What to know about Sustainable Technology

Researchers at Lawrence Livermore National Laboratory have developed a 3D-printed solid-state bioreactor that converts waste methane into succinate. The system uses a scaffold structure to increase bacteria density and efficiency compared to traditional liquid-state bioreactors.

What happened

3D-printed scaffolds help turn waste methane into useful chemical using less power than liquid reactors Swati Mestri Scientific Editor Robert Egan Senior Editor When landfills and wastewater treatment plants create methane as a byproduct, much of it is simply…

Why it matters

But the gas is an energy-rich resource that could be recycled as a fuel, chemical feedstock or bioproduct.

Common ground

Capturing and converting waste methane offers an opportunity to recover energy and create useful products from an otherwise wasted gas stream.
