2021 Owens Corning Sustainability Report | Our Approach | Total Productive Maintenance | 82 GOING FORWARD Total Productive Maintenance is an essential component on our March to Zero, and we are greatly encouraged by the results we have seen at our sites around the world. Because its principles foster an environment of empowerment among our employees, we have found that TPM can have applications extending beyond its original intent. This includes ways in which we can reduce our environmental footprint. For example, TPM is helping us develop processes for using production waste in the manufacturing of our composite materials, which will help us divert more waste from landfills and place us closer to our 2030 goals. TPM has strengthened our approach to safety throughout the company. We have assigned a senior EHS leader to each enterprise-wide TPM pillar team, ensuring that safety is an integral part of our approach to each pillar. More information about the role TPM plays in our approach to safety can be found in the Living Safely chapter of this report. Owens Corning has also been employing the principles of TPM to support our healthy living initiatives. Sites are using TPM to build strategies and determine opportunities to make gains in employee engagement around health and wellness. We are also helping employees make the connection between healthy living and TPM as they compare health to safety, injuries, and first aid incidents. Related to TPM, we have been using the 5S framework to help prevent the spread of COVID-19 at our sites around the world. To learn more, please see the Healthy Living chapter of this report.
