1. Explain why it is difficult to determine the engineering properties of municipal solid waste?

Question 4. Consider the liner system at the base and on the side slope of a landfill in figure below. State the function of each of the components. Give the common important / typical requirements or properties such as minimum thickness, permeability, etc. for each. Drainage Layer Geonet Compacted Clay Waste 00.0%% XXXX Subsoil geotextile geomembrane geomembrane

Describe the features of Municipal solid waste.

Describe two advantages of using a waste-to energy facility to deal with waste compared to traditional landfill.

I need the answer as soon as possible

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

If the BOD4 of a waste is 200.0 mg/L and the ultimate BOD is 270.0 mg/L, what is the rate constant at 10⁰C.

Sources of Municipal Solid Wastes and composition of the wastes

The majority of municipal solid waste is 64% paper. What ways would you suggest to reduce paper waste?

Loose refuse with no processing or compaction has a bulk density of A lb/yd³.
