During this process, the environment is endowed with symbolism and meaning that, in the course of forming cultural inventories, inspires questions such as: What is the sky, the earth, the stars, the wind, the song of birds, the taste of ripe fruit, the smell of a plant? There are many...

Biomass processed as a result of the torrefaction process acquires new physicochemical properties, especially important when used as a fuel for the power industry. Products of torrefaction are characterized by increased milling susceptibility and energy density and their properties resemble low calorific ...
