A research shows that converting waste paper into fuel pellets saves $500 per day in landfill disposal costs and more than $6,000 daily in ash handling and other variable costs. Also there will be savings in future coal purchases. Each 1.5 tons of pelletized paper has the energy equivalent of one ton of coal. This provides a savings of $45 per ton in fuel costs.

Advantages of Waste Paper Pellets
1. Converting waste paper into fuel pellets reduces demand for landfill space. As we all know that landfills are the most common means of solid waste disposal like waste paper. If converting waste paper into fuel pellets which are a storable fuel, the demand for landfill space will reduced greatly.
2. Burning waste paper pellets reduces fuel cost.
3. Burning waste paper pellets minimizes hazardous emissions.The waste paper pellets burns cleaner than coal. It produces less nitrous oxides and sulfur dioxide that cause acid rain.
4. As the industrial fuel, waste paper pellets can be easy to handle with equipment designed to handle and burn coal, especially in the stoker or circulating fluidized bed boilers.
