Dr. Esteban Chornet (Ph.D. from Lehigh University; Professor Emeritus from Sherbrooke University) conceived the idea for a waste-conversion technology after being inspired by his father, who used wood waste from his sawmill to make electricity in the late 1930s in Mallorca, Spain. In 2000, Dr. Chornet co-founded Enerkem with his son Vincent Chornet. Under Vincent Chornet's expert guidance, Enerkem has established itself as an entrepreneurial leader in the field of advanced biofuels and green chemicals and grown to 160 employees (as of October 2013).
In 2003, a pilot facility began operations using Enerkem’s technology in Sherbrooke, Quebec.
In 2008, Enerkem announced its plan to launch a next-generation biofuels project in Pontotoc, Mississippi. Later that year the Department of Energy awarded Enerkem up to $50 million in funding for this Mississippi facility. Gov. Haley Barbour of Mississippi welcomed the project stating that “projects like Enerkem fit the definition of what America needs to solve [the U.S.]’s energy problem with more abundant, affordable American energy.” As of December 2013 no work has been started on the Mississippi project.
In early 2011, the U.S. Department of Agriculture offered Enerkem a conditional commitment for an $80 million loan guarantee for its Mississippi project. As of December 2013 no work has been started on the Mississippi project.
In February 2012, the Government of Quebec announced its plan to inject $27 million in a joint venture partnership formed by Enerkem and GreenField Ethanol for the construction of Quebec’s first full-scale commercial cellulosic ethanol plant in Varennes, Quebec.

Enerkem converts non-recyclable garbage into biofuels with the proprietary technology platform it has developed and validated for more than 12 years. The environmentally-friendly technology and process simultaneously diverts waste from landfills and creates a local transportation fuel.
Enerkem’s clean technology platform is a 4-step thermochemical process that consists of:
- Feedstock preparation: The municipal solid waste being used as feedstock is sorted to remove recyclable materials, such as glass, metals, paper, and certain plastics, as well as inert materials, such as ceramic, stones, concrete and sand.
- Gasification: The gasification reactor breaks down the feedstock into its constituent parts or molecules. Enerkem uses a bubbling fluidized bed gasification reactor that evenly distributes air or gas upward through a bed of solid particles, such as sand, and utilizes air or gas velocity to create turbulence. In the same reactor, these broken-down molecules are then blended with steam to produce syngas. This process takes approximately 10 seconds. The resulting synthetic gas is H2 and CO rich, which are essential molecules for use in Enerkem's modern process. Enerkem’s process operates at low-severity conditions using temperatures under 1,400°F and pressures below 5 atmospheres, or atm. Other gasification technologies can only achieve similar conversions through high-severity cracking which requires both higher temperatures and pressures, resulting in greater capital and operating costs for these technologies.
- Cleaning and conditioning of syngas: The syngas is fed into Enerkem’s proprietary syngas cleaning and conditioning system. This process upgrades the syngas to a chemical-grade syngas that can be synthesized into liquid fuels and chemicals. Some of the steps that make up the cleaning and conditioning process include the use of cyclones to remove fine particles present in the syngas, and scrubbing and absorption equipment to remove impurities. Enerkem is able to control the purity and composition of the syngas (i.e. the desired balance between H2 and CO) with its bubbling fluidized bed gasifier and exclusive syngas cleaning and conditioning system.
- Catalytic synthesis: The last step is the conversion of the pure chemical grade syngas (CO and H2) into renewable biofuels and chemicals. A portion of the syngas reacts with a commercially available catalyst to produce methanol, which can either be sold as an end-product or used as a chemical intermediate to form other products. To produce ethanol, methanol reacts with carbon monoxide from the syngas with a commercially available catalyst to produce methyl acetate. The final conversion step in the ethanol production process entails splitting the methyl acetate by inserting a hydrogen molecule that is extracted from the produced syngas. The resulting ethanol is then distilled in a final refining step to improve product quality. Subsequently, process controls and quality analyses ensure that the products, including ethanol, encompass all the required characteristics.
