Pilot-scale experiments simulating bio-active landfilling conditions were conducted to evaluate the effects of operating conditions on the kinetics and overall quantities of methane production from anaerobic digestion of real municipal solid waste. Several modalities of leachate injection and pretreatment operations of the waste were studied using six Landfill Simulation Reactors, which were in...
UNLABELLED BACKGROUND Historically, acid pretreatment technology for the production of bio-ethanol from corn stover has required severe conditions to overcome biomass recalcitrance. However, the high usage of acid and steam at severe pretreatment conditions hinders the economic feasibility of the ethanol production from biomass. In addition, the amount of acetate and furfural produced during...
Abstract A continuous lab-scale integrated bio-system was conducted to treat sewage wastewater from Abu-Rawash treatment plant (WWTP). The showed high efficiency in removing chemical oxygen demand (COD), biological (BOD 5 ), and total suspended solids (TSS). experimental analysis results indicated that the maximum COD removal methane yields were 97.6 13.74 mmol CH 4 /Kg at a hydraulic retention...
An integrated approach for efficient biomethane production from solid bio-wastes in a compact system
BACKGROUND Solid bio-wastes (or organic residues) are worldwide produced in high amount and increasingly considered bioenergy containers rather than waste products. A complete bioprocess from recalcitrant solid wastes to methane (SW2M) via anaerobic digestion (AD) is believed to be a sustainable way to utilize solid bio-wastes. However, the complex and recalcitrance of these organic solids make...
The focus of this work is to test variables of fast pyrolysis conditions in a free fall reactor in order to better understand their impact on pyrolysis products, specifically optimization of biooil yields. In the first study, a design of experiments was performed and products were analyzed to evaluate the effects of temperature, sweep gas flow rates, and particle heating time, on bio-oil yields...
Topological management of materials at a Micro-scale is one of the fundamental building principles of nature. This combination of material and structural properties results in marked changes in the properties of solids. Nowadays physicists, chemists, materials scientists and engineers explore those effects by synthesizing, characterizing, and modeling Micro-lattice materials from all material c...
The objective of this study was to determine the effect of increased vitamin D fortification (250 IU/serving) of high-temperature, short-time (HTST)-processed 2% fat milk, UHT-processed 2% fat chocolate milk, and low-fat strawberry yogurt on the sensory characteristics and stability of vitamin D during processing and storage. Three replicates of HTST pasteurized 2% fat milk, UHT pasteurized 2% ...
