Frequently Asked Questions

What is green chemistry?
Green chemistry focuses on either creating chemicals and materials that are safer for people and the environment, or redesigning processes to eliminate the need for hazardous chemicals altogether. Learn more about green chemistry.

What is safer chemistry?
Safer chemistry is a commitment to using the safest possible chemicals in a product or process. A chemical hazards assessment can determine if the chemicals your company uses are toxic.

How can I find safer alternatives for the chemicals my business uses?
Ecology staff may be able to help your business or organization conduct an alternatives assessment to evaluate the safety of your current chemicals and find potential alternatives. Contact Saskia van Bergen at 360-407-6609 to learn more.

What is a regrettable substitution?
A regrettable substitution means replacement of a toxic chemical with one that has unknown—if not greater—toxic effects. One example of a regrettable substitute is bisphenol S (BPS), which quickly replaced bisphenol A (BPA) in many plastic bottles and food. Scientific studies suggest that BPS behaves similar to BPA, so the replacement doesn't necessarily make the product safer.
