Cambi and Sasol innovate to move up the waste hierarchy through thermal hydrolysis

Asker, Norway, 21 November 2022

Cambi has signed a large contract with Wood, a global leader in consulting and
engineering, to supply Sasol with two full-scale thermal hydrolysis process
(THP) systems for treating industrial biological sludge at Sasol’s Secunda
Operations (SO) in South Africa.

Sasol and Cambi commenced a commercial trial at SO in 2021 using a small-scale
THP unit. Extensive laboratory tests and integration checks demonstrated the
feasibility of refunneling industrial biological sludge into Sasol’s
coal-to-liquids (CTL) gasification process and identified the optimal process
parameters for full-scale application.

“We are excited about this project, as it will enable us to improve our waste
management by moving up the waste hierarchy while improving ambient air quality.
This will enable Sasol to move away from incineration and, at the same time, to
derive syngas from biosludge. We recognise the link between our activities and
the need to act responsibly by holistically managing the impacts of our
operations through world-class innovation,” said Simon Baloyi, Executive Vice
President for Energy Operations and Technology at Sasol.

“Today’s contract is important for Cambi, marking our first full-scale THP
project for industrial substrates outside of Norway. The project is unique in
the world and introduces a new, sustainable way to process large streams of
biosludge. The swift progress from demonstration to full-scale adoption shows
that THP makes business sense in many settings and is testimony to Sasol’s solid
commitment to reducing carbon emissions. We look forward to seeing the
full-scale solution in operation as soon as possible”, remarked Eirik Fadnes,
CEO at Cambi.

This innovative project will reroute biosludge from incineration to the
gasification process, thereby reducing point source emissions. It will be the
world’s first full-scale installation where thermal hydrolysis is used to enable
the conversion of biosludge into hydrocarbon fuels and chemicals.


The THP equipment supply contract follows an engineering design project carried
out by Cambi earlier this year in close collaboration with Wood, who were
commissioned to deliver the full sludge refunnelling solution.

For Cambi, the project is ready to go into the manufacturing phase. The two THP
systems are scheduled for commissioning in 2024.
