Q&A for How to Dispose of Hazardous Waste

Yes, but most of the time your community/city includes it in your trash rate. Contact your city and ask them.

Vomit is not considered hazardous waste. You can flush it down a toilet or just throw it away in the garbage.

No. Only some of the old models contain mercury. The latest models include fluorescent powder, which is a non-hazardous white powder.

If you can't flush it down the toilet, it's best to create a composting toilet. This will allow the feces and urine to break down.

Store the dirt in a special container and hand over to the waste management team in your locality.

The carpet is considered biohazardous material and should be handled by specialized personnel. Contact a service like 'Crime Scene Cleaners' in your area to manage the waste and contamination properly.

Since you likely represent a business, you'll need to pay for disposal. Many companies specialize in collecting oil and filters from businesses that generate such waste. Contact a local oil change service to find out which company they use. In my experience, a waste management company collected our oil, and drained filters were typically discarded. Nowadays, recycling options may be available.

You should contact your local university's chemistry department or the health department, as they often have resources for hazardous waste disposal. Many cities and counties have designated facilities or events for disposing of such materials safely.

Spraying a hairspray canister outside can contribute to environmental pollution; it's best to use it up as intended.

Contact a Department of Labor approved asbestos removal contractor, who will then take it to a waste disposal facility suitable for asbestos.

Pool supplies such as acid cannot be poured down a drain as simple wastewater (unless "trade effluent" consent is obtained from the local water company). Acids for use in pools must be disposed of through a licensed waste provider.
