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 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?

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.
(b) 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? (c) From (b), collection trucks have a capacity of 11.5 m³(15 yd³), which can compact the 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?
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.
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 kg/m3 Daily generation of wet solid waste = 2200 kg Moisture content of the wet solid waste = 32% (ii) Determine X% and estimate the dimensions of the landfill site if the length: width : depth = 6:5:4
The 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.

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.
