Cuba: alternative fuel in Sancti Spiritus cement factory
By Oscar Alfonso Sosa
The Siguaney cement factory in the Cuban central province of Sancti Spiritus will soon begin to substitute fuels by industrial wastes, thus applying the so called co-processing method used worldwide.
According to Eduardo Vazquez, head coordinator for environmental management in the factory, this alternative procedure will allow the substitution of over 9 000 tons of fuel a year which mean a million pesos saving.
The expert added that the abovementioned method cheapen the costs of the manufacture process while preserving the environment, a top importance feature to be taken into consideration.
Tests have been undertaken in France and Germany to prove that the co-incineration process applied in the cement factories do not produce dioxin nor furan emissions, two highly toxic chemicals under the Stockholm Convention on Persistent Organic Pollutants.
