- From the following date, estimate the unit waste disposal rate per week for a residentialarea consisting of 1200 homes. The average occupancy is 4 persons per home. Theobservation location is a local transfer station that receives all of the wastes collected fordisposal. The observation period was one week.Data:Number of compactor truck loads = 10Average size of compactor truck = 20 yd3Number of flatbed loads = 6Average flatbed volume = 3 yd3Number of loads from individual residents’ private cars and trucks = 20 Estimatedaverage volume per domestic vehicle = 9 ft3arrow_forwardThe City of Forty-Five (population 465,565) has requested your assistance in evaluating its solid waste collection system. Determine the mean time per collection stop plus the mean time to reach the next stop, the number of pickup locations per load, and the minimum number of trucks the city must own. The City of Forty-Five collection data are as follows: Average truck capacity = 12.5 m3; Average observed compaction ratio = 2.87 Crew size = 2; Number of pickups = 1 /wk (no rear-of-house service) Average number of cans per stop = 2.63/wk at 0.1136 m3/can Average number of residents per stop = 5 Average uncompacted density = 105.76 kg/m3 Average transport time to disposal site including delays and dumping = 1.78 h/trip Average number of trips to disposal site = 2/d; Rest breaks = 2 at 28.0 min Average maintenance downtime = 37.0 min/d; Average workday = 8.00 h Average percent of trucks out of service for major repairs = 15.0% Number of workday per week = 5arrow_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 rate of percolation into a 12-m deep landfill is 248 mm/y. 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. Round your answer to one term past the decimal point.arrow_forward19.

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?arrow_forward
- A landfill initially received 10,000 tons/day of waste. This receipt rate increases 10% per year. The landfill is closed at the end of the fourth year. Calculate the yearly gas production for 20 years after opening. What is the peak gas production in m3/yr.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_forwardHow many residences can be served? If we have a compactor truck which has a capacity of 30 yd3, each truck makes 3 trips/day 5 days a week, each residence has 3 people and each person produces 4lbs of waste. The density of the compacted waste is 425 lbs/yd3.arrow_forward

Looking for alternative, how many compacted blocks of 35lb would the family produce if family had a home compactor along with the number of cans required? Subject: Environmental Engineeringarrow_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.
