Abstract
A method for producing a combustion product that involves dewatering raw paint sludge from spray paint booth operations. The resulting material can provide significant and economical fuel value to combustion processes such as for power plants while also obviating the need to dispose of waste paint sludge in landfills. Additionally the process is inexpensive, safe and free of most problems associated with paint sludge drying.
Claims20
A process of producing a combustible fuel from paint sludge which comprises the steps of:
- a) obtaining raw paint sludge from a painting facility;
- b) subjecting the raw paint sludge to a dewatering process to obtain a combustion fuel component that consists of a paint sludge having a solids content of up to about 50 weight percent;
- and
- c) mixing the combustion fuel component from step b) with carbonaceous material to produce a combustible fuel.
