Sumario: | Since 2002, a number of experiences have developed in Argentina related to biodiesel production based on waste vegetable oils. The development of these experiences can be interpreted as a socio-technical trajectory in which different social and technical, and different socio-demographic conditions were articulated, generating distinct socio-technical styles. The reconstruction of this trajectory makes possible an understanding of how processes of co-construction of technologies, regulations, economic dynamics and social practices develop. In the case analyzed, this reconstruction will permit observation of how the use of waste material can resolve environmental as well as economic and social problems.
