01 Aug 2022 --- Unilever’s biggest laundry brand, Dirt Is Good (comprising Persil, Skip and OMO), is unveiling a new biodegradable detergent capsule lauded as its “most sustainable laundry capsule” to date. The capsules come in a plastic-free cardboard box developed by Graphic Packaging International. The cardboard container is set to prevent over 6,000 metric tons of plastic from entering the waste stream every year, the equivalent in weight to 500 double-decker buses.
