ある。However, in recent years, as environmental problems have become more serious, various restrictions have arisen on disposal methods and reuse. For example, when plastic is incinerated, the amount of heat generated is large and can damage the furnace, and new equipment investment is required to strengthen the furnace's capacity. Regarding landfilling, the increase in waste in urban areas has led to the shortage of landfill sites, and problems such as waste being transported to other prefectures for landfilling and illegal dumping are also occurring. Furthermore, recycling for resource saving also requires transportation costs, and remolding requires capital investment.
