On the one hand, the concept of corporate social responsibility (CSR) indicates the commitment and the duties of private companies of integrating in its activities the social, economic and ecological concerns of civil society. Thus, the development and use of biological fuels contribute to a large extent to reducing the negative ecological impact of its activities. On the other hand, citizens and consumers also have a responsibility towards the environment, which they can exercise by acquiring products that have a lower polluting impact. Also, they can carry out what are called "eco-gestures" which are simple and 7

Particularly,the promotion and development of lesspolluting energies are being encouraged, aswell as the production of moreenvironmentally friendly fuels.One of those bio-fuels is bio-ethanol, which isbut ethanol of agricultural origin or ethylalcohol, the same as can be found inalcoholic beverages.
