Chapter 10 Disposal of Solid Wastes and Residual Matter
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.
The landfill site is to be used for 13 years

A landfill is proposed for the area shown on the above map. Why might this not be a good location?
Where might there be a better place? What are the advantages and disadvantages of the new location?
Some relevant facts: groundwater at the proposed landfill site is 5 feet below the surface; the soil is
sandy from - 30 feet to +20 feet and sandy loam above 20 feet. Relate the above questions in terms of
the TN landfill regulations.

- List the 5 critical elements of a municipal landfill based on many current State requirements.arrow_forwardTwo small communities, Alpha and Beta, each have a small landfill. They are considering building a joint landfill to serve both communities (Fig. 3-30). a) , Write an objective function that can be used to minimize the total cost of disposal where the towns would have the option of taking the refuse to their own landfill or to the common facility. They will not be able, however, to take the refuse to each other's landfill. Use the following variables, and state all constraints: k.c F = fixed-cost for landfill k ($100,000 per year, regardless of size); subscript c stands for capital c = transportation cost from town i to landfill k ($2/km/ton) W = refuse generated in town i (2000 metric tons per year for Alpha, and 3500 metric tons per year for Beta) F = operating cost of landfill k ($10/metric ton) Hints: You'll need to include the transportation distance in the standard objective function, since transportation cost is a function of distance. You'll need to add Fto the objective…arrow_forward5. 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 FALSEarrow_forward

A sanitary landfill has available space of 16.2 ha at an average depth of 10 m. Seven hundred sixty-five (765) cubic meters of solid waste are dumped at the site 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.arrow_forwardCan 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.arrow_forward
- 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.arrow_forwardDiscuss at least two aspects of concern of a municipal waste landfillarrow_forwardDetermine 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.arrow_forward

The refuse (i.e., waste) field capacity is 305 mm/m and the moisture content of the refuse is 180 mm/m. Calculate how many years it will take for the moisture front to move through the landfill and produce leachate.
