Abstract

Methane, a strong greenhouse gas, is released when food and garden waste (FGW) are not disposed of in a structured and sustainable manner. The goal of this study is to assess the biogas potential with equal proportions of garden waste (GW) and three different food waste (FW) digested in mesophilic conditions by anaerobic co-digestion (AcoD). The feedstock consists of GW and three different FW with rice as major, along with lentils with vegetables (VFGW), leafy vegetables (LFGW), and chicken (CFGW). The feedstock is also subjected to various pretreatment procedures, namely thermal at 100 ℃ for 30 minutes and mechanical (press extrusion). The thermal pretreated LFGW feedstock produced the maximum biogas, followed by CFGW and VFGW that had undergone conventional digestion without any treatment with 444, 185, and 168 mL/g VS fed, respectively. With conventionally digested LFGW feedstock, abnormal biogas generation was seen, which may have been caused by incorrect reactor installation. Pretreated feedstock produces two times more biogas than conventional digestion. The highest biodegradability for LFGW was achieved with thermal pretreatment, which made the reactor-ready organic matter available by the disintegration of the feedstock. Understanding the outputs by pretreatment of the feedstock envisages its potency for efficient biogas generation, making it an effective waste management strategy.
