By changing your laboratory purchasing practices and choosing greener product alternatives, you can reduce greenhouse gas emissions, solid and hazardous waste generation, and energy and water consumption. The practice of Green chemistry includes the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances and applies across the life cycle of a chemical product, including its design, manufacture, use, and ultimate disposal. Here, we try to address the scope of purchasing required for laboratories. For a technology to be considered Green Chemistry, it must accomplish three things:
- It must be more environmentally benign than existing alternatives.
- It must be more economically viable than existing alternatives.
- It must be functionally equivalent to or outperform existing alternatives. Source: EPA.gov and Warner Babcock
- Opportunity for growth & competitive advantage
- Higher yields for chemical reactions, consuming smaller amounts of fieldstocks to obtain same reaction
- Fewer synthetic steps, often allowing faster manufacturing of product
- Reduced waste, eliminating costly remediation, hazardous waste disposal, and end of pipe treatments
- Less chemical disruption of ecosystems
- Less use of landfills, especially hazardous waste landfills
Tools and Resources
Tools are provided to help you match resources to your laboratory needs. Resources below will help to facilitate:
- Purchasing nontoxic & biodegradable products whenever possible
- Finding substitutions for less hazardous & safer alternatives
- Implementing processes and procedures to reduce use of toxics
- Purchasing Energy Star-rated products when possible
- Identification, removal, & discontinuance of products containing PVCs, BPA, PBTs, or phthalate whenever possible
- Becoming familiar with the principles of green chemistry

The overall goal of the Michigan Green Chemistry Clearinghouse is to accelerate green chemistry awareness, innovation and investment in the State of Michigan by creating and enabling a community of green chemistry advocates that are connected and informed. The Clearinghouse aims to be a dynamic and interactive on-line source of information, resources, databases, learning opportunities and interactive tools for citizens, business and industry professionals, educators, policy makers, entrepreneurs and others.

Management of Chemicals
The document organizes the discussion of managing laboratory chemicals into six main topics: reducing and eliminating the use and generation of hazardous substances (green chemistry); acquisition; inventory and tracking; storage in stockrooms and laboratories; recycling of chemicals and laboratory materials; and transfer, transport, and shipment of chemicals.
The journal says that it “publishes original and significant cutting-edge research that is likely to be of wide general appeal.”
Principles of Green Chemistry
- Prevent waste
- Maximize atom economy
- Design less hazardous chemical syntheses
- Design safer chemicals and products
- Use safer solvents and reaction conditions
- Increase energy efficiency
- Use renewable feedstocks
- Avoid chemical derivatives
- Use catalysts, not stoichiometric reagents
- Design chemicals and products to degrade after use
- Analyze in real time to prevent pollution
- Minimize the potential for accidents
Best Practices in Green Purchasing
- Consolidate orders to reduce deliveries, which reduces fossil fuel emissions, lowers packaging waste, and saves paper, energy, and time.
- Purchase multiple-item packs instead of singles, which reduces waste from packaging materials.
- Increase item lines per order, which saves paper, energy and reduces multiple shipments (and the associated transportation emissions).
- Purchase as many lab supplies as possible from one source, which reduces extra shipping, transportation and packaging.
- Order online to save paper & time,
- Purchase energy-efficient equipment during lab renovations or when older pieces of equipment stop working. Look for the ENERGY STAR ® label
- Ask vendor for energy usage information

The ACS GCI, with financial support from the U.S. Environmental Protection Agency, worked with business schools to produce a series of case studies that can be used to investigate important questions facing businesses as they work to implement sustainable solutions. Innovative approaches to product design, formulation, and manufacturing processes save companies money while helping them align with their sustainability and safety goals (American Chemistry Society).
- Archer Daniels Midland Company
- ADM’s Archer RCTM is now considered a revolutionary innovation in substantially reducing volatile organic compounds (VOCs) from coating products. In addition to the product’s environmental benefits, recent tests have indicated that it is superior to traditional paints and stains.
- DuPont Cleaning Products Division
- pondering the future direction of the division in light of growing concern over the environmental and social implications of the chemical ingredients of cleaning products.
- developed expertise in life sciences, produced biomedical products and agricultural chemicals, and integrated chemistry and biotechnology. DuPont’s culture revolves around safety, business ethics, and respect for people
- Natureworks: Green Chemistry’s Contribution to Biotechnology Innovation, Commercialization, and Strategic Planning
- prestigious Presidential Green Chemistry Challenge Award from the U.S. Environmental Protection Agency for its development of the first synthetic polymer class to be produced from renewable resources—specifically, from corn grown in the American Midwest
- The product was biomass material and held the potential to substitute a renewable feedstock (raw material) for petroleum-based polymers.
- In addition to replacing petroleum as the material feedstock, PLA resins have the added benefit of being compostable (safely biodegraded) or even infinitely recyclable