Second Generation Biofuels
Enerkem’s primary focus is the commercial production of cellulosic ethanol. Second generation (advanced) biofuel production, particularly cellulosic biofuel and biomass-based diesel, can address some of the challenges associated with first generation biofuels and are expected to yield greater energy and GHG emissions reduction benefits. The traditional biological process of creating second generation biofuels, unlike thermochemical processes, typically requires specific, consistent and homogeneous feedstock, purpose-bred enzymes and bacteria working in concert and significant water treatment requirements.
Cellulosic biofuels are chemically identical to corn or sugar-derived ethanol, but they are produced from a variety of non-food biomass. They are expected to reduce GHG emissions by at least 60 percent, compared to a 2005 baseline for the gasoline or diesel fuel it supplants.
Enerkem produces renewable chemicals with waste and residues instead of fossil fuels. Enerkem's products are considered green chemicals because they are manufactured from non-recyclable municipal waste, instead of fossil sources like petroleum and natural gas. These chemicals, traditionally derived from fossil fuels, are used to make industrial and consumer products such as plastics, glues, paints, solvents, etc.
Enerkem's technology unlocks carbon molecules and chemically recycles them into advanced biofuels and renewable chemicals. Carbon recycling is a complementary process to traditional recycling and composting, diverting waste otherwise destined for landfills where the carbon locked into still useful material would otherwise be lost.
Commercial Plants and Projects
- Sherbrooke, Canada: Built in 2003, Enerkem’s Sherbrooke facility is the company’s pilot plant. The plant has produced syngas, methanol and cellulosic ethanol. More than 25 feedstock materials have been tested there.
- Westbury, Canada: In operation since 2009, the Westbury facility is used for demonstration. The facility has a throughput capacity of 48 metric tons per day, a 10x scale-up in throughput capacity compared to the pilot plant.
- Edmonton, Canada: This commercial facility, currently under construction, represents the first major collaboration between a metropolitan center and a waste-to-biofuels producer. It is partially funded by the government of Alberta. The facility's planned throughput capacity is 350 metric tons of mixed waste feedstock a day with a production capacity of 38 million litres (10 million gallons) of ethanol per year.
Enerkem is developing other commercial facilities in Varennes, Quebec and Pontotoc, Mississippi. Both plants are planned to produce cellulosic ethanol for commercial consumption. Enerkem was awarded up to $50 million in funding by the U.S. Department of Energy for the plant in Pontotoc as well as a conditional commitment for an $80 million loan guarantee from the U.S. Department of Agriculture. Unfortunately, In April 2012 the Pontotoc Mississippi office was closed and all employees laid-off. As of August 2014, no work has started on the Pontotoc, Mississippi facility. The Varennes project was in turn granted $27 million in financial support from the Quebec government. Additional projects are under development.
The United States generated 459 million metric tons of municipal solid waste in 2011, of which approximately 290 million metric tons, or 63 percent, was landfilled, according to the Waste Business Journal. Much of it consists of valuable materials. By using this municipal solid waste that is otherwise sent to landfills, Enerkem can address the challenges associated with waste disposal and help reduce the need for new landfills. By diverting waste from landfills, Enerkem helps diminish landfill methane gas emissions, which according to the EPA, are significantly more powerful at warming the atmosphere than CO2.
Enerkem is considered the first company to have developed a technology that is capable of breaking down waste materials that are chemically and structurally dissimilar and converting them into a pure, chemical-grade, stable and homogeneous syngas through a process operating at low-severity conditions.
Cellulosic biofuels produced with the Enerkem technology provide a secure source of domestic, renewable fuel that will help reduce dependence on foreign oil and reduce carbon dioxide, or CO2, emissions from the petroleum fuels.
In addition to its environmental benefits, the use of municipal solid waste as feedstock mitigates the need for costly homogeneous feedstock while taking advantage of the waste management industry’s existing collection, distribution and logistics infrastructure, which generates significant savings in transportation costs. It also allows producing biofuels in any region either urban or rural.
Enerkem's facilities are built around the company's proprietary thermochemical technology and are designed to convert a broad range of feedstock from residual materials, such as non-recyclable municipal solid waste, into clean transportation fuels and renewable chemicals. Enerkem’s facilities have a compact footprint and are usually located on landfill sites or near the waste sorting locations. The technology used is based on a modular, copy-exact and scalable approach. The 10 million gallons (38 million litres) per year modules are prefabricated and replicable, which reduces production costs and facilities manufacturing. Each location can have more than one module.
