“…In comparison to other processes, anaerobic digestion has the advantages of adapting to different work scales, treating a wider range of substrates, even with high or low moisture and impurities content [ 9 ], resulting in low environmental impacts [ 10 ] producing material able to be used as biofertilizers [ 11 ] and having high energy recovery potential [ [11] , [12] , [13] , [14] ].…”

“…However, questions related to the final disposal and treatment of municipal solid waste (MSW) constitutes one of the most serious problems of contemporary societies. About 50%-60% of MSW is usually composed of biodegradable organic waste such as food waste, garden waste, paper and cardboard waste, referred to as the organic fraction of MSW (OFMSW) [1,4,5]. Anaerobic digestion (AD) has proven to be promising for the treatment of organic waste streams, supporting renewable energy generation, while avoiding the risks of uncontrolled greenhouse gas emissions that results from landfilling [6].…”

The aim of this study was to treat food waste containing 25% total solids (TS) through dry anaerobic digestion (dry AD) process at various pressures (0.5 to 2.5 kg/cm2) and different time duration (20 to 100 min) to understand the impact of pretreatment in enhancing the methane generation potential along with insights on scale up. The findings revealed that vs. reduction and methane yield of 60% and 0.25 L CH4/(g VSadded) can be achieved with pretreated food waste at two kilograms per square centimeter, while pretreatment of food waste at 2 kg/cm2 for 100 min enhanced the vs. reduction from 60% to 85% and methane yield from 0.25 to 0.368 L CH4/(g VSadded). However, the net energy indicated that 40 min of pre -treatment at two kilograms per square centimeter can be a suitable option as methane yield and vs. reduction of 0.272 L CH4/(g VSadded) and 70%, respectively was achieved. The vs. reduction and the methane yield of 45% and 0.14 L CH4/(g VSadded), respectively was obtained from untreated food waste which illustrated that pretreatment had significantly impacted on the enhancement of methane generation and organic matter removal which can make the dry AD process more attractive and feasible at commercial scale.

“…For large‐scale industrial wastes, the several successful cases include the recovery of inorganic waste, such as valuable metals, from batteries and electronic devices ; the recycling of polymer wastes ; and the conversion of organic wastes into bioenergy in the form of hydrogen, bioethanol, and biodiesel . Furthermore, advancements have been made in biorefinery . In smaller‐scale systems, such as household waste or waste from restaurants and hotels, composting seemed to be common where space is not restrictive.…”

In this study, two in‐vessel composters with a turning device aligned horizontally or vertically were compared for their performances in composting food waste. Both composters were operated in batch mode at the fixed temperature of 55–60°C, and biological digestion was allowed to take place for 6 days. Both composters exhibited comparable performance with similar CO2 evolution characteristics and similar composted food waste properties, including moisture content, C:N ratio, electrical conductivity (EC), and pH. However, the reactor with the horizontal agitator provided a better stability of the final product, as the product from the vertical composter had traces of post‐anaerobic reaction. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1901–1907, 2018
