Order of the National Green Tribunal in the matter of M. C. Mehta Vs Union of India & Others dated 22/04/2019 regarding the remedial measures to deal with the waste generated during Kumbh at Allahabad. The report received from Justice Arun Tandon, Chairman of the Supervisory Committee states that a …
Polythene is the most widely used plastic around the globe. Among the total plastic waste generated, polythene contributes the maximum share (64%). Various strategies/methods are being utilized to deal with the increasing rate of plastic waste, but among all the methods, bioremediation is regarded as the ecofriendly and widely accepted …
Cities of low and middle-income countries face severe challenges in managing the increasing amount of waste produced, especially the organic fraction. Black Soldier Fly (BSF) biowaste treatment is an attractive treatment option as it offers a solution for waste management while also providing a protein source to help alleviate the …
Processing of biowaste with larvae of the black soldier fly, Hermetia illucens L. (Diptera: Stratiomyidae), is an emerging waste treatment technology. Larvae grown on biowaste can be a relevant raw material for animal feed production and can therefore provide revenues for financially viable waste management systems. In addition, when produced …
Order of the National Green Tribunal in the matter of Navroz Mody Vs Union of India & Others dated 01/11/2018 regarding remediation of mercury contamination on account of manufacture of thermometers by M/s Hindustan Unilever Ltd.

In middle Gangetic plain, high arsenic concentration is present in water, which causes a significant health risk. Total 48 morphologically distinct arsenite resistant bacteria were isolated from middle Gangetic plain. The minimum inhibitory concentration (MIC) values of arsenite varied widely in the range 1–15 mM of the isolates. On the …
Petroleum hydrocarbons (PHCs) are among the most prevalent sources of environmental contamination. It has been hypothesized that plant root exudation of low molecular weight organic acid anions (carboxylates) may aid degradation of PHCs by stimulating heterotrophic microbial activity. To test their potential implication for bioremediation, we applied two commonly exuded …
The present study demonstrates the removal of three toxic heavy metals (lead, cadmium and nickel) by the bacterial strain Arthrobacter phenanthrenivorans from polluted water. The removal efficiency of heavy metals was recorded to be highest in case of lead (79.91%), followed by nickel (47.62%) and cadmium (34.05%). Furthermore, surfactant production …
The objective of this work was to evaluate the removal of Cu2+ and Zn2+ in water by means of the adsorption process using three biosorbents derived from jatropha biomass (bark, endosperm and endosperm + seed coat). The experiments were performed in batch and evaluated the effect of solution pH, adsorbent …
The relationship between microbial biodiversity and soil function is an important issue in ecology, yet most studies have been performed in pristine ecosystems. Here, we assess the role of microbial diversity in ecological function and remediation strategies in diesel-contaminated soils. Soil microbial diversity was manipulated using a removal by dilution …
Discharge of untreated textile effluents containing heavy metals is a serious environmental issue. Biosorption is a promising method for the removal of heavy metals. The present study analyses the biosorption of Cr(VI) from synthetic textile effluent onto tamarind bark biomass as a function of initial metal ion concentration, contact time, …
Crude oil spills are a major threat to marine biota and the environment. When light crude oil spills on water, it forms a thin layer that is difficult to clean by any methods of oil spill response. Under these circumstances, a special type of amphiphile termed as “chemical herder” is …
The upstream and downstream regions of Pathalam bund in Periyar should be de-silted and bio-remediation measures undertaken for saving the river system, suggested experts. They have also called for forming a Periyar River Monitoring Authority for the overall development and sustainability of Periyar river system. The suggestions came from a …
The Centre has released an additional assistance of Rs 37.5 crore for the Buddha Nullah cleaning project. This is in addition to Rs 50 crore earlier provided by the Planning Commission and Rs 16 crore provided under the bio-remediation project for the cleaning of the nullah by the Environment Ministry. …
Long-term measures needed as livelihood of farmers being seriously affected, says Sushma Pilloried by Parliamentarians in both Houses over the state of the Ganga and the Yamuna, Environment Minister Jayanthi Natarajan promised that the government would ensure no domestic effluents pour into the two rivers. “We are making efforts to …
Assessment and remediation of hazardous waste contaminated areas in and around M/s Union Carbide India Ltd, Bhopal (NEERI & NGRI) and tender document for detoxification, decommissioning and dismantling of UCIL Plant (IICT).
VELLORE: Mass cultivation of bamboo and `malai vembu' (a variety of neem grown in the hills) could be taken up in Vellore district for bio-remediation of polluted soil, prevention of pollution from tannery and sewage effluents and to prevent global warming, according to G. Kumaravelu, full time member of the …
Sudha Nambudiri KOCHI: With most people becoming conscious and aware of the quality of food, water and medicine, biosensors have started to play an important role in our lives. They are fast becoming an important tool in research and commercial applications as they can identify specific targets in the human …
Starting with a worst-case scenario of lead contamination of soil, a scientist at Mie University in Japan has demonstrated the use of poultry waste amendment in combination with plant growth to immobilize soil Pb and restore degraded vegetation in shooting range sites. Remediation of Pb-contaminated soils in a shooting range …
