Synthesis of zinc chloride activated eco-friendly nano-adsorbent (activated carbon) from food waste for removal of pollutant from biodiesel wash water

Water Science and Technology, 2021
Food waste has been a complex component added to municipal solid waste, making it a major reason for the evolution of greenhouse gases, foul odour and a dwelling habitat for insects and microbes. Diversion of the mixed food waste (unsegregated) to useful

Alternative methods for the wool wax extraction from wool scouring wastes

Grasas y Aceites, 2007
Wool fibers have to be properly washed out before being processed into fabrics. This scouring process generates high pollutant wastes in two forms, a liquid phase and a solid phase. Both phases contain a large amount of the grease (wool wax) generated by
