FlexSea is a British biotech startup that develops seaweed-derived bioplastic. FlexSea’s bioplastic materials derived from seaweed are completely biodegradable in marine and soil environments and are also home-compostable within eight to 12 weeks. The use of seaweed allows a fast material turnover and efficient and sustainable raw material transformation. FlexSea claims that its thorough formulation allows it to produce materials cost-effectively when compared to other bio-based or biodegradable plastics.
The company notes that a seaweed plant can achieve a growth rate of up to one meter per day, sustaining its growth throughout the year. As such, a complete cultivation cycle for FlexSea only requires approximately 45 days, whereas using ingredients like sugar cane would take more than a year, while corn and beetroot demand many months.
The company's products are meant to be used in both dry food and non-food applications and offer a sustainable alternative to traditional plastics. As of October 2023, the company has yet to commercialize its products. The company is looking to initially commercialize its products in the UK and Portugal.
