With MOEFCC and UNEP, TERI releases discussion paper on the state of plastic waste management in India.
While the petrochemical sector is regarded as the backbone of plastic production, it is also considered a yardstick for measuring g

Marine environments are largely unexplored and can be a source of new molecules for the treatment of many diseases such as malaria, cancer, tuberculosis, HIV etc. The Marine environment is one of the untapped bioresource of getting pharmacologically active nonribosomal peptides (NRPs). Bioprospecting of marine microbes have achieved many remarkable milestones in pharmaceutics.

Fresh bark pieces of Mimusops elengiLinn. were used for the isolation of fungal endophytes using standard methods. Mimusops elengi is a small to a large evergreen medicinal plant found all over the different parts of India. Seventy one endophytic fungi belonging to ascomycetes (11.27%), coelomycetes (39.44%) and hyphomycetes (49.29%) were isolated from 200 segments of Mimusops elengi collected from University campus in SagarDistrict, Madhya Pradesh, India.

The search for natural bioactive metabolites having potential anticancer property dates back to the Ebers papyrus written in 1550 BC. Natural products from medicinal plants and microorganisms are the most consistent and productive source for the “first-in-class” drugs. After two decades of research, a great deal of interest has been generated by discovery of remarkable pharmacological agents from endophytic fungi residing asymptomatically within plant tissues.

Metabolites from marine fungi have hogged the limelight in drug discovery because of their promise as therapeutic agents. A number ofmetabolites related tomarine fungi have been discovered from various sources which are known to possess a range of activities as antibacterial, antiviral and anticancer agents. Although, over a thousand marine fungi based metabolites have already been reported, none of them have reached the market yet which could partly be related to non-comprehensive screening approaches and lack of sustained lead optimization.
An Aspergillus aculateus strain was capable of producing agriculturally useful nanoparticles via bioremediation of iron ore tailings

Mining waste such as iron ore tailing is environmentally hazardous, encouraging researchers to develop effective bioremediation technologies. Among the microbial isolates collected from iron ore tailings, Aspergillus aculeatus (strain T6) showed good leaching efficiency and produced iron-containing nanoparticles under ambient conditions. This strain can convert iron ore tailing waste into agriculturally useful nanoparticles. Fourier-transform Infrared Spectroscopy (FT-IR analysis) established the at the

Energy plays an important role in the development of any country. Post the oil crisis the locus of the energy planners have shifted towards renewable resources and energy consewation. Biomass is one of the most promising renewable energy sources and is considered to be widely available, In India. biomass caters to about 65-75% of the rural energy needs, and in Karnataka, nonvcommercial energy sources like firewood, agricultural residues, charcoal and cow dung account for 53.2%. A study was conducted to assess the biomass status in Belagavi district of Karnataka.
Fractionation of sugarcane molasses distillery wastewater and evaluation of antioxidant and antimicrobial characteristics
Kaushik A, Basu S, , Batra V S , Balakrishnan M
Sugarcane molasses distillery wastewater (DWW) was fractionated by ultrafiltration (UF) using 100 kDa and 10 kDa membranes. The isolated fractions were characterized for antioxidant activity and content of melanoidins, total phenols, proteins and carbohydrates were measured. Chemical composition of the fractions was determined using GC–MS analysis and antimicrobial property was tested against pure microbial cultures. DWW has high antioxidant activity with the melanoidins content around 2×103 times the total phenols content. Diafiltration leads to loss in antioxidant activity.

Diffusion dialysis, acid retardation and nanofiltration plants were acquired from Europe and demonstrated in several Indian metal finishing companies over a three year period. These companies are primarily small and medium enterprises (SMEs). Free acid recovery rate from spent pickling baths using diffusion dialysis and retardation was in the range of 78e86% and 30e70% respectively. With nanofiltration, 80% recovery rate of rinse water was obtained. The demonstrations created awareness among the metal finishing companies to reuse resources (acid/water) from the effluent streams.

Treatment of sugarcane molasses distillery wastewater is challenging due to the presence of complex phenolic compounds (melanoidins and polyphenols) having antioxidant properties. Due to zero liquid discharge regulations, Indian distilleries continue to explore effective treatment options. This work examines the concentration of distillery wastewater by forward osmosis (FO) using aquaporin biomimetic membranes and magnesium chloride hexahydrate (MgCl2.6H2O) as draw solution. The operational parameters viz.
