4. A spherical industrial landfill with radius of 500m and maximum waste depth of 60m is proposed for a potential site. The expected waste composition is provided by your client and is shown below. Compute the average bearing capacity of the foundation (in kPa) supporting the landfill. Waste component Percentage by weight (%) Compacted Unit Weight (kN/m3) 8 Textile Biodegradable plastics Waste wood Soil daily covers 45 18 22 15 3 11 27 5. Your client is also interested in building a gas management system for the proposed industrial landfill in Q4. Based on the landfill location and the expected waste composition, it is estimated that the annual LFG generation rate is about 6m per metric tonne of waste. Your client agrees to invest in the GMS project only if the annual LFG collection rate is at least 12 million cubic meter. If the landfill gas extraction efficiency is about 66%, advice your client on the GES project
