Biorefinery

PHA bioplastics are produced by fermentation. ACRRES, together with FBR (also part of Wageningen University & Research) and industrial partners, looks into which residues can be used as raw material for PHA production. The focus is on fatty acids, and then on acidic waste streams such as sewage sludge and plant material, and on the […]

Steviol glycosides from the stevia plant are used in foods as a calorie-free natural sweetener, and are approximately 300 times sweeter than sugar. Along with Newfoss (process development) and Koers (grower), ACRRES works on sustainable extraction of the sweetener from the plant. Tests have shown that the developed extraction method is very effective, but that […]

The goal of this project is to extract soluble proteins, especially from beetleaf, mainly to be applied in the food industry. This preferable without the green color, but the possibilities for the application of green protein concentrate are considered. There is collaboration with WUR FBR, ABCKroos and Provalor. For more information please contact Maarten Kootstra, […]

This project is developing several biorefinery business cases. Here, the specific advantages can be identified on a small scale with the aim to utilize this knowledge on a broader scale. The project focuses on green leaf refining (beet, stevia), production of PHAs (raw material for plastic substitutes), maize refining, small-scale sugar beet refining, biogas production […]

Digestate contains many nutrients and can be a potential food source for algae. This saves money spent on fertiliser. Initial lab trials (with e.g. beef manure and chicken manure digestate) showed that algae will grow on digestate when added sufficiently diluted. The colour and the organic matter contained in digestate are points that need attention. […]
