Demonstrating more efficient enzyme production to increase biogas yields

Term

August 1st, 2016 – July 31st, 2019

Project

The transition from an economy based on fossil resources to a bio-based economy is a must and should be realized sooner than anticipated at the moment. A drastic reduction in greenhouse gas emission is urgently needed as the goals set to limit global climate change are not being met. The conversion of biomass into energy sources (biofuels, biogas) and chemicals plays an essential role in this transition.

To efficiently convert biomass and agricultural, industrial and municipal waste into fermentable sugars, chemical building blocks or bio-based materials, enzymes play an indispensable role. However, currently available enzymes have not specifically been developed for biogas production and are evaluated by “trial and error”. Thus far, the use of enzymes has not lived up to the expectations as little or no effects could be observed. Hence, efficient enzyme-enabled biomass conversion requires the availability of enzymes that have proven to be effective in practice and can be produced at an industrial scale.

Genencor International BV has recently developed a new enzyme product , derived from Myceliophthora thermophila C1, that in recent field trials has shown a promising 10% cost-reduction in the production of biogas from organic waste. Although the efficacy of the enzyme has clearly been shown, the current fermentation process does not provide sufficient yield in industrial production to be cost-effective for large-scale application.

The objective of DEMETER is to increase the yield of this industrial fermentation process by at least 20%, improve the product recovery process by 40%, and reduce overall product cost by at least 15% while increasing the productivity of the process. In addition, DEMETER will demonstrate the efficacy of the enzyme in 8 field trials in biogas plants throughout Europe.
