to their website, ASR
Group is the world’s largest refiner and marketer of cane sugar. In the United
States, ASR produces sugar under these brand names: Domino Sugar, Florida
Crystals, and C&H Sugar.
April and May 2021, The Vegetarian Resource Group spoke with Michael Burchell,
Senior Director, Global Corporate Quality and Daryl Sabourin, Global Director
of Sustainability, about sugar processing at ASR.
learned that they currently use three different methods for cane sugar
decolorization and purification:
- Cow bone char
- Ion exchange resin using a polystyrene bed (a non-biodegradable, fossil fuel-derived plastic)
- Granular activated carbon (GAC) using coal or coconut husks
Group employs all of these methods at various refineries around the country.
told us that all three processes yield sugar of comparable purity and quality.
Because each type of refining requires its own type of costly, specialized
equipment that has a functional life of 50+ years, changing processing methods
is not frequently done.
refinery converted completely away from bone char filtration in June 2015.
Burchell stated that concern about using animal material, especially in light
of zoonotic diseases, was one reason they made the switch.
the Baltimore location, Domino now uses granular activated carbon (sourced from
both coal and coconut husks) and ion exchange resin for processing.
Yonkers, NY refinery eliminated bone char in the ’80s. It currently uses
granulated activated carbon, as does the South Bay, FL refinery which has
always been bone char-free.
contrast, the ASR sugar refineries in Crockett, CA and Arabi, LA use bone char
the 1990s, 90% of the cane sugar industry was using cow bone char as a filter.
Burchell points out, however, that the ASR Group was already 40% bone char-free
in the ’90s.
estimated that today, 65% of all ASR sugar is bone char-free.
told The VRG that consumers can tell if a particular package of Domino Sugar,
Florida Crystals or C&H Sugar is completely bone char-free if the lot
number appearing on the label begins with 1, 4, or 6.
carbon footprint of cane sugar
Burchell informed The Vegetarian Resource Group that methane gas was the energy
source driving the sugar processing in some refineries. And where granular
activated carbon was used, coal was one of the source materials.
methane gas from fracking and coal from mining are fossil fuels. The burning of
fossil fuels is the leading cause of our climate crisis.
wanted to know more about how the fossil fuel (also called carbon) footprints
of the three industrial methods for cane sugar processing compare. This
information may help educate climate-conscious consumers when they are deciding
which foods and beverages to purchase.
directed us to Daryl Sabourin, ASR Group’s Global Director of Sustainability.
was unable to tell us exactly how the fossil fuel footprints of the three sugar
processing methods compare. His company has not determined what they are.
Sabourin estimated that a complete assessment would cost “at least $70,000.” It
isn’t required by the government and no other companies are conducting this
type of analysis.
consumers want this information and believe the extra cost through raised
prices (or tax credits?) are worth it, companies may start conducting this type
of analysis. A complete environmental impact assessment, including a fossil
fuel footprint analysis, would provide essential information about the total
environmental costs of production methods. This information would allow
businesses to transition toward using only the methods which have the smallest
environmental and fossil fuel footprints and be leaders in
sound sustainability practices.
estimated that for the granular actived carbon (GAC) method, coal, itself a
fossil fuel, would have a higher fossil fuel footprint than coconut husks. He
also estimated that since bone char manufacture and regeneration require
extremely high temperatures for extended times, the bone char method would have
a higher carbon footprint.
