Production and Coprocessing of Refuse-Derived Fuel: A Review

Abstract

Objective: To review and synthesize the existing knowledge on the production and co-processing of waste-derived fuel, with a focus on the reality of solid waste management in Brazil. Method: This is a narrative review of the literature based on scientific articles available in bibliographic databases such as Scopus and ScienceDirect, as well as technical documents prepared by Brazilian governmental agencies. Results and Conclusion: Studies conducted in the country show that scenarios involving sanitary landfills, along with recycling and composting, have proven more viable in the transition to eco-efficiency. On the other hand, the energy potential of waste-derived fuel produced from urban solid waste has been explored with positive results in replacing fossil fuels and reducing CO2 emissions. However, it is necessary to ensure strict control of environmental impacts and to carry out comprehensive studies to assess the viability of co-processing in different regions of the country. Research Implications: The research contributes to the existing literature, emphasizing the performance of waste treatment techniques that can bring significant environmental gains to a country that still faces major problems related to solid waste management.
