Brazil has long boasted a comparatively clean energy matrix, thanks to significant hydroelectric power output in the country. However, as climate change makes hydro an increasingly unreliable power source – and pressure grows for countries to diversify and clean up their energy mix – attention is turning to alternative renewables. One of these is biogas, and its purer derivative, biomethane. 

Biogas is obtained from organic waste – typically agricultural crops, animal manure, household waste, and human sewage – which undergoes a process known as anaerobic digestion to separate the gasses from the organic matter. The resultant biogas is composed of...
