USDA Report Validates that Water Circularity Strategies Can Result in Greater than 90% Water Savings

Grodan was proud to participate in the first of its kind report that validates the water savings potential in Controlled Environment Agriculture (CEA).

Led by the Resource Innovation Institute (RII), the not-for-profit, public-private partnership, the Controlled Environment Agriculture Energy & Water Benchmarking Report: Establishing Preliminary Benchmarks is a deliverable to USDA’s Natural Resources Conservation Service (NRCS) under the Conservation Innovation Grant-funded project titled, Data-Driven Market Transformation for Efficient Controlled Environment Agriculture (CEA). You can download the report here.

The results of this thorough benchmarking:
  • Validates the water savings and water quality potential of CEA, where it has been shown that water circularity strategies can result in greater than 90% water savings compared to common field farming benchmarks.
  • Outlines that, unlike field farms, CEA facilities include processing, packing and storage steps, each requiring energy consumption.
  • Determines that there is no “typical” CEA facility, and therefore determines a range of efficiency performance across differing facility sizes, production methods and business models.
  • Demonstrates that CEA facilities improve their energy productivity and efficiency year over year as growers refine their operations, particularly with support from utilities and governments.
Grodan is excited that our customers participated in this important report, and looks forward to continuing to support efforts of nonprofit and government work examining potential benefits of CEA.

Using less water when growing hydroponically

Water scarcity is one of the global challenges. The problem of water scarcity is a growing one. Water use has been growing at more than twice the rate of population increase in the last century. Food and agriculture are the largest consumers of water. As more people put ever increasing demands on limited supplies, the cost and effort to build or even maintain access to water will increase.

How soilless growing has an effect on less water pollution

One of the 15 global challenges defined by the Millenium project is ‘clean water’. The UN-water (2010) statement contains the following text: “As a global community, we must refocus our attention on improving and preserving the quality of our water, a challenge that requires bold steps internationally, nationally, and locally. Directing global priorities, funding, and policies to improve water quality can ensure that our water resources can once again become a source of life.
