In 2022, we continued to expand the scope of cleaners and degreasers that are safer to use. In 2022, biocompatibility testing beyond individual materials to we approved 58 safer cleaners for use in our supply We evaluate the safety of our products and materials include modules and whole products. Through this work, chain, bringing the total number of safer cleaners we’ve through chemical analyses at our Environmental Testing we have an even more comprehensive view of each approved over the past three years to 133. Each of these Lab. Our chemists test materials to monitor compliance material and the impact that assembly has on safety. cleaners has gone through a rigorous independent with our specifications.

In 2020 and 2021, we received the EPA Safer comprehensive assessments like GreenScreen®, focused considerable attention on the chemistries of Choice Partner of the Year Award for our work to scale the a methodology that we use to gauge the impact of cleaners and degreasers. We’re investing in the due use of safer process chemicals and protect those working chemicals on individual health and the environment diligence required to identify preferred alternatives for use in our supply chain. based on 18 criteria.

We’ve proactively provided our suppliers a list of cleaners and degreasers that are safe to use, and since 2018, all of our final assembly sites have used only safer alternative cleaners and degreasers.
