In an increasingly sustainable world, the new industrial processes are more and more focused on recirculating the waste to upgrade their value. Therefore, the aim of this thesis is to give new life to different kinds of biowaste. To do so, pyrolysis has been implemented. A preliminary literature review has been conducted to identify which are the optimal operating conditions, the reactor configuration that better fits for the present purpose and, if any research has been conducted on this field. The self-energized pyrolysis process has not been investigated a lot, on the other hand the literature on pyrolysis is vast. The three main products of this process are biochar (solid phase), vapors (gaseous phase) and bio-oil (liquid phase).
