About Greenfield Global

Greenfield Global is a leading producer and supplier of high-value, mission-critical raw materials, ingredients, and additives that are vital to businesses and integral to a lower-carbon economy. From start-ups to the largest brands in the world, customers trust Greenfield’s extensive portfolio of premium products, regulatory expertise, and industry-leading service to improve people’s lives and the health of the planet.

We own and operate four distilleries, three specialty chemical manufacturing and packaging plants, and two next-generation biofuel and renewable energy R&D centers. This integrated model enhances supply chain transparency, quality control, custom formulation development, and ultimately customer satisfaction.

Greenfield Global for Renewable Energy

Greenfield’s mission is to unlock the potential of people, partnerships and nature to accelerate sustainable solutions for the health of the planet.

Traditional energy sources like oil and natural gas are formed over hundreds of millions of years beneath the earth’s surface, and which release carbon into the atmosphere when burned. Greenfield believes in a world where our energy comes “from the ground up.” Renewable fuels like ethanol, bio-methane, and renewable natural gas are produced from materials on the surface of the earth, rather than beneath it — making them clean-burning and less harmful to the environment.

We invest in innovation because we know it works. Our dedicated team of scientists and research engineers are focused on developing the next generation of low-carbon renewable fuels. Our goal is to continually make our operations even more efficient and our products more sustainable — all while reducing our own carbon footprint.


Greenfield is Canada’s largest ethanol producer. Ethanol is a high-octane, economical, clean burning gasoline additive that reduces air pollution and greenhouse gas emissions. Ethanol is blended at roughly 9% in all gasoline used in the provinces of Ontario and Quebec to reduce greenhouse gasses and improve engine performance, while supporting the agriculture economy.

Renewable Natural Gas (RNG)

In addition to its partnership in, and operating of, Quebec’s largest anaerobic digestion facility, Greenfield’s Engineering & Technology team has developed advanced anaerobic digestion technologies that accelerate the conversion of organic waste into RNG. Through other collaborations, we are commercializing the production of RNG from forestry waste. We believe in turning today’s waste into tomorrow’s fuels.

GreenField Global Believes in a Circular Economy

A good example is our collaboration with Truly Green Farms, a large tomato greenhouse grower located adjacent to our Chatham ethanol plant. By providing biogenic carbon dioxide released during fermentation, we are helping improve tomato crop yields. As well, a steady flow of waste heat from our ethanol plant is circulated through the greenhouses, eliminating the need for heat from natural gas-fired boilers. As a result, the Truly Green operation is among the most energy and cost efficient greenhouse operations in North America.

Examples of Current Projects

Here are examples of current projects!


  • In collaboration with municipal partners, we have developed a large-scale anaerobic digester adjacent to our Varennes ethanol plant to convert organic waste into biogas (methane and CO2).
  • The enterprise is known as Société d’économie mixte de l’est de la couronne sud (SEMECS).
  • This project will remove 40 000 metric tons of organic waste each year from local landfills.
  • The biogas is piped into Greenfield’s ethanol plant, thereby significantly lowering the carbon intensity of the ethanol produced.


Advanced Anaerobic Digestion Technology

  • In Chatham, Ontario, we are developing a new advanced anaerobic digestion (AD) technology that accelerates the process of turning waste into renewable natural gas and hydrogen.
  • Greenfield’s patented technology accelerates the AD process, and can handle a much higher organic loading rate than conventional anaerobic digestion systems, thereby producing bio-methane with less energy, and with a smaller footprint than traditional AD systems.
