Waste-Minimization Tips

Tips/suggestions to help minimize the quantity and toxicity of hazardous waste:

  • Order only what is needed. The cost of disposal of chemicals often exceeds the price of purchasing the chemical.
  • Date containers when received and use older chemicals first.
  • Use spirit-filled thermometers instead of mercury thermometers when possible.
  • Use less hazardous or non-hazardous chemicals for experiments when possible.
  • Prepare only the amount of solutions/mixtures needed for experiments.
  • Reduce the number of unknowns by labeling all bottles/containers in lab.
  • Scale down experiments that produce hazardous waste.
