Renewi takes next step in the conversion of organic household waste into bioplastics

International waste-to-product company Renewi plc (LSE: RWI) has started converting organic household waste into bioplastics through its specialist organic waste subsidiary, Orgaworld.

The aldermen of the Flevoland province joined Renewi to jointly open the bioplastics pilot

At its Lelystad site in the Netherlands, Orgaworld has developed a pilot scale hydrolysis bioreactor which enables the in-house production of bioplastics from organic household waste. Bioplastics are much more environmentally friendly than other plastics due to their biodegradable nature and use of less fossil fuels in production.

The bioreactor can directly produce the required fatty acids from the organic waste flows currently being processed at the site. During the process the organic waste is continuously sprayed with hot percolate, resulting in high bacteria concentrations. Those bacteria digest the organic waste into sugars, amino acids, fats and other microorganisms that subsequently ferment to produce the desired fatty acids. In the final stage, other types of bacteria convert the produced fatty acids into PHA, a fully biodegradable plastic.

The process will be closed-loop as the bioplastics produced will be reused in the production of, for instance, recyclable bin bags for collecting kitchen and green waste. Eventually, these products will return back to Orgaworld, closing the circle. Orgaworld expects another 3 to 5 years for further development of the process to full commercial scale.

Bas Blom, Managing Director for Renewi’s Monostream Division said:

"We are delighted with our new closed-loop process to turn organic household waste into bioplastics, showing how we are using innovation to fulfil our ‘waste no more’ goal! It is also completely in line with our strategy to create growth with projects using innovation as a competitive advantage."

The bioreactor was jointly opened by Orgaworld, the relevant aldermen of the municipalities in the province of Flevoland and partners Paques and Delft University of Technology.
