CHAPTER 4 BIOLOGICAL TREATMENT OF SOLID WASTE
www.ipcc-nggip.iges.or.jpOverall, biological treatment of waste affects the amount and composition of waste that will be deposited in SWDS. Waste stream analyses (see example in Box 2.1) are recommended methodologies for estimating the impact of the biological treatment on emissions from SWDS. The estimation of CH. 4 and N 2 O emissions from biological treatment of ...
