GreenField Ethanol at a Glance…

Founded in the early 1990’s - GreenField has grown to become Canada’s largest

producer of fuel ethanol and industrial alcohol.

GreenField owns and operates 3 dry mill ethanol facilities in Ontario (Tiverton,

Chatham, and Johnstown) and 1 in Quebec (Varennes); as well as 3 industrial alcohol

packaging facilities in Canada and the US.

Annual sales in the range of $700 million (2012); and an employee base of about 420

staff.

Traditional outputs from the manufacturing process include industrial alcohol,

beverage grade alcohols, fuel ethanol, distillers grains, and carbon dioxide.

In 2013 fuel ethanol production will reach 530 million litres, representing about 30% of

Canadian production

Traditional primary inputs are corn (GreenField processes about 60 million bushels of

corn annually); and energy (in the form of natural gas and electricity).

Existing production plants represent an excellent platform for integrating innovative

bio-processing technologies

GreenField is Leveraging its Ethanol Production Assets

GreenField is investing in technology and process improvements to extract additional

value from existing ethanol production platforms

GreenField’s team of research scientists, process engineers, and project managers

are commercializing ‘value-added’ technologies across all its ethanol plants

Through technology and innovation, we are building a sustainable business model

that can thrive without the need for ongoing ethanol incentives in the future

GreenField is developing collaborations with many technology innovators to position

itself as a leading platform for technology commercialization

GreenField’s innovation strategy focuses on:

Creation of new value-added products beyond the traditional ethanol dry mill process

Improvements in yields and process efficiencies to reduce costs

Incorporation of next generation technologies to introduce non-traditional feedstocks

For GreenField – Innovation is the Key to Prosperity

Bio Hydrogen Reactor

Concept: • Process backset (thin stillage

return) from ethanol operations

through an advanced, 2-stage

AD process

• First stage produces hydrogen

from high solids influent.

• Second stage produces

methane from Stage 1 effluent

• Methane can be used as fuel

source for steam generation

• 2-Stage AD process improves

conversion efficiencies while

lowering capital costs

• Technology is also applicable to

any high solids industrial waste

streams.

Gas to Liquids Technolgy - Drop in Fuels

Concept:

• Utilizes clean CO2 from ethanol production

• Reform methane (from AD and supplemented with nat gas) and CO2 into a syngas

• Fischer-Tropsch reactor converts syngas into liquid hydrocarbons

• Hydrocarbon stream distilled into mix of drop in fuels (jet fuel, gasoline, diesel & wax distillate)

Examples of Using Ethanol Plants as Host Sites

Technology Description

Greenhouse Operations Waste CO2 and low grade heat fed from ethanol plant to

support adjacent greenhouse operations

Anaerobic Digestation Large scale AD project sources organic waste streams from

local municipalities/industries. Methane from AD displaces

natural gas for ethanol operations

Thermochemical Ethanol Thermochemical process technology (e.g. Enerkem) uses

industrial and municipal inorganic waste. Co-location

strategy enables infrastructure sharing and water/heat

balancing.

Lignocellulosic Ethanol Co-Location Strategy is key to commercial viability of early

stage, commercial scale, next generation ethanol

technologies

Greenhouse Synergies - Teaming Up for Tomatoes

Concept:

• Utilize excess CO2 and waste heat

streams from ethanol plant to support

greenhouse operations

• Vapours from DDGS dryer stack

condensed to create circulating hot

water supply

• Raw CO2 gas scrubbed and fed into

greenhouse system – boosting crop

growth by 15%

• Enables year-round cultivation of

tomatoes

• Results in a 40% reduction in the

operating costs of the greenhouse

Co-Locating an Anaerobic Digester with an Ethanol Plant

Varennes AD Project:

• GreenField is participating in a PPP

to install a large-scale Anaerobic

Digester

• Policy objective of diverting organic

waste from landfill

• Will process 100K tonnes/yr of

organic waste streams derived from:

• Municipal green bin waste (35+

municipalities)

• Restaurant waste

• Municipal sludge

• Methane from AD will be fed to

ethanol plant to displace nat gas

heterotrophic algae – and is developing an algae-to-lipids process

• Mara’s R&D program intends to produce, scale up and commercialize the

lipid oil from ONC-T18B waste and other inexpensive feedstocks.

• Focus is on improving the algae organism through directed genetic

evolution to enable higher fermentation rates for C5 sugars.

• The Mara R&D team of 15 scientists is located at its research centre in

Dartmouth, NS.

• GreenField’s biomass pre-treatment/dewatering extruder could help by:

• Generating clean streams of C5 and C6 sugars as ‘food’ for prolific

lipids growth.

• Separating lipids solids from water in the post fermentation stage.

•

• GreenField and Mara have commenced a collaboration to advance the

commercialization of our respective technologies.
