Zardo said that while synthetic zeolites are very, very good at what they do, they are quite expensive. Detergent grade zeolites use low-cost inputs, so the value is lower – between $500-700/tonne. But the company produces the high-grade zeolite type A which costs between $2,500-4000/tonne and represents around 60-70% of the zeolite market.
