The Massachusetts Department of Environmental Protection does not allow collection of hazardous waste without special permitting and oversight, so most municipalities contract with a licensed hazardous materials handler to hold an annual collection event.
If you are unable to find a safe storage location until the Town's next scheduled collection event:
Offer usable material to friends, neighbors and local family members.
Ask a family member, friend, or neighbor to store the material and bring it to the next event on your behalf.
Consult this list of regional HHW collections and contact Amherst's recycling coordinator for participation and registration details.
