Domtar is working to build circular economies at each of our mills. In the past several years, the Windsor Mill has gone to great lengths to close its sustainability loop and nurture the forests that support its operations and the people that live and work in the surrounding area. That includes a partnership with local maple syrup producers. The Windsor Mill is one of Canada’s last fully integrated pulp and paper mills, which means it owns forestland — 400,000 acres of it — to support its operations. The mill manages its forests for multiple uses, selectively harvesting trees about once every 20 years. The mill has developed partnerships for the forests to benefit the larger community during the two decades of growing time. One of these partnerships was formed in 2016 to allow local maple syrup producers to harvest sap from the large stands of sugar maples that dominate the land. Since starting its partnership with local syrup makers like Simon Bellegarde five years ago, the Domtar forest’s more than 140,000 taps have yielded enough tree sap to make about 33,000 U.S. gallons of maple syrup each year.
