Landfill and mixed wastes are more expensive to dispose of than sorted wastes, and also decrease the possibilities for recycling of wastes. This thesis aimed towards determining what the potential benefits could be with leasing a sorting site and whether or not Destroy RC AB should introduce a sorting site to their business from a primarily economic perspective. The materials included in landfill and mixed wastes were determined and were prioritized differently depending on the economic and environmental benefit from sorting and recycling each material. If a sorting site was introduced to Destroy’s network of processes, unsorted waste types would be sent to the sorting site from demolition sites instead of to landfill and recycling sites. Scenarios with different variations of amounts of wastes at the sorting site, compositions of wastes, truck types used for transports, and sorting speeds were studied and used for total cost analyses
