Reducing Our Environmental Footprint
As an animal health company, being good stewards of the environment is important to us and our customers. While manufacturing products can be water and resource intensive, we are heavily focused on making our operations more water efficient, identifying opportunities to recycle and repurpose our wastewater, reduce the amount of waste that we produce and responsibly manage our waste.
To reduce our water intake, we have invested in improved technology, such as closed loop cooling systems. We identified opportunities to reduce and reuse water in our processes and implement additional efficiency measures. We integrated lean manufacturing principles and tools to help facilities identify areas for water conservation. This has allowed us to reduce our water intake intensity by 2% in 2021. While water use increased by approximately 380,000 cubic meters, we experienced significant growth in water intensive manufacturing operations in our biologics and fermentation operations. We also increased our water recycling efforts, including the use of reject water from purified water loops as feedwater for boilers.
During 2021, we strengthened our global processes and internal controls for waste management to enable streamlined traceability of all our waste streams. In addition, we improved our onsite waste management processes and increased our capabilities to segregate and recycle waste. This has allowed us to identify innovative opportunities to repurpose our waste. For example, our manufacturing site in Campinas, Brazil partnered with a nearby cement manufacturer to enable ‘Co Process’ recycling of a Zoetis waste solvent stream. Zoetis provided 55 tonnes of waste solvent to the neighboring cement manufacturer for use an ‘alternative fuel’ in the cement manufacture process. In addition, in 2021, we launched an ambitious program of hazardous waste reduction projects at three of our top ten waste generating sites. This program has a goal of reducing our hazardous waste footprint through improved management of aqueous waste streams.
