Unscentedco's cleaning and zero-waste products will be sent to customers in refillable containers. I think it's circular because the dish soap comes in a plastic bottle that the customers can either reuse or refill with one of their 4 or 10L refill boxes (which comes with a spout for ease of use). And the laundry detergent comes in a bottle that is made from 25% post-consumer recycled plastic (PCR). When the customers run out, they can refill it using a 4L or 10L refill box.
It follows the principle of sustainable product design to improve its durability. It can help remove thousands of plastic bottles from the environment. Plus, switching to their bag-in-a-box refills for Laundry, Hand, and Dish Soap can reduce plastic use by at least 80%. It belongs to "keep looping" model.
