In our publication, Reducing laboratory biohazardous waste generation through waste receptacle intervention, we discuss the efficacy of various biohazardous waste reduction methods. 

"Research laboratories generate millions of tons of biohazardous waste annually. Academic biohazardous waste is handled through third-party vendor, typically requiring out-of-state transport and energy-intensive decontamination. These processes are costly to the environment and the institution. We hypothesized much of the waste being handled as biohazardous was uncontaminated, yet placed into the biohazardous waste stream out of convenience and ...."
