In 2010 an estimated 31% of the food in U.S. stores and homes went uneaten, and Americans shipped approximately 34 million tons of food waste to landfills. When food decomposes under anaerobic conditions—for instance, buried beneath other waste in a landfill—it produces methane, a highly potent greenhouse gas. According to the U.S. Environmental Protection Agency, landfills are the third largest producer of methane in the United States, accounting for about 18% of methane emissions in 2013.2

Advance biochar production technique, hydrothermal carbonization (HTC, wet pyrolysis) offers an option to tap the benefits of biomass residues of food industry characterized by high moisture and low calorific value. HTC is more energy efficient due to its low temperature operationsand higher biochar recovery rates (up to 90%).

Application of bio-fuel by-product sugarcane bagasse ash (SBA) as a principal raw material for the manufacturing of bricks was studied. The bricks were developed using the quarry dust as a replacement to natural river sand and lime as a binder.

Order of the National Green Tribunal (Principal Bench, New Delhi - Circuit Bench at Shimla) in the matter of Dharam Pal Vs State of Himachal Pradesh & Others dated 14/08/2014 regarding a large quantity of muck produced by the Project Proponent causing blockage of the river/water source. The Tribunal has directed that the project proponent, in consonance with the recommendations of the Committee appointed by the court in its final report, set-up a stone crusher at Bhallog Nala and start utilizing the muck for conversion into the aggregate especially from the private fields.

Order of the National Green Tribunal (Central Zonal Bench, Bhopal) in the matter of Fly Ash Bricks Manufacturing Welfare Society v. State of M.P. & Ors. dated 28/04/2014 regarding utilization of the fly ash in various industries. The Tribunal noted that there is little coordination and hardly any effort made to utilise the fly ash in various industries and more particularly in Government works contracts.

Order of the National Green Tribunal (Central Zonal Bench, Bhopal) in the matter of Pramod Sharma & Ors. Vs. State of Rajasthan & Ors. dated 18/02/2014 regarding brick kiln units under operation and continuing them at the sites in dispute in District Bundi, Rajasthan.

In this paper, the optimum composition of fly ash and plastic waste in a composite has been established based on various performance tests. The optimum dose of plastic waste in composite is 8% weight of fly ash. Laboratory tests indicated increased resistance to moisture damage in stone Matrix Asphalt (SMA) mixture containing composite as filler. The values of resilient modulus of the SMA mixture containing composite are fairly high compared to SMA mixture containing lime as filler.

This study investigated the use of effective microorganisms (EM) for enhancement of biogas production through composting of solid pyrethrum remains after extraction of pyrethrins (marc). The laboratory scale experiment involved composting of the waste as substrate mixed with EM at different ratios consisting of a control, substrate with EM at of 1:250, 1:500, and 1:1000 v/v. Results show highest production of biogas at EM ratio 1:500 v/v, while biogas produced at EM ratio of 1:250 v/v had the highest methane yield.

Leaking underground storage tanks (USTs) containing gasoline represent a significant public health hazard. Virtually undetectable to the UST owner, gasoline leaks can contaminate groundwater supplies. In order to develop remediation plans one must know the extent of gasoline contamination. Centrifugal simulations showed that in silty and sandy soils gasoline moved due to the physical process of advection and was retained as a pool of free products above the water table.
