There are several reasons why someone might choose to make an RDF pellet or briquette:
Improved Handling:
Reduced volume: Pellets and briquettes are much denser than loose RDF, which makes them easier to store, transport, and feed into combustion equipment. This can significantly reduce associated costs and improve efficiency.
Reduced dust: Loose RDF can be dusty and difficult to handle, posing concerns for workers and the environment. Pelletizing or briquetting minimizes dust generation and improves working conditions.
Standardized fuel: Unlike loose RDF with varying compositions, pellets and briquettes offer a consistent fuel quality, allowing for more efficient combustion and better control over emissions.
Enhanced Combustion Properties:
Higher burn rate: Pellets and briquettes have a higher surface area compared to loose RDF, leading to faster and more complete combustion. This translates to higher energy output and reduced emissions.
Lower moisture content: The production process often involves drying the RDF, resulting in pellets and briquettes with lower moisture content. This improves combustion efficiency and reduces harmful emissions like nitrogen oxides.
Environmental Benefits:
Waste management: By utilizing waste as a fuel source, RDF pellets and briquettes contribute to waste diversion from landfills, reducing greenhouse gas emissions and associated environmental impacts.
Renewable energy: RDF is considered a renewable energy source as it utilizes waste materials instead of fossil fuels. This can help reduce dependence on traditional fuels and contribute to a more sustainable energy mix.
Economic Advantages:
Cost-effective fuel: RDF pellets and briquettes can be a cost-effective alternative to fossil fuels, especially in regions with limited access to traditional energy sources.
Job creation: The production and utilization of RDF pellets and briquettes can create new jobs in the waste management and renewable energy sectors.
However, it’s important to consider:
Investment cost: Setting up a facility to produce RDF pellets or briquettes requires significant investment in equipment and infrastructure.
Emissions concerns: While improved compared to loose RDF, burning RDF pellets and briquettes still generates emissions, requiring proper emission control systems.
Social acceptance: Not everyone accepts the use of waste as fuel due to concerns about potential health risks and emissions.
