NORTH CHARLESTON, South Carolina, April 21, 2022–(BUSINESS WIRE)–Ingevity Corporation (NYSE: NGVT) today announced that a study by consultancy Environmental Resources Management (ERM), London, UK, has determined the carbon negative properties of its Polyfon lignin-based® Dispersant H fully offsets the volume of greenhouse gas (GHG) emissions associated with its manufacture, resulting in a 122% lower carbon footprint than fossil carbon-based alternatives and positively impacting the climate change.

“Ingevity’s research heritage in the area of ​​lignin process chemistry provides us with a wide range of high-quality, durable crop protection products, such as our Polyfon technology,” said Rich White, Vice President senior, Performance Chemicals, and president, Industrial Specialties and Pavement Technologies. “ERM’s study now allows us to quantifiably realize the positive net GHG benefits of Polyfon as we continue to provide renewable solutions that help customers meet their sustainability goals and improve the performance of their products.”

Used primarily as a dispersant in the agricultural industry for a diverse set of crop protection formulations, including biologics, Polyfon is created from lignin, a renewable by-product of the kraft paper manufacturing industry. According to the ERM study, the 2.2 metric tons (MT) of biogenic carbon dioxide — carbon extracted from the atmosphere and stored as carbon in the pine tree during tree growth — offsets the 1.46 MT of carbon dioxide released with the use of energy, materials, packaging and waste associated with Polyfon’s manufacturing, resulting in a negative carbon footprint or a positive benefit for climate change.

The ERM study notes that after application to crops, Polyfon’s innate biogenic carbon is expected to remain in the soil for at least 100 years, storing the carbon in the soil instead of releasing it into the atmosphere to impact on climate change.

ERM is a global provider of environmental, health, safety, risk, social and sustainability consulting services, and has relied on the Life Cycle Impact Assessment (LCIA) method ) of the IPCC 2013 to calculate the GHG emissions of the product in order to assess the potential for climate change. This approach is consistent with the hypotheses of the LCIA study conducted by Franklin Associates for the American Chemistry Council Pine Chemistry Panel. ERM used the Franklin Associates study as a source of data on the carbon footprint of tall oil rosin intake.

This is the fourth study in Ingevity’s ongoing review of the environmental impacts of its main product lines. For more information on ERM’s study of the net benefits of the Polyfon H product, please visit the sustainability page on Ingevity’s website.
