SUSTAINABILiTY
At UDA, sustainability is at the heart of who we are.
Committed to the principles of sustainable development, we emphasize transparent reporting, responsible animal care, and meaningful contributions to the economic and social well-being of our communities.
Family-Farmed. Future-Focused.
Founded and owned by Arizona’s dairy farming families, the original stewards of our land, water, and animals. For generations, our members have prioritized environmental care while producing the highest quality dairy products.
Paloma Dairy
Paloma Dairy and Sunset Farms are owned and operated by the Van Hofwegen family, a fourth-generation dairy farming family in Gila Bend, Arizona. The farm is dedicated to sustainability and animal care, using innovation and technology to achieve best practices.
The Van Hofwegen family also owns Sunoma Renewable Biofuels, a facility that turns manure and other farm waste into clean energy. This process helps the farm reduce waste and reuse valuable resources. To conserve water, they use advanced watering and management systems designed to minimize waste. Beyond their farm, they actively support renewable energy by serving on local energy boards and working with community members to improve energy use and management.
When it comes to animal care, Paloma Dairy uses sophisticated computer systems to monitor the health and wellbeing of their livestock. They also use genetic testing to enhance the health of their animals. By making animal care and sustainability central to their business, Paloma Dairy continues to adopt new innovations that keep them at the forefront of responsible farming.
Triple G Dairy
Triple G Dairy is a multi-generational, family-owned farm committed to excellence in milk quality, sustainability, animal care, and leadership within the dairy industry. Now owned and operated by brothers Ben and K.C. Gingg, the farm’s legacy began in California before relocating to Arizona in the early 1950s. What began as three separate dairies has since evolved into one unified farm in Buckeye.
Triple G Dairy integrates sustainability across all three pillars: environmental, social, and economic impacts. On the farm, Triple G utilizes a methane digester, has strong water recycling efforts, prioritizes animal health through preventive care, and invests in continuous workforce training. These efforts are driven by a long-term vision for environmental stewardship and community impact.
The team at Triple G believes that a culture rooted in responsible animal care and proactive farm management is essential to reducing environmental impact, supporting people, and ensuring the dairy remains resilient for generations to come.

At United Dairymen of Arizona, we are committed to dairy and about doing our part for the planet. We recognize that cows and our operations contribute to greenhouse gas emissions, and we take that responsibility seriously. That is why we have taken steps to reduce our environmental impact across everything we do. Progress has been made, but we know the work does not stop there. We are continuing to explore new technologies, partnerships, and ideas to support long-term sustainability across the entire dairy supply chain.
We are proud of adopters of the U.S. Dairy Stewardship Commitment, a voluntary pledge to demonstrate sustainability progress through industry-aligned action and reporting in the areas of environmental and social sustainability.
