Many thanks for the work you have undertaken to remove legionella bacteria from our buildings, the sheer effort required to have achieved this must have been considerable.

Phil. M, Health & Safety Manager, University Client

I am extremely pleased to be able to write to you and commend both teams at Acorn Chemicals Services and MSS Group for all of your hard work and effort helping Tata Steel with reducing chlorides in the waste filtercake that is produced via your operation of the Acid Neutralisation Plant at Llanwern Works. Not only has it facilitated the return valuable materials to the Sinter Plant for re-use, it has also allowed us to realise our ambition of making Llanwern a ‘Zero to Landfill’ site.
