Conditioning of seaweed

Promising preservation method

MacroFuels tested chemical and biological ensiling via lactic acid fermentation processes. Results showed great potential of ensiling as a biomass preservation method for industry-scale operations due to the low energy input required. Processes were optimized during the project, including combining biological and chemical ensiling. All ensiling processes and their combinations could represent cost-effective options for future business operations, especially when combined with novel storage concepts.

Positive side-effects of ensiling

We found out that fermenting sugar kelp by using lactic acid bacteria seems to improve its sensory properties and significantly reduces the tissue content of cadmium and mercury, while sugar and protein contents remain nearly unchanged. This could be of importance for seaweed applications beyond biofuels, such as food and feed.
