4 Start-ups producing and using Algae

The Algae Protein market size exceeded GBP 510 million in 2020 and is estimated to grow at a Compound Annual Growth Rate, CAGR, of over 6% between 2021 and 2027. With an increase of use within Human food, Plastic alternative, Textile and Animal feed markets.

Food markets

Start-up research company Beauhurst has data showing that private UK companies producing or using Algae within the food and drinks sector have risen by around 2000% over the past decade. In 2011, three deals raised £314,200, while in 2018, seven raised £6.4m.

Entrepreneurs and Investors are focusing more and more on algae as an alternative protein source to help feed a growing global population. The UN forecasts it will rise from 7.7bn today to 9.7bn by 2050.

Algae, and in particular spirulina (blue algae), is one of the most nutrient-dense foods on the planet. It has more calcium than milk, more beta-carotene than carrots, more potassium than a banana, and more protein than meat. And as a bonus, it has a lovely blue colour - perfect for brightening up your morning shakes.

Firglas is developing commercial-scale algae facilities in Almeria, Spain and Rotterdam, The Netherlands, to address food-grade markets. With aims to harvest 100 tons of algae per year.
The company has previously developed and advised on microalgae projects with partners worldwide.
They aim for solid financial returns alongside positive environmental and social impact, aligning investments with ethical values and enhancing the risk/return profile.

Traditional petroleum plastics are responsible for pollution in the air, sea and land, which is destroying ecosystems.

Algae is one of the most environmentally friendly replacements to fossil fuels in the creation of plastics. Although other bio-based materials can be non-toxic alternatives to fossil fuels, they are not as eco-friendly. e.g. Sugar cane, which requires the use of arable land and fertilisers.

Algae farming produces high yields and short cultivation times, with the added benefit of using carbon dioxide in the process.

Algenesis, is a material science and technology company on a mission to help the planet recover from the pollution caused by products made from fossil fuels.
Their scientists redesigned plastic materials to harmonise with nature. Their patented Soleic™ technology is the world's first high-performance, renewable, and fully biodegradable plastic material made from plants.

SOLEIC™ BIODEGRADATION - Built to Last...Made to Disappear


The textile industry is the second most polluting industry in the world. 

Even growing natural fibres such as cotton can be damaging. It requires a large amount of water and uses up precious arable land, which could be alternatively used to grow crops for consumption.

Algae is the new renewable resource for making fibres for use in textiles, which can create sustainable degradable fashion.

AlgiKnit, Based in Brooklyn, New York, is creating the next generation of eco-conscious materials from seaweed.

AlgiKnit is creating eco-conscious, renewable yarns for the circular economy. We're developing durable yet rapidly degradable yarns from kelp, one of the most regenerative organisms on the planet. Our material is built for everyone: a functional and accessible resource without environmental harm. We're envisioning a future where the textile industry operates in a closed-loop product lifecycle, utilising materials with a significantly lower footprint than conventional textiles.

Animal Feed

There are many advantages associated with using Algae in animal feed. It's an excellent source of protein, antioxidants, fibre, fatty acids, vitamins, and minerals, that most animals require for their basic body functions.

Fish farmers, as an example, have faced increased costs associated with creating fish meal. So they are increasingly turning to using algae for their high protein fish food.

Inalve, cultivate microalgae and turn it into ingredients for use within animal feed. Feeding animals using a sustainable source of protein.
They cultivate microalgae in a biofilm using only water, sunlight, CO2 and minerals. This patented algae growing process significantly increases productivity, resulting in more efficient use of resources. This results in a highly concentrated biomass that has unique physical and nutritional properties. Once harvested, it is transformed into ingredients for nutrition and health.

We minimise our impact on the environment throughout our production process. A Life Cycle Analysis, LCA, was conducted to validate our production's claim on sustainability and verify its scalability. 

Growing their Microalgae compared to other crops:
• Non-GMO
• No pesticides
• Requires 60 times less land
Compared to existing microalgae production systems:
• 70% less water
• 50% less energy
