More about State of the industry report

The industry is working to do more with less. The production of commercial fertilizers requires a significant amount of natural resources, such as natural gas, water, and land. However, TFI member companies have invested billions of dollars in facility upgrades that have made the production process more efficient and sustainable.

Investment in capital improvements, including upgrades to existing production facilities and the construction of new, more efficient facilities, provides opportunities to implement state-of-the-art technologies that capture GHG emissions, achieve zero water discharge, capture waste heat for energy production, and reclaim all mined lands.

The data reported in this report represent a substantially different set of participants than prior years; therefore, representation of trends would not be accurate. As the total number of companies that participate in this report changes, so does the quantity of reported natural resources used. For clarity, this report will focus on normalized numbers or the amount of resources needed to produce one ton of fertilizer.


Sustainable water use is a key element in the industry’s conservation efforts. Water is a significant resource in the production of phosphate and potash fertilizers, and to a lesser extent for nitrogen. TFI gathered water-related data based on volume (in gallons) of water purchased and water withdrawn from wells and surface water.

Water Usage among Nitrogen Producers

Among nitrogen producers, water usage on a per-ton basis has decreased each year since reporting began in 2013. The amount of water used to produce one ton of nitrogen fertilizer is down 7 percent from 2016 to 2017 and down 42 percent since 2013.

Water Usage among Phosphate Producers

Water use on a per-ton basis increased slightly for phosphate producers, as facilities continue to increase efficiencies and reuse water throughout the production process. The amount of water used to produce one ton of phosphate fertilizer in 2017 has increased four percent since 2016.

Many fertilizer manufacturers have set water efficiency and zero-discharge goals for their operations. These goals are achieved through the use of recycled and reclaimed water. Recycled water refers to water demand an organization satisfies by reusing water during the production cycle instead of withdrawing additional water. Reclaimed water is wastewater used from third-party sources that offsets water that would otherwise be drawn from other sources. Members reported recycling 516 billion gallons of water within their operations in 2017. This is the same amount of water that 5,160,000 households use every year.5

Industry HighlightApache Nitrogen Products, Inc.

Apache Nitrogen Products, Inc. (ANPI) operates a zero-discharge facility that reduces environmental impact by limiting water waste. Through these efforts, ANPI avoids additional water consumption and captures up to 10,000 tons of potential waste annually.

ANPI’s manufacturing facility in Benson, Arizona, produces nitric acid and both dry and liquid forms of ammonium nitrate, which supplies both the mining and agriculture industries.

The major feedstock to ANPI’s process is anhydrous ammonia, which is imported to the facility from various locations. The heating and cooling required in the processes are provided through steam and cooling water, with the approximate 650 gallons per minute of water being supplied from deep aquifers. In addition, the nitric acid production process also produces water as a byproduct. To execute on the zero-discharge program, ANPI employs two key methods. The first is the capture of all liquid waste product streams, which are reprocessed in a state-of-the-art, automated facility to provide a clean feedstock for salable products. This system has recently been upgraded using Swiss technology, resulting in a high degree of automation.

The second method involves managing all blowdown streams from cooling towers and boiler systems. These are collected and then reprocessed through a brine concentrator, which provides two streams. The main stream from this process is a high-purity water stream that is used to produce the steam that is used in the ammonium nitrate production process. The second, and much smaller, stream is a slurry of concentrated reject materials that is collected and shipped to a landfill periodically.

In 2017, member companies reported they operated a total of 29 zero-discharge facilities. A zero-discharge facility is defined as having no direct liquid discharge to surface or ground water, other than stormwater drainage. These facilities are beneficial because they avoid adding any pollution load to waterways, except for runoff from precipitation.

Greenhouse Gas Emissions

Minimizing greenhouse gas (GHG) emissions is a priority for companies in the fertilizer industry.

High purity carbon dioxide (CO2) is a byproduct of ammonia production, but it is also a necessary ingredient in the production of urea fertilizer; therefore, the industry captures CO2 emitted during ammonia production and re-uses it during the urea production process. Excess captured CO2 from fertilizer production is also recycled for other industrial use, such as enhanced oil recovery and the carbonization of soft drinks.

In 2017, the industry captured and re-used 7.5 million metric tons – which is 24 percent of all GHGs emitted by the industry throughout the year. While the percentage of CO2 emissions captured is down fractionally from the 2016 number of 25 percent, it represents a dramatic increase over 2013, when the industry captured and re-used 9 percent of its GHGs. The 2017 emissions captured are equivalent to the total annual emissions from one coal-fired plant.6

Anuvia Plant

Industry HighlightAnuvia Plant Nutrients

Anuvia’s innovative technology reclaims organic waste materials, such as food scraps, which are processed into homogenous multi-nutrient, enhanced-efficiency, slow-release plant nutrient products that help protect the environment, improve soil health, and support plant growth. The manufacturing process significantly reduces Anuvia’s carbon footprint by producing four times less CO2 emissions than conventional fertilizers.

