Actually the rubber powder production from used tyres for recycle may be achieved by means of mechanical, cryomechanical with liquid nitrogen and cryomechanical with air disintegration. In

Applications of nitrogen. Nitrogen\'s low boiling point and non-toxic properties make it an economical choice for recycling tyres through cryopulverisation. In this process, liquid

The SWA does NOT accept septage, wastewater, or liquid waste from RV\'s. Liquid wastes from RV and camper holding tanks, also called black water and gray water, are not normally directly accepted at wastewter treatment facilities.
