| Abstract |
Climate change is a reality that affects the daily lives of people around the world, with a set of effects that are systematically felt. If there is still discussion about the real cause behind these phenomena, with differing opinions defending the anthropic origin or the origin in terrestrial cycles of geological scale, it seems to be unanimously attributed to the increased concentration of greenhouse gases-particularly to CO2. That is, whatever the source of CO2, it is commonly accepted that this is the cause of the acceleration of the climate change process, and the occurrence of extreme climate phenomena. The use of energy from renewable sources, such as solar or wind, can contribute to the replacement of energy generated from fossil sources. However, these forms of energy are dependent on uncontrollable climatic factors and are, therefore, dependent on the existence of alternatives that, when in reserve, can be activated at any time as soon as the power grid requests their activation. Thus, biomass emerges as an alternative capable of providing this answer, although it also has numerous disadvantages. Torrefaction may be the technology that corrects these drawbacks and allows for the successful use of biomass in the replacement the coal used in power generation, contributing significantly to the reduction of CO2 emissions. In addition to this possibility, it is necessary to introduce forest management models that effectively make use of all material flows generated during forestry operations, creating value-added chains, with a view toward a circular economy and resource sustainability. |
