Abstract:
This study gathers researches and thesis in Thailand relating to waste disposal by stabilization andsolidification. The purpose is to provide a guideline in selecting waste disposal by solidificationtechniques that appropriate to individual type of waste, binder, and additives and to review theprevious researches to give the direction of future study. It is found that only Cement-BasedTechniques and Lime-Based Techniques are applied in Thailand. In additional, the widely studiedhazardous wastes are heavy metals in forms of synthetic and industrial wastes. Chromium is widelyused heavy metals in most researches. Lead and Zinc are in the second order of the most studiedheavy metals. Heavy metals that have never been study are Barium, Selenium, and Silver. The mostpopular binders found in the researches are pozzolanic materials. The binder fkom natural waste isnot commonly studied. Moreover it is found that the proportions of cement and waste to betransformed into products are less employed in the real application. This is because the researchesare not published to the public and the sizes and shapes of solidification are not practical forapplication. This research suggests that the direction of solidification researches in the future shouldmore focus on other techniques in stabilization and solidification with different binders and wastesthat are previously studied. The purposed study can provide more alternative ways for wastedisposal and strengthen the research in solidification and stabilization.
