MacroCarbon

MacroCarbon is a start-up based in the Canary Islands that specializes in developing Sargassum stationary aquafarming with integrated harvesting and processing. Their goal is to create drop-in feedstocks for the chemical industry such as bionaphtha. Unlike other seaweeds, free-floating Sargassum doesn’t require expensive infrastructure and it can double its mass every 10 days. MacroCarbon aims to develop cost-effective and sustainable methods for growing Sargassum as a biological feedstock for the circular economy.

MacroCarbon’s farms will be integrated with offshore platforms or wind farms. They are working with their partners to develop integrated processing for immediate processing into high-value chemicals.
