Calcium carbonate and silicon dioxide paper belts are dangerous wastes?
The only thing to note is that if there is calcium carbonate, silica powder bag, the best water wash then, or when wearing a mask or a lot of dust into the lungs can cause pneumoconiosis (and not components, dust inhaled into the lungs is the same problem)
Calcium carbonate and silicon dioxide are non-toxic. So the bags that come into contact with them do not belong to hazardous wastes.
