The role of wood pellets in achieving climate change goals

10.10, 2020
For decades, the wood waste generated during the manufacturing process has been burned, and the logs and branches discarded after harvest have been left on-site, causing the danger of fire and insect damage. Today, in Canada, more and more waste is converted into wood pellets. These particles are used all over the world to produce clean energy and replace fossil fuels, providing support for achieving important global climate change goals.
Biomass, especially wood pellets, is part of our transition from fossil fuels to climate change adaptation solutions. The energy industry is increasingly using wood pellets to replace fossil fuels in order to significantly reduce greenhouse gas emissions. For example, the Drax power station in the United Kingdom, even if the emissions during harvesting, manufacturing and transportation are included, wood pellets have reduced greenhouse gas emissions by more than 80% compared to coal. Energy producers are not the only companies supporting biomass energy. The world’s major climate change authority-the United Nations Intergovernmental Panel on Climate Change (IPCC) has recognized that biomass has great potential in mitigating greenhouse gases-up to 80% to 90%-as long as it is sustainable and effective Use it.
Sustainable development is a strong argument for Canadian wood pellets. Canadian wood pellets are produced entirely from the residues of sustainably managed forests. These forests are strictly controlled to ensure that Canada's forests will not be depleted over time. These regulations are enforced by the government and supported by independent certification.
Why use particles?
The raw materials received by wood pellet manufacturers are green sawdust, wood chips and low-quality logs with a moisture content of up to 50%.
The pellet manufacturer removes the moisture in the wood fiber, grinds the fiber into a powder, and compresses the wood powder into a particle shape. The heat causes lignin (a substance naturally produced in wood) to bind wood flour together like glue. The result is a dry, highly compressed product that can be efficiently transported over very long distances.
In power plants, wood pellets are treated in the same way as coal. The particles are ground into dust, the dust is combined with air, and the resulting mixture is continuously transported into the flame, thereby generating steam to generate electricity.
