Facing supply uncertainty of bulky wastes, the capacitated multi-product stochastic network design model for bulky waste recycling is proposed in this paper. The objective of this model is to minimize the first-stage total fixed costs and the expected value of the second-stage variable costs. The possibility of operation costs and transportation costs for bulky waste recycling is considered ...

5-Aminosalicylic acid (5-ASA) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-NSA) in acidic media. In this work, electrolytic reduction of 5-NSA in alkaline media is presented. Reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the pH for isolation of product are investigated. The yiel...

We also describe tests wi...

Atmospheric pressure non-equilibrium water vapour plasma technology was developed, tested and partly employed for fuel conversion and production of hydrogen-rich gas. The results of experimental investigation on plasma source characteristics dependent on the anode material and prevailing external factors are presented. The effect of plasma source anode material on the elemental composition of e...

The recycling of chemicals and generation of alternative energy are central topics in the efforts toward sustainable development. Among these, research on plastics recycling and fuel cells has received significant attention, with the aim of designing novel catalysts to improve yield and efficiency. We highlight our work on these areas focusing on the chemical depolymerization of polyethylene te...

A high full-electrode basis capacity secondary battery anode consisting of a template-free 3D nanostructured Fe3O4/C composite is presented. On a full electrode basis, the nanocomposite exhibits attractive electrochemical performance including a volumetric capacity of 1064 mAh cm(-3), which significantly exceeds both the practical (≈300 mAh cm(-3)) and theoretical (837 mAh cm(-3)) capacity of a...

closed-loop supply chain network (clscn) design aims at incorporating environmental considerations into the traditional supply chain design by including recycling, disassembly and reuse activities. in a clscn, the environmental considerations can also be facilitated by resorting to environmentally friendly materials and enhancing product reuse through the design of an appropriate product recove...

One of the biggest obstacles to recycling consumer goods is the high cost of material separation. The recovered value from recycling increases as the disassembly of the discarded product is easier. For example, recovery of high-value reusable components from a car, television set or cell phone may be too labor-intensive, making recycling companies forgo that option and simply “grind the product...

The paper describes one promising method and approach for the recycling, reuse, co-resource treatment of waste photovoltaic silicon lithium battery anode graphite. Specifically, this work considers preparation nano/micron carbide (SiC) from resources. Using activated carbon as a microwave susceptor over very short timeframe, research shows that β-SiC can be successfully synthesized using sinter...

anode slimes are a by-product of the electrolytic copper refining process, which contain the precious and other important metals .in order to find a suitable method for treating these materials it is necessary to know their phase composition. for the separation of various phases from the complexmixture of copper anode. slime, the slime is leached in various steps and the residues of each step a...
