Plastic Harvest Organizations

The Pesticide Stewardship Alliance

The Pesticide Stewardship Alliance logoThe Pesticide Stewardship Alliance (TPSA) was founded in 2000 as an organization of federal, state and local governmental agencies, educational and research institutions, public organizations, private corporations and individuals involved in many aspects of pesticide stewardship. TPSA has become the new Mecca for professionals working to recover value from used agricultural plastics. The organization initially focused on recycling of plastic pesticide containers, enhancing the pesticide industry's public image. Today TPSA is looking to include other agricultural plastic items that may have pesticide residues on them, including items PERCEIVED to contain pesticide residues.

The American Society for Horticultural Science

The American Society for Horticultural Science logo ASHS has recently embraced the American Society for Plasticulture (ASP) as a working group within. The ASP Working Group strives to improve the economic efficiency of horticultural systems (specifically) and agricultural systems (generally) through the use of plastics. This includes plastics in various aspects of plant and animal production, manufacturing, packaging, and distribution; and through environmentally sound recovery and reuse. This is accomplished by promoting plastics science and technology, by providing a forum for the exchange of plasticulture ideas and information, and by encouraging innovation.
