HHW Recycling Tips

How to Prepare HHW for Transport


  • Pack waste carefully in a box or plastic storage container to prevent spillage during transport
  • Do not mix chemicals! Arrange similar chemicals together when packing your car. Put pesticides together, solvents together, paints together in their own boxes
  •  Make sure chemicals are not leaking and lids are tightly sealed. If they are not sealed, place them in a separate container for transport
  • Keep products in their original container. Label materials that are not in their original container. If you do not know what the substance is, transport it in its own box and let us know it is an unknown substance
  • Place your box of household hazardous waste in the trunk of your car or in the bed of your truck
  • Drive directly to the HHW disposal site carefully and let staffed personnel unload your chemicals once you arrive
