As a first step of research on evaluating effectiveness
of distributed biomass recycling system of business facility or regional unit,
in this study, we estimated the quantity of biomass waste which is generated
from green area, agricultural field, and cafeterias on a big campus of Okayama
University. Each quantity of pruned fruits
branch, cut grass, rice straw, and animal waste was estimated by using the
calculation method of NEDO, crop waste was estimated by using a farm report published
by Faculty of Agriculture, and pruned and fallen leaves were estimated by using
the allometry method which estimates amount of leaves based on trunk diameter
and tree height. The amount of the
kitchen waste generated from university cafeteria was figured out by hearing to
university Co-op. As a result, it was
found that the amount of biomass waste generated on Okayama University campus is
1,454 ton/year. If the biomass is burned
or used for bio gas generation, the electricity generation will be 6,765
GJ/year.
