Contact your wastewater officials before pouring to determine if this recommendation is suitable to your area. Some products cannot be broken down by the wastewater treatment process and are discharged untreated into lakes and rivers. If you have a septic system, only dispose of small quantities down the drain and dilute with lots of water first. Generally speaking, empty containers can be thrown away. Liquids should never be disposed of in the trash.
Some products are acceptable for landfill disposal if they are hardened or dried up.
Contact your local officials before throwing any product of concern away. If you must wait for a collection program, store products safely in their original containers with the labels intact and out of the reach of children. Contact your local officials to find out when and where a collection may be held in your area. Read labels carefully, and call your local official for disposal advice. A toxic gas may result.
