Redesign/Replace - implement material substitution and process changes 2. Reduce - eliminate waste at its source 3. Reuse - find new uses for old chemicals and share what you no longer need 4. Recycle - convert used items back into raw materials, which can be reused. Rethink & Replace Implement material substitution and process changes! • Operational improvements o Input changes o Process changes • Design for energy efficiency • Design for water conservation • Consider the waste produced when purchasing new equipment Reduce Minimize the quantity and toxicity of your waste! • Substitute with non-toxic chemicals • Reduce the scale of laboratory processes • Control chemical inventories • Take care to minimize spills Reuse Find new uses for old chemicals and share what you no longer need! Chemical exchange Recycle Convert used items back into raw materials, which can be reused! • Solvents (acetone, methanol) • Silver recovery from photographic waste • Oil waste • Paint • Batteries • Lab plastic • Lab Styrofoam Hazardous Waste • Main environmental impact of research • Hazardous waste = any product, substance, or organism that is dangerous to the environment or to human beings, and that is no longer used for its original purpose, at the time of disposal, or in storage/transportation prior to treatment or disposal. • Hazardous waste is dangerous because of its quantity, concentration, physical, chemical, or infectious characteristics. Waste Streams at UBC Segregation into two waste streams: 1. Non-Hazardous Waste • Waste Management • Building Operations 2.

Chemicals Minimization Measures • Manage/control inventories • Substitute with less hazardous chemicals − MIT Green Wizard − EPA Green Chemistry • In-lab treatment (corrosives, ethidium bromide) • Reuse chemicals via the Chemical Exchange Program • Solvent recycling (methanol, acetone) Waste Contaminated with Ethidium Bromide • Segregate contaminated, non-regulated solid waste from toxic waste • Deactivate liquid waste before drain disposal • Replace ethidium bromide with: GelRed®, SYBRSafe®, SYBRGreen® Inventory Control • Use free surplus chemicals • Keep an up-to-date inventory of lab chemicals, including location (mandatory WHMIS/WorkSafeBC requirement) • Rotate stock: follow the FIFO principle • Keep track of expiration dates + storage times (peroxideforming, degradable chemicals) • Purchase only chemicals + amounts you need • Accept only gifts or samples you plan to use in the near future • Borrow small amounts from other labs • Purchase smaller containers: large containers often become waste • Keep Material Safety Datasheets (MSDS) and disposal procedures for chemicals used and produced in your lab In-Lab Treatment Options • Consider ALL environmental consequences of YOUR lab activities • Adjust experimental designs to minimize type and quantity of hazardous waste • Replace with less hazardous materials (e.g. non-mercury thermometers) • Use hazardous materials sparingly • Monitor experimental reactions, add chemicals only as necessary • Include experimental steps that destroy or inactivate any hazardous products • Scale down the volume of experiments Reduce Your Solvent Waste Stream Minimize health and environmental impacts: • • • • Avoid and reduce use of solvents Substitute with less hazardous solvents Use “green” solvents – Solvents from renewable resources (e.g. ethanol, or ethyl lactate) – Ionic liquids (salts that are fluid at RT, e.g. ethyl ammonium nitrate) – Solvent-less reactions (e.g. solid state or reagents serve as solvents) – Water-based solvents Send solvents for recycling Ideal Solvent Qualities • Minimal health and safety hazard: o low toxicity o low flammability and volatility o low peroxide formation o lower vapour pressure, higher boiling point • Minimal environmental impact: o increased biodegradability o reduced ozone depletion potential o reduced toxicity o less air emission • Reactivity that fits the reaction • Phase control ability (easy precipitation/separation of product) • Safe degradation or evaporation after use Photographic Waste Fixer and Developer Solutions Photographic waste is treated onsite at ESF: • Ion exchange of fixer for silver removal (~$1000 back per year) • Neutralization • Drain disposal To minimize waste: whenever practical, use digital photography Waste Oil • Send for recycling • Do NOT contaminate waste oil with water, solvents or PCBs • Types of waste oil include: o Automotive lubricating oil o Cutting oil o Fuel oil o Gear oil o Hydraulic oil o Synthetic oil o Emulsion o Vacuum-pump oil (add traps between experiment and vacuum pump) Spills of Hazardous Materials • Use secondary containment for chemical transportation, use and storage • Get spill response training • Ensure proper equipment and materials are available in your spill kit • Identify drain locations and use drain covers • Immediately report all spills to: – Risk
