Depending on the cost of the product, the money saved in pesticide costs alone through proper container rinsing could be significant. Containers should be rinsed immediately after they are emptied because residue can dry and become more difficult to remove. As a commercial hazardous material, a container cannot legally be placed in a landfill, recycled or burned except in hazardous waste facilities. This could become a tremendous financial and logistic problem for farmers. If properly prepared before disposal, the containers are considered to be non-hazardous by the U.S. Environmental Protection Agency and the Ohio Environmental Protection Agency.
Proper preparation means either proper triple rinsing or proper pressure rinsing.
At this level, it is safe to place the containers into disposal systems. Managing Empty Pesticide Containers Remove the cap. Rinse the cap into the spray tank. Dispose of the cap separately. Rinse the container immediately after emptying.
