The effect of microorganisms on the biomodification of montan resin from lignite.

Montan resin (MR) is an industrial by-product or solid waste generated during the production of refined montan wax and is not typically reused. In this paper, a bio-modification method using three strains of microorganisms, (AV), (PA), and (PC), was studied to promote the performance and bio-function of MR so that MR could be recycled. MR can be degraded by these three microorganisms, and their weight loss rates were similar over the treatment period of 15 days.

Chemical modification of montan resin by peracetic acid and agricultural application of its modified products.

Montan resin (MR) is a by-product produced during the refinement process of montan wax extracted from lignite and has no usage yet. Chemical modification is an effective method to change the material property for expanding or converting the application area of the material itself. Our previous study found that the high hydrophobicity of MR is the primary limiting factor for its utilization in agriculture.
