**3. Conclusions**

It is the same biomass with its physical and chemical characteristics, which gives indications of the best transformation and recycling treatments, whether in energy conversion or in new organic products useful in the food, cosmetics, and medicine industries, among others.

The energetic potential of the residual biomass resides in its solid mass, where the organic elements based on carbon are found, susceptible to decompose and later become fuel. If the biomass is very humid, this characteristic can help this transformation through biodigestion, water being the environment that allows bacteria to perform this task.

The alternative to transform the residual biomass into electricity with less humidity and the greatest amount of solid mass to be seen is gasification, which offers a synthesis gas (syngas), being an accessible option of economic production for many people.

Another method that takes advantage of bacterial activity in energy transformation is the production of bioethanol, with fermentation, the latter is also crucial in the production of other products, also biologically based, useful as inputs for other industries.
