Small changes in personnel practices, housekeeping, inventory control, waste stream segregation, material handling and scheduling improvements, spill and leak prevention and preventive maintenance can mean big waste reductions. Perform required maintenance. Segregate waste streams to improve recycling possibilities. Substituting a cleaner fuel can result in reduced emissions to the atmosphere. Switch to gas or distillate oil burners.
Solid fuel yields larger particles and greater amounts of nitrogen oxides than residual fuel.
Recycling Recycling is the use, reuse, or reclamation of a waste after it is generated by a particular process. Fly ash and bottom ash can be recycled in a number of ways. Some of these methods are described below. Fly ash can be either blended with Portland cements or used directly as a partial replacement for the Portland cement. Furnace clinker, bottom ash, and fly ash, after processing, can be used as a light aggregate for producing lightweight concrete blocks and structural lightweight concrete.
