Removal of Heavy Metals from Aqueous Solution/sludges Using Agriculture Waste Materials

Agricultural wastes are unused resources, which in many cases present a serious problem of disposal. However, these waste materials can be used to remove toxic heavy metal from wastewater as they are capable of binding heavy metals by adsorption, chelation and ion exchange. The exchange properties of these wastes can be attributed to the presence of carboxylic, phenolic, hydroxylic groups. In order to enhance cation exchange capacities, these groups may be modified by oxidation, carboxymethylation, acetylation, phosphation. The utilization of agricultural by-products in treating the wastewater/sludges contaminated by heavy metals is an attractive area of research.

Environment and Development Perspectives: Life Cycle Assessment a Tool

Developing countries in Asia have considered economic growth as the sole indicator of development. Monetary gain has dominated over environmental quality and the sustainability of natural resources. If a polluting factory yields a profit now, the effect on generations is forgotten. All this is carried out in the name of development and for the betterment of the quality of life without foreseeing the effect on the environment, which is the key component for sustainable development. Thus, it is necessary to analyze the existing situation and suggest measures to minimize the impacts on the environment and to conserve the finite natural resources. Life cycle assessemnt can be used as one of the tools to identify and assess the environmental burdens of different products or system over the entire period of its life.

Phytoremediation for Treatment of Contaminated Soil

Phytoremediation uses plants to clean contaminated sites. It is the use of plants to partially or substantially remediate selected contaminants in contaminated soil, sludge, sediment, ground water, surface water and wastewater. It utilizes a variety of plant biological processes and the physical characteristics of plants to aid in site remediation. Phytoremediation is widely viewed as the ecologically responsible alternative to the environmentally destructive physical remediation methods currently practiced. Plants have several endogenous genetic, biochemical and physiological properties that make them ideal agents for soil and water remediation. Phytoremediation uses hyperaccumulator and accumulator plants that can remove excess heavy metals from contaminated soils and other contaminants.
