Biomass is considered a source of clean, renewable energy. Energy from forest biomass uses residual waste from sawmills, commercial operations and harvesting, low-quality logs, and naturally fallen trees to generate energy.
It is considered renewable because otherwise, this material would be sent to a landfill as waste, and because trees are replanted in sustainably managed forests. Biomass is considered clean energy because, unlike fossil fuels, trees sequester carbon dioxide as they grow. When these trees are replanted, this process happens relatively quick.
Canada is known for responsibly using its vast forests for building materials and for pulp and paper operations. Atlantic Canadian provinces have strict oversight over the industry, with various restrictions on the areas, type and ages of trees you can cut, and requirements to regrow cut forests to ensure woodlots are sustainable.
