What Is Carbon Black?

Cabot Sarnia is a facilitycarbon black that manufactures carbon black. The use of carbon black dates back to prehistoric times including cave wall dwellings and objects from ancient Egypt.

Carbon black for rubber reinforcement was discovered in England in the early 1900s. It is currently one of the top 50 industrial chemicals and is used in tire rubber, plastics, inks, toners etc. The use of carbon black extends the life of rubber products and reduces our use of natural resources. Cabot is an important player in the circular economy helping industries reduce their waste and their impact on the environment.  

Our Sarnia facility is able to use waste products from our industrial neighbours as input to our carbon black manufacturing process.



Cabot will be making improvements to its Sarnia facility to reduce emissions of sulfur dioxide (SO2) and greenhouse gases. Both SO2 and greenhouse gases are by-products of processes that refine carbon material. These gases are emitted from various industries including, petroleum refineries, cement manufacturing and carbon black manufacturing.  

In 2023, the Ministry of Environment and Climate Change will be phasing in new SO2 air quality criteria to further improve air quality. Cabot is working on implementing its Sustainability Goals which includes targets for reducing these emissions in addition to complying with the new SO2 criteria.

Improvements at the Sarnia facility will specifically address the company’s Sustainability Goals related to: 

  • Engaging with and contributing to the local community
  • Reducing emissions (i.e. greenhouse gas, SO2)
  • Reducing water and energy use and eliminating manufacturing waste
  • Being environmentally compliant at our facilities
  • Investing in capital and technology projects that support our sustainable goals

Working with the Sarnia Community

Over the coming months Cabot will be meeting with the Sarnia community and providing more information on our plans for improvements to do our part to reduce our environmental footprint and improve local air quality.
