AbstractA new solidification technique using cement-glass, which is a mixture of sodium silicate, cement, additives, and initiator of the solidification reaction, was developed for sodium borate liquid waste generated from pressurized water reactor (PWR) plants. The cement-glass could solidify eight times as much sodium borate as cement could, because the solidifying reaction of the cement-glass is not hindered by borate ions.The reaction mechanism of sodium silicate and phosphoric silicate (initiator), the main components of cement-glass, was studied through X-ray diffraction and compressive strength measurements. It was found that three- dimensionally bonded silicon dioxide was produced by polymerization of the two silicates. The leaching ratio of cesium from the cement-glass package was one-tenth that of the cement one. This low value was attributed to a high cesium adsorption ability of the cement-glass and it could be theoretically predicted accordingly.

Basically, nature has the ability to perform the restoration of environmental damage caused by increased human activity, but because of the limited carrying capacity, then the environment has decreased the quality from year to year. In saving the environment, technology plays a role in reducing the risk of pollution, increased efi siensi process, and creating processes and environmentall friendly products, monitoring and prediction of environment quality, environmental pollution control, restoration and environmental improvement. Waste Technology (end of pipe technology) are widely used to cope with environmental pollution, both for liquid waste, solid and air. Waste processing technology developed for the waste can be in accordance with quality standards thathave been established, while monitoring technology has been developed either manually or automatically. For recovery and improvement of technology has been developed remedies and restoration that rely on bacteria in nature.Keywords: end of pipe technology, reuse, recycle, reduce (3R), carrying capacity, and environment pollution
