In Arizona, the bioscience and healthcare industry had an annual earnings of $21.4 billion, employed over 320,000 people in 2015 and more than $383 million went to academic research and development in 2014. This resource summary is intended to assist the biosciences industry reduce waste at the source through green chemistry practices, reducing chemical use and inventory control.


Green Chemistry

Toxic substances are used and hazardous waste is generated in the bioscience industry. Green chemistry designs chemical products and processes that reduce or eliminate the use of those toxic substances or the generation of hazardous waste.

Several drivers exist for changing products through green chemistry, such factors include:

  • Designing safer chemicals and products
  • Increasing producer responsibility
  • Diminishing supplies of nonrenewable resources
  • Increasing costs of storage and disposal of raw materials and hazardous waste

Finding sustainable alternatives to chemicals and incorporating green chemistry are ways the industry can curb the amount of toxic substances used and hazardous waste generated. The benefits of green chemistry include reduced impact to human health, the environment and the economy. Such benefits include cleaner air and water, safer consumer products, less chemical disruption of ecosystems and improved competitiveness of chemical manufacturers. Many resources exist to assist the biosciences industry in embracing green chemistry:

  • See the American Chemical Society’s (ACS's) page to find educational resources for green chemistry and engineering | Go to Page >
  • EPA’s Green Chemistry page provides information on funding for green chemistry, the Green Chemistry Challenge, resources and tools | Go to Page >

Greening Your Laboratories

Applying sustainability techniques to laboratories helps to reduce waste of materials and create a healthier environment for workers. Various ways in which a lab can be greened include recovering solvent used, purchasing alternatives for cleaners and detergents that are any of the following: phosphatefree, biodegradable, chlorine-free, noncorrosive or natural surfactants. EPA Safer Choice has many options for chemical alternatives including medical instrument cleaners | Learn More >

Do you use an Ultra-Low Temperature (ULT) freezer in your lab? If so, reducing the freezer temperature from -80 degrees Celcius to -70 degrees Celsius (- 94 degrees Fahrenheit) can increase the lifespan, save on equipment costs and reduce its energy consumption by 42 percent.⁷Additionally, when you conduct a freezer cleanout and remove frost buildup, you reduce energy use while disposing of old materials, freeing up space and ensuring the freezer is clean and working efficiently. If a new freezer is required, visit the Energy Star website for information on selecting energy efficient freezers | Learn More >

Shut the Sash! Fume hoods can also consume a lot of energy when not shut or closed. Significant energy savings can be achieved just by ensuring that fume hoods are closed when they are not in use. Ways in which you can remind people to shut the sash are to use visual cues such as labels, stickers, or magnets; develop a poster or infographic and appoint a person to ensure the sash is closed when not in use | Learn More >

Reducing Dichloromethane Use

The Toxics Release Inventory (TRI) program collects information on toxic substances used and reported by facilities. Since 2003, Dichloromethane total releases have decreased by 58 percent. Companies are reducing the use of dichloromethane by either finding alternatives or reusing the waste material for other purposes | Learn More >

Read about the following case studies to learn more:

  1. An organic chemical manufacturer that previously used dichloromethane to clean equipment when changing from one process to another, switched from dichloromethane to a less hazardous cleaning solution of water and limonene | Learn More >
  2. A pharmaceutical facility reused gas chromatography solvents recovered in first pass distillation back into the column when clean (and permitted by clients), instead of discarding them and using virgin solvents | Learn More >
