Water treatment could be carbon neutral

Carbon dioxide released by some wastewater treatment plants could be recycled at the same time as enhancing the production of renewable energy in the form of natural gas, say scientists.

Engineers transform food waste into green energy

In a classic tale of turning trash into treasure, two different processes soon may be the favored dynamic duo to turn food waste into green energy, according to a new Cornell-led study in the journal Bioresource Technology.

Biogas from animal waste in need of maturity

Biogas-based energy could solve both the environmental concern of agricultural waste and reduce dependency of fossil fuels, particularly in Eastern Europe, albeit at a steep production cost.

Regions could use food waste for fuel

Murdoch University researchers are touting biogas from small-scale food waste digesters as a source of renewable energy for rural and regional communities.
