The University of Maine Cooperative Extension will begin collection of greenhouse plastic for recycling Friday, Sept. 25, with 16 drop-off sites across the state. Disposal is free of charge through Tuesday, Dec. 15, to all Maine growers who register, according to a news release from the Orono-based extension office.

The target material for recycling is clear, low-density, polyethylene (LDPE#4) plastic typically used to cover greenhouses, high tunnels, hoop houses and other agricultural structures. Collection sites also can accept white over-wintering LDPE#4 film used by the nursery industry. Materials not being accepted include black plastic field mulch, irrigation tape, silage bales and other types of agricultural plastic, and non-agricultural LDPE#4 films such as boat wrap and construction plastic.

The pilot project was developed by UMaine Extension and funded by a Maine Department of Environmental Protection Waste Diversion grant. Affiliated partners donating additional time and resources include the Maine Organic Gardeners Association, the USDA Natural Resources Conservation Service in Maine, and the Maine Resource Recovery Association.
