AUSTIN CHALK INDUSTRIES has been in the field of industrial chemicals for more than 150 years. Initially producing ceramics, coatings, fertilizers & lime based products, including some for industrial waste control and odour control in long drop toilets.

With the advent of holding tanks and cassette toilets on boats & motorhomes 20 years ago, we felt the need for a better product than was currently available. The result of considerable research led us to develop CATAZYME-C which stabilizes breakdown, preventing odour development. Discharge of your holding tank to a sewage system dilutes & destabilizes our product, allowing normal biodegradation to proceed.

New clients never fail to mention the absence of ANY odour. Often remarking, “not one smell to cover another”.

CATAZYME-C is used extensively in boats, motorhomes & caravans. It has been a favourite of thousands over the past 20 years. We have a number of clients based overseas, including France, England & Australia, all of whom have tried our product in New Zealand, and continue to purchase regularly.
