The widespread adoption of biogas as a reliable alternative energy source seems like a nobrainer. Capturing energy rich methane produced from decaying materials is a proven technology yet its adoption as part of the renewable energy mix appears to have been overshadowed by wind and solar.
And by 2050, waste generation in Sub-Saharan Africa is expected to more than triple from current levels.
Plastics are especially problematic. If not collected and managed properly, they will contaminate and affect waterways and ecosystems for hundreds, if not thousands, of years. In 2016, the world generated 242 million tonnes of plastic waste, or 12 percent of all solid waste, according to the report.
What a Waste 2.0 stresses that solid waste management is critical for sustainable, healthy, and inclusive cities and communities, yet it is often overlooked, particularly in low-income countries. While more than one-third of waste in high-income countries is recovered through recycling and composting, only 4 percent of waste in low-income countries is recycled.
