Abstract
Waste minimization is global challenge for industries and environmental protection agencies to compete in the business through sustainable solutions. Numerous works has been done and also being carried to reduce the levels of solid and liquid waste and possibly be reutilized for various applications. Some of the work includes utilization of waste glass materials and sand for decontamination of heavy metal ions and then fabricating the residual waste into a glass. Initially sand was modified and reconstructed to suit to the composition required for glass preparation. The reconstructed san and glass fiber waste was used to uptake hexavalent chromium from electroplating waste water and then later the used up adsorbent was melted to colored glass. In another study, fly ash from local power station was used for developing pozzolanic materials for concrete production. The results show that flyash composite with cyclodextrin formed composite with competitive pozzolanic features that can be incorporated into cement for concrete production. Lignin is a natural polymer that is found in abundance in pulp and paper mill industrial waste water. This was used to develop composite material for adsorption for removal of various contaminants from waste water.
