Can I get help for part B please.
Developing an effective strategy for managing food waste is an issue all solid waste professionals are facing. Many states have banned the landfilling of commercial food wastes. Based on the topics we've covered in class this semester, determine the emissions from the landfilling, composting, anaerobic digestion, and incineration of food waste. Use the numbers you calculate (all in m3 CO2-equivalents) to determine the preferred way to manage food waste. To help you structure your solution, please use the following information, and answer the specific questions a-e: Information given: Perform the calculations for a hypothetical city of 1,000,000 people. Assume each person generates 2,000 g waste/day. Assume 25% of this generated waste is food waste that needs to be managed. Focus all your calculations on 1 year's worth of waste. Answer these questions: a. Compute the emissions associated with composting all the food waste using a windrow system. Assume 85% of the waste degrades completely. Report your emissions in m3 CO2-equivalents. b. Compute the emissions associated with anaerobically digesting all the food waste. Assume 90% of the waste biodegrades. Assume a gas collection efficiency of 95%. Report your emissions in m3 CO2-equivalents c. Compute the emissions associated with landfilling all the food waste. Calculate emissions for 45 years. When performing these calculations, assume: • Lo = 300 m3/Mg • k=0.1 yr-1 • Gas collection efficiencies: years 1-3: 45%, years 4-8: 65%, years 9-15: 85%, and years 16-45: 95%. Report your emissions in m3 CO2-equivalents. d. Compute the emissions associated with incinerating the food waste. Assume all gases are scrubbed from the gas prior to existing the system, with the exception of CO2. Report your emissions in m3 CO2-equivalents. e. Based on your calculations, how would you suggest the food waste be managed? Why? Please be complete in your answer. I am expecting a small paragraph, not a word, phrase, or single sentence.
