Commercially Operational Waste-to-Energy Facilities
Recycling Waste into Clean Synthetic Gas for Generators
Environmentally Sustainable Alternative to Landfills and Incineration
Reducing Climate Change Greenhouse Gas Emissions
Producing Clean Renewable Energy
Every 100,000 Tons of Garbage Diverted from Landfill Equals ~ 1.5 Million Tons of GHG Not Going into the Atmosphere.
Every 100,000 Tons of Garbage Processed into Syngas Fuel for Generating Power Produces 7.5 MW of Clean Renewable Power to the Grid.
Our Waste Resources Processing Facilities Increase Recycling of Marketable Materials.
Our Facilities Enable the Closure of Active Landfills, Which Represent ~ 5% of Canada's GHG Emissions.
Landfill Methane GHG Are 25 Times More Harmful than Automotive CO2 Emissions (Environment Canada).
Nova Scotians should be proud of their nationally leading diversion and progressive waste management program. Nova Scotians introduced the green bin organics diversion programs, and significantly increased recycling across the province.
However, the program has plateaued over the past decade or so, and more than 60% of waste resources that should have been diverted from landfill continue to end up in active landfills, generating millions of tons of harmful GHG.
Nova Scotians send over 400,000 tons of waste to active landfills yearly. Every 100,000 tons of garbage decomposing over decades equates to 1.5 million tons of harmful GHG emissions negatively impacting climate change.

NS climate impacting emissions are consistent with national emission breakdown. The ~5% of waste management emissions includes landfilling and collection.

Landfill fires are even more harmful to the environment and happen more frequently as a result of waste management program changes. Landfill fires can emit dangerous toxic fumes that are harmful for the health and safety of local residents and workers.
Comparing Plasma Gasification and Incineration
and why they are not the same thing…
Gasification is a process in which residual derived fuel is thermally heated in a very low oxygen atmosphere. Output is a hot and calorific gas, the syngas, composed mainly of CO and H2.
Gasification turns the calorific potential of a solid compound into gaseous form, which optimizes its potential for energy recovery.
Gasification has largely been used over the 20th century to produce gas from coal for homes and industry. This technique went out of use when natural gas appeared in the 1960’s.

“Plasma gasification can create more renewable energy than the projected energy from solar, wind, landfill gas, and geothermal energies combined.” – Georgia Institute of Technology
NWSI is partnered with CHO-Power to build plasma gasification facilities.
Morcenx France – CHO Power’s first facility, commercially operational since 2015, was designed for 55,000 tons/year of RDF from over 75,000 tons of mixed solid waste. The energy efficiency achieved is over 35%. The second-generation commercial-sized facility design incorporates several operational upgrades learned during Morcenx facility operations.
This is a graphic representation of the design model for next-generation NWSI facilities. The engineering design incorporates innovative proprietary front-end processing for optimized RDF production. The facilities are scalable to meet jurisdictional requirements.
Plasma Processing Residue
The process results in a 10% by weight of a glass-like slag sand residue, which is inert, non-toxic, clean, and safe and can be recycled and used in civil construction projects.