The fertilizer technology is based on a novel slow-release delivery system called the Organic MaTRX™, a delivery system that mimics what happens to organic matter in the soil. It returns up to 16 percent organic matter to the soil.

This technology represents an ideal circular economy addressing the three pillars of sustainability. Social: this technology is a new, clean, and efficient way to recycle organic waste, producing a pound of fertilizer from a pound of waste in a closed loop process. Environmental: nutrient loss is reduced, thereby protecting our watersheds. Net greenhouse gas emissions are reduced in the process and in application. Economic: these products contribute to efficient clean food production by putting value back into organic waste materials


The production of fertilizer requires energy, either in the form of natural gas or other fuels, electricity, or steam. As part of their sustainability efforts to reduce their energy footprint, fertilizer manufacturers cogenerate energy or use other low-impact energy sources, such as solar or steam from waste heat.

This report captures energy consumption and intensity. To help illustrate the magnitude of energy consumed and types of energy used in the industry, participating companies provided data for direct and indirect energy use. Direct energy use is either total fossil fuel consumption or a breakdown of the individual fuels used (diesel, propane, fuel oil, natural gas). Indirect energy use is reported as the electricity use generated offsite and purchased steam use.

Participating companies reported using 11.3 gigajoules (GJ) of energy per ton of fertilizer produced.

During the fertilizer production process, heat is generated, captured, and used as thermal energy for heating and electricity generation. In 2017, companies reported capturing 101.8 million GJ of waste heat. This is equivalent to 51 percent of the total energy use reported by all participating producers. From this waste heat, companies were able to generate 2.3 billion kilowatt hours of electricity from the capture and reuse of this waste heat. This is energy that manufacturers would otherwise have to purchase or supply by fuel combustion.

TFI on Policy

Energy Star

Fertilizer production is an energy-intensive operation. TFI partnered with the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR program to develop tools that fertilizer manufacturers, particularly those that produce nitrogen fertilizers from ammonia, may use to improve the energy efficiency of their manufacturing operations. Specifically, to help member companies benchmark their operations, TFI worked with the EPA to develop the ENERGY STAR Plant Energy Performance Indicator (EPI). The EPI is an energy-management tool that enables companies to compare the energy performance of their plant to the performance of plants of peers across the industry. EPIs also help companies measure, track, and benchmark plant energy performance over time and against the industry. Such data are critical to determining potential process changes to further enhance energy efficiency and in setting energy improvement goals.

Land Reclamation

Fertilizer production can have a significant physical footprint, especially in the mining sector. However, surface-mined acres are reclaimed, restoring such lands for productive uses by both wildlife and people. While land-reclamation data are primarily focused on mine reclamation, the information is applicable to any fertilizer producer who has disturbed and/or reclaimed land around their facilities. Land reclamation associated with mining activities is not a steady activity year-to-year, but instead follows the mining cycle. It is not unexpected to see swings in the number of acres reclaimed from year to year as mine sites close or reclaimed acres are released. In 2017, companies reclaimed 2,895 acres of land.

Industry HighlightThe Mosaic Company

In Mosaic’s Florida phosphates operations, teams of biologists, ecologists, and engineers conduct acre-for-acre reclamation, returning mined lands to productive wildlife habitats and recreational, agricultural, commercial, or residential purposes. Here are some of the many ways Mosaic returns formerly mined land to productive use for wildlife and people:

  • Mosaic’s reclamation techniques create high-quality habitats ranging from prairies and forests to wetlands and lakes where native wildlife and plant species thrive, using topsoils from pre-mined wetlands that contain diverse seed banks. Often, these practices enhance wildlife corridors by connecting reclaimed wetlands to existing preservation wetland systems. In some cases, past environmental damage unrelated to mining can be corrected, such as wetland draining and filling. In 2017, Mosaic reclaimed nearly 300 acres of wetlands and constructed approximately 8,500 linear feet of streams.
  • Thousands of acres of reclaimed land are currently used for cattle grazing and to grow citrus, sod, cypress, and eucalyptus. Mosaic has a team of employees exploring the potential of growing other crops on formerly mined land, such as olives, pomegranates, pongamia, and hops.
  • A world-renowned golf resort sits on 16,000 acres of formerly mined land near Fort Meade, Florida.
  • Mosaic partners with state and local governments to create parks on formerly mined land throughout west central Florida where community members can fish, camp, bike, jog, and play while observing the area’s abundant wildlife.

More than 3,000 Mosaic employees call central Florida home, and the company takes great pride in reclaiming the land for future generations to enjoy.
