Food Science & Technology, v. 12, n. 1 1 , p. 401 -413, 2001 ). [06] Last but not least, waste is disposed of in the environment and can cause serious pollution problems in soil, surface water and groundwater. (LAUFENBERG, G., KUNZ, B .; NYSTROE, Transformation of vegetable waste into value added products: (A) the upgrading concept, (B) practical implementations, Bioresource Technology, v. 87, n. The present invention relates to a process for the preparation of food-processing plants and a process for the preparation of food-processing plants. 1, 1, pp. 401-413, 2001).
[07] O uso de resíduos da agroindústria está dentro do conceito de química verde, que prevê a redução da poluição nos processos químicos e o aproveitamento máximo da matéria-prima, minimizando ou eliminando a geração de poluentes. Mesmo sendo de fonte natural,
os maiores impactos ambientais provocados por resíduos sólidos orgânicos são decorrentes da fermentação do material, podendo ocasionar a formação de ácidos orgânicos ("chorume" - líquido formado com a degradação do material orgânico e a lixiviação de substâncias tóxicas), com geração de maus odores e diminuição do oxigénio dissolvido em águas superficiais (Graminha, E.B.N.; Gonçalves, A.Z.L; Pirata, R.D.P.B.; Balsalobre, M.A.A; Gomes, E.R.S. Enzyme production by solid-state fermentation: Application to animal nutrition. Animal Feed Science and Technology, v. 144, p. 1-22, 2008). [07] The use of agroindustrial waste is within the concept of green chemistry, which provides for the reduction of pollution in chemical processes and maximum use of the raw material, minimizing or eliminating the generation of pollutants. Even though it is a natural source, the major environmental impacts caused by organic solid waste are due to the fermentation of the material, which may lead to the formation of organic acids ("leachate" - formed liquid with the degradation of organic material and the leaching of toxic substances), generating bad odors and (Wolff et al., 2002), the effect of reducing the dissolved oxygen in surface waters (Graminha, EBN; Gonçalves, AZL; Pirata, RDPB; Balsalobre, MAA; Gomes, ERS Enzyme production by solid-state fermentation: Animal Feed Science and Technology, pp. 1-22, 2008).
[08] O estado da técnica descreve a utilização de resíduos da agroindústria como biomassa para servir de combustível na alimentação de caldeiras. [08] The state of the art describes the use of agroindustrial waste as biomass to serve as fuel in the boiler feed.
[09] O documento FR2499096 descreve um combustível sólido que contém uma ou mais das seguintes características: madeira podada de árvores frutíferas ou vinhas, resíduos de destilaria, espigas de milho, grandes juncos, palha, gramíneas forrageiras e juncos. Após a secagem, se necessário, estes são pulverizados, o melaço ou o bagaço de uva são adicionados como aglutinante e misturados, sendo compactado, servindo como combustível. FR2499096 describes a solid fuel which contains one or more of the following characteristics: pruned wood from fruit trees or vines, distillery waste, corn cobs, large reeds, straw, forage grasses and reeds. After drying, if necessary, these are sprayed, the molasses or grape marc are added as binder and mixed, being compacted, serving as fuel.
[010] O documento CN105368522 descreve briquetes que compreendem de 35-45% de videira, 35-45% de ramo frutífero, 17-20% de esterco de vaca e 1 -2% de um elemento de carbonização e tem densidade maior ou igual a 1300kg / m3 e um poder calorífico superior ou igual a 4800kcal/ kg e uma taxa de briquetagem maior ou igual a 96%. O processo de preparação do combustível sob a forma de briquetes consiste em: esmagamento de videira de uvas secas, ramos de frutíferas e esterco de vacas, pesando as matérias-primas trituradas e o elemento de carbonização de acordo com a relação de massa,
fazendo agitação para misturar uniformemente as substâncias, pulverizando água entre 8 a 12% da massa total das matérias-primas, conduzindo o armazenamento de pilha por 2-4 dias para realizar fermentação simples, de modo a formar resiliência total e, em seguida, a conduzir a moldagem. CN105368522 discloses briquettes comprising 35-45% of vine, 35-45% of fruit tree, 17-20% of cow manure and 1-2% of a carbonization element and has a density greater than or equal to to 1300 kg / m3 and a calorific value of 4800 kcal / kg and a briquetting rate of 96% or more. The process of preparation of the fuel in the form of briquettes consists of: crushing of dried grape grapes, fruit branches and cow manure, weighing the crushed raw materials and the carbonization element according to mass ratio, making stirring to uniformly mix the substances, spraying water between 8 to 12% of the total mass of the raw materials, conducting the cell storage for 2-4 days to perform simple fermentation, in order to form total resilience, and then to lead the molding.
[011] O documento EP1783195 descreve um combustível seco constituído por uma combinação de peles de uvas secas e sementes de uvas secas trituradas, das quais os óleos são liberados e combinados com as peles de uvas secas na forma de peletização. As uvas são esmagadas para liberar o suco, seguido pela separação do suco das peles de uva e sementes de uva. As peles e sementes de uva são primeiro lavadas e depois secas a uma temperatura inferior a 60°C. Antes do esmagamento de peles e sementes, outros resíduos fibrosos secos são incorporados para em seguida serem transformados em pellets. EP1783195 discloses a dry fuel comprising a combination of dried grape skins and crushed dried grape seeds from which the oils are released and combined with the pellets of dried grapes in pelletised form. The grapes are crushed to release the juice, followed by the separation of the juice from the grape skins and grape seeds. The skins and grape seeds are first washed and then dried at a temperature below 60 ° C. Before crushing of skins and seeds, other dry fibrous residues are incorporated and then pelleted.
[012] No entanto, os documentos do estado da técnica descrevem processos e produtos que utilizam o resíduo da agroindústria como uma das cargas, devendo necessariamente ser acrescido de cargas fibrosas e aditivos ou aglutinantes, passando por processos prévios de trituração, lavagem e secagem, o que torna o processo de alto custo e com grande gasto energético, inviabilizando o processamento do resíduo para ser utilizado como combustível. The prior art documents, however, describe processes and products which use agro-industrial waste as one of the fillers, which must necessarily be increased by fibrous fillers and additives or binders, by pre-grinding, washing and drying processes, which makes the process of high cost and with great energy expenditure, making the waste processing unviable to be used as fuel.
