used for infectious waste

Microwave Treatment

used moist heat to inactive pathogens, effective for infectious waste after shredding

like sodium hypochlorite (1:10sol for spills), decontaminating liquid waste before disposal

Biological Process

microorganisms to degrade, mainly for general organic waste

Encapsulation

mixing waste materials then sealing in containers, safe disposal of sharps and broken glass

Inertization

mixing waste with cement to form a table mass, used for pharmaceutical and chemical waste
