Order of the National Green Tribunal in the matter of Varun Sheokand Vs. State of Haryana & Others dated 11/10/2017 regarding dumping of fly ash from thermal power plant, Faridabad. It is stated by the Counsel appearing for the Project Proponent, National Highways Authority of India that they are lifting the fly ash from the dumping site and are utilizing it for different purposes. It is further stated that the site shortly would be cleared in its entirety and would be filled in accordance with the prescribed rules.

Order of the National Green Tribunal in the matter of Almitra H. Patel & Anr. Vs. Union of India & Others dated 22/09/2017 regarding waste dumping at the Ghazipur landfill site in Delhi. Tribunal directs NCT Delhi, East Delhi Municipal Corporation to place before the Tribunal, a Report and Action Plan in regard to the manner and methodology that would be done by them for the purpose of dealing with segregation, compaction and disposal of the deposited waste of the Ghazipur land fill site as well as the fresh waste of nearly 800 MT that is being brought to this site everyday.

Entrepreneurs are finding profits turning human waste into fertiliser, fuel and even food.

Order of the National Green Tribunal in the matter of Elephant Energy Private Limited Vs. Municipal Corporation, Shimla dated 11/09/2017 regarding the functioning of the waste to energy plant in Shimla, Himachal Pradesh. Counsel appearing for the Project Proponent submits that their Waste to Energy Plant is not functional as the machinery of the energy plant has been sent back to Germany for appropriate mechanical and other corrections.

Plastics are synthetic polymers derived from fossil oil and largely resistant to biodegradation. Polyethylene (PE) and polypropylene (PP) represent ∼92% of total plastic production. PE is largely utilized in packaging, representing ∼40% of total demand for plastic products with over a trillion plastic bags used every year. Plastic production has increased exponentially in the past 50 years.

Energy harvesting performance of an efficient flexible bio-piezoelectric nanogenerator (BPNG) is demonstrated, where “bio-waste” transparent fish scale (FSC), composed of self-assembled and ordered collagen nano-fibrils, serves as a self-poled piezoelectric active component, exhibiting intrinsic piezoelectric strength of −−5.0 pC/N. The dipolar orientation (∼19%) of the self-polarized FSC collagen is confirmed by the angular dependent near edge X-ray absorption fine structure spectroscopy.

Polyethylene (PE) is the largest-volume synthetic polymer, and its chemical inertness makes its degradation by lowenergy processes a challenging problem. We report a tandem catalytic cross alkane metathesis method for highly efficient degradation of polyethylenes under mild conditions. With the use of widely available, low-value, short alkanes (for example, petroleum ethers) as cross metathesis partners, different types of polyethylenes with various molecular weights undergo complete conversion into useful liquid fuels and waxes.

The catalytic conversion of waste cooking oil (WCO) with high acid value (120.37 mg KOH/g) to biodiesel has been studied in low-cost SO3H-functionalized quaternary ammonium ionic liquid as catalyst. The ionic liquid (IL) catalyst was efficient in catalysing the simultaneous esterification and transesterification reactions of WCO and methanol.

Agro wastes such as carrot peel, onion peel, potato peel and sugar beet peel are products subjected to saccharification process by Penicillium sp. for the hydrolysis, this process was followed by the fermentation using yeast Saccharomyces cerevisiae for the production of alcohol which was fermented at 14, 21, 28 days to produce alcohol. The aim of the study was to determine alcohol content of fermented agro wastes based on different fermentation time. The fermented product was purified by primary distillation process at 780C and the fraction was collected.
