It’s December again and time for another UN Climate Change Conference, COP 25 in Chile. This annual environmental ‘frenzy’ began in 1992 at the Earth Summit in Rio de Janeiro, when 178 member countries of The United Nations Framework Convention on Climate Change (UNFCCC) entered into a treaty to ‘stabilise greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system’.

Trailblazer Technologies’ John Bewsey is pioneering cost effective and potentially profitable ways of processing neutralised acid mine drainage (AMD) water, industrial wastewater and even underground ‘brakwater’. In this article, he describes his KNeW (Potassium Nitrate ex Waste) process, which relies on scalable ion exchange CSTR batteries with some value adding regeneration and post regeneration twists to transform dissolved contaminants into valuable fertilisers and industrial salts.
