Spotted: UK-based plastic technology specialist, Symphony Environmental, has teamed up with the French biotech company, Eranova, to create a new “smart plastic” bag using upcycled green algae. The technology aims to not only reduce the environmental impact of fossil fuel-intensive plastic but also present new uses for green algae.

Green algae proliferation is a common environmental nuisance. It accumulates in large quantities on beaches, which can create toxic conditions for humans and wildlife. Symphony Environmental has partnered with Eranova to pioneer a technology that transforms green algae into bio-plastic

Eranova’s process extracts starch from the algae to produce a biodegradable and compostable resin, which is then used to manufacture packaging and other products. The biomass can also be used to produce biofuel, proteins for food and animal feed, as well as by-products for the pharmaceutical and cosmetic industries. By using algae, Eranova is able to produce a fossil-fuel-free bioplastic that does not rely on food crops, making it a win-win for sustainability.

Describing the project, CEO of Symphony Environmental, Michael Laurier said, “We are delighted with our collaboration and distribution agreement with Eranova, announced in September last year. This innovative technology looks very promising, and we are excited to see how it develops.”

Bioplastics are seemingly everywhere at the moment, from scented room dividers to construction materials. Many of these, however, are made from food waste or food crops, which means there is often an additional carbon cost in producing them. The Eranova product, which is made from a renewable source that would otherwise be disposed of, could be a more sustainable option.
