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).

Company Profile

Fourth State Energy (FSE) is an international environmental solutions company with roots in Nova Scotia, Canada. 

FSE develops integrated solid waste management solution programs that have a direct impact on reducing the climate change implications of waste management. FSE works with stakeholders to understand their needs and objectives and then designs a unique, fully integrated program solution. These program solutions include:

  • remediating existing landfills,
  • creating collection programs and addressing infrastructure needs,
  • outlining program container requirements and options,
  • creating a customized front-end processing facility based on waste resources generated, and
  • implementing a customized advanced thermal conversion processing system that turns processed resources into synthetic fuel for energy and/or heat generation, depending on client priorities.

Our innovative technology program solutions for solid waste management enable regions to end active landfill dependency and significantly reduce harmful, climate impacting GHG emissions. FSE is currently working with stakeholders in Canada, the Caribbean, South America, and Asia.

Working hand in hand with stakeholders for an environmentally sustainable solid waste and hazardous waste future.

Our Methodology 

We believe in the importance of understanding the current situation and the strategic objectives of our clients. Therefore, we begin right from the start by talking and listening to clients to get clarity and understand their objectives. 

We then design a series of studies to assess current circumstances and and identify the program requirements needed to achieve your objectives. We complete a comprehensive series of studies that provide detailed information on program infrastructure requirements, accurate CAPEX and OPEX projections, and a project development timeline. This is a critical phase as it demonstrates and proves the sustainability of the proposed program solution and enables the seeking and securing of project funding from international and debt financing venture capital investment based on detailed financial data.

During the studies process, we also confirm siting options (based on strategic logistical requirements) and transportation infrastructure possibilities (based on local collection conditions). This phase also enables FSE to engage with local stakeholders and develop relationships for program and project development. The study results and program proposal are then presented to decision makers for approval.Upon approval, project funding is secured and insured, and a detailed feasibility and engineering design process is completed, including an environmental assessment to ensure a transparent and successful project development plan is in place for final approval and initiation.

Project timelines vary depending on location, logistical pipelines, and construction support, but a baseline start-to-commissioning timeline is roughly 24-30 months for a waste-to-energy processing facility, and 20-24 months for a hazardous waste facility.
