Access to water is one of the most fundamental human rights. However, our growing world population has increased demand for water. As water is necessary for Darling’s work producing food, feed and fuel ingredients, great care has been taken to handle and sanitize water properly.

Reducing and Reusing

Darling’s innovation reduces the amount of groundwater used and increased water re-use during our production cycles. In many instances, these innovations that enable the use of recycled water within our processing systems can make Darling facilities net water generators.



Being responsible with water is important to us at the plants. I’m proud that Darling produces more water than it uses.

According to the UN:

By managing our water sustainably, we are also able to better manage our production of food and energy and contribute to decent work and economic growth. Moreover, we can preserve our water ecosystems, their biodiversity, and take action on climate change.

Measuring to Move Forward

Without data we would not be able to optimize on a continuous basis. Darling starts its efforts by measuring key performance indicators like water usage, flow and other metrics throughout the production cycles. We try to generate as much valuable insights as possible from this data, enabling us to act upon it. Darling’s Sustainability Committee has established targets to reduce water intensity of our Collagen/Gelatin and Rendering & Specialties business lines by 5% by 2025.

Data for ongoing progress

  • Water contribution from processing raw materials was 1,611 (MGal) or 6,098 (1000m3). 1,539 (MGal) or 5,827 (1000m3) was from the Rendering & Specialties business line, & 72 (MGal) or 271 (1000m3) was from the Collagen/Gelatin business line. 
  • The total water discharged was 11,000 (MGal) or 41,636 (1000m3), which 3,494 (MGal) or 13,227 (1000m3) was from the Rendering & Specialties business line, & 7,435 (MGal) or 28,145 (1000m3) was from the Collagen/Gelatin business line. 
  • Total water withdrawal from all sources was 9,389 (MGal) or 35,541 (1000m3), which 1,380 (MGal) or 5,226 (1000m3) was from water purchased from third parties, 3,962 (MGal) or 14,996 (1000m3) was from fresh surface water and 4,047 (MGal) or 15,319 (1000m3) was from ground water.
