The following is an article that discusses the cement emissions, as targeted by environmental groups. It shows that emissions produced by cement plants in Spain insignificant compared with other European countries, while stressing that many other activities also generate the dreaded and dangerous dioxins.
A CIEMAT researcher says that emissions from cement insignificant

investigator Centre for Energy, Environment and Technology (CIEMAT) Maria Luisa Ruiz said today that dioxin emissions to air from the cement industry are "insignificant", mean that Spain is ten times less than the maximum allowed.
So what this expert said today during his speech in the context of a conference on sustainable development and energy recovery in the cement sector held in Oviedo, which has presented A study by the CIEMAT, in collaboration with the Ministry of Environment and the Center for Scientific Research.
The report was performed by analyzing 70 percent of the kilns operating in Spain between 2000 and 2003 also concluded that the emission values \u200b\u200b"no differences" in the combustion of fossil and other alternative resources, from waste such as meat meal and tires. Maria Luisa Ruiz
explained that dioxin emissions are caused by stationary sources like industrial thermal processes, but also in other "vague" and exhaust pipes, cigarettes, incineration of corpses and burning household waste, "not being controlled."
Meanwhile, the managing director of the Education Foundation of Cement and the Environment (CEMA), Dimas Vallina, has stated that the replacement of traditional fuels with waste does not increase "in no case" emissions to the atmosphere can get to reduce "dramatically" when the latter are components of biomass, neutral at the time of counting emissions.
He highlighted the benefits of this technique as a complementary tool to those used by the Administration in the management of waste.
commented in Spain the average rate of replacement of oil by other non-fossil fuels in 2007 stood at 6.5 percent, versus a European average of 18.
By region, highlight the implementation of this technique in Valencia, Andalusia and the Basque Country, with percentages in the three cases above 10 percent.
In Asturias, said, this is a technique still "nascent" which will only be used in central Aboño, "once Tudela Veguín make the necessary investments."
However, Dimas Vallina regretted that so far the two existing cement plants in Asturias, both of the above empresa- no hayan empezado aún a utilizar residuos como combustibles alternativos a los tradicionales.
En cuanto a los residuos utilizados para sustituir el coque de petróleo en este tipo de industrias, se ha referido a las harinas cárnicas, seguidas por los neumáticos usados, los plásticos, los aceites y la madera, aunque ha reconocido que existen acusadas diferencias entre comunidades autónomas en la elección del combustible.
Vallina ha recordado que la Fundación CEMA suscribió en 2004 un acuerdo con la patronal y los sindicatos del sector cementero para incorporar técnicas de mejora medioambiental, "con especial énfasis a los temas de valorización energética y control de las plants. "
Have you considered that this sector is" heir of an old image that has changed radically in the last decade with investments of over five hundred million euros to improve the environmental performance of plants. "
In that regard it ensured that all English cement already have the Integrated Environmental Authorization-required to operate, "or are about to get it" and referred to the central Aboño one of those that already have such permission.
Thus , and within the framework of the conference, the technical environment of Veguín Tudela, Fernando Tresguerres, said that although there is been published in the BOPA, Tudela received such authorization from the Ministry of Environment of the Principality before the deadline, on 30 April.
