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.
1. 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.

- Estimate the life of a landfill for a user population of 10,000. The available area for the are-type landfill is 10 acres. The water table is estimated at 6.1m(20ft) below the ground surface. The pit must have side slope of 1:3 and the final surface must have a slope of 1:4. Assume that soil (used as daily cover) occupies 20% of the compacted volume of wastearrow_forwardThe landfill volume required for dry solid waste generated by a food factory per year is 400 m3. After drying the wet solid waste from the factory X% of it is recycled, followed by 2.5% diversion for composting and 500 m3 for incineration, before the remainder is sent to the landfill. Using the information given below: Density of dry solid waste = 425 kg/m3 Daily generation of wet solid waste = 1500 kg Moisture content of the wet solid waste = 38% Determine X% and estimate the dimensions of the landfill site if the length:width:depth = 5:4:7. QUESTION 2. Estimate the theoretical amount of slow decomposable solid waste (C20H29O9N) required to produce 65 m3of methane (CH4) using the equation below. Assume a 75% conversion and the density of methane is 0.7167 kg/m3. Use the equation below C20 H 29 O9 N + 9H20 = 11CH4 + 9H20 + NH3 C = 12, N = 14, H =1, O = 16 QUESTION 3.
