Most construction and household debris loads without any trouble. The limits here come from Iowa law and from the transfer station's own refusal list.
Iowa keeps four categories out of land disposal: yard waste, baled solid waste, lead-acid vehicle batteries and waste tires. Whole tires cannot go into a sanitary landfill at all unless they have been cut down to eighteen inches or less.
The transfer station adds its own refusals, and several of them catch renovation work. It will not take lead-acid batteries, asbestos, fertilizers, paint, antifreeze, hazardous waste, or railroad ties. Nor will it take concrete, rock or dirt, which is the one that surprises people most, since a slab or a foundation removal needs a different destination from the rest of the job.
There is also a weight trigger on roofing. Shingles are accepted at the transfer station only when the load comes in under 500 pounds; anything heavier has to go to the county landfill on East Washburn Road in Waterloo instead. A full tear-off clears 500 pounds easily, so tell your account manager if roofing is involved and we will plan the destination before delivery.
Hazardous waste, liquids, solvents and fuel stay out of a standard container anywhere. Ask your account manager about anything in between.
