28 Jul 2022 --- Unilever’s biggest laundry brand, Dirt Is Good (comprising Persil, Skip and OMO), has introduced a newly designed detergent capsule deemed the company’s “most sustainable laundry capsule yet.” The new capsules are packaged in a plastic-free, cardboard container, a move set to prevent over 6,000 metric tons of plastic entering the waste stream every year, the equivalent in weight to 500 double-decker buses.
