Development of a novel three-stage fermentation system converting food waste to hydrogen and methane.
In this study, a novel three-stage (lactate-+photo-H(2)+CH(4)) fermentation system was developed, which converts food waste to H(2) and CH(4), with an emphasis on achieving high H(2) yield. The system begins by first fermenting food waste to lactate, rather than acetate and butyrate, using indigenous lactic acid bacteria. Lactate fermentation effluent was then centrifuged, and the supernatant w...
متن کاملPerformance of an innovative two-stage process converting food waste to hydrogen and methane.
This study was conducted to evaluate the performance of an innovative two-stage process, BIOCELL, that was developed to produce hydrogen (H2) and methane (CH4) from food waste on the basis of phase separation, reactor rotation mode, and sequential batch technique. The BIOCELL process consisted of four leaching-bed reactors for H2 recovery and post-treatment and a UASB reactor for CH4 recovery. ...
متن کاملFood waste and food processing waste for biohydrogen production: a review.
Food waste and food processing wastes which are abundant in nature and rich in carbon content can be attractive renewable substrates for sustainable biohydrogen production due to wide economic prospects in industries. Many studies utilizing common food wastes such as dining hall or restaurant waste and wastes generated from food processing industries have shown good percentages of hydrogen in g...
متن کاملEvaluation of Advanced Gravity and Magnetic Concentration of a PGM Tailings Waste for Chromite Recovery
This research was aimed at evaluating the efficiency of advanced gravity and magnetic separations on the recovery of chromite from the fine Platinum Group Metals (PGM) tailings consisting of particles 80% passing 75 µm with about 45% being >45 µm resulting in high chromite losses. The PGM plant tailings were subjected to X-ray fluorescence, scanning electron microscopy and particle size dis...
متن کاملDeep Eutectic Solvents pretreatment of agro-industrial food waste
Background Waste biomass from agro-food industries are a reliable and readily exploitable resource. From the circular economy point of view, direct residues from these industries exploited for production of fuel/chemicals is a winning issue, because it reduces the environmental/cost impact and improves the eco-sustainability of productions. Results The present paper reports recent results of ...
