Phytoremediation is an emerging technology where specially selected and engineered metal-accumulating plants to degrade, extract, contain or immobilize contaminants from soil and water. Plants can help clean up numerous sorts of contamination including metals, pesticides, explosives and oil. This technology is an innovative, cost-effective alternative to the more established treatment methods used at hazardous waste sites. Contaminated soils and waters pose a major ecological and human health problem. The cause of soil pollution are the results of the accumulation of heavy metals and...

The increase in the consumption of fossil fuel based energy source such as petrol in the transport sector, due to the unavailability of any other sustainable, renewable and eco-friendly source of energy has lead to problems like global warming and climate change. The first generation biofuel produced from food crop such as corn, sugarcane and the second generation biofuels produced from lignocellulosic feedstock were unable to meet the global demand of bioethanol because of their use as food,high price of these raw material and large amount of land employed for their cultivation. However, the...

The concept of microalgae cultivation as an integrated system in wastewater treatment has optimized the potential of the microalgae - based biofuel production. Microalgal biomass contains lipids, polysaccharides, proteins, pigments and other cell compounds, and it can provide different kinds of biofuels such as biodiesel, biomethane and ethanol; these microorganisms can also be used to produce bioplastic materials and the residual biomass can be applied as fertilizer.

With the growing rate of human pollution the anthropogenic fall outs of industrial development has become more evident and has started to affect our lives. Pollution from heavy metals and dyes bleed into the environment. While ravaging the ecosystem along the way, it also finds its way into our lives and corrupts it. If the lasting damage to the environment due to their persisting nature was not concerning enough, their effects on human physiology is also alarming with effects ranging from multi-organ disorders and even carcinogenic effects. Biosorption is one of the methods that showed...
