© 2021 Elsevier LtdFermentation of cattle manure as the sole carbon source and along with the mixtures of switchgrass and wastewater biosolids by hyperthermophilic cellulolytic bacterium, Caldicellulosiruptor bescii was assessed for the first time in the literature. When cattle manure was used as the sole carbon source, a yield of 82.5 NmL/gVSadded was recorded and that is the highest yield reported from dark fermentation studies on cattle manure so far. The mixture of cattle manure with wastewater biosolids and switchgrass was also utilized by C. bescii and statistical analysis of batch tests indicated the highest (antagonistic) interaction when cattle manure and switchgrass were co-fermented. As a co-substrate, wastewater biosolids produced higher amount of hydrogen compared to switchgrass with a yield of 76.5 NmL/g VSadded. The major liquid end product was acetic acid in all fermentation reactors, which can further be used in a two-stage hyperthermophilic dark fermentation-microbial electrolysis cell system for increased hydrogen production.

Minimization of water and chemical use in a cotton/polyester fabric dyeing textile mill Ozturk, Emrah; KÖSEOĞLU, Hasan; KARABOYACI, Mustafa; YİĞİT, Nevzat Özgü; Yetiş, Ülkü; KİTİŞ, Mehmet (Elsevier BV, 2016-09-01) Water, wastewater and chemical minimization studies were carried out in a textile mill employing cotton-polyester weaving-knitting and subsequently dyeing-finishing. Detailed on-site investigations and analysis on production processes were performed according to Integrated Pollution Prevention and Control principles. Specific consumptions in wet processes were calculated by mass balance analyses. Water/wastewater samples were collected and various parameters were analyzed. Specific wastewater generations an...
Non-thermal production of pure hydrogen from biomass: HYVOLUTION Claassen, Pieternel A. M.; de Vrije, Truus; Koukios, Emmanuel; van Niel, Ed; Eroğlu, İnci; Modigell, Michael; Friedl, Anton; Wukovits, Walter; Ahrer, Werner (Elsevier BV, 2010-01-01) The objectives and methodology of the EU-funded research project HYVOLUTION devoted to hydrogen production from biomass are reviewed.
A methodology for evaluating environmental co-benefits in the transport sector: application to the Delhi metro Doll, Christopher N. H.; Balaban, Osman (Elsevier BV, 2013-11-01) This paper presents a methodology to measure the environmental co-benefits of transport initiatives, defined here as carbon emissions in conjunction with local air pollution. An evaluation tool was developed and then tested on the case of the Delhi metro. The metro is an extensive rail project spanning the Indian capital, which is also the world's first rail based Clean Development Mechanism (CDM) project. However, it has also been a flashpoint in urban policy-making in the city in recent years. This analys...
Biohydrogen production from barley straw hydrolysate through sequential dark and photofermentation Ozgur, Ebru; Peksel, Begum (Elsevier BV, 2013-08-01) Biohydrogen production by sequential operation of dark and photo-fermentation processes is a promising method to produce hydrogen from renewable resources, in a sustainable way. In this study, barley straw hydrolysate (BSEI) dark fermenter effluent (DFE) was used as the biomass feedstock for biohydrogen production through photofermentation. Two different dark fermentation effluents were obtained by performing fermentation with or without addition of yeast extract (YE), using hyperthermophilic dark fermentat...
Sustainable textile production: a case study from a woven fabric manufacturing mill in Turkey Alkaya, Emrah; Demirer, Göksel Niyazi (Elsevier BV, 2014-02-15) The aim of this research was to investigate the applicability of different sustainable production measures and demonstrate environmental and economical benefits in a woven fabric manufacturing mill in Bursa, Turkey. As a result of an Environmental Performance Evaluation (EPE) evaluation, five sustainable production applications were proposed and implemented to decrease water consumption, wastewater generation, energy consumption, greenhouse gas emissions and salt (NaCl) consumption in the company. As a resu...
