Purpose: In this article, the utilisation of a case side stream, aqueous paint sludge is studied in accordance with principles circular economy. The study's main objective to find new potential possibilities for generated region and take closer look at role logistics industrial stream utilisation-based business cases value chains. Study design/methodology/approach: via descriptive study context...

Nitrogen removal is needed in microbial fuel cells (MFCs) for the treatment of most waste streams. Current designs couple biological denitrification with side-stream or combined nitrification sustained by upstream or direct aeration, which negates some of the energy-saving benefits of MFC technology. To achieve simultaneous nitrification and denitrification, without extra energy input for aerat...

Performance of a pilot Biofiltration system in removing of Triethylamine (TEA) vapor from air stream was evaluated in this study. Experiments were conducted with two 6-L three section biofilters containing a mixture of compost (60%) and wood chips (40%). The systems were operated at 20±2 and 30±1 ?C. Municipal activated sludge was added initially to promote microbial growth and the systems were...

Sustainable innovations have the potential to drive market systems and behaviours towards greater sustainability, yet collective efforts of various network actors involved in shaping markets for these are poorly understood. This paper examines activities that public-private innovation engage when a side-stream-based sustainable innovation. A qualitative case study exploring technological enable...

In the process of preparing biodiesel using microreactors, cosolvents and homogeneous catalysts are generally used, which adds to separation cost. Hence, this study explored use an opposite-side feed micro-fixed-bed reactor with inner diameter 2 mm produce by transesterification soybean oil methanol without any cosolvent, in a fixed solid base acted as catalyst obstacles. A yield 99.4% was achi...

This study concerns the production of hydrogen from a mixture ethanol and water. The process was conducted in plasma generated by spark discharge. substrates were introduced liquid phase into reactor. gaseous products formed reactor hydrogen, carbon monoxide, dioxide, methane, acetylene, ethylene. Coke also produced. energy efficiency 27 mol(H2)/kWh, it 36% theoretical efficiency. high value ob...

At present, the commercial production of hydrogen is essentially carried out by catalytic steam reforming of hydrocarbons: natural gas and naphtha. However, the instability of the prices of natural gas makes the use of other raw materials increasingly attractive. This research focuses on the development of a technology for producing hydrogen from alternative resources, specifically from two typ...
