Order of the National Green Tribunal in the matter of News item published in "The Times of India" Authored by Jasjeev Gandhiok & Paras Singh Titled "Below mountains of trash lie poison lakes" with Centre for Wildlife and Environment Litigation Versus Union of India & Others dated 17/07/2019 regarding disposal of ‘legacy’ waste dumped at Bhalswa, Ghazipur and Okhla dumpsites in Delhi where huge garbage has accumulated over the period of time adversely impacting public health and environment, which requires expeditious scientific and environmentally safe disposal as per applicable rul

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.

Polythene is the most widely used plastic around the globe.

Cities of low and middle-income countries face severe challenges in managing the increasing amount of waste produced, especially the organic fraction.

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.

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. (HUL) at Kodaikanal, Tamil Nadu. The applicant, a local resident, moved this Tribunal on 25.01.2017 objecting to the remediation work undertaken by HUL. It was also prayed that remediation procedures should be as per applicable guidelines in standards. The matter was considered with regard to the standard to be applied.

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 basis of their MIC, two isolates, AK1 (KY569423) and AK9 (KY569424) were selected.

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 carboxylates (citrate and malonate) to uncontaminated and diesel-contaminated microcosms (10 000 mg kg−1; aged 40 days) and determined their impact on the microbial community and PHC degradation.

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 by A. phenanthrenivorans was optimized, which is useful for different purposes like metal and oil removal from water.

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 mass, contact time, different initial concentrations of the metals Cu2+ and Zn2+, and the temperature of the solution during the adsorptive process. By kinetics, the adsorption isotherms and thermodynamics the mechanisms that control the adsorptive process were evaluated.
