Solution for Intensified Offshore Cultivation of Macroalgae




With continuous population growth, there is an increased demand for human and animal food, but the arable land available is decreasing every year. Land is losing its ability to grow crops due to desertification, soil salinisation and climate changes. Therefore, the use of terrestrial resources to produce bio-based polymers is limited and does not allow scalability to compete with fossil-fuel plastics’ annual production quantities. Marine macroalgae is a rising source for agriculture alternative in many industries including, human and pet food, healthcare, cosmetics and medical, amongst others. The use of macroalgae is also an attractive source to produce biopolymers. This technology offers a complete solution that enables growing macroalgae offshore. The solution incorporates a device, method and system to intensify the cultivation of macroalgae, allowing a farm to be established offshore, anywhere in the world, lowering feedstock cost. This solution utilises a ubiquitous algae found in every sea and ocean, as well as sea water throughout the process. The farming and harvesting cycles are shortened, thereby allowing easy scaleup and reducing the need for a large number of farms to meet the growing needs of the world. Altogether, the use of marine biomass, no use of fresh/treated water, nor the use of land, provide a scalable solution that can provide the ongoing increased demand for plastic products.


This technology carries the following features: Positive environmental impact Growing Macroalgae has positive environmental effects in terms of CO2 and marine life – it absorbs carbon dioxide and can assist in reviving marine life as the two provide mutual contribution to each other; the algae feeds from the marine life nutrients and other marine life feeds on the algae Smart use of the algae farms can contribute to its surrounding environment (such as fish farming and others) Use of macroalgae as biomass Allows the use of sea water (salted, not treated) in the entire process Biomass that does not compete with nor depends on arable land High yield Harvesting cycles every 2 weeks, all year long Number of marine farms needed is relatively small to provide for the global plastic demand


The targeted applications for this technology are (but not limited to): Growing or farming macroalgae for the production of biopolymers as an attractive source to produce biopolymers as an alternative to terrestrial crops Growing or farming macroalgae as a commodity for various verticals: Alternative proteins Bio-fuel Cosmetics Food and beverage Healthcare


A device, method, and system for intensified macroalgae cultivation offshore, provides the following advantages and benefits:  Can be established anywhere in the world Low energy cost Improved yield per area, potentially by 5 folds The ability to provide enough biomass for large scale production Improved harvesting cycles – short cycles, all year long Minimal variation on biomass growth
