The vector water already it is more complex. Catalan polymers plants essentially operate with natural gas, so the vector air is not the most worrying. This year is expected to stop consuming fuel oil sporadically in thermal oil boilers. On the issue of the air, during the past two years the sources of emission in the production facilities have been identified and the official emission measures have revealed that all the sources comply with the rules and record books have opened. Since the founding of the company, in 1995, there is a commitment to "continuing the environmental situation improvement" and its activity is considered by the authorities as "little polluting", as they clarify both Sinforiano Sisniega, technical director, as Jordi Foguet, head of the Department of engineering of the company. The commitment of Catalan of polymers with the environment is strict for some time and is expected to get from the next year the environmental management certificate, either with 14000 or EMAS. These polymers of textile use, in any case, do not produce odor when they are manufactured, with him also in this case is that plastics are not responsible for the "smell of silk". To further complicate the picture, there is the fact that the silk has another company, Poliseda, which manufactures polyester and polyamide, wires that are polymers derived from petroleum and, as such, can be considered plastics, although they are normally used in the textile sector. ![]() The acid sulfídrico, especially, has an unpleasant smell and many precautions and filters that are always put something into the atmosphere escapes.Īccording to La Seda, therefore the smell must be attributed exclusively to the process of derivatives of cellulose, which has to do with the paper and textile sector but not the plastic. ![]() And this for a reason: thread viscose rayon made from cellulose and its manufacturing process involves sulfide and various derivatives of the same. Responsible for the stench it is thus the silk, although not plastics. There is the fact that both Catalan polymers and Viscoseda belong to the group the silk. ![]() The primary responsibility is the viscose rayon yarn plant of Viscoseda, located next to the Catalan of polymers. The plant that Catalan polymers available alongside the autovía of Castelldefels does not produce any odor, despite being one of the biggest European PET polymer factories and polyester fibers. The truth is that plastics have nothing to do with the stench. ![]() Other plants nearby, especially of the trash, also contribute their grain of sand to make the area especially smelling and that intersect several motorways and high passes. Indeed, they insist the silk, the smell comes not only from its factories, although they recognize that they take all the fame. But already for decades that in the area have settled many homes, and other industries without that smell menguara. In those days of the dictatorship of Primo de Rivera, the only affected were four farmers of the area and the numerous birds that nested in the Llobregat delta. For years, motorists that were circulated by the road from Barcelona to the airport have had to close the Windows half way to the unpleasant smell that says goodbye to day and night the floor of the Silk of El Prat de Llobregatno less than from 1926 installed.
