Promising results from the AQUACOMBINE researchers

Two and a half year ago AQACOMBINE has been set out to find answers on one of the most important challenges of the 21st century.: How to meet the world’s demand for sustainably produced biomass for both food and the growing bio-products sector.

Therefore, AQUACOMBINE aim to create a new circular industry with co-production of food, feed, bio compounds, and bioenergy from salt-tolerant plants such as Salicornia or Crithmum with very little or no production of waste streams within the 4 years project time.

The approach of AQUACOMBINE´s is to combines aquaculture, farming, and bioprocessing to utilize all fractions of the produced biomass.

The last two and a half years were full of research, development, discussions, rethink, and further development. Now it is time to share the promising results of the studies.
