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)?

Mechanical Processes

In civil engineering, the materials have to undergo a series of manufacturing processes before using them in construction and structural applications. These manufacturing processes form the foundation stone of mechanical processes. Some of the civil engineering materials such as bars, metallic beams, metallic columns, surveying equipment, earthmovers, overhead cranes, structural and construction components, and even cement that is the most fundamental construction component need to undergo different manufacturing processes before they are ready to use. These processes are mechanical.
