Some of the largest volumes of waste farm plastic are silage wrap and empty agrichemical containers. Plastic takes a long time to breakdown in the environment and cannot be burnt because of the release of gases such as dioxin.
Dispose of your farm plastics at the local council transfer station. Agrichemical containers must be triple rinsed and punctured and cap removed (so the cap doesn't fly off and hit someone when it is crushed). Disposal in your own farm landfill is possible with restrictions.
