If it’s infectious or potentiall y infectious (to animals or humans) or potentially harmful to the environment (pollens or fungi etc.), we treat liquid biowaste with freshly-prepared 10% bleach solution for a 30 minute contact time and then drain dispose.

For solid biowaste, it really depends on what it is contaminated with to inform you management practices.  If i t falls into the chemical hazardous waste requirements, if it’s animal bits, bloodborne pathogens – that’s a whole other set of issues .

Subject: [DCHAS-L] Handling Biology Cell/DNA Waste

We are a small size liberal arts university with a natural science department that has begun some areas of research which is producing waste solutions which contain cell and DNA components. How is this type of waste being handled by others?  Would it be considered Biohazard or can it be disposed of dow n the sink as non-hazardous waste?
