About Shell on EarthThey're a small family business run by husband and wife team Jordan & Caryl Andrews. They take the crushed whelk shells generated at their family’s seafood processing factory and recycle them for use in gardens and landscaping. It's estimated that 5000 tonnes of waste shells are generated in the UK fishing industry every year. They are proud to not only reduce our waste output from the factory but also to help support a circular economy by utilising 100% of the whelks they process. This is a natural product from the sea and Shell on Earth does its best to remove any foreign material. All the packaging is recyclable. The white filler is made from vegetable starch and is compostable.
