7-2. Estimate the maximum amount (by weight) of material that could be separated for recycling from residential MSW using a two-container system. What should be the size of the two containers? Use the waste composition given in Table 3-4, and assume that there are 3.1 residents per residence.
Problem 6-6 (assume the waste is fed to an anaerobic digester, not landfilled). Use the equation given attached. Find x (moles of CH4) for food and paper as well. Then based moles of methane (x), individually calculate methane generated for paper and food waste and then total it. Provide answers in tons.
2. A municipal solid-waste site for a city must be located at Site A or Site B. After sorting, some of the solid wastes will be transported to an electric power plant where it will be used as fuel. Data for the hauling of solid wastes from each site to the power plant are shown in Table below SITE B 3 kilometers P100,000 SITE A Average hauling distance Yearly rental fee for solid - P5,000 waste site Hauling Cost 4 kilometers P1.50 per m - km P1.50 per m - km If the power plant will pay P8.00 per mºof sorted solid waste delivered to the plant, where should the solid-waste site be located? Use the city's viewpoint and assume that 200,000 m3 of wastes will be hauled to the plant for one year only. What site must be selected? Show your computation and defend your answer. (20 points)
. For a composition of city waste given as (Paper, wood, cardboard) = 53%, (Garbage)=22%, (Ceramics, glass, crockery) = 10 %, (Metals) = 8 % and (Rubber, plastics, discarded textiles) =7 %. Population of the city is 4 million. The waste generation rater per person per year is 0.138 tons/capita/year. How much waste in tons can be recycled? How much waste in tons must be collected in order to keep the city clean?
