Final Thoughts The Sustane-able way Repurposing municipal solid waste for bioeconomy benefits By Tristin Mabey A cross the country, approaches are be-ing sought to become more sustain-able and achieve carbon neutrality. Achieving net-zero emissions by 2050 is an ambitious but attainable goal with tech-nology advancements and cross-industry collaboration. A viable option to reduce the coun-try’s reliance on fossil fuels is to tran-sition to a renewable natural resource such as biomass. Harvesting of biomass typically involves wood and agricultural products, but in Chester, N.S., the team at Sustane Technologies is looking at the production a bit differently – by using municipal solid waste. Sustane Technologies is a clean-tech-nology company. They have taken patent-ed separation technologies and integrated these with other known technologies into a complete holistic process. Sustane has built the first commercial-scale facility capable of converting up to 70,000 tonnes of municipal solid waste (MSW) annual-ly. This will result in over 90 per cent of materials being diverted from landfills and into value-added products upon full ramp-up of the facility. Producing biomass from MSW has positive rippling effects on the local mu-nicipality; the extended lifespan of land-fills, value-added products from waste, healthier communities, high-quality jobs and more. The MSW received at Sustane is waste collected after recycling and or-ganic separation by householders at the roadside. tia. At the facility, MSW from Chester and neighbouring municipalities is separated using patented technologies to remove metallic and other pieces of non-organic materials. The remaining mass of material is primarily organic. It is processed using a patented thermal conditioning system, which breaks down the organic biomass, allowing the density difference of any remaining small and micro-sized plastics within the stream to separate. The different material streams are now ready for transformation into products and energy. A small portion of the downstream energy produced from waste is in turn used to supply the energy to the plant to run the entire process, so fully self-SUS-TANE-able! The organic portion of material that has passed through all the separation pro-cesses is transported to a dryer, and further processed into uniform biomass pellets. They are now ready for use in different en-ergy markets. The plastics stream is con-verted through pyrolysis into two grades of synthetic fuels. One grade is suitable as fuel and the other is suitable potentially as feedstock to produce higher-value poly-mers, thus achieving full material circular-ity. The waste stream valorization produc-es a revenue stream, also an important part of the Sustane-able model.

The NSIH works to foster collaboration with a range of enterprises, entrepreneurs, feedstock suppliers, industry partners and members of government to advance Nova Scotia’s bioeconomy. ACHIEVING NET-ZERO Biomass pellets produced using Sustane’s technologies are carbon neutral, offering a competitive advantage for end-users. But the benefits don’t stop there. For every tonne of garbage that comes to the Chester landfill, its carbon emissions are reduced by 2.5 tonnes – that’s equal to 40,000 cars taken off the road. Achieving a more circu-lar economy supports the goal of reaching net-zero emissions, and that’s something we can all support. The bioeconomy is a regenerative sys-tem that works together to repurpose and reuse renewable bioresources. Sustane’s operations are a shining example of what is possible when people work together to make the world a more sustainable place to live. There is an enormous quantity of solid waste generated each and every day around the world. Likewise, there are an abundant number of landfill sites within communities similar to Chester.
