The Production of Bentonite

Much of our imports consist of 100 % sun-dried clays.
We believe we use a higher proportion of clay that has not been dried with fossil fuels than any of our competitors

MKM has earned a solid reputation as one of the leading suppliers of bentonite, absorbent minerals and cat litter in the UK and Europe since commencing trading in 1989.

We are a compact and versatile company which operates at the level of much larger companies.

The Kentish Minerals division has supplied many high profile projects, starting with Jubilee Line in the 1990s, the Docklands Light Railway,  and the Channel Tunnel Rail Link, which involved supplying high performance bentonite to international Civil Engineering and Tunnelling companies. A recent major contract involved supplying bentonite for sealing low-level Nuclear Waste Repositories.  Our current involvement in Crossrail has entailed delivering bentonite and special grouts within strict delivery constraints in the London Area .

In the Cat Litter business, Macromin Ltd supplies leading supermarkets both direct and through third parties.  Wherever possible, we concentrate on sourcing sun-dried and recycled cat litter products which are eco-friendly.

Additionally both Kentish Minerals and Macromin Ltd supply internationally, with a significant proportion of our business in Russia, a rapidly expanding market.  All our performance products are sourced from quality assured manufacturers. We visit our suppliers regularly to ensure the best commercial terms as well as constant and reliable quality of supplies.
