In addition, the plastic waste problem remains a priority for our world and our industry, as education eff orts on the sustainable and inherent benefits of polymers run in parallel with collaborative work to eliminate plastic waste. That’s why in January of 2019 we were very proud to have joined the Alliance to End Plastic Waste (AEPW) as a founding member. It’s inspiring to see the cross value chain activities taking shape, and I believe we are on an encouraging path to ultimately solve the plastic waste problem.

Examples include: • Barrier technologies that preserve the shelf-life and quality of food, beverages, medicine and other perishable goods through high- performance materials that require less plastic • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation • Breakthrough technologies that minimize wastewater, improve the recyclability of materials and advance a circular economy • Composite solutions to support accelerated growth of 5G / fiber-optic infrastructure investment as the world demands greater and faster connectivity Avient employs approximately 8,400 associates and is certified ACC Responsible Care® and a founding member of the Alliance to End Plastic Waste. Leading in Sustainability — PolyOne and Clariant are both founding members of the Alliance to End Plastic Waste, and we are committed to meeting the needs of the present without compromising the ability of future generations to do the same. Develop and implement solutions to end plastic waste while supporting AEPW $1.5B investment in key initiatives. 2030 SUSTAINABILITY TARGETS 11 FUTURE GROWTH IN EXCESS OF GDP IS DRIVEN BY: Our company is positioned to sustainably grow at a rate that exceeds GDP.
