What is the required truck capacity in cubic meters? Which truck should be bought?
2) A family of five people generates solid waste at a rate of 2 lb./cap/day. Collection is once a week. How many customers can a 20-yd³ truck that compacts the refuse to 500 lb/yd³ collect before it has to make a trip to the landfill? (UoD, B.Sc. 2012).
5) Assume each household produces 60 lb of refuse per week. How many customers can a 20-yd³ truck that compacts the refuse to 550 lb/yd³ collect before it has to make a trip to the landfill?
(d) In your community, is waste collection carried out by the municipality or by a private hauler? Who collects the commercial wastes?
A municipal solid-waste site for a city must be located at Site A or Site B. After sorting, some of the solid refuse will be transported to an electric power plant where it will be used as fuel. Data for the hauling of refuse from each site to the power plant are shown in the following table: Site A Site B Average hauling distance 4.8 km 6.4 km Annual rental fee $40,000 for solid-waste $25,000 site Hauling cost $2/m²-km $2/m²-km If the power plant will pay $8.00 per cubic meter of sorted solid waste delivered to the plant, where should the solid-waste site be located? Use the city's viewpoint and assume 120,000 cubic meters of refuse will be hauled to the plant for one year only. One site must be selected.
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
The first decision to be made is how the solid waste container will get from the residence to the collection vehicle. Compare the advantages and disadvantages of the two methods of collection truck routing. i. Daily route method ii. Single load method
(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?
Household hazardous wastes are often found in a sanitary landfill in Malaysia. Explain a proper plan on how to stop this issue from being aggravated.
