Is Bioenergy a Sustainable Climate Solution?
Converting biowaste into biogas, via anaerobic digestion technology, is a strategy that could contribute to multiple U.N. Sustainable Development Goals and the Paris climate agreement.

Biogas has been used as an energy source for centuries, to warm bathwater or light streetlamps, for example. But it is our slate of 21st-century socioenvironmental challenges that have sparked greater interest in biogas production and technology especially the conversion of waste into biogas.
Organic waste disposal, a huge problem due to modern society’s soaring consumption patterns, could prove to be both an attractive and low-cost renewable alternative energy source and solution. In fact, biogas systems may potentially meet a variety of energy needs worldwide, while reducing waste streams and providing biofertilizer as a by-product.
