How to Recycle Wine Corks
Stoppers from wine and spirits bottles. Natural cork comes from the bark of the cork oak, which regrows after harvest. Synthetic corks are plastic.

Quick answer
Wine corks do not belong in curbside recycling. Natural cork goes in the compost or to a cork collection program, while synthetic plastic corks and screw caps follow different routes. Check the cork: natural cork is light, porous, and crumbles when cut. Before you go, confirm that a local recycling center accepts the material in its current condition.

Special Instructions
Corks are too small for curbside sorting equipment. Cork collection programs grind natural cork into flooring, shoe soles, and insulation. Aluminum screw caps belong with scrap aluminum, not loose in the cart.
Environmental Impact
Cork harvesting strips bark without cutting the tree, and cork oak forests store carbon. Recycling corks extends the life of that material.
Sustainable Alternatives
- Use corks for crafts, trivets, or bulletin boards
- Use chopped cork as garden mulch
