The Advantages of the
GHG : Zero Emission
When the Syngas produced by the plant is sold to a neighbouring plant, the Thermoselect process becomes a ”No Emission” plant, which is unique in the world. In addition, it will also reduce GHG emissions in many ways.,
First, by transforming the carbon elements into synthesis gases there is no bio degradation and no formation of methane gas, the main element of GHG, as it happens in landfill sites. (A report by ICF Consulting, dated 2005,confirmed that landfill sites, equipped with methane recovery systems, still escape one third of the methane produced by the degradation organic waste. It is that one third that the Thermoselect process avoids as it transforms 100% of the carbon into synthesis gas. Also, by itself, a 300,000 tons per year plant will reduce GHG emissions by 124,000 tons when compared to conventional landfill.
In addition, when using the syngas generated by the operation in replacement of gas from fossil fuels, it generates even much larger amount of saving of GHG emissions.
As the process requires relatively little space, the complete operation is handled within a closed building. So, a Thermoselect plant has little impacts on neighbours. A plant can be localised within an industrial area that is located near the sources of the waste materials, thereby reducing transport emissions caused by trucks. The syngas produced by the operation is considered as a source of renewable energy by the Government of Quebec.
Lots of Green Energy
The heat treatment of a Thermosect plant is self sufficient in energy. With a 300,000 ton plant (of municipal waste), the syngas generated, net of its internal consumption, generates 56MW of energy which can be sold to surrounding industrial clients.
Also, a further 75 MW of energy in the form of heat can be utilized by operations such as greenhouses or government buildings to fulfill their heating requirements. “Nothing is lost, nothing is created”. So from the input material the plant generates syngas, heat, metals, vitrified granulate, minerals, salt and chemical products (Zinc, sulphur,,,) all reused in industrial markets.
The Thermoselect waste treatment process consumes relatively little water. The water vapour that is produced when cooling the syngas is condensed and is reused as cooling water. All hot water generated by the process is usable in cogeneration to increase the efficiency of the energy internally produced. A water cooling system is part of the standard equipment into Thermoselect plant.
Life Cycle Analysis
The CIRAIG made a “Life Cycle analysis” for the Montreal Metropolitan Community (CMM), which comprised the analysis of all known residual waste technologies applied to Municipal waste. This study, available on the CMM web site, shows that gasification is the treatment process for residual waste that produces the least inconveniences when compared to incineration and landfill.
One reason for this conclusion is that gasification, contrary to incineration, produces no ashes or residues that need to be disposed of in landfill sites.
By-products generated by Thermoselect’s gasification process are: (a) metals which are sold for recycling by the metallurgical industry, (b) vitrified granulates which are sold to construction industry, (c) minerals, salt, sulphur which are sold to the chemical industry, (d) syngas which is used as energy replacement or to produce other forms of energy like electricity.
Finally, as all processes are handled within a closed building with “negative air pressure”, negative impacts like noise and smell are very minimal and limited to hauler truck circulation.
The environmental security of the process
The Thermoselect process operates at high temperatures, up to over 2000 degrees C. This high temperature fractions the hydrocarbon chlorides from the dioxins and furans into simple atoms and destroys them totally. Thanks to this treatment the plant can also process industrial waste and hazardous waste without any harm to the environment. Thermoselet guarantees that no dioxin nor furan will be released from the syngas utilisation. There is no emission issued from the process itself so no possible negative impact to environment, not even a chimney. When syngas is used, the air emissions is far lower than all requirements and regulations of provincial or federal environmental legislations in Canada, USA and Europe.
No matter what types of waste are processed, the emissions that are generated have constantly been far below the limits issued by Germany or Japan, particularly when the syngas is used on site or transmitted to a neighbouring plant. In Karlsruhe, emissions were 80 % lower than the standards issued by the German Government. It is widely recognised that the Thermoselect technology reaches standards unequalled by any other technology.
Advantages and local economic impacts
The main advantages of the Thermoselect technology is the price of the service and of the treatment facility cost in comparison to incineration, the quality of the process and of its useful by-products. All by-products are resold locally as recycled products generated by the process. Also, during construction about 125 employees will be required on site for the construction of the plant, 50 permanent jobs in the plant will also be created for the next 30 years operation.
The many advantages of this technology may look suspicious. Yet, there are 7 plants operating in Japan, the oldest since 1999 and the results of those operations are fully documented, now over many years, and confirmed by opinions of world experts. Those experts all agree that the Thermoselect process is still unique. It is now the only technology that has a sustained track record of generating recycled products from all types of wastes while concurrently generating clean energy without any emission. There is a true proven upgrade alternative to landfill available now!
