- Assuming waste not recovered all goes to landfills. Determine the total landfill capacity consumed national wide each year. The specific weights of waste at landfill are as follows. Convert your answer to # of football stadiums filled. Area of football stadium = 1.75 x size of a standard football field Depth of filling = 30 ft Waste category Specific weight (kg/m³) Aluminum 2470 Steel and other metals 7100 Glass 2300 Paper and cardboard 570 Wood 450 All others ~700arrow_forwardFrom the following date, estimate the unit waste disposal rate per week for a residential area consisting of 1200 homes. The average occupancy is 4 persons per home. The observation location is a local transfer station that receives all of the wastes collected for disposal. The observation period was one week. Data: Number of compactor truck loads = 10 Average size of compactor truck = 20 yd³ Number of flatbed loads = 6 Average flatbed volume = 3 yd³ Number of loads from individual residents' private cars and trucks = 20 Estimated average volume per domestic vehicle = 9 ft³arrow_forwardQuestion 1 Municipal solid waste is generated within a community from several sources, not just the List and discuss these sources. In the town of Abesim, it is determined that the per capita waste generation rate is 1.4 kg(3.1 lb) per person per day. The collection is conducted once per week by the municipality. If the density of MSW in a typical trash container is 150 kg/m3, how many 120 L (30 gal) containers would be needed for a family of four? From (b), collection trucks have a capacity of 11.5 m3(15 yd3), which can compactthe waste to a density of 420 kg/m3. How many customers can a truck handle in a single run, before departing for the transfer station? In your community, is waste collection carried out by the municipality or by a privatehauler? Who collects the commercial wastes?arrow_forward
- The population in Camilia Apartment is 3500 and solid waste is collected on Sunday and Wednesday in the morning. Determine the waste generation rate by using data in TABLE Q4 (b). Determine the volume of storage containers that required for the apartment with density of waste is 310 kg/m³.

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 Checkarrow_forwardA landfill with capacity of 26,220 yd and a maximum height of 20 feet, serves a population of 80,000 persons with a waste generation rate of 4.1 lb/capita/day. If the average final specific weight of the waste placed in the landfill is 1200 lb/yd, estimate the amount as delivered waste (expressed in yd') with an average density of 500 lb/yd', that can be placed in the landfill assuming that 30 % of the original waste will be lost through production of landfill gasarrow_forward
- 13- (a) You are about to set a water balance for a sanitary landfill. Draw a definition sketch for a water balance to be used to assess leachate formation in a landfill. (b) Estimate the weekly volume of solid waste being delivered to a municipal landfill if the average solid waste generation rate is 2.6 kg/person.d. The population is 17,200 and the density as delivered is 122kg/m3. (c) The EPA Landfill Gas Emissions model, LandGEM model for estimating methane production from a sanitary landfill advocates22 the following equation: ne QT = E 2k L M, e- kti i=1 %3Darrow_forwardA city generates waste at a rate of 7400,000 kg/day. The density of the compacted waste is 380 kg/m3. How large should they build a landfill to contain a decade's worth of waste if the ratio of cover to compacted fill will be 1.5? Give your answer in m3arrow_forwardIn 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)?\arrow_forward
- 2. The maximum amount of solid waste collected per day for one week is presented below. All the solid waste are to be burned at a municipal waste to energy combustion facility at a constant rate of 100 tons/day. What is the required capacity of the storage pit that should be designed to accommodate twice the required daily capacity Day Solid waste collected (tons/day) Monday 150 Tuesday 130 Wednesday 120 Thursday 120 Friday 100 Saturday 80 Sunday 0arrow_forwardAccording to the U.S. EPA, what is the current cost per ton for disposal of municipal solid waste in a landfill to the nearest $10/ton?

The waste discharge is 7 million gallons per day containing 35 mg/l, while the stream has zero concentration with a flow above the sewer outfall of 102 ft/s. If the mean velocity in the river is 0.8 ft/s, calculate the distance downstream that the chemical residual persists.arrow_forward
