Israeli vegan ‘style’ start-up making clothes using seaweed
The company hopes “to harness the power of renewable algae to create a real and genuine impact against climate change,” she said.
A green solution
Algae, which includes algae, is already used in other industries; The food, pharmaceutical and even biofuels industries all view this group of aquatic organisms as a sustainable material.
Krebs also saw an opportunity to apply algae to textiles. Working in the fashion industry for 15 years, she saw firsthand the pollution and waste of the industry. After quitting her job in 2014, she launched Algaeing in 2016.
The seaweed is supplied by another Israeli company, Algatech, grown in seawater on indoor solar-powered âvertical farmsâ. This means that unlike cotton, it does not occupy agricultural land and does not have the carbon emissions associated with the use of fertilizers.

Algaeing converts the algae into a liquid formula which can then be used as a dye or made into a textile when combined with cellulose, a plant fiber, which clothing manufacturers can make themselves using the proprietary recipe of Algaeing.
Krebs said Algaeing’s goal is to change the supply chain and the company is preparing for the commercial launch of its patented technology in 2022.
Rethinking the fashion industry
“Algaeing and Renana [Krebs] tackle three key issues in the fashion industry: reliance on fresh water to grow fiber; the use of chemicals, both in pesticides for growing fibers and also in dyeing textiles; and third, energy consumption. “

Currently, algae-based fibers are more expensive than conventional fibers like cotton, but Krebs said that as a sustainable and ethical product, it adds value to the brand.
Bang said that over the past five years, awareness of sustainability in fashion has steadily increased, attracting “new types of investors” with diverse backgrounds in technology, science and technology. materials and biochemistry.

Algaeing received the H&M Foundation Global Change Award in 2018, and the company’s work with algae highlights a “bright potential source” for future textile fibers, Bang said.
“Algaeing and Renana [Krebs] tackle three key issues in the fashion industry: reliance on fresh water to grow fiber; the use of chemicals, both in pesticides for growing fibers and also in dyeing textiles; and third, energy consumption, âsaid Bang.
He adds that even as consumer behavior changes, it is still costly for the industry to invest in and develop sustainable technologies. âWe need lawmakers to change the rules of the game, and tilt them much more in favor of circular and sustainable practices, and punish old habits,â Bangs said.
Beyond fashion
While Algaeing initially focused on reinventing fashion fabrics, the pandemic presented another opportunity. In 2020, Algaeing started working with Avgol, a nonwoven fabric manufacturer specializing in hygiene, medical and PPE products.
Krebs said the pandemic has shown businesses and brands that adapting to new challenges is vital for survival. While the recent challenge has been Covid-19, the biggest long-term challenge is climate change – and that’s where Krebs hopes Algaeing can make a difference.
âWe are creating a new generation, a new category of products,â Krebs said.
