Solid Waste Engineering
- Column 1 represents the fraction of the SW type in the total SW, Column 2 shows how many percent of the type of SW was recycled/recovered, Column 3 represents how many percent of the type of SW was combusted, and Column 4 shows the density of the type of SW. The volume of waste residue after combustion was negligible. 1) What is the total volume of SW that was landfilled? What is the average of density of the SW that was landfilled? 2) Usually, SW was compacted by some special equipment before landfilling. Also, because of the gravity from the other SW and cover material that was located above, the SW in a landfill was compressed, more or less. As a result, the volume of SW was decreased. Different sorts of SW exhibit different volume reduction behaviors. Column 5 is compact ratio, indicating the volume reduction. Compaction ratio = Volume before compaction/Volume after compaction. Please compute total volume and the average of density of the COMPACTED SW that was landfilled. 3) How…arrow_forwardA sample of dry solid waste has the following composition: 531 g carbon (C), 133 g hydrogen (H), and 335 g oxygen (O).

- The Tatooine community will landfill plastic along with the inert material and rubber. Assuming that inert material and rubber together account for 54.8% of the remainder waste, determine the volume of the landfill if it is to operate for 24 years. The density of the compacted waste is 895 kg/m³. Recall that the community has a population of 600663 residents and generate 0.7 kg of solid waste per day per person. The main waste fractions are shown in the table below: Waste fraction Food waste Paper Plastic Yard waste Percent (%) 41.1 19.8 13.9 8.4 The remainder of the waste consists of metal, glass, inert material and rubber. Answer: * Om^3 Okm^3 You did not give the correct unit. The volume of the landfill is determined by calculating landfilled portion of the waste, that is the plastic content + the inert and rubber portion of the waste.

- Which parameters may have effect on the bulk density of municipal solid wastes? Explain it by giving examplesarrow_forward3. A MSW facility is designed to handle solid waste generated by a town at a rate of 75,000 kg/d. The waste is delivered by compactor truck 4 days/week, and 30% of the waste is recycled. The density of the disposed waste before compaction is 120 kg/m3. The waste is compressed to a compaction ratio of 4.0. Daily cover takes up 20% of the total landfill cell volume, and a single lift is 3.5 m high. Engineers have designed the landfill for two lifts, and a total of 6.0 hectares are available for this MSW landfill.
