Assuming a 5-day class week with solid waste pickups on Wednesday and Friday before class starts in the morning, determine the size of storage container required. Assume waste is generated at a rate of 0.11 kg/cap/day plus 3.6 kg per room and that the density of un-compacted waste is 120 kg/m3. Standard container sizes (m3) are as follows: 1.5, 2.3, 3.0, and 4.6. [Q]4: (a) What is transformation? Write down importance of waste transformation. (b) A total of 11 apartment complexes and commercial establishments have entered into a contract with a solid waste collection firm to collect their solid waste. A 20 m3 vehicle is available for collection. The discarded volume of solid wastes to be collected is 96 m3/week. If it is decided to have two collections per week, how many trips are to be made on a collection day? Also determine the size of the container to be provided. Assume that r = 2.5 and for simplicity, assume that each of the 11 sources contributes the same amount of solid wastes. Make any essential assumptions if necessary.
