The cement plant Portland Valderrivas in Morata de Tajuña is the biggest in Spain and one of the biggest in Europe. In late 2012, very possibly as a result of cost-saving measures due to the steep decline in cement production in Spain since 2008 (linked to the bursting of the absurd building bubble), the company asked permission to change or supplement the fuel they were using. From petroleum coke they would change at least in part to different sorts of waste (which may include tyres, plastic materials, meat and bone meals, sewage sludge and domestic waste). The company got the permission to use co-incineration during summer 2013. This is a new instance of what has happened elsewhere, in a location about 35 km to the south of Madrid not far from the domestic waste incinerator of Vandemingomez. As in similar cases in other countries and in Spain, opposition has appeared against this project at local and regional scale, defining it as an environmental justice conflict. As reported in the newspaper El Pais (21 May 2013), the neighbours, the vecinos, are opposed: "La planta ya quema pulpa de madera pero está a la espera de que la Administración autorice la sustitución parcial del combustible fósil por residuos, como harinas animales, lodos de depuradoras y neumáticos que de otra manera acabarían en el vertedero. No obstante, los vecinos se oponen y aseguran que la quema de basuras en incineradoras pone en riesgo la salud." The greatest concern of these groups are the alleged negative potential consequences for human health and the environment related to the uncertain risk of toxic emissions produced in the chimneys of the industrial installation. Several petitions and street protests have been organized; these groups are also coordinated with other national and international groups working against waste incineration.
