What's in your garbage?

Eighty percent of materials thrown away are resources – not waste.

Garbage today. What will it be in the future?

Some materials are not readily recyclable and are appropriate for disposal today. But with research and advancements in technology they could become resources tomorrow.

  • Non–recyclable paper – wrapping paper that is laminated or contains foreign materials such as foil-coatings or glitter, photographic film, microwave containers, hardcover books, frozen food boxes, thermal fax paper, carbon paper, blueprints, aluminum foil boxes and binders.
  • Treated or contaminated wood - wood treated with preservatives or attached to other materials like sheetrock or window glass
  • Non–recyclable plastic consumer items - some food storage containers, dishware, vinyl, disposable diapers, toys, Formica™, fiberglass, foam materials, and plastics attached to other materials such as kitchenware or auto parts
  • Non–recyclable glass – window glass, mirrors, light bulbs, and cookware
  • Other waste – ashes, soil, animal feces and carcasses, dirt, furniture, mattresses, and insulation

For now, it’s important to buy carefully, use and reuse, and find ways to reduce waste wherever possible.
