REMANUFACTURING REMANUFACTURING ACROSS OUR BRANDS Caterpillar machines and components are built to last. They are designed to withstand heavy-duty operating conditions and to be restored and used for multiple lifecycles. Designing products and components to be used throughout multiple service lifecycles is the essence of our remanufacturing approach, which takes many different forms across our brands. CAT REMAN The Cat Reman process returns component products at the end of their initial serviceable lives to like-new condition. Engineers use design guidelines to build key products with remanufacturing in mind, ensuring they are highly durable, even under heavy-use conditions. When a component reaches the end of its initial serviceable life, dealers can return the used component, referred to as core, to Caterpillar, where it is cleaned, inspected, salvaged and remanufactured to original factory specifications, including any relevant engineering updates. Cat Reman uses state-of-the-art salvage techniques, strict reuse guidelines, and advanced remanufacturing processes and quality controls to ensure remanufactured products provide like-new performance, coupled with a same-as-new warranty. We charge a deposit along with the purchase of each Cat Reman product, which gives customers an incentive to return their used components so that we can continue to give materials new life. 36CATERPILLAR 2021 SUSTAINABILITY REPORT
