It is forecasted that by 2050, waste generation will increase to 2.2 billion tons per year, this is due to the poor management of waste, leaving approximately 33% untreated residues. Along with this, in recent years new energy sources have been sought to replace the use of non-renewable energy. The objective of this study is to identify and characterize the experiences in using the procedures to convert waste to obtain energy. To achieve this, we followed the PRISMA method obtaining a result of 109 selected articles that were reviewed for the collection of information. Thus, obtaining as a result that the application of the methodologies provides valorization of agro-industrial waste, utilization of animal waste, biogas generation and generation of electric energy from waste.
