Sustainable manufacturing using 3D printing and additive manufacturing

We are pursuing advanced technologies such as 3D printing and additive manufacturing, which significantly reduce the scrap and use of scarce raw materials, to produce parts for aerospace and defense applications. For example, advanced manufacturing eliminates hazardous and energy-intensive operations, and it reduces the size and weight of components, thereby reducing aircraft fuel burn. Advanced manufacturing also facilitates on-demand printing, which eliminates the need to ship parts across the globe, reducing our transportation carbon footprint.

Reducing risk in chemical usage

Our integrated Global Chemical Substances program guides our chemical substance compliance and efforts to reduce adverse impacts on human health and the environment, as well as business disruption risk.

Chromates are chemical compounds that help prevent metal corrosion, increase wear resistance and improve adhesive bonding. Despite the benefits, chromates pose environmental and health risks. Complete substitution of chromates is challenging because they need a wide range of substitutes, each of which require extensive evaluation, testing, qualification, customer approval and certification by various global governmental agencies. In 2022, all of our business units made progress in reducing our dependence on this class of chemicals.

Sustainable sites

Collins Aerospace opened new engineering and global operations centers in India to accelerate innovations in R&D and manufacturing. The sites have been designed to the latest standards for sustainable construction; our Global Engineering and Technology Center has been certified with the U.S. Green Building Council Platinum Rating with solar power capabilities and zero water discharge facilities.

We are focused on sustainable design and construction practices as demonstrated in the recent renovation of the 4 Farm Springs building in Farmington, Connecticut, and the recently opened Pratt & Whitney Asheville, North Carolina, factory. The Asheville factory features several sustainability and environmental stewardship initiatives, including LEED certification, zero liquid waste discharge, and 100% achievement of best practices for wastewater, energy and GHGs.
