  • Preserving forests while emptying trash cans? The story of a Burkinese green charcoal

    To preserve the millions of trees that are cut down just to produce coal in Burkina Faso, a Burkinese engineer created "green charcoal that would not only protect forests but also help fight against the proliferation of garbage." This ecological fuel is made from carbonized collected garbage and coconut husks, which in turn has reduced the amount of garbage that has to be managed by the authorities in charge of sanitation.

  • On the Delaware, A Promising New Era in Cleanup of an Urban River

    Once known for being dirty, the Delaware River is being cleaned up by nonprofits and government entities to the point where they’re encouraging people to swim in it again. The Camden County Municipal Utilities Authority diverted the flow of sewage at 52 municipal plants to a new treatment plant, which has kept 15 million gallons of sewage out of the river each day. While overflows have not been completely eliminated, a national advocacy group even named the Delaware its River of the Year because of its improvements in water quality.

  • How the World's Largest Garbage Dump Evolved Into a Green Oasis

    The former Fresh Kills Landfill in Staten Island is turning into a public park that will accept visitors in 2021. By capping the trash site with plastic, covering it with soil, and planting native grasses, city officials are restoring the area’s former tidal wetlands and scrublands; nearly 314 plant and animal species have already been sighted. While the successful closing of the dump nearly 20 years ago means that the trash is being sent to other neighborhoods in the United States where people dealing with economic hardship live, the project could be a model for sustainability and urban renewal.

  • Could a Detroit Experiment Unleash the Power of Urban Soil?

    A multi-year experiment in Detroit is looking at environmentally sustainable ways to build urban soil. Some urban farmers are concerned about the high alkalinity levels in their soils, which can lead to potentially contaminated produce. The project is studying how cover crops, compost, and tillage can improve a piece of land. Early results suggest that these techniques can improve soils for agriculture but also improve the soil’s capacity to absorb carbon to mitigate climate change in major cities.

    Two organizations in Pakistan are working to tackle the country’s waste problem. Saaf Suthra Sheher in Islamabad set up partnerships with offices and schools to process their dry waste like plastics and glass. TrashIt, a Karachi-based group, collects organic waste from vegetable sellers and restaurants and then processes and sells it as compost. Although the two organizations can only process so much of the waste produced in cities, they argue that until an effective municipal waste collection system is implemented, they can educate individuals and businesses about how to recycle properly.
