ABSTRACT:
Dust control and/or freeze control compositions and methods of using the compositions are provided. In an embodiment, the present invention provides methods of utilizing the dust control and/or freeze control products. For example, the method can comprise preventing the agglomeration of particulate material comprising coal and the adhesion thereof to surfaces in subfreezing weather. The method can also comprise preventing dust formation from particulate material handling processes. The dust control and/or freeze control compositions can comprise one or more glycerin by-products derived from a biodiesel manufacturing process. The dust control and/or freeze control compositions can also comprise one or more glycerin by-products of transesterification reactions involving triglycerides.
