Chemical processing corporation is considering three methods to dispose of a non- hazardous chemical sludge: land application, fluidized-bed incineration, and private disposal contract. The estimates for each method are shown. Land Incineration Contract First cost, RM Annual Operating Cost, RM per year Salvage value, RM Life, years Application 130,000 95,000 900,000 60,000 300,000 120,000 25,000 3 2 a. Determine which has the least cost on the basis of a present worth comparison at 10% per year. b. If the contract award cost increases by 20% every 2-year renewal, analyse whether the decision will change.
