Abstract

Food waste is daily generated in significant amounts around the world, implying the depletion of natural resources and the emergence of environmental pollution issues if discarded without valorization or utilization. In this regard, food waste management poses an important challenge in the circular society. Based on the official statistics and the national laws and regulations database in Taiwan, this study analyzed the on-line reporting amounts of collected food waste since it has been officially designated as one of the mandatory recyclable wastes. Furthermore, the regulatory measures for promoting food waste utilization in Taiwan were addressed to valorize it for the production of value-added resources and also prevent the spread of African swine flu. It showed that the collected amounts of food waste from residential and commercial sectors in Taiwan significantly increased from about 168,600 metric tons in 2003 to the maximal amount (i.e., 834,500 metric tons) in 2012, reflecting the regulatory promulgation and promotional measures. Based on the joint efforts by the central governing authorities (including the Environmental Protection Administration, the Council of Agriculture, and the Ministry of Economic Affairs), this study also examined the regulatory promotions for utilizing food waste as an available resource for the production of value-added resources (i.e., organic fertilizer, pig feed, and bioenergy). Through the central governing authority, local governments, and private recyclers, about 2000 metric tons of food waste in Taiwan was recycled every day, which can not only mitigate the pressure on waste incineration and disposal systems, but also conform to the trends of environmental sustainability and circular bioeconomy. Therefore, the Taiwan government is currently supporting the establishment of anaerobic digestion and aerobic composting plants for turning food waste into organic fertilizers and biogas-to-electricity because they have been evaluated as the best options of food waste valorization.
