The landfill volume required for dry solid waste generated by a food factory per year is 300 m3. After drying the wet solid waste from the factory X% of it is recycled, followed by 2.5X% diversion for composting and 400 m3 for incineration, before the remainder is sent to the landfill. Using the information given below: Density of dry solid waste = 460

A city of 223567 residents has a waste generation rate of 0.18 cubic meters per day per resident. Based on studies, 43.7%of the waste will be incinerated and the remainder will be sent to a landfill. Of the total waste that goes to the incinerated, 1203% by volume of waste is generated and must be disposed of the landfill. Please calculate the cost of the landfill to be constructed for this city. Assume the following: Compaction factor of 51% Depth of land is 3.3m Landfill life span is 5 years Landfill cost is $33523 per acre

Q: Assume a rough estimate of MSW composition is as follows: % by weight Moisture content (%) Paper (assume dry mass all cellulose, C6H10O5) 40 8% Glass 10 - Steel 10 - Aluminum 10 - Food waste (assume dry mass all sugar, C6H12O6) 30 80% a) If 20,000 metric tonnes of this waste is for anaerobic digestion, how much methane gas would theoretically be produced? b) If 20,000 metric tonnes of this waste is for aerobic composting. How much oxygen would theoretically be demanded?
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.
A city receives 42 tons per day of a solid waste stream with chemical formula C4H17O to their waste to energy facility each day. Estimate the air requirements to combust this waste in cubic ft per day. Assume specific weight of air is 0.075 lb/cu ft and that air is 21% oxygen by weight.
A city has a population of 50000 people and they consume an average 20 million m3 of natural gas per year. What fraction of this demand could be met by digesting the refuse from this community. Assume solid waste generation rate is 2kg/person/day, Organics are in the form of glucose whose organic proportion is 54.40 %.

Equal amounts of two types of waste are disposed into a section of a landfill. They both start producing gas at t=0. Assume first-order decay for gas production. Each type of waste can produce 150 L CH4/kg of waste. Waste type A produces gas with a half-life of 8 years, and waste type B produces gas with a half-life of 4 years. How long (to the nearest year) until 90% of the total gas has been produced? a. 0.8 years b. 6.4 years c. 7 years d. 27.6 years e. 20.4 years Check
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)?\
