Themis has developed and uses a process that converts MSW into fuel pelllets which are gasified and converted to liquid fuel. Typically four steps are required to go from MSW to a liquid fuel. 1. the MSW goes through a process facility where all recycling products are removed (glass, aluminum, tin, grade 1 and 2 plastics). The remaining product is shredded, fiberized, and pelletized. 2. the pellets sre sent to the gasifier were it goes through several stages before it is converted into a synthetic fuel “syngas”. 3. the “syngas” goes through several steps were it is cooled, washed and cleaned. 4. the cleaned “syngas” goes through a catalytic reactor were it is converted into a liquid fuel, which is ready to use or be mixed with other bio-fuels. Themis is in the process of designing a 600,000 ton capacity municipal recycling facilities for use at two locations in the United States, and is in process of reviewing two other possible locations in Canada and Australia.

Themis was established in 1998. During the following 6 years Thermis researched and developed the pelletization technology that exists in Canada today.
Themis completed extensive review and consideration of available equipment within the waste marketplace. Themis put emphasis on the utilization of equipment that was best in class with a successful track record but formatted quite differently than existing municipal recycling facilities in either Europe or North America.

The traditional approach to disposing of MSW has been through the use of landfills. MSW landfills in most of the world are filling up to maximum capacity, or being outlawed as they are no longer an environmentally acceptable solution to long term disposal of many waste streams.
In the realm of emissions, methane discharges are of particular concern. According to the US EPA, MSW landfills accounted for approximately 23% of total U.S. anthropogenic methane (CH4) emissions in 2006, and are the second largest contribution of CH4 source in the United States. Emissions from landfills, which received about 64% of the total solid waste generated in the United States, accounted for about 88% of total landfill emissions, while industrial landfills accounted for the remainder. Approximately 1,800 operational landfills exist in the United States, with the largest landfills receiving most of the waste, generating the majority of the CH4.
In numerous metropolitan areas, landfill capacity is under pressure and the high fuel costs are exacerbating the overall cost of waste treatment and disposal. For industrial, chemical and municipal e-waste treatment, incineration and hazardous waste landfills remain the primary approaches, but people around the world are becoming more concerned with greenhouse gases, dioxins, furans, and other carcinogenic gases and particulate production. Due to these concerns, the number of licensed incinerators is on the decrease.
Themis believes a number of factors are driving the increasing interest in higher efficiency waste management technologies that produce commercially acceptable renewable fuels, including:
- Greenhouse gas reduction;
- Lower and predictable energy costs vs. the higher, unstable costs of oil and gas;
- Long run cost stability for MSW to engineered fuel;
- Trend towards tightening international environmental standards (e.g. Kyoto);
- Worldwide requirement for increased use of renewable fuels;
- Rising landfill costs, and
- Population growth, causing per capita waste growth.
The Themis process of pelletizing MSW is an environmentally compatible alternative way of dealing with the waste disposal issue presently facing municipalities throughout the World. The primary objectives of this process are:
- to reduce the volume of methane gas released into the atmosphere – a major contributor of greenhouse gases;
- hazardous MSW streams that are presently disposed of in a landfill into an environmentally acceptable fuel product, used for beneficial use of energy consumers currently dependent on coal, oil or natural gas, to reduce the transportation of significant volumes of MSW;
- to redirect significant volumes and weight of non ha
The process has the capability to capture up to 98% of all recyclable materials that remain in the waste stream post consumer. These recyclables are then sold to market. The balance of the waste stream is then positively selected, combined with other high BTU admixture products, such as poly film, and converted into high-density, high-BTU fuel pellets. This environmentally sound process significantly reduces the number of large over-the-road diesel trucks that have to haul the MSW to landfills, thus reducing truck emissions, as well as the amount of methane gas that is released to atmosphere through the landfill process.
