With regard to waste power generation in Japan, although average power generation efficiency for all existing facilities is currently only at approximately 11.9%, the rate for facilities planned for completion in the next five years is at 20% or higher, and the improvement in efficiency is definitely progressing. Given the scheduled completion of these facilities, which will combine incineration facilities with methane fermentation facilities and aim to be small-scale, high-efficiency power generation facilities with capacities of 100 to 200 ton/day, circumstances surrounding waste treatment are steadily undergoing change. In this paper, some of the contents of a manual for the preparation of energy recovery type waste treatment facilities, which started in FY2014 with the involvement of JEFMA, are introduced. These include EGR+SNCR, high-temperature high-pressure waste heat boilers, on-site catalyst denitrification regeneration, fly ash circulation, waste water recycling systems using membranes, and other technologies for further improvement in efficiency.
