Using the right design criteria in the fermentation stage, more than 80% of the theoretical yield of ethanol on carbohydrate can be realised. Using the example of kitchen waste generated in the European Union as a feedstock, this process could generate 86% of the bioethanol market in 2019. Also it will generate electricity for approximately 9.3 million European households (5% of the total households). As kitchen waste has a negative value, in urban areas with high waste generation per square km, competitive business cases can arise.
We are testing a new biobased European feedstock with our patented enrichment technology with the aim to yield >70% (g/g) of L-lactic acid on carbohydrate fed.
In parallel we are running a downstream processing base case process to obtain high purity L-lactic acid in water as a 1st platform product. One our purification steps is a carbon treatment to remove organic impurities.
We highly appreciate the financial support of the Dutch Research Council (NWO) through the take off 1 grant – to support our work in this technical feasibility study. Also, we thank Delft University of Technology for facilitating us.
Through the Dutch Research Council (NWO) we have secured a second round of funding for a feasibility study. Using these resources, we will investigate the potential of our ecology-based L-lactate production using different feedstocks. In parallel, we will produce the first 100 mL of concentrated L-lactic acid solution. Also, we will calculate the economic performance of our process using these different feedstocks.
We secured our first funding to perform lab scale research in 2020 in February 2020. This funding was provided by the TTT fund, which aims to support technology trasnfer of universities into commercial applications within the context of creating a circular economy.
