The use of Alternative Fuels, also known as “Co-Processing”, is the use of combustible waste materials as a source of energy in pyro-processing of cement manufacturing plants, lime plants, and in the calcining of other minerals.
Some forms of alternative fuels are:
- Used tires
- Plastic waste (bags, bottles etc.)
- Waste Oils
- Saw dust
- Hazardous Wastes
- RDF (Refuse Derived Fuels)
Conversion to Alternative Fuels benefits the economy of operation by lowering fuel costs. In some cases, a facility that uses Alternative Fuels receives economic compensation for waste elimination (e.g. use of Hazardous Wastes). In addition to energy recovery, there are considerable environmental/green benefits, such as the reduction of emissions and greenhouse gases into the atmosphere by not using natural non-renewable raw materials and fuels such as coal. In certain countries, these savings can be utilized for Carbon Trading credits.
However, because of their inherent characteristics, the implementation of Alternative Fuels present a challenge to use which, if not handled properly, may impact the manufacturing process, product quality, and environmental exposure.
What We Do
At PEC Consulting we provide innovative and thoughtful solutions to help the cement industry and lime industry implement co-processing at their plants and become more cost efficient, which improves their economic competitiveness.
An Alternative Fuels Project will evaluate the characteristics of co-processing and recommend ways to handle and utilize fuels in the pyro-process in the most effective and secure way.
Our scope of work includes:
- Studies for handling and firing Solid Waste Fuels
- Studies for handling and firing Liquid Waste Fuels
- Studies for handling and firing Hazardous Waste Fuels
- Conceptual studies to use whole or shredded tires
- Studies to use gas or petroleum coke (petcoke) as replacement fuel
- Alternative Fuels / Co-Processing Studies for Cement Plants
- Alternative Fuels / Co-Processing Studies for Lime Plants
