They can purchase one of three possible trucks that have the ff. characteristics: Truck A, 18 m^3 capacity Truck B, 15 m^3 capacity Truck C, 12 m^3 capacity If the truck is to collect the refuse for one-fifth of the town each day during a 5-day work week, then every residence will be collected during the week, and the truck will have to make only one trip per day to the landfill. Which truck or trucks will have sufficient capacity. Assume a rate of 1.75 kg/capita/d. Assume that the truck is able to compact the refuse to 350 kg/ m^3 What is the total tonnage of solid waste to be collected/wk? What is the total weight of waste to be collected everyday? What is the required truck capacity in cubic meters? Which truck should be bought?

(a) 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? (b) From (a), 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?
Question 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?

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?
(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?
The 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 = 5
7-2. Estimate the maximum amount (by weight) of material that could be separated for recycling from residential MSW using a two-container system. What should be the size of the two containers? Use the waste composition given in Table 3-4, and assume that there are 3.1 residents per residence. Make the answer as detailed as possible.
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 ft3
In a suburban area of a city, the total time dedicated to waste collection is, on average, 100 times greater than the combined average time it takes for each stop's collection and the time it takes to reach the next stop. If a waste collection truck has a compaction ratio of 2 and can transport a maximum of 8 (m3) of compacted solid waste per trip, what is the truck's average load volume for each collection in (L)?\
How many cubic yard of solid waste can be placed on a regulation soccer field (200 ft × 300 ft) subject to the following constraints and conditions? Slope of all landfill faces = 3 to 1 Covered material will be excavated from the site Neglect cover material requirements Lift height = 10 ft Maximum height of landfill = 20 ft Waste generation rate = 4.1 lb/capita day Community population = 80,000 How many soccer fields would be required per year to dispose of the waste from the community, assuming the in-place specific weight of the waste is 1,000 lb/yd3?
How 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.
THIS IS NOT GRADED QUESTION, PLZ SOLVE IT AS SOON AS POSSIBLE. ENVIRONMENTALENGINEERING-2 Reg.NO: 5395 • In slide 2 and 3 increase the no of loads (Column 2) by 5. • Calculate the total load at the end of the day. • Calculate the capita (per home). The no of residences in the locality (from which the whole waste generates) is the last digit of your REGISTRATION NUMBER. For example, your registration number is19PWCIV 5395… the number of residences will be 5395
(d) In your community, is waste collection carried out by the municipality or by a private hauler? Who collects the commercial wastes?
