Waste plastic, both industrial and municipal sources, is posing a major environmental challenges in developing countries such as India due to improper disposal methods. Large quantities of non-recyclable plastic waste get collected in paper recycling plants in Muzaffamagar and other regions in India. The plastic waste is typically in the form of protective covers, thin film, binding coils etc.,...

The Air Force Research Laboratory, Airbase Technologies Division (AFRL/RXQ) is engineering and evaluating the Transportable Waste-to-Energy System (TWES). This trailer mounted system will convert military base waste and biomass waste streams to useful heat and power. The Department of Energy (DOE) Federal Energy Management Program (FEMP) is a TWES funding partner. The first stage of the project...

Polyhydroxyalkanoates (PHAs) is reported as polyesters of hydroxyalkanoates (HAs) which is generally synthesized by numerous bacteria and it is stored in the cytoplasm of cells as an intracellular carbon and energy sources compound. It has been considered as a replacement for conventional plastics. Microbial cell such as Alcaligenes, Pseudomonas, recombinant Escherichia coli and methylotrophs a...

Heavy metal remediation of aqueous streams is of special concern due to recalcitrant and persistency of heavy metals in environment. Conventional treatment technologies for the removal of these toxic heavy metals are not economical and further generate huge quantity of toxic chemical sludge. Biosorption is emerging as a potential alternative to the existing conventional technologies for the rem...

In this study, the physical properties of briquettes produced from two different biomass feedstocks (sawdust and date palm trunk) and different plastic wastes, without using any external binding agent, were investigated. The biomass feedstocks were blended with different ratios of two waste from electrical and electronic equipment (WEEE) plastics (halogen-free wire and printed circuit boards (P...

In this work, sawdust, a biomass waste, is converted into a magnetic porous carbonaceous (MPC) solid acid catalyst by an integrated fast pyrolysis-sulfonation process. The resultant magnetic solid acid has a porous structure with high surface area of 296.4 m(2) g(-1), which can be attributed to the catalytic effect of Fe. The catalytic activity and recyclability of the solid acid catalyst are e...

Anaerobic digestion is an efficient and renewable energy technology that can produce biogas from a variety of biomasses such as animal manure, food waste and plant residues. In developing countries this technology is widely used for the production of biogas using local biomasses, but there is little information about the value of these biomasses for energy production. This study was therefore c...
