Entitled "On the Guadarrama National Park: local development and prevention of environmental impacts", the "Aula Ambiental SIGAUS" pulled off in Valsaín, Segovia, at the Guadarrama National Park, with the assistance of more than one hundred participants, including representatives of MAGRAMA, the Autonomous Community of Madrid and of Castilla y León, entrepreneurs, local development organizations, ecologists, managers, environmental protection agents, as well as a broad representation of the City Councils and industrial sectors of the area.

Throughout the morning, speakers such as the Deputy Director General of Waste of MAGRAMA, Maria José Delgado, the Co-directors of the National Park, Patricia Riquelme and Pablo Sanjuanbenito, Deputy Director General for Inspection and Environmental Discipline of the Community of Madrid, Daniel Barettino, the SEPRONA lieutenant, Francisco Rico, and the Head of Projects for the Europarc Spanish Network, Javier Gómez-Limón, shared their experience in environmental management, sustainable tourism and protection of areas of high ecological value such as the Sierra de Guadarrama, accompanied by the General Manager of SIGAUS, Eduardo de Lecea and the Director General for Quality and Environmental Assessment and Natural Environment of MAGRAMA, Guillermina Yanguas, who closed the Day.

“Only considering rural areas, in 2014, SIGAUS collected industrial waste oil from 1,224 municipalities located next to the nationally or internationally protected natural spaces", Eduardo de Lecea recalled in his speech, in which he said that these collections represented a total of 10.1 million kg of waste oil, nearly 7,500 producers attended, and average displacements for treating waste exceeding 100 kilometres.

In this line, during the Day, today's difficult situation on the collection system of industrial waste oils and the challenge to sustain this management which is heavily dependent on the international situation of oil was addressed, given that products manufactured from waste oil, both regenerated base and fuel, compete with other similar ones obtained from first oil refining.

“When oil is cheap, as it is now, there is lower demand for these products, and the industry and management are seriously endangered, affecting the weakest points in the management chain, such as that of collection in rural areas or regeneration itself, a preferential treatment at the environmental level, but also the most expensive, as it is performed in smaller refineries which require large investments" Eduardo de Lecea recalled.
