Background: Biofuels may play a significant role in regard to carbon emission reduction in the transportation sector. Therefore, a thermochemical process for biomass conversion into synthetic chemicals and fuels is being developed at the Karlsruhe Institute of Technology (KIT) by producing process energy to achieve a desirable high carbon dioxide reduction potential. Methods: In the bioliq proc...

Toxicity of raw and bio-slurry treated oily sludge (OS) on Nitrobacter species was determined using standard analytical procedures. The total petroleum content the OS 116.44 ± 3.57 g/kg. TPH rich with Saturate (40.46 0.73 %). This followed by Aromatics (27.94 0.50 %) Asphaltenes (26.58 0.90 %), while NSO fraction had least proportion (5.75 0.47 Contamination coastal soil increased residual conc...

Bioslurry phase reactor augmented with ETP microflora was studied for the degradation of pendimethalin contaminated soil. The effect of substrate concentration on the process performance was evaluated in the slurry phase reactor operated in sequence batch mode under anoxic-aerobic-anoxic microenvironment with a total cycle period of 120 h. The performance of augmented slurry phase system was fo...

This work applied new investigative techniques to assess the locations, distributions, and associations of polycyclic aromatic hydrocarbons (PAHs) in dredged harbor sediment. Dredged materials from the Milwaukee Confined Disposal Facility were collected and homogenized to provide sufficient sample for four month bioslurry treatment testing and for PAH analyses on various size and density fracti...

Techniques for enhancing the biodegradation of oil-contaminated fine soils in a slurry-phase bioreactor were investigated. Using a model system consisting of kaolin particles containing adsorbed n-dodecane as a diesel fuel surrogate, we investigated how increasing the temperature and adding a surfactant and various hydrophobic support media affected the biodegradation rate of n-dodecane. Increa...

The aim of this paper is to quantify the impact incorporating biochar into soils on net nitrogen waste from farming systems in India. It assumes only crop residues that are currently burnt fields used produce biochar. accounts for losses occuring during pyrolysis, and potential savings due capture reactive other parts system industry energy sectors. In 2020, could have been up 67% lost as oxide...

Bioslurries, obtained by anaerobic digestion of fresh organic matter, are emerging as a cheaper and low-impact alternative for synthetic products in agriculture. The aim this study was to evaluate bioslurry from biogas (Biog), plant nutrition FAO (Bfao), lactic fermentation (Blac) biostimulant tomato lettuce plants. Based on toxicity test, 10% dilution finally applied the In lettuce, Bfao Blac ...

This study assessed the potential contributions of improved cookstoves in increasing organic fertilizer availability for application to farmland, greenhouse gas emission mitigation and improvement household finances using Kitchen Performance Test, Controlled Cooking survey focus group discussions. Substitution a three-stone open fire with significantly (p < 0.01) fuel use efficiency by 54% (hig...
