(ロ)有機性廃棄物Aのメタン発酵で排出されるバイオガスG中の二酸化炭素CO2及び消化液Dを用いてカルシウム塊Cを溶解するので、外部からの新たなエネルギーや薬剤等を投入する必要がなく、省資源型・省エネルギー型の処理システムとすることができる。
(ハ)また、バイオマスである有機性廃棄物Aの多段階利用によってカルシウム塊Cを溶解するので、カルシウム塊Cを含む有機性廃棄物Aの全体を小さな環境負荷で処理することができ、地球環境に調和した処理・処分が可能となる。
(ホ)貝類廃棄物の処理に利用できると共に、卵殻、魚や鳥等の脊椎動物の骨や歯、かに殻等の甲殻類の外骨格を含む有機性廃棄物Aの処理に広く適用可能である。
(ヘ)また、二酸化炭素に溶解した有機性廃棄物A中のカルシウム塊Cを環境中に戻すことが可能となり、環境中に戻したカルシウム塊Cを生物が再び成長過程で取り込むことにより、環境におけるカルシウム及び二酸化炭素の新たな物質循環に寄与することが期待できる。
