The good news is promising contemporary technologies may soon improve our ability to sustainably manage waste.
— use thermochemistry to turn waste into energy. “In pyrolysis we use heat energy in an inert atmosphere … [to turn] solid organic material [into] bio-oil, biochar and gases,” says Sonil Nanda, director of research and development at Titan Clean Energy Projects Corporation in Canada.
“It has properties almost equivalent to that of coal,” Nanda says. But make no mistake, biochar has no relation to coal, which is a versatile but far dirtier material.an additive to improve soil fertility, a filter for drinking water and perhaps most importantly, a clean biofuel. “The Intergovernmental Panel on Climate Change is now recognizing biochar as a carbon-negative material,” Nanda says. “Biochar holds a lot of promises for the future.
Waste management also intersects with other issues in these countries, such as labor rights. Dangerous labor is often performed at dumps by informal workers known as. These workers often have few legal protections, but their rights and well-being can be incorporated into larger waste management policy solutions. “There are some places where … a group of informal workers may be given the whole collection contract,” Kaza says. “It really depends.
Solid waste management is a global issue, intersecting with other challenges such as climate change, environmental health, environmental justice and civil rights. Promising new technologies may soon help us recover more clean energy from our waste, but we can’t ignore
