In an industrial area, 101 tonnes of waste is generated per year. Of this waste, about 56 tonnes of energy intensive materialswere recycled, 17 tonnes of organic wastes were composted to produce fertilizer, and the remaining waste was disposed tolandfill. The substitution efficiencies of recycling and composting are 95%, and 70%, respectively. Determine the Zero WasteIndex (ZWI) of this waste management system. (dont write % after the number. If ZWI is 80%, just write 80. Calculate answer to 0decimal places)

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.
A town with 2,350 residents wants to establish a municipality owned and operated solid waste collection program. 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?
Using the energy content (wet basis) of the waste components given in the table below, calculate the overall energy content of the waste having the composition shown. You can assume 100 lb of waste to make this easier. Then determine the composition of the left-over waste if 80 % of the cardboard, 60% of the yard waste, 50% of the paper, 30 % of the metals and 20% of the plastics are recovered or recycled. How does this affect the total energy content of the discarded waste? How about the energy content per mass (wet weight)?
Can I get a thorough step by step for this question? Each month the speedy dry-cleaning company buys 1.75 barrel (0.28 m') of dry-cleaning fluid. The amount of fluid lost to the atmosphere as emission is 210 kg/month and the remaining remains as residue to be disposed of. The density of the dry-cleaning fluid is 1.5940 g/mL. Draw a mass-balance diagram and estimate the monthly % of mass residue to be dosposed of.
Estimate the total theoretical amount of air that would be required under aerobic conditions to oxidize completely an organic waste with a chemical formula of C120H180O80N2.
You are provided with the following information about a municipal wastewater treatment plant. This plant uses the traditional activated-sludge process. Assume the microorganisms are 55 percent efficient at converting food to biomass, the organisms have a first-order death rate constant of 0.050/day, and the microbes reach half of their maximum growth rate when CE 3059 Page 2 of 2the BOD5 concentration is 10.0 mg/L. There are 150,000 people in the community (their wastewater production is 225 L/day-capita, 0.10 kg BOD5/capita-day). The effluent standard is BOD5 = 20 mg/L and TSS = 20 mg/L. Suspended solids were measured as 4,300 mg/L in a wastewater sample obtained from the aeration tank, 15,000 mg/L in the secondary sludge, 200 mg/L in the plant influent, and 100 mg/L in the primary clarifier effluent. The mean cell residence time is 4.0 days. a. What is the design volume of the aeration basin in cubic meters?b. What is the aeration basin detention time? c. How many kg of secondary dry…
