Circla is a British e-tailer/circular marketplace. Stocking brands with refillable/sustainable packaging.
They currently offer brands in skincare, makeup, haircare, oral care, period care, household and more.
The way their system is works is when orders are placed, consumers receive a bag. Once products are used up, the consumer arranges for a pickup, the packaging is returned to the manufacturer where they are cleaned and filled again.
It is similar to a milk-man model. Where it gets a little hairy is whether the companies are able to fully reuse the packaging, and the transparency on that end.
