We had some old Cesium sealed sources at our research lab in Chicago and ADCO handled the entire radioactive waste disposal process with precision and expertise. Quick response time, clear communication, and fully compliant service. We highly recommended for ADCO for anyone with radioactive waste needs in the Chicago area.

We used ADCO for a full lab cleanout during our campus renovation. They helped categorize all waste, including chemicals, lab packs, and radioactive materials. The team was punctual, careful, and incredibly thorough. If you’re looking for a reliable partner for lab waste removal, this is the company to call.
As a small commercial generator, finding a reliable hazardous waste disposal company that actually understands RCRA rules and can handle mixed streams without turning every job into a paperwork nightmare is tough. ADCO made the whole process straightforward.
We had a mix of flammable liquids and other regulated materials from a job site that needed proper disposal. They walked us through waste profiling, got the streams approved, and handled the lab packing and DOT shipping paperwork so we stayed fully compliant. Pickup was on schedule, the crew was professional, and everything was documented cradle-to-grave. No surprises on the manifests or final disposition.
Communication was clear the whole way, pricing was fair for a licensed transporter, and they treated us like a real customer even though we’re a smaller operation (VSQG level). If you generate hazardous waste and need a company that knows the regulations and actually gets the job done right, ADCO is solid.
Highly recommend.

We had a storage area filled with over 300 gallons of leftover and expired paint from multiple renovation jobs. we weren’t sure what was still compliant or how to even begin getting rid of it all. I contacted ADCO after finding them online, and they helped us take inventory, and walked us through how to label and store everything before pickup. Everything was sorted and disposed of properly, and we received the disposal certificate without having to chase them down.
