Resum:	Organic waste treatment, including its many strategies and objectives, is one of the most rapidly changing sectors of environmental technology. It is closely related to sustainability and other critical issues, such as global warming. The first years of this century were the time of a transition from traditional technologies for the "disposal of" waste, such as incineration (with poor energy recovery) or landfill (more or less controlled), to biotechnologies that are more profitable, such as composting and anaerobic digestion. However, recent developments are focused on advanced technologies in the framework of a circular bioeconomy, maximizing the production of biomaterials and renewable energy using raw organic waste or digested materials. This perspective paper delves into the second transition in the field of technologies for treating and valorizing organic waste, highlighting emerging technologies such as anaerobic digestion enhanced with nanomaterials or biochar to substitute fossil natural gas, solid-state fermentation to obtain bioproducts that have a "chemical twin" with a high environmental impact, and pyrolysis as a predominant thermal treatment due to the production of biochar, probably the most promising biomaterial in today's research. All these technologies exploit the potential of organic waste for bioenergy production and material utilization, in line with circular principles.
