(10 points) 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 500kg/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 you compost for $80/m3 and the density of the finished compost is 400kg/m3
