Doing Well by Doing Good

It is heartening to realize that being a good neighbor can also be good for business and be good for our planet’s sustainability.

In communities where we have operated for decades – in some cases more than a century – we have developed relationships that benefit our bottom line, as well as the local economy and environment.

Using our assets, energy and water resources more efficiently helps us build a better future together. Here are a few examples of how Domtar is doing this:

Bennettsville (Marlboro), South Carolina: Our mill provides wastewater treatment services for an adjacent manufacturing plant located far from the city’s sewer system.

Ontario: Our Dryden and Espanola mills manage their operations to limit their power draw during the grid’s five peak hours. This contractual arrangement helps reduce the provincial peak, avoiding the need for extra generation, which benefits Domtar, the utility, other power users and the environment.

Rothschild, Wisconsin: Our mill supplies water and renewable biomass fuel to a co-located electric utility, and in return it purchases steam from the utility to make pulp and paper. Our mill also provides energy and water utilities and wastewater treatment services to another co-located business that makes biomaterials from the mill’s pulping liquors.

Windsor, Quebec: Our mill leases land to another party that operates 24 wind turbines, a source of renewable electricity to the Quebec grid.

Making products from greenhouse gases: At five of our mills, carbon dioxide from our fuel combustion is sent to third-party, co-located facilities to manufacture precipitated calcium carbonate, a primary filler used in our paper to make it brighter and smoother.

Plymouth, North Carolina: Our mill sells steam to an adjacent manufacturing facility and also treats their wastewater and storm water.

Cogeneration of electricity and steam: All of our mills have on-site cogeneration. This process is more efficient than conventional electricity generation from the grid, as our mills and co-located businesses can subsequently use the steam in their manufacturing processes after it is used to generate electricity. Some of the electricity is sold to outside utilities. Another benefit from our use of renewable, biomass fuels in our cogeneration processes is our ability to create Renewable Energy Certificates (RECs) to help others meet their energy and greenhouse gas reduction goals.

Transforming our world or a low-carbon future will require more ingenuity and collaboration as we seek to use the Earth’s resources more efficiently.
