Estimate the area and volume of landfill to handle the solid waste from Warriorville for20 years. Based on a 10 yd sample of waste collected from an existing landfill during normal off‐loadingoperations. Assume the following:1. Population of 14,5662. Average solid waste generation rate of 2.42 lbs cap‐1 d‐13. Average uncompacted density of 9.03 lbs ft34. cell height of 8 ft 5. recommended depths of cover will be used6. normal compaction7. characterization of Warriorville solid waste based on a based on a 10yd dumpster sample isdescribed belowWaste Composition Mass (lbs)Food waste 56.5Paper and Cardboard 120.8Plastic 10.1Rubber, leather, wood 26.7Textiles 23.1Metals (90% Ferrous) 45.2Glass 30.6Miscellaneous 54.5
Determine the area required for a new landfill site with a projected life span of 35 years, for a population of 200,000 generating 2.02 kg /capita/day. The density of the compacted waste is 470kg/m³. The height of the landfill cannot exceed 16 m.
A sanitary landfill is being designed to handle solid waste generated by the town of Pietro, at a rate of 40 Mg/day. It is expected that the waste will be delivered by compactor truck on a 5 days/week basis. The density as spread is 129 kg/m3. It will be spread in 0.8 meter layers and compacted to 0.3 meters. Assuming 2 such lifts per day and a daily cover of 0.13 meters, box your answer the annual volume of landfill consumed in cubic meters. Ignore the soil volume between the stacks. Answer in two decimal value.Also In your solution Compute also the daily horizontal area covered by the solid waste.
Determine the area (m2) required for a new landfill site with a projected life of 10 years for a population of 100,000 generating 2.00 kg/capita-day. The density of the compacted waste is 400 kg/m3. The height of the landfill cannot exceed 10 meters.
10.7 A). Determine the impact of a resource recovery program on landfill area requirement, in which 40% of the paper, 60% of the glass, and 80% of tin cans are recovered. Knowing that the previous land fill was designed for a city of 40 000 in population, Amount of waste generation = 2.5 kg/capita/d refuse is filled into a depth of about 3 m.

• What is the total area required by a city of stable population of 350,000 to provide ten years of landfill disposal capacity for MSW generated by this population. The studies showed that the generation rate in this city is 4.4 Ib/person/day and the design of the landfill can be 50 ft average depth. The in place density of the waste will be 950 Ib/yd³. The auxiliary facilities (buildings, roads, equipment, maintenance, storage, etc) will account for 50% of the actual site area. (27 ft³ = 1 yd').
5. For preliminary planning purposes, estimate the required landfill area for a community with a population of 31,000. Assume that the following conditions apply: Solid waste generation = 6.4 Iblcapita.day; Compacted specific weight of solid wastes in landfill = 800 Ib/yd3; Average depth of compacted solid wastes = 30 ft. Based on the given data, the area required per year is 1.87 acre/year. O TRUE FALSE
A sanitary landfill has an available space of 12.5 ha for the dumping of solid waste. On average, 640 m³ of solid waste is dumped at the site 5 days per week. This waste is compacted to twice its delivered density. If a landfill is to be designed for 10 years, the average depth of the landfill required is.
A sanitary landfill has available space of 16.2 hectares at an average depth of 10 m. 765 m3 of solid waste are dumped daily at the landfill 5 days per week. This waste is compacted to twice its delivered density. Draw a mass balance diagram and estimate the expected life of the landfill in years.
Can I get a thorough step by step for the following question? A sanitary landfill has available space 25 ha at an average depth 12 m. Nine hundred sixty-five (965) cubic meters of solid waste are dumped at the site each day for 5 days per week. This waste is compacted to twice its delivered density. Draw a mass-balance diagram and estimate the expected life of the landfill in years.
Suppose a city of 50,000 people generates 40,000 tons of MSW per year. At current recovery and recycling rates, 22 percent of that is recovered or recycled and the rest goes to a landfill. Suppose also that the landfill density is 1,000 lb/yd^3, cell depth is 10 ft, and 80 percent of the cell is MSW.(a) What lift area would be required per year?(b) If the current landfill site covers 50 acres, including 10 acres needed for access roads and auxiliary facilities, and two more lifts are envisioned, how long would it take to complete this landfill?
(ii) The Kumasi landfill serves a population of 253,000. Each week 325 trucks bring a total of 2180 tonnes of MSW to the landfill. Each truck averages two loads per day. The trucks each has a capacity of 4.5 tonnes, and operate 5 days per week. (a) How much MSW is generated per person? Give your answer in kg.capta-1.day. (1 tonne = 1000kg). (b) What is the average load (in metric tonnes) in each truck when they at the landfill? At what capacity are the trucks operating? (c) If the density of the waste is 265kg.m-3, what is the volume of the MSW disposed of at the landfill each week?
