Fossil fuels account for 82% of global energy consumption. In the recent 15 years, RDF becomes a trend to become the best Fossil fuel substitution. Regardless of the type of fuel, calorific value is a very important indicator that determines the value of the fuel. Fossil fuels have a high calorific value, but emit more greenhouse gases during the combustion process. When waste is converted into SRF/RDF, the calorific value of the fuel is significantly increased due to the removal of inert and impurities. The process of sorting allows scrap metals such as iron, copper and aluminum to be reused.
Fossil fuels and RDF (Refused-derived fuel) are two different sources of energy with different characteristics and applications.
Fossil fuels are derived from mineral resources such as oil, natural gas and coal, which are extracted and processed for use in energy production, transportation and industrial production. However, the use of fossil fuels produces large amounts of greenhouse gases such as carbon dioxide, which adversely affects global climate change, as well as problems such as limited resource availability and environmental damage.
In contrast, RDF are combustible organic materials extracted from MSW (municipal solid waste), post-industry waste, landfills, which include paper, wood, textiles, plastics, rubber and organic waste, etc. Wiscon’s RDF primary shredder can effectively disintegrate and downsize incoming waste, followed up by a RDF fine shredder. Study how the RDF conversion process works?
The process of RDF production includes the steps of sorting, crushing, drying and compressing the waste, resulting in a pellet with high calorie. By applying RDF to energy production, it can divert the amount of waste going to landfills and can reduce the costs corporate that spends on fuel. For industries that mainly use coal as fuel, such as power generation, steel, cement, ceramics, chemical industry, etc., RDF can replace fossil fuels and practice carbon peaking and carbon reduction.
As a colclusion, fossil fuel substitution is plausible by RDF, SRF and AFR.
Wiscon Envirotech offers an unique and cost-effective a RDF Process Plant from design to installation and implementation.
The Fossil Fuel Substitution with RDF is mainly manifested in the following aspects:
There is a substantial demand of RDF in the world. According to a report from Fundación Laboral del Cemento y Medio Ambiente, the percentage of alternative waste used in cement plants in Spain between 2017 and 2019 was 30.9%. This is a percentage far below than other European countries such as France and Germany with 43% and 68.9% respectively, or far from the 81 % of Austria, which is the country with the highest proportion of fossil fuel substitution by waste.
However, it is important to note that RDF is not a complete substitute for fossil fuels, especially in areas such as high energy density and special industrial processes. Fossil fuels still have an essential role in many areas.
RDF, on the other hand, is mainly used for specific applications, such as energy recovery and waste treatment. Therefore, the integrated use of fossil fuels and RDF and the promotion of more sustainable alternative energy sources in SRF energy production are key to achieving the energy transition and environmental protection.
