Transitioning to Safer Chemicals in Academic Research Laboratories: Lessons Learned at the University of Washington

Abstract

Chemicals are an integral component of laboratory activities in academia but minimizing hazards and environmental impacts of chemicals is challenging. This paper describes how laboratories in University of Washington's Department of Environmental and Occupational Health Sciences (UW DEOHS) partnered with the UW Green Laboratory Program to explore approaches for assisting laboratories to adopt green chemistry principles and select safer chemicals. Chemical inventories, purchasing records, and hazardous waste data were used to quantitate chemical use in DEOHS. Characterizing chemical use based on the data sources provided the project team with a summary of the high volume chemicals used by departmental laboratories. As a way to target chemicals that are highly hazardous but not used in large masses/ volumes, laboratory managers were asked about highly hazardous or toxic chemicals they used. Two chemicals were selected for alternatives assessments and developed into case studies that represent different barriers that laboratories face in their efforts to transition to greener and safer chemicals. This project provided a unique opportunity to survey chemicals used by a set of laboratories with diverse research topics and to assess the practicality of transitioning to safer and greener chemicals in laboratory research using case studies.

Mechanochemistry: New Tools to Navigate the Uncharted Territory of “Impossible” Reactions

“…In a chemical process, solvents are the majority components, often making up over 90 % of the reactant mass [26] . Unfortunately, most organic solvents used in chemical reactions are not environmentally friendly [27] and tend to raise significant concerns for public health and the environment [28] . In addition, their production, transportation, and storage add further issues in terms of economics and safety [29]…”

Specialized Manual on Green and Sustainable Chemistry Education and Learning: Advancing Green and Sustainable Chemistry Education and Learning in All Segments of Society

“…Laboratory program at the University of Washington assisted academic laboratories to adopt green chemistry principles and select safer chemicals. Inventories, purchasing records and hazardous waste data were used to evaluate the sustainability of the lab and to select two target chemicals for alternatives assessments (Krenz et al 2016). Product information, labeling and consumer awareness raising Providing information on the environmental impact of the products that are available for purchase can result in consumers with knowledge and desire to make choices that advance green and sustainable chemistry.…”

Experimental Work in Science Education from Green Chemistry Perspectives: A Systematic Literature Review Using PRISMA

“…In a further 30 reviewed papers, the integration of green chemistry into the curriculum was mentioned, some also in the context of the main benefit of improving chemical safety. In addition, 31 papers addressed a strong synergy between chemical safety and green chemistry goals [27,[78][79][80]. Some papers (n = 27) focus on integrating green chemistry metrics into traditional chemistry teaching [81], while others also compare traditional ex-perimental work to experimental work optimized with green chemistry principles [82][83][84].…”
