You are tasked by the local authority with the planning of the collection and transport of solid waste in a small town. You have at your disposal, ordinary compactor trucks which can carry 5 tonnes of solid waste at a cost of RM20.00 per km. The authority is considering whether to build a small transfer station within the town. It is estimated that the transfer station will charge a fixed cost of RM15.00 per tonne. A transfer vehicle using containers can carry 20 tonnes of solid waste at a cost of RM10.00 per km. Calculate the costs per unit tonne of solid waste to be transported to a sanitary landfill 80 km away from the proposed transfer station. Evaluate whether the transfer station will make the cost more economical. Assume the average distance of waste collection to the transfer station is 8 km for each compactor truck journey.
