Case Studies

A second life for Canada's railway ties

The biocarbon processed and supplied by Walker is made from repurposed wood from the Canadian railway tie industry, making it an eco-friendly win for multiple industries. As railway ties are replaced by major rail providers in Canada, Walker’s resource recovery process helps to offset the environmental impact. If these railway ties were disposed of in a landfill, they would contribute to the production of greenhouse gas emissions. Instead the scrap ties are recycled and processed into fuel for the steel manufacturing industry.

Carbon offsets from alternative low carbon fuels

Manufacturers can benefit from carbon offsets by replacing a portion of coal with biocarbon in their coking process. The result reduces industry usage of fossil fuels, diverts 20,000 metric tonnes of waste wood from landfills, reduces the manufacturer’s greenhouse gas emissions and ultimately enables them to become more competitive and environmentally sustainable.
