Ingevity Corporation (NYSE:NGVT) today announced that a study
conducted by consulting firm ERM, London, U.K., has determined that
the use of Ingevity’s Evotherm® M1 warm mix asphalt additive
offsets the volume of greenhouse gases (GHG) generated in its
manufacture by a factor range of 18 to 23. Factors contributing to
this determination were the replacement of lime, a corrosive
material that contributes heavily to GHG generation, with Evotherm
M1 in the production of traditional asphalt mixes, and the
reduction of production temperatures required for asphalt paving
using a warm mix asphalt as opposed to a traditional hot mix. ERM
is a leading global provider of environmental, health, safety,
risk, social consulting services and sustainability related
services, and relied on an approach consistent with ISO 14040
principles to conduct this GHG life cycle assessment.
Ingevity is the technology leader for pine chemical-based
specialty additives to the asphalt and pavement industry, and a
pioneer in the rapidly expanding warm mix asphalt segment. The
company’s world-leading Evotherm warm mix technology allows
production temperatures to be lowered by up to 100 degrees
Fahrenheit and replaces lime in the asphalt mix, thus improving the
safety of the mixing process.
“The environmental advantages of using our Evotherm warm mix
asphalt technology have been evident to Ingevity and our customers
since it was commercialized,” said Mike Smith, executive vice
president and president, Performance Chemicals, for Ingevity.
“While we have made many measures of our own over the years, ERM’s
study now allows us to quantifiably realize the net positive GHG
benefits of Evotherm, beyond protecting us from emissions during
paving, but also enhancing the roads we drive on by extending the
life of the road.” He added that there is a reason Ingevity has
sold enough Evotherm to pave a road well beyond the moon. “This
technology has proven performance across the globe, and it saves
our customers money.”
According to the results of the ERM study, the GHG impacts
associated with the Evotherm M1 warm mix asphalt additive
manufactured in 2019 totaled 22,575 metric tons of CO2-equivalent.
The total Scope 1 and 2 (as defined by the World Resources
Institute's GHG Protocol Corporate Standard) GHG impact in
manufacturing Ingevity’s Evotherm M1 asphalt additive totaled 404
metric tons of CO2-equivalent, as calculated by Ingevity. This
reflects the energy consumed in the manufacture of the asphalt
additive. ERM used life cycle modeling methods to quantify Scope 3
GHG impact, accounting for 22,171 metric tons of CO2-equivalent,
which included the transportation and manufacturing of raw
materials, the incremental increase in asphalt components required
to make the same weight of asphalt without the use of lime, and the
transportation of finished goods.
The study also considered the GHG benefits from avoiding lime
use and reducing fuel consumption by using Evotherm in asphalt
mixing. By eliminating lime, Evotherm offsets the volume of GHGs by
a factor of 13. Second, a range of fuel consumption savings were
considered when using Evotherm’s warm mix asphalt, rather than the
more traditional hot mix. Based on data from the National Asphalt
Pavement Association (NAPA) and Ingevity, ERM considered the
reasonable range of energy savings to be 15% to 27%. Using this
range, the full total of 22,575 was offset by 413,533 metric tons
of CO2-equivalent in energy savings using the 15% fuel savings
estimate, versus an offset of 510,368 metric tons using the 27%
fuel savings estimate.
Smith noted that the use of Evotherm in asphalt paving provides
additional environmental benefits. Based on Ingevity-generated data
and estimates (separate from the ERM study) Evotherm can reduce
sulfur oxide (SOx) emissions by 75%, nitrogen oxide (NOx) emissions
by 74%, and volatile organic compound (VOC) emissions by 90%.
