Household Recycling

The Dassanach people of Sudan are one of the more intact cultural groups in the world. Once pastoralists, they now are primarily farmers due to the loss of their native grazing lands. Traditional or not, the Dassanach women are astonishingly creative in recycling throwaways into headdresses and necklaces made from bottle caps, watch bands, and SIM cards. With small towns and bars springing up near the Omo River settlement, bottle caps have become abundant—so abundant that the women are beginning to sell their headdresses to visiting tourists.

Waste production multiplied tenfold over the last century and will likely double again by 2025. Half or less of that waste is generated at the household level. Though the mix varies widely from place to place, in high-income countries paper, plastic, glass, and metal comprise more than 50 percent of the waste stream—all prime candidates for recycling.

Recycling can reduce emissions because producing new products from recovered materials often saves energy. Forging recycled aluminum products, for example, uses 95 percent less energy than creating them from virgin materials.

Managing household waste tends to be the responsibility of city governments, or of informal waste collection in lower-income cities. Leading cities achieve recycling rates of 65 percent or more. Effective strategies go beyond raising public awareness and include:

  • fees for landfill waste, while recycling and composting are free;
  • redeemable deposits paid at purchase (from bottles to electronics); and
  • programs that gather funds from manufacturers to cover recycling costs.

Collection, transport, and processing are, for the time being, largely powered by fossil fuels. Even still, recycling remains an effective approach to managing waste while addressing emissions. It also reduces resource extraction, minimizes other pollutants, and creates jobs.

Technical summaries for each solution will be available May 1, 2017.
