Hazardous Waste



 You may want to visit for paint disposal options in your area.

Riverside Recycling accepts household hazardous waste (HHW) on the 1st Saturday of the month (April through November.) Collection occurs from 7:30AM to 1PM.  This program is open to all Maine residents disposing of Household Hazardous Waste (HHW) from their residence. Portland E-Card holders may dispose of up to 10 gallons of HHW annually with a maximum of TWO visits at no charge (i.e. two visits of 5 gallons each visit, or one visit with 10 gallons will use up the HHW portion of your E-Card for the year). Acceptable paint, stain and varnish can be disposed of at no charge as part of the program and does not go against the HHW portion of your Ecard. Residential customers without an Ecard will be charged $6.50 per gallon for liquid wastes or $3.50 per pound for solid wastes. Unfortunately, we cannot accept hazardous waste from businesses or municipalities..

How will the drop off program work?

  1. Prepare your household hazardous waste for drop off.  When preparing hazardous items for disposal at the Household Hazardous Waste Facility, be sure that liquids are in sturdy leak-proof containers with caps or lids. Use the original container whenever possible. Secure breakable or loose items inside boxes or bags. Do not mix items together. Be careful that no items spill or break when they are in your vehicle.
  2. Bring your items to Riverside Recycling, 910 Riverside St. on the 1st Saturday of the month (April through November.) Collection occurs from 7:30AM to 1PM. When you arrive at the facility, stop at the attendant’s booth and speak with the attendant. ALL HAZARDOUS WASTE MUST BE DROPPED OFF BEFORE RECYCLING ANY OTHER ITEMS.
  3. Follow any directions you receive at the attendant’s booth and proceed into the facility. When you pull up at the HHW facility, stay in your vehicle. The HHW staff will handle removing your items for you.
