Citizens of Soil has released edible packaging for its extra virgin olive oil, made with Notpla’s seaweed-based material. The product is marketed as natural, biodegradable, home-compostable and vegan. Notpla landed £20 million (US$26 million) in a series A+ fundraising round last month, doubling its initial target. The company expects to replace over 100 million single-use plastics annually within the next two years and will use the funding to build an expansion in the US.
