Plantsea Raises £350k to Advance Seaweed Polymer Production for Biodegradable Films
BIOFUELS
Plantsea has raised £350k through crowdfunding, surpassing its initial £50k target to progress its seaweed-based biodegradable film towards industrial manufacturing trials. The funding will facilitate a 100-fold increase in biopolymer production and allow for demonstration-scale trials in the UK, Europe, and Asia.
The film, designed to match the cost of PVOH in laundry and cleaning capsules, is suitable for conventional manufacturing processes. Plantsea has received over £1.85m in total investment, including from Innovate UK, and is engaged in paid pilots with global brands. The company plans to establish a biorefining plant in Wales.
