Abstract: To improve throughput of biomedical waste treatment, the present inventors devised an exemplary ozone-based system including a shredder, a roll-off treatment bin with ozone injectors, an ozone source, and a controller. The controller monitors electric current drawn by the shredder as shredded waste enters the ozone-enriched treatment bin. In response to current falling below a predetermined low level, indicating that a batch of waste has been shredded and loaded into the treatment bin, the controller starts a treatment timer. The timer measures elapsed ozone treatment or exposure time. If additional waste is added to the shredder and a subsequent low-current condition is detected, the controller restarts the treatment timer. Expiration of the timer indicates that the waste in the roll-off bin is sterilized and ready for transport to landfills. The exemplary system provides continuous waste processing and promises to boost throughput by 50% over some conventional ozone-based waste-treatment systems.
