Abstract
In a recycling society, reduction of waste generation and promotion of recycling are required. Many municipalities introduce source separation and charging for gabage bags at the same time. Therefore, it is difficult to grasp the effect of only source separation or only charging on municipal solid waste treatment system. This study focused Tsuchiura City, Iabaraki prefecture that started source separation of food waste and container plastics in April 2015 and has a plan of charge for waste collection in October, 2018. Using actual data before and after the introduction of source separation, the effect of the source separation on the mucnicipal waste treatment system was clarified. Furthermore, a future effect of renewal of incineration facility and landfill site were considedered. As a result, the amount of household waste generation per person deresed because of the introduction of source separtion and the amount of landfilled waste also dereased. In future, considering the renwal of incineration facility and landfill site, although the cumulative costs will increase in case of introduction of source separation, the other criteria will be improved, such the net energy consumption, greenhouse gas emissions and the amount of landfilled waste.
