Demand for cellulosic ethanol and other advanced biofuels has been on the rise, due in part to federal targets enacted in 2005 and extended in 2007. The industry faces major challenges in meeting these worthwhile and ambitious targets. The challenges are especially severe in the logistics of timely feedstock delivery to biorefineries. Logistical difficulties arise from seasonal production that ...
Dioxins (DXNs) in municipal waste incinerator fly ash were effectively reduced by pelletizing the mixture of ash, cement, and sodium phosphate and reburning the pellets in a laboratory scale bubbling fluidized bed (BFB) furnace. Three types of pellets--A, B and C, of various sizes and compositions were used in the experiments. The efficiency of DXN reduction in the pellet matrix was proportiona...
Compared to single-unit dosage forms, oral multiparticulate drug-delivery systems (e.g. pellets, granules) offer biopharmaceutical advantages in terms of a more even and predictable distribution and transportation in the gastrointestinal tract. There are different pelletization and granulation techniques available to prepare drug loaded spherical particles or granules. Extrusion Spheronization ...
Biotechnology revolution had led the overcoming of different types of therapeutic protein because of their chemical structure can perform specific reactions in the body, increasing efficacy and decreasing side effects. Numerous efforts were made to optimize the physicochemical properties of the proteins used for therapeutic and studied different methods for an effective administration of the pr...
Fardisi, Mahsa Ph.D., Purdue University, May 2015. Investigation of dried distillers grains with soluble (DDGS) susceptibility to red flour beetle (Tribolium castaneum (Herbst)) Infestation. Major Professors: Dr. Linda J Mason and Dr. Klein E. Ileleji. Protecting livestock feed from insect infestation is a common challenge that feed facility managers and farmers have to deal with. It becomes an...
Tensile and impact test samples of ultra-high molecular weight polyethylene (UHMWPE), high-density (HDPE), their blends at various UHMWPE/HDPE ratios were prepared via compression molding injection for thermal, rheological, mechanical characterization. A twin-screw extruder with either a tapered die air-cooling or regular was used to compound extrude the materials prior pelletization molding. T...
Cooling is an important process during the production of pellets (as post-treatment). The pellet cooling significantly impacts quality produced and systematic use energy. However, systems currently in sometimes encounter technical problems, such as clogging perforated grids (sieves), discharge hopper, or degradation may occur. Therefore, a prototype new system using vibrating feeder was tested....
The scope of this paper was to examine the environmental and economic performance alternative household fermentable waste (HFW) management scenarios. In Greece, business-as-usual scheme for HFW is its disposal in landfills as part mixed waste. Within a HORIZON2020 called Waste4think series approaches based on benefits source separation developed. Specifically, separated led drying/shredding pla...
