Biomedical waste management begins the same way for both physical states — segregation at the point of generation into recognized categories (human anatomical waste, animal waste, microbiology and biotechnology waste, human blood and body-fluid waste, and sharps) using colour-coded, leak-proof or puncture-resistant containers — but the treatment and disposal pathway diverges once the physical form is known.
Solid biomedical waste (soiled dressings, cultures, animal carcasses, anatomical material, sharps) is collected in dedicated bags or rigid containers, held in secure on-site storage, and then treated by autoclaving (steam sterilization), chemical disinfection, or high-temperature incineration before disposal to an approved landfill (post-treatment) or as ash from incineration. Sharps specifically require rigid, puncture-resistant containers regardless of the downstream treatment chosen.
Liquid biomedical waste (blood, body fluids, liquid laboratory cultures) is disinfected — typically by chemical disinfection (e.g. sodium hypochlorite) or thermal treatment — and then discharged to the sanitary sewer under an approved discharge permit, since sanitary sewers and municipal treatment plants are designed to handle disinfected biological liquids but not untreated ones. Where volumes are small, liquids are sometimes solidified with an absorbent and managed through the solid-waste pathway instead.
Common requirements across both streams include a manifest/chain-of-custody tracking system from generation to final disposal, staff training in segregation and spill response, and compliance with provincial regulation (e.g. BC's Health Act and Environmental Management Act) informed by the national CCME biomedical waste guideline.
