Avoid the environmental impact of throwing down the drain and is an environmentally friendly fuel that can even occur in a home, albeit with limitations
Fry an egg can feed the stomach but also the repository of the car. Conveniently collected and processed used cooking oil can become fuel diesel. Its use is doubly eco- al evitar que contamine el medio ambiente cuando se aprovecha como biocombustible. Diversos sistemas permiten incluso producirlo en casa, aunque para consumirlo con plenas garantías se aconseja su elaboración industrial. Por su parte, cada vez más municipios españoles ponen en marcha proyectos para potenciar este biodiésel, aunque su desarrollo todavía es incipiente. En este sentido, la colaboración de los consumidores es fundamental para su desarrollo.

Ventajas del biodiésel de aceite usado
El correcto reciclaje del aceite usado, como se apunta en la Escuela de Reciclaje en el Hogar Consumer Eroski, passed by depositing it in a suitable container and bring it to specific locations for collection, as collection points.
However, the lack of awareness, ignorance, or the few facilities for collection are the vast majority of consumers to pour it into the trash or down the sink, which can pose a serious environmental problem and public health . For starters, this residue contributes to the reproduction of potential harmful bacteria in the pipes, the blockage of the same to solidify and the generation of odors in the home.
But that's not just the problem: one liter of oil can contaminate domestic thousand liters of water and cause major disruptions in natural ecosystems. For example, you can attach to the gills of fish, and on the surface of rivers create a layer that impairs oxygenation.
Therefore, many experts recommend using this oil used to produce biofuel. Jose Santamarta, head of the World Watch Institute in Spain says, "is easy, accepted and is the most reasonable way to produce biodiesel, solving a problem of environmental pollution."
A single quart of oil can contaminate domestic thousand liters of water and cause major disruptions in natural ecosystems
also use diesel fuel allows reducing production costs, and it is a good raw material, according to a study by a team of scientists from the University of Castilla la Mancha and the University of Antioquia (Colombia), which has shown that does not generate more emissions CO2 pure oils.
However, the production of this type of biodiesel is rather small, due to various reasons of technological, economic, or regulatory. Also in Spain, the big oil companies, which are not interested in selling this type of biodiesel, largely control the distribution at gas stations. Buses
waste oil biodiesel
Buses are vehicles idóneos para la utilización de este tipo de biodiésel y de hecho, diversas ciudades españolas cuentan entre su flota urbana con autobuses ecológicos que ya lo consumen.
El autobús puede ser un ejemplo en el que se unan diversas prácticas ecologistas. Los consumidores, además de utilizar este medio de transporte público, pueden reciclar el aceite usado de sus casas para que se convierta en su combustible. Así lo ha visto Stagecoach, una de las compañías de autobuses más importantes del Reino Unido. Sus responsables reducen el precio del billete a los usuarios que entreguen su aceite usado a la empresa, que utiliza vehículos con este tipo de biodiésel.
¿Se puede hacer homemade biodiesel?
The process for converting waste oil into biodiesel is not very complicated in theory: basically consists of mixing it with alcohol such as methanol. Therefore, propose initiatives to transform consumers used oil from their kitchens in free biofuel vehicles. In this sense, the Internet can even find sites that detail how to do it home. ESOC
Antony Berretti The driver declined to give an example that the idea is possible. To this end, it was proposed tour several European countries, including Spain, with a van converted by himself, so he could fill up your tank with vegetable oil leftovers from restaurants.
Meanwhile, some companies offer even sell it to consumers and business to do it. For example, the U.S. company Greasecar Vegetable Fuel Systems conversion kits sold each priced between 500 and 1,300 euros, and according to its makers is amortized over several months to obtain free fuel.
In Internet you can find sites that even details how to do so homemade
The British company Green Fuels is also directed to the domestic market with FuelPod2 biodiesel processor. With a price of about $ 3,000, this set is capable of producing, according to its leaders, up to 50 liters of biodiesel per day from various oily residues. Its size -60 inches in diameter and 1.40 meters high, are designed so you can be stored in a basement or garage.
However, some experts point out the limitations of producing this type of biodiesel in a home. Gloria Etxebarria, technical Renewable Energy Department of the Basque Energy Board (EVE), explains that the raw material is a "potpourri", as some oils are more used than others, more burned, with different impurities, some are sunflower, soybean others, etc.
So add this specialist EVE, although it may be true that these systems operate on a small scale landlords are not able to produce a fuel with the EN14214 standard, which specifies how it should be and accept biodiesel manufacturers. In this way, a biodiesel that does not meet this criterion would lose the guarantee in case of vehicle breakdown.
also Emilio Font de Mora, Head of Biofuels Association of Renewable Energy Producers (APPA), ensures that the home production may even be illegal if not assume a fairly strict set of requirements in the environmental (the Methanol is a dangerous product) and tax (you have to declare the production, but after the exemption).
Proyectos ecológicos y solidarios
El reciclaje del aceite usado puede dar lugar también a ejemplares experiencias que combinan no sólo valores medioambientales, sino también solidarios. Cinco vecinos en paro del barrio Suerte de Saavedra, en Extremadura, fundaron en 2004 una cooperativa con el doble objetivo de crear puestos de trabajo y proteger el medio ambiente recogiendo el aceite usado para su posterior transformación en biodiésel.
Por su parte, la ONG Madre Coraje, junto al Ayuntamiento de Málaga, puso en marcha en 2007 una iniciativa para recoger el aceite usado de esta ciudad andaluza para convertirlo en jabón y mandarlo a Perú. El aceite que no se utiliza para este fin, una vez filtrado, sold to companies that are responsible for turning it into a biodiesel for city buses in the city of Málaga. In this way, it also gets money to continue funding projects that Oxfam has in Peru.
biodiesel with waste oil in Spain
The production of biodiesel with waste oil in Spain is carried out by public institutions or universities that collect the waste and carry biodiesel production plants, as responsible for APPA.
Thus, more and more English municipalities to carry out interesting projects for recycling waste oil for processing into biodiesel. The system usually involves the installation of special containers for consumers arising from the used oil have been stored in an airtight container like a plastic bottle. It must deposit oil from frying, roasts, canning, fat spoiled or expired, and in no engine oil, lubricants, mayonnaise, sauces or prepared or mixed with food waste or other waste. Subsequently, a specialist in charge of transport and processing into biodiesel.
For example, the municipality of Madrid and Segovia Loeches San Cristobal recently put up a pilot project runs until 2009. The consistory-filter funnels distributed free to citizens to keep the oil in a plastic bottle. Once filled, is placed in special containers located in different parts of town, since the system even lets you recycle the container.
citizen collaboration is essential. Consumers can ask their consistory if carried out any similar project, and if not, request
Meanwhile, another unusual initiative, which also incorporate elements of environmental education, the Institute is The Espeñetas Orihuela, Alicante. His students recycle used oil from their homes and make it into the central laboratory into biodiesel. The fuel obtained is then used in the heating furnace of the institute.
Normally, municipal officials tend to report publicly on the implementation of these projects, since the cooperation of citizens is essential. In this sense, consumers can ask their consistory if carried out any similar project, and if not, apply.
For plants in Spain using 100% waste oil and to some extent with other oils, are: Biodiesel Asthor in Gijón; Biofuels De Castilla, Valdescorriel (Zamora); Bionor Transformation in Berantevilla (Álava), Bionet Europe in Reus (Tarragona); Bionorte in San Martín del Rey Aurelio (Asturias) and Del Valles Stocks in Montmelo (Barcelona).
