Methane digesters

Anaerobic digesters control decomposition of organic waste, and convert methane emissions into biogas, an alternative fuel, and digestate, a nutrient-rich fertilizer.

One option is to control decomposition of organic waste in sealed tanks called anaerobic digesters. They harness the power of microbes to transform scraps and sludge and produce two main products: biogas, an energy source, and solids called digestate, a nutrient-rich fertilizer. The digestion process unfolds continuously, so long as feedstock supplies are sustained and the microorganisms remain happy.

When produced at scale, biogas can displace dirty fossil fuels for heating and electricity generation.
