Exploring RDF in Municipal Solid Waste
Aug 18, 2024
Lecture on RDF for Municipal Solid Waste
Introduction
Speaker: Mr. Gassman
Focus: RDF (Refuse-Derived Fuel) for municipal solid waste
Topics:
Processing opportunities for municipal solid waste into RDF
Company introduction
Status and potential of alternative fuels in the cement industry
Project development and RDF processing
Company Overview
BW Lattenback
Consultants and advisors for alternative fuels processing
Editors of the Alternative Fuels and Raw Materials Handbook
Conduct training and workshops globally
Work with industries such as cement, coal-fired power plants, lime industries
Alternative Fuels
Types: Solid and Liquid
Focus: Solid fuels, especially RDF and biomass dry fuels
Sources: Municipal solid waste, commercial and industrial waste, sewage sludge, waste wood
Cement Industry and Alternative Fuels
High calorific value fuels (e.g., RDF) around 4000-4500 kilocalories
Industry practices (use kilocalories instead of kilojoules)
50-year history in using alternative fuels
Ideal conditions for processing waste (high temperature, long retention time)
Sustainable waste management solution
No residues, unlike waste-to-energy facilities
Global Cement Production
2014 production: 4.3 billion tons
Major production in China (56%)
Growth potential for alternative fuel use
Usage of Alternative Fuels
Germany example: 63-64% of thermal heat demand met by alternative fuels
Worldwide: 150 million tons of alternative fuels used
Potential increase in usage by cement industry due to cost benefits
Alternative Fuel Sources
Examples: Old tires, cardboard, low-recyclable paper, biomass, mixed plastics, carpet waste
Processing Municipal Solid Waste into RDF
Importance of waste sorting to identify usable fractions
Examples of processing in countries like India, Pakistan, Lebanon
Typical RDF yield: 23% of processed waste
Processing Techniques
Pre-processing: Screening, shredding, separation
Facility example: Portugal project
Larger municipal projects: Automated systems, sorting, and separation
Case Study: Tel Aviv RDF Plant
Processes 1500 tons of waste daily, producing 500 tons of RDF
Fully automated sorting and separation
RDF reduces reliance on petroleum-based fuels in cement kilns
Drying Techniques
Importance of drying to reduce moisture content
Biological drying process to reduce moisture in 9-10 days
Increases RDF yield and reduces energy loss
Summary
Future trend: Increased use of alternative fuels globally
Estimated RDF demand with 20% substitution rate: 165 million tons
With 60% substitution rate: 500 million tons
Technological advancements improving yields and processing efficiency
Encouragement to shift towards alternative fuels
Conclusion
Adoption of alternative fuels is rising globally
Opportunities for sustainable waste management
