A yard waste composting windrow has a triangular cross section and is 10 feet wide at the bas and 10 feet high at the peak and 100 feet long. You may assume the waste has a specific weight of 400 lb/yd^3 as placed in the windrow. The waste material is 40-percent biodegradabl and has the ultimate composition of C60H95O40N. Determine the amount of oxygen required to stabilize the waste. Assume the aerobic degradation can be expressed as: (4а + b — 2с + 3d) (b – 3d\

s) You are setting up a composting batch and have 8 tonnes (metric tons) of poultry litter with a C:N of 14, a dry weight % of N of 2.7%, density of 500 kg/m³, and a moisture content of 33%. You are aiming for a C:N of 25:1 for optimal composting performance, so you are considering several options of other wastes to make up your batch. The following table shows the moisture content, C:N and cost per tonne of each material. You estimate that you will lose 20% of the initial mass during the composting process. Determine which would provide the best return on investment if you can sell your compost for $80/m³ and the density of the finished compost is 400 kg/m³.
