The energy production generated in our plant is expressed with conservative values. As is obvious, each of our technologies has peculiar strengths: gasification maximizes energy yield while plasma torch maximizes inerting.
Some matrices obviously perform better than others.
Our partner RINA Consulting - Centro Sviluppo Materiali S.p.A. conservatively provides the parameter of 0,8% gross as the energy coefficient obtainable from gasification. Value obtained by burning the syngas in a normal internal combustion engine with an efficiency oscillating between 27% and 32%. As a rule, for each ton of matrix, using an internal combustion engine, a yield of approximately 30% is considered, net of self-consumption.
Therefore, through gasification, a ton of organic matrices can produce about 800kWh which, conservatively, we reduce net of self-consumption, which affects between 10% and 15%, to 700kWh.
With regard to a combined cycle of gas turbine and steam turbine (or ORC or advanced thermodynamic) General Electric, today Aero - joint venture between GE Power and Baker Hughes, conservatively certifies it, at 52.1%. An easy mathematical proportion shows that:
700kWh : 30% = X : 52,1%. — X = 1.215,66kWh
Therefore, by adopting a combined cycle, net of self-consumption, a gasifier with good quality organic matrices can easily exceed 1,200 kWh for each ton treated.
Professor Louis J. Circeo of Georgia Tech University, the greatest living expert in plasma torch technology, claims that a ton of MSW entered in a plasma torch provides over 800kWh using an internal combustion engine. We conservatively reduce this value to 550kWh.
As we are not manufacturer of technology linked to the production of electricity, we will choose each suppliers' products on a case by case basis depending on the size of the plant and on the quality of the syngas produced. Each technology that will be adopted will have different yield parameters.
To date, these yields are only possible by adopting such cutting-edge technologies; moreover, the mounting ecological sensitivity pushes to the margins of legality some technologies, once considered also promising, such as the transformation of plastics into fuel oil by autoclave treatment, a technology now banned by almost the whole European Community due to the very high pollution associated with this technology that does not present any applicable improvement margin.
