An affluent suburb in Johannesburg with a population of 35,000has a solid waste generation rate of 2.3 kg solid waste/day-person.Garden refuse makes up 23% of the total waste generated (byweight). Garden refuse is managed by a composting company whocollects the refuse separately. Assume the average density of thesolid waste is 140 kg/m3 and is compacted to 340 kg/m3 in the wastecollection truck that collects the waste at the home. Once thewaste is disposed of in the landfill, it has a density of 220 kg/m3.
a) Argue why affluent suburbs generate more waste than lesswealthy suburbs.
b) Given that the municipal landfill only receives waste fromthe suburb and has a total available volume of 300 000 m3remaining, determine how long (in months) will it take to reach themaximum capacity of the landfill.
