The unceasing effort for improvement is the principal concern of “DIASTASI TECHNICAL COMPANY S.A.” and the guiding perspective of all our employees.

Corporate Social Responsibility is hard to define and even harder to apply in action in a consistent and reliable manner. According to the European Commission’s Green Book, a corporation is socially responsible when it takes into consideration social and ecological issues in its business activities and transactions with other interested parties on a voluntary basis.

A corporation is socially responsible when it gives priority to the principles of entrepreneurial ethics principles, when it considers itself as part of a broader business community, showing concern for environmental conservation and sustainable development, human rights and, therefore, quality of its employees’ everyday life, transparency and safety/security issues in all of its fundamental practices.

It is not coincidental that the concept of Corporate Social Responsibility has been introduced into the international business terminology in recent years. Its importance is confirmed by the fact that it has developed into one of the most demanding sectors of activity for contemporary enterprises.

Corporate Social Responsibility is the mirror reflecting the manner a company conducts itself and how aware it is of its influence on society in general.

In this context, DIASTASI S.A. with the Corporate Social Responsibility actions it undertakes, makes an effort to respond to the complex and particularly demanding environment of the 21st century, to establish new communication channels with its local community and, ultimately, to contribute towards the economic and cultural development of the country.
