Vienna's Scientists Transform Trash Into Fuel and Plastics Without Fossil Fuels

A research team in Vienna is turning waste into useful products like fuels and plastics. Led by Matthias Kuba, the group uses thermochemical methods to break down materials into their basic parts. Their work could help reduce reliance on fossil fuels and imported gas.

Matthias Kuba, a professor at BOKU Vienna and researcher at BEST GmbH, leads the project. His team transforms biogenic waste and recycled plastic into syngas—a mix of hydrogen and carbon monoxide. Unlike traditional methods that rely on coal, their approach uses gasification to decompose complex molecules into simpler components.

Kuba compares the process to dismantling Lego bricks and rebuilding them into new structures. The syngas can then be converted into fuels, plastics, or even substitutes for natural gas. One focus is increasing Austria's share of green methane, which remains low.

The team is also working on green fuels for agriculture. In partnership with ABL Austria, they are running a demonstration project. Additionally, an EU-funded initiative aims to develop synthetic natural gas as an alternative to imports from Russia and the U.S.

A recent experiment involved recycling old car interiors. The goal is to extract green chemicals from sustainable materials, reducing waste and fossil fuel dependence.

The research offers a way to turn waste into valuable resources. By producing syngas from biogenic and plastic waste, the team hopes to cut emissions and boost energy independence. Their work could also support agriculture and reduce Austria's need for imported gas.
