FlexSea has teamed up with the UK Centre for Process Innovation (CPI) to optimise and up-scale the biosynthesis of two innovative biomaterials. Poly-gamma glutamic acid and Poly(hydroxyalkanoates) are two classes of biologically derived biopolymers that could significantly displace synthetic alternatives. With FlexSea striving to meet the demand for home compostable, bio-based alternative products to conventional plastics, this project aims to tackle this significant industrial challenge.Thanks to FlexSea's innovative fermentation technology we can now use spent algal fractions (by-product of FlexSea's transparent film casting technology - uses 20\_40% of the seaweed fraction) to synthesise these materials reproducibly. During the project we aim to further optimise the yields and characteristics of the biopolymers as well as liaise with industrial partners to assess their properties for a number of applications.During the project the biosynthesis of these materials will be up-scaled from 250 mL to 4-L to 1500L.By the end of the 20-month project FlexSea aims to patent the technology and employ the material synthesised to undertake commercial pilots with several industry partners.In addition, the consortium will deliver a full technoeconomic and life-cycle assessment for further commercialization of the technology. By producing three single use plastic- alternatives (hydrocolloid films; PHAs, PGGA) in a biorefinery approach, we aim to scale and commercialise the sustainable (no waste) and economic advantage (reduced raw material costs; additional revenue stream) of using seaweed as a sustainable bio-based feedstock.

FlexSea 与英国工艺创新中心 (CPI) 合作，优化和扩大两种创新生物材料的生物合成。聚γ谷氨酸和聚羟基脂肪酸酯是两类生物衍生的生物聚合物，可以显着取代合成替代品。 FlexSea 致力于满足对传统塑料的家庭可堆肥、生物基替代产品的需求，该项目旨在应对这一重大工业挑战。得益于 FlexSea 的创新发酵技术，我们现在可以使用废藻类碎片（FlexSea 透明的副产品）薄膜铸造技术 - 使用 20\_40% 的海藻部分）可重复地合成这些材料。在该项目期间，我们的目标是进一步优化生物聚合物的产量和特性，并与工业合作伙伴联络，评估其在多种应用中的性能。在该项目期间，这些材料的生物合成规模将从 250 mL 扩大到 4 -L 至 1500L。在为期 20 个月的项目结束时，FlexSea 旨在获得该技术的专利，并利用合成的材料与多个行业合作伙伴进行商业试点。此外，该联盟将交付全面的技术经济和生命周期评估，以进一步实现该技术的商业化。通过采用生物精炼方法生产三种一次性塑料替代品（水胶体膜、PHAs、PGGA），我们的目标是扩大使用海藻作为原料的可持续（无浪费）和经济优势（降低原材料成本；增加收入来源）并将其商业化。可持续的生物基原料。
