  • Nylosolv® Recycling

      In 1999, self-recovery of solvents was already common practice for the South-Hessian (German region) flexo-printing-plate manufacturer. At that time, management installed an OFRU solvent recovery plant of the type ASC-200, including a tank system for manual recovery of flexo-polymer solvent. This installation for continuous recovery was successfully used for approx. 15 years. Since then, ...

  • Landfill remediation with refrigerants and chlorinated solvents

    PROJECT DESCRIPTION Between 1979 and 1980, industrial and hazardous wastes were disposed of at the Site in a series of unlined pits, each of which was used for a particular type of waste disposal. It is reported based on evaluations of manifests that approximately 3.4 million gallons of hazardous liquid wastes and between 3,700 and 4,100 tons of solid wastes were disposed of in the pits ...

  • Energy from waste: the recycling of limed fleshings

    Leather products have been around a long while - there are those who claim that it is the second oldest business in the world. Going back a few millennia, when our earliest ancestors decided that sitting on hard rock was not a soft option, they turned to other materials in order to create more comfortable seating, as well as warmer bedding and improved clothing. Animal skins became the fabric ...

  • Improving performance of a gas stripping-based recovery system to remove butanol from Clostridium beijerinckii fermentation

    The effect of factors such as gas recycle rate, bubble size, presence of acetone, and ethanol in the solution/broth were investigated in order to remove butanol from model solution or fermentation broth (also called acetone butanol ethanol or ABE or solvents). Butanol (8 g L–1, model solution, Fig. 2) stripping rate was found to be proportional to the gas recycle rate. In the bubble size range ...
