Its use is practical only in warm climates where the evaporation rate exceeds the precipitation rate, either annually or for extended periods, and ideally, where there are steady prevailing

Carbon regeneration – the sustainable way

Our process is simple and we keep from over-oxidising exothermic reactions in the kiln. Overheating the carbon softens the matrix, leading to vastly increased carbon attrition, and quickly ages the pore structure so the useful load-strip-regenerate cycles are decreased.
