Disposal of non-contaminated waste leads to CO2 emissions due to the need for high-temperature incineration. The carbon footprint of disposal of biohazardous clinical waste via high temperature incineration is 1074 kg CO2e/ton compared to regular waste (172–249 kg CO2e/ton) and recycling (21–65 kg CO2e). Various studies have shown that non-contaminated waste generated in the operating room during a primary joint replacement is on average between 5.2 kg and 6.2 kg. Thus, implementing correct waste segregation practices of non-contaminated materials, will aid in reducing the overall impact of emissions on the environment.
