“…As most cities in Japan still consider waste generation, separation, collection, recycling/treatment, and disposal as independent operations, and yet, these components are closely interlinked ( Figure 2). The recent developments in Japan have been towards promoting different national policies that place a high emphasis on the recovery of carbon-rich and biodegradable waste through material recycling [6,38]. Amidst these national policies is the promotion of the utilization of a recyclable food waste act known as the Food Recycling Law; the Sound Material-Cycle Society in the act references the Biomass Nippon Strategy [6,14,38].…”

The long-term plan of any city in Japan is to become a material recycling society. The use of all types of municipal waste is essential in maximizing the full potential of material recovery. As such, municipalities are responsible for managing their waste, including food and biodegradable waste (FBW), and this results in some complex schemes. This study uses the system dynamics approach to illustrate and investigate the benefits of separate treatment of FBW. At the same time, to understand the dynamic interactions between all aspects and elements of the current municipal solid waste management system in Oita City. The developed model includes total environmental benefit, motivation to manage waste and resources, and yield from treatment facilities. The result shows that with the introduction of an anaerobic digester (AD) plant for FBW increases the efficiency of incineration. Furthermore, the result indicates that strengthening the regulation of waste sorted and the reduction in the amount of FBW treated in incineration will improve the current system. This study concludes that any policy or regulation less than the proposed result will yield less benefit. Thus, strengthening regulation is a crucial part of the sustainability of FBW management in the long run.

“…Currently, there is an increasing demand for the proper integration of effective policies that aim at practicing sustainable waste management in the main waste stream [5][6][7]. To this end, the Japanese government legislated the Act on the Promotion of the Recycling of Recyclable Food Resources, titled the Food Recycling Act (the Sound Material-Cycle Society in the act mentions the Biomass Nippon Strategy) in 2001 and reviewed it in 2015 [5,6,8].…”

“…Despite the sound support in favor of material recycling and recovery, reinforced by legislation, incineration continues to serve as the chief and the predominant source of MSW in most cities in Japan [7,[11][12][13]. FBW exerts a straightforward and substantial impact on the volume and structure of MSW, and constitutes the most sizable share mix with a low calorific value and high water content [14].…”

“…For this purpose, this study assessed the suitability of FBW treatment technology in Oita City, employing an analytic hierarchy process (AHP) benefit-cost analytical approach. The focus was on the FBW treatment methods endorsed in the Food Recycling Act, which include incineration with heat and electric energy recovery; landfill, which lacks any kind of energy retrieval; composting; and anaerobic digestion [7,8,25].…”

A Benefit–Cost Analysis of Food and Biodegradable Waste Treatment Alternatives: The Case of Oita City, Japan

As the generation of food scrap, kitchen, and biodegradable wastes increases, the proper handling of these wastes is becoming an increasingly significant concern for most cities in Japan. A substantial fraction of food and biodegradable waste (FBW) ends up in the incinerator. Therefore, an analytic hierarchy process (AHP) benefit–cost analysis technique was employed in this study to compare different FBW treatment technologies and select the most appropriate FBW disposal technology for Oita City. The four FBW treatment options considered were those recommended by the Japanese Food Waste Recycling Law: anaerobic digestion, compost, landfill, and incineration, which is currently in use. The fundamental AHP was separated into two hierarchy structures for benefit analysis and cost analysis. The criteria used in these two analyses were value added, safety, efficiency, and social benefits for benefit analysis, and cost of energy, cost of operation and maintenance, environmental constraints, and disamenity for cost analysis. The results showed that anaerobic digestion had the highest overall benefit while composting had the least cost overall. The benefit–cost ratio result showed that anaerobic digestion is the most suitable treatment alternative, followed by composting and incineration, with landfill being the least favored. The study recommends that composting could be combined with anaerobic digestion as an optimal FBW management option in Oita City.
