The HMM facility will accept all types of lead-acid batteries from households only. Please note that the Boulder County Recycling Center no longer accepts lead acid batteries.

Can I get free products for reuse? Residents can drop off and pick up reusable quantities of paints, stains, and other supplies from HHW during regular hours.
A.
Yes, the Hazardous Materials Management Program offers free products to the public during its regular hours.

The HMM Facility accepts many products that are in usable condition and some that have never been opened. Reusable products include: cleaning, automotive, hobby and pet products, paints, stains & varnishes, garden, woodworking supplies, wood sealants, etc. Suitable products are made available to individuals, businesses, and county and city departments for reuse. They are available free of charge on a first-come, first-served basis. All persons accepting products will be asked to sign a liability and indemnification release.

The HMM Program reserves the right to restrict or terminate access to these products in cases of overuse or abuse of this service.

Why does the program accept donations?
A.
In order to help fund this important service, the Hazardous Materials Management Program accepts voluntary cash donations from residents. A convenient donations box is available at the facility. Tax-deductible receipts are available on request.

Why should I take my fluorescent light bulbs to HMM? What happens to them when I take them to the Hazardous Materials Management Facility?
A.
Fluorescent light tubes are hazardous because they contain mercury vapor, small amounts of lead, and phosphorus dust. Do NOT break fluorescent tubes—this will release these hazardous compounds into the air. The HMM facility ships the light tubes to Arizona where the glass, metal and mercury are extracted for recycling.

Regular incandescent light bulbs cannot be recycled. They are not hazardous and can be disposed of with regular trash.

If I take my motor oil to HMM, what happens to it? Does it get used in the production of plastic?
A.
Oil collected at the HMM facility is currently sent to facilities around the country for use as an industrial fuel.

What happens to all of the other items taken to the Boulder County HMM Facility? How are they disposed?
A.
Wastes received at the Boulder County HMM facility are reused, recycled, used as fuel, treated, or disposed of in an environmentally-sound manner. HMM receives many products in good condition and makes these products available to the public free of charge for reuse. Rechargeable household batteries, lead-acid batteries, antifreeze, and mercury-containing products are recycled. Halogenated solvents (some wood strippers) are processed for chlorine recovery. Bulked flammable liquids and oil-based paints are used as energy-saving industrial fuels. Low BTU paint products (waxes and greases), oxidizers (bleach and drain cleaners), pesticides, and poisons are burned in an industrial incinerator using modern, clean air technology. Latex paints that are not reusable are solidified with cement kiln dust and landfilled.
