Somater partners with Eranova to create algae-based polymer packaging

Somater has joined forces with French start-up Eranova to create a 100% bio-based line of packaging solutions. The partnership aims to provide a sustainable alternative to fossil-based polymers.

Upcycled green algae

Somater’s new range of biosourced solutions is based on the ALGX material developed by Eranova from green algae collected on the banks of a brackish water lagoon near Marseille, in the south of France. Then, the algae undergo a starch enrichment process in large ponds where they continue to draw CO2 from the atmosphere. The starch is then extracted and transformed into processable bio-based resin.

This technology has the advantage of using an invasive natural resource that does not compete with agrarian crops. Furthermore more, green algae can absorb up to 10 times more CO2 per hectare than forests: enough to guarantee an exceptional environmental footprint!

Recyclable composite resin

To create its primary packs, Somater uses an innovative combination of the ALGX biosourced material with PP/PE, thus resulting in a recyclable solution.

“100% bio-based combinations or those incorporating PCR (Post-Consumer Recycled) are also offered. These formulations provide brands with a wide range of options, the positive environmental impact of which is well-documented through standardized Life Cycle Assessments,” said Somater in a statement.

The resin is claimed to be applicable across various manufacturing processes, including injection moulding, extrusion blow moulding, and thermoforming.

Aesthetic qualities

According to Somater, the use of ALGX material gives the product a velvety and silky texture, offering a luxurious tactile experience. The compound with natural "toffee" tones can be available in a palette ranging from white to black, including pastel colours.

Screen printing and hot stamping decoration options can add an extra touch of elegance.

Different packaging formats were presented during the Paris Packaging Week in January 2024, including jars, bottles, caps, closures, and cups.
