Waste-to-energy technologies emerge as key drivers for decarbonization

Recent research and technological developments highlight the growing role of waste-to-energy solutions in global decarbonization efforts. An international study identifies biomethane as a mature, cost-effective solution for road transport, particularly for heavy-duty and long-haul freight. Replacing diesel with biomethane can reduce well-to-wheel CO2-equivalent emissions by 45% to 75%.

In the United States, researchers at Lawrence Livermore National Laboratory have developed a 3D-printed, solid-state bioreactor. This device converts methane waste into succinate, a valuable chemical used in polymers and food flavoring, performing over 10 times more efficiently than conventional liquid-state systems.

In Germany, the Fraunhofer Institute for Environmental Energy and Safety Technology has developed a “biobattery” system. This technology uses thermo-catalytic reforming to convert organic waste, such as sewage sludge and food residues, into electricity, heat, purified gas, and biochar.

Furthermore, reports suggest that investing in low-emission transport, building efficiency, and waste management in cities could generate savings valued at US$17 trillion by 2050 while significantly reducing greenhouse gas emissions.
