What are the main sources of agricultural plastic waste?

The main sources of agricultural plastic waste include plastic films used for mulching, greenhouse films, plastic nets, and containers for planting and storage. Plastic mulch films are extensively used for weed control and moisture retention, leading to significant waste once they degrade or are replaced. Greenhouse films, which are crucial for controlled environment agriculture, also contribute to waste as they have a limited lifespan and need periodic replacement. Additionally, plastic nets used for crop protection and plastic containers for seedling and produce storage contribute to the overall agricultural plastic waste.
