In 2015, the United Nations approved the 2030 Agenda on Sustainable Development, an opportunity for countries and their societies to face the challenge of successfully addressing the transition to a more sustainable future for people and the planet, leaving no one behind. The agenda defines a total of 17 Sustainable Development Goals (SDGs) of universal application to promote economic growth, a commitment to social needs and the protection of the environment. For the successful achievement the ambitious and demanding SDGs, individuals, businesses, governments, and higher education institutions should work collaboratively. This paper aims to contribute to the implementation of the SDGs in the mechanical engineering subjects, and to define appropriate indicators and validation processes to assess their level of fulfillment as established in the 2030 Agenda. As a result, better decisions can be made regarding the efforts that universities - including students, academics and researchers and professional services staff - must invest to incorporate the SDGs into their initiatives, structures, and policies.

Forestry waste (eucalyptus sp) was converted into activated carbon by initial flash pyrolysis followed carbonization and CO2 activation. These residues were obtained from a pilot plant in Spain that produces biofuel, the biochar represented 10–15% in weight. It was observed that the highest activation was achieved at a temperature of 800 °C, the specific surface increased with time but, on the contrary, high loss of matter was observed. At 600 °C, although there was an important increase of the specific surface and the volume of micropores, at this temperature it was observed that the activation time was not an influential parameter. Finally, at 400 °C it was observed that the activation process was not very significant. Assessing the average pore diameter it was found that the lowest value corresponded to the activation temperature of 600 °C, which indicated the development of microporosity. When the activation temperature increases up to 800 °C the pore diameter increased developing mesoporosity.
