Refuse-derived fuel (RDF) is a type of fuel made from municipal solid waste (MSW). It is produced by shredding MSW and removing recyclable materials.
Two companies in France, Veolia Group and Solvay France, are collaborating to establish a plant in France that will substitute coal with RDF for energy production. It is believed that “the project will bring greater competitive edge to Solvay and reduce its CO2 emissions by 50%.” Likewise, various cement companies in India are using RDF as a secondary fuel, resulting in reduced carbon emissions.
As is evident, RDF has its advantages and applications; but there are some misconceptions associated with it. Here are a few common misconceptions about RDF:
-
- RDF is the same as traditional incineration: One misconception is that RDF is simply burned like traditional incineration methods. However, RDF is often produced from waste materials that have gone through a sorting and treatment process to remove recyclable and hazardous components. The resulting fuel has a more controlled composition and is often used in specialized waste-to-energy facilities.
-
- RDF is not environmentally friendly: Some people may assume that burning RDF releases harmful emissions and contributes to pollution. While it is true that the combustion of any fuel can produce emissions, modern RDF facilities are designed with advanced technologies to control and minimize these emissions. Moreover, it produces lower emissions of pollutants than coal or oil, and it can be used to generate electricity with high efficiency. Hence, RDF can actually help reduce the volume of waste going to landfills and provide a source of energy recovery.
-
- RDF is a waste disposal solution rather than a waste management approach: RDF is sometimes viewed as a quick-fix waste disposal solution rather than a comprehensive waste management approach. However, proper waste management involves a hierarchy that prioritizes waste reduction, recycling, and other sustainable practices. RDF is typically considered as an option when other waste management strategies are not feasible or for residual waste that cannot be recycled.
-
- RDF is only suitable for developed countries: There is a misconception that RDF is primarily used in developed countries with advanced waste management infrastructure. While it is true that RDF is more commonly utilized in developed nations, it can also be a viable solution in developing countries with limited waste management options, as outlined in our blog about “Potential of RDF in developing countries.” RDF can help divert waste from overflowing landfills and contribute to energy generation in areas where conventional energy sources are scarce.
It’s important to note that the perception and effectiveness of RDF processing plant can vary depending on the specific context, local regulations, and technological advancements.
In conclusion, RDF can be a sustainable and cost-effective solution for waste management and energy generation. Addressing misconceptions is crucial, as RDF contributes to waste reduction, resource recovery, and lower greenhouse gas emissions when produced and used with appropriate technologies and practices.
