The scale-up of mechanochemical methods could play a transformative role in making manufacturing processes the pharmaceutical industry greener by eliminating solvent use and recovery. Combined with energy-efficient continuous processing that consolidates reaction steps, mechanochemistry's environmental economic benefits may translate across product supply chains. Here, we evaluate numerous sustainability green chemistry metrics for producing nitrofurantoin, an active ingredient (API), via...
A comprehensive contemporary cycle for stocks and flows of copper is characterized presented, incorporating information on extraction, processing, fabrication manufacturing, use, discard, recycling, final disposal, dissipation. The analysis performed an annual basis, ca. 1994, at three discrete governmental unit levels−56 countries or country groups that together comprise essentially all global anthropogenic flows, nine world regions, the planet as a whole. Cycles these are presented...
Utilizing domestically produced cellulose-derived ethanol for the light-duty vehicle fleet can potentially improve environmental performance and sustainability of transport energy sectors economy. A life cycle assessment model was developed to examine implications production use in automobiles Ontario, Canada. The results were compared those low-sulfur reformulated gasoline (RFG) a functionally equivalent automobile. Two time frames evaluated, one near-term (2010), which examines converting...
Most life cycle studies of biofuels have not examined the impact process chemicals and enzymes, both necessary inputs to biochemical production which vary depending upon technology platform (feedstock, pretreatment hydrolysis system). We examine whether this omission is warranted for sugar-platform technologies. develop ('well-to-tank') case a corn dry-mill one 'mature' two near-term lignocellulosic ethanol Process chemical enzyme contribute only 3% fossil energy use greenhouse gas (GHG)...
Summary Decentralized approaches to managing urban stormwater are gaining increased attention within the contexts of sustainability, climate change adaptation, and as a means reducing combined sewer overflows (CSOs). This study applied life cycle assessment (LCA) comparing environmental efficiency three equivalently CSOs Bronx River (Bronx, NY, USA). Strategy 1 featured decentralized green infrastructure technologies, while “grey” strategies 2 3 detained, detained treated, respectively,...
Summary A comprehensive annual cycle for stocks and flows of zinc, based on data from circa 1994 incorporating information extraction, processing, fabrication, use, discard, recycling, landfilling, was carried out at three discrete governmental unit levels—54 countries 1 country group (which together comprise essentially all global anthropogenic zinc flows), nine world regions, the planet as a whole. All these cycles are available in an electronic supplement to this article, which thus...
Buildings embody and consume among the largest fraction of energy within built environment, likewise they are responsible for large emissions greenhouse gases (GHGs), often referred to as their carbon footprint. From smalland medium-sized buildings most intensive structures, architects engineers faced with many new challenges in designing retrofitting reduced GHG intensity. Engineers environmental scientists have been examining embodied related more than 40 years (Baird Chan 1983; Buchanan...
Debates surrounding the greenhouse gas (GHG) emissions from land use of biofuels production have created a need to quantify relative GHG intensity fossil fuels. When contrasting fuel and biofuel production, it is energy yield that greatly distinguishes two. Although released disturbed by fuels can be comparable or higher than biofuels, oil typically 2−3 orders magnitude higher, (0.33−2.6, 0.61−1.2, 2.2−5.1 PJ/ha) for conventional sands surface mining, in situ respectively). We found...
Abstract A modeling process was developed to examine the economic and environmental benefits of utilizing energy crops for bioenergy products in northeastern United States. Three (hybrid willow, switchgrass, Miscanthus) that can potentially grow on marginal agricultural land or abandoned mine region were considered analytical production biofuels, biopower, pellet fuel. The supply chain components analysis life cycle processes included feedstock establishment, harvest, transportation,...
Grease trap waste (GTW) is a low-quality material with variable lipid content that an untapped resource for producing biodiesel. Compared to conventional biodiesel feedstocks, GTW requires different and additional processing steps production due its heterogeneous composition, high acidity, sulfur content. Life-cycle assessment (LCA) used quantify greenhouse gas emissions, fossil energy demand, criteria air pollutant emissions the GTW-biodiesel process, in which sensitivity concentration...
Bio-oils produced from small-scale pyrolysis may have economic and environmental benefits for both densifying agricultural biomass supplying local bioenergy markets with fossil energy alternatives to support state policies (e.g., Renewable Portfolio Standards). We analyze the life cycle greenhouse gas (GHG), energy, cost tradeoffs farm-scale bio-oil production via fast of corn stover feedstock subsequent utilization power generation in Pennsylvania. evaluate ramifications either cofiring...
