“…It is predicted that the amount of FW will increase sharply from 2.78 to 4.16 billion tons by 2025 in the Asian countries only [7]. FW is one of the main components of municipal solid waste, including household food waste, food-processing waste, canteen and restaurant waste [8]. Food waste mostly contains carbohydrate polymers (starch, cellulose, and hemicelluloses), lignin, proteins, lipids, organic acids, and a remaining smaller inorganic part.…”

Anaerobic Digestion Process of Food Waste for Biogas Production: A Simulation Approach

Anaerobic digestion (AD) involves a series of biological processes in which organic material is broken down and transformed into biogas. A simulation model of the AD process in treating food waste to produce biogas was developed using Aspen Plus software. The components list, thermodynamic property package, reaction list, reactor model, and process condition were specified in Aspen Plus. Sensitivity analysis was performed to study the effect of hydraulic retention time and changes in food waste composition on the biogas production. The methane composition in biogas decreased when the hydraulic retention time was increased which is due to the reduction of substrate consumption during the AD process. The process model is able to represent the AD process and provides a good approximation on the production of biogas under various process operating conditions.

“…During this process, macromolecular organic matter is broken into easily dissolved monomers and then smaller molecules of short-chain fatty acid, amino acid, pyruvic acid, acetic acid and so on. They finally are digested into hydrogen and acetic acids which are transformed into methane by methanogenic archaea [1], while FW is regarded ideal for AD biomethane potential estimated at between 200 and 670ml CH 4 /g added VS [7]. AD is drawing increasing attention because of its high valorisation value for waste and it offers opportunities for energy renewable and nutrient reclamation.…”

“…Xiao et al got the result that the biogas and methane yields of 0.759 L/g added VS and 0.454 L/g added VS in the TPAD were lower than those in the single-stage AD processes during the steady period, and the improper sludge retention time may be the reason for this lower methane production. On the basis of traditional single-phase AD research, two-phase anaerobic digestion system was considered as more efficient way to increase methane generation than a singlephase one by a lot of researches [1]. In a two-stage AD system, hydrolysis and acidogenesis happen in one reactor and acids utilization takes place in another one.…”

Abstract.Since a large amount of food supplying is provided as a basic line measuring increasing residents' life standard, food waste has become progressively numeral considerable. Much attention has been drawn to this problem. This work gave an overview on latest researches about anaerobic digestion, composting, generalized management and other developments on management of food waste. Different technologies were introduced and evaluated. Further views on future research in such a field were proposed. IntroductionFood waste (FW) is composed of household food waste, food-processing waste, canteen and restaurant waste, which is one of the components of municipal solid waste [1]. The accumulation of FW cannot be neglected because of tremendous environmental and sanitary problems with it. FW amount is estimated to quickly increase from 2.78 billion tons to 4.16 billion tons in Asian countries by 2025[1]. About 1.3billion tons of food, fully one-third of all food produced is lost along the food supply chain every year [7]. While economy is still accelerated, FW grows larger at the same time. However, it is significant to see that FW management also takes an important role in the renewable energy and sustainable development for values like Biomethane potential(BMP) of FW. With rising attention being moved on this field, technologies developments for this have been made continually.Anaerobic digestion (AD) has always been the hot research trend for its relatively costeffectiveness, renewable energy production and waste treatment of high-moisture and energy-rich material [2]. During AD process, biomass and organic fraction of municipal solid waste (OFMSW) can be converted into combustible biogas (mainly methane, and other gases like hydrogen and hydrogen sulfide) [2]. Parameters such as methane yield and volatile solids reduction or so were used to assess experiment performance. In order to enhance methane generation performance, various aspects of AD were researched. Additive supplementation, operational alternations, parameters optimization and microbial actions have been discussed by researchers. In addition to AD, composting, co-pyrolysis and other FW managements pathways also have been conducted to research results. At the same time, investigations and sorting systems were made for governments to implement better decisions on FW management. This paper aims to critically give an overview on latest research progress and novel developments of FW management in 2018. Further views on future research needs in such a field were proposed simultaneously.

Currently, sustainable societies require a reduction in general and food waste discharge, which is a major environmental problem. As food waste contains a high moisture content, anaerobic digestion is an effective way to recycle food waste that contains large amounts of moisture. While 70% of industrial food waste is recycled, only approximately 20% of household waste is recycled in Japan. In this study, we developed a microanaerobic digestion system with a capacity of 30 L and evaluated its basic performance by simulating a daily use situation. Biogas was produced, containing the same amount of methane as other systems. Although no mixing in the fermenter was done, the production efficiency of methane reached approximately at least 60% of the theoretical value of methane gas production for the chemical oxygen demand of the input food waste.
