Aktywat carbon production often involves high- energy pyrolysis (typically 600- 900 ° C) and chemical activation (using fosforic acid, zinc chloride, or potassium hydroxide). These processes generate CO2 and chemical waste. Used carbon, once sativated with trapped activants - including ding blay metals and toxic VOCs - may be classified as hazardouse waste.
