Ecosystem Impacts of Biomass Utilization - November 2002

In Japan, the use of biomass resources is progressing, with livestock excrement, food waste, and wood waste being recycled. Although 80% of livestock excrement is reused as compost, the problem of river pollution caused by composting has arisen, and appropriate management is required. More than 95% of food waste is incinerated or disposed of in landfills, again raising concerns about environmental impact. Much of the forest residue and construction waste is unutilized, and there is a need to effectively utilize this as an energy resource.

Plans are underway to provide 10% of Japan's energy supply through the use of biomass energy, but many challenges remain for this use, including technology, cost, and the development of outlets. The use of biomass is also expected to have a ripple effect on other Asian countries, and the biomass industry market could reach 10 trillion yen in 10 years.

The impact of the use of biomass on ecosystems is particularly serious in terms of water pollution caused by the conversion of biomass into fertilizer, and there are still issues to be addressed regarding the sustainability of agriculture and the maintenance of biodiversity. The appropriate use and management of biomass is becoming increasingly important from the perspective of environmental conservation.
