Collection and transfer of solid waste involves municipal collection services transporting waste to transfer stations. In Dhaka City, household, commercial, and industrial wastes are deposited into street collection bins and then transported by small vans to larger compactor vehicles. There is no formal transfer station system, but waste is brought to designated areas to be filled into compactor vehicles. These vehicles then transport the waste to its final disposal location.
