Our sustainable solutions portfolio helps our customers to solve complex sustainability challenges, including enabling the use of more recycled content, or biopolymers, sustainable infrastructure, human health & safety, lightweighting, reducing volatile organic compounds, reducing energy usage, and offering eco-conscious solutions. SUPPLIERS AVIENT CUSTOMERS Strategy Avient is actively involved in various associations including the ACC, European MasterBatchers and Compounders (EuMBC), European Plastics Converters (EuPC) and Titanium Dioxide Manufacturers Association (TDMA). Efforts to reduce air emissions—particulate matter, nitrogen oxides (NOx), sulphur oxides (SOx), volatile organic compounds (VOCs) and hazardous air pollutants (HAPs)— are supported by capital investments, integration of cost-effective technologies and innovative operating practices.

We have identified eight ways that we enable our customers to solve complex sustainability challenges and have organized our portfolio accordingly, from enabling the use of more recycled content, formulating with bio-polymers, sustainable infrastructure, human health & safety, lightweighting, reducing volatile organic compounds, reducing energy usage and offering eco-conscious solutions. Efforts to reduce air emissions— particulate matter, nitrogen oxides (NOx), Sulphur oxides (SOx), volatile organic compounds (VOCs) and hazardous air pollutants (HAPs)—are supported by capital investments, integration of cost-effective technologies and innovative operating practices. Dust/mist/fume extraction systems are common, fuel consuming equipment is being retrofitted with high efficiency units, and the use of volatile compounds has been continually reduced.

Avient’s transportation portfolio includes sustainable technologies that offer lightweight structural alternatives to metals, while delivering comparable or improved performance; reduce volatile organic compound (VOC) emissions to improve interior air quality; specialty colors & effects enable paint replacement technologies.
