For a city of 3 million individuals discard 4lbs of solid waste per capita. Thirty percent of this waste is diverted to recycling. The remainder is compacted to a density of 1300 lb/yd3 and is landfilled into two 12-foot lifts per year. Assume that 18% of the volume will be necessary for daily cover. Find:a) Volume waste + cover
In a suburban area of a city, the total time dedicated to waste collection is, on average, 100 times greater than the combined average time it takes for each stop's collection and the time it takes to reach the next stop. If a waste collection truck has a compaction ratio of 2 and can transport a maximum of 8 (m3) of compacted solid waste per trip, what is the truck's average load volume for each collection in (L)?\
(d) In your community, is waste collection carried out by the municipality or by a private hauler? Who collects the commercial wastes?
A landfill receives 10000tons/day of waste. This receipt rate increases 10% per year. The landfill is closed at the end of the fourth year. Using the exponential model calculate the yearly gas production for 20 years after opening. What is the peak peak gas production in m3/yr.
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.
Problem 2Approximately 30 kg of consumer products are brought into a home by its residents on a weekly basis. Two thirdsof this quantity are used as food, and about 2 kg of these products remain in the house. Every week, 75% of thewaste is collected at the curb, with the remainder sent to recycling.1. Plot the mass balance diagram of the house showing the mass of inputs, accumulations and outputs.2. Estimate how much solid waste the residents leave out to the curb each week.
If an industrial plant discharges an effluent with a solids concentrationat a rate of 5000 lb/day, and if each person contributes 0.2 lb/day, what isthe population equivalent of the waste?
. 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?
In your community, is waste collection carried out by the municipality or by a private hauler? Who collects the commercial wastes? Define the term; Reuse

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. Make the answer as detailed as possible.
