Vienna's pioneering team turns trash into clean energy and green fuels

A research team in Vienna is turning waste into clean energy and fuels. Led by Matthias Kuba, the team focuses on producing sustainable alternatives to fossil fuels. Their work includes creating green methane, aviation fuels, and marine shipping fuels from biogenic waste and recycled plastics.

Matthias Kuba, a professor at the University of Natural Resources and Life Sciences (BOKU) in Vienna, also heads the Vienna branch of BEST GmbH in Simmering. His team specialises in thermochemical processes that break down waste into syngas—a key building block for green fuels. Unlike traditional methods that rely on coal, their approach uses biogenic waste and recycled materials.

The team's projects include an EU-funded initiative to boost Austria's green methane production. Currently, biomethane makes up only about 10% of the EU's gas demand, with most supplies going to industry. Fossil natural gas still dominates the market, and large-scale production of synthetic gas from waste remains rare.

Kuba's work extends beyond methane. The team also develops sustainable aviation fuels, marine fuels, and green chemicals. To explain his research, Kuba often uses a Lego analogy, comparing the modular assembly of molecules to building with blocks. Their long-term goal is to replace fossil-based chemicals with green alternatives derived from renewable feedstocks.

The team's efforts could help Austria reduce its reliance on fossil fuels. By converting waste into syngas and green methane, they aim to increase the country's share of sustainable energy. Their research also supports broader EU targets for cleaner industrial processes and lower emissions.
