The Idaho State Department of Agriculture has a Container Recycling Operation (CROP) for clean, used HDPE (#2) plastic containers. In some cases, containers must be cut down in size to accommodate the opening of the chipper.
Unneeded pesticides in containers may be disposed of through the ISDA's Pesticide Disposal Program.
Containers must be empty, clean, inspected, uncapped, and dry.
- Clean: Read the label and any handling instructions for crop protection products and wear proper protective equipment as specified. Pressure or triple-rinse the container as soon as it is emptied. Dispose of rinse water with the spray mix.
- Inspect inside and out to ensure ALL formulation has been rinsed out, and no residue remains on the pour spout, spout threads and container wall surrounding the spout. The recycler cannot accept containers with dried formulation on them.
- Discard caps: Caps are usually made of a different kind of plastic and cannot be recycled. Be sure to clean the cap at the time the container is rinsed. NEVER put a cap back on a cleaned container. Dispose of cleaned caps as normal solid waste.
- Keep containers dry: Cleaned containers MUST be kept out of the rain and away from rain water. Even if it otherwise appears clean, the recycler will not accept crop protection products container that has liquid in it (the recycler has no way to dispose of the liquid). Store cleaned containers in a roofed building, an enclosed trailer, or in plastic bags.
There is no need to remove labels from cleaned containers. The recycler can process containers with labels attached. Containers that originally held products known to stain plastic (e.g. Treflan, Sonalan, etc.) are acceptable for recycling if the plastic is stained but otherwise clean (containers cannot have formulation residues or any liquid in them).
See the ISDA website CROP pages for more information, and collection locations and schedules.
