The circular economy (CE) is an evolving economic and sustainable development model. In this new environment, companies face a more dynamic, uncertain, complex market environment. These challenges arise from material closed-loop flows necessary for functioning CE. It important to build flexibility capabilities into supply chains address CE operational challenges. Building capability needs occur without incurring performance degradation, increasing costs, or compromising product quality....
Developing platinum catalysts highly active for hydrocarbon combustion at low temperatures is crucial but yet challenging, since may convert into inert PtOx in oxidizing atmospheres and deactivates during catalytic combustion. In this article, a Pt@TiOx/TiO2 catalyst with nanoparticles decorated by amorphous TiOx overlayers was synthesized via strong metal–support interaction (SMSI)-related strategy. The Pt-TiOx electronic stabilized reactive Pt0 sites reactions, resulting outstanding...
Electronic waste (e-waste) is one of the fastest growing streams around world, and mobile phones contribute a major portion this waste, in terms number units. Thus, order to fully discover constituent materials systematically evaluate recovery potentials for phones, we dismantled 20 manufactured between 2001 2015, into 7 main parts. We wanted determine all valuable precious metals these devices compare differences cellular smart phones. The results show that were evolving smaller sizes 2012,...
Owing to increasing environmental concerns, disassembly has become an important step in value recovery from end-of-life (EoL) products. As one of the prevalent electronic devices, smartphones are especially challenging manage at end life. They have a diverse internal structure that leads difficulties modeling and developing general plans for disassembly. Given this background, improved method uses Q-learning algorithm is proposed optimize sequence EoL smartphones. A constraint relationship...
Pyrolysis technology, as a method for recycling waste polystyrenes (WPs), is widely regarded an effective means to achieve the high value reutilization of WPs due its environmental friendliness and renewability resources used. However, in conventional pyrolysis process WPs, relatively temperatures are often required induce pyrolysis. This not only consumes significant amount energy but also leads complex variable product compositions temperatures. Therefore, there urgent need develop...
E-waste problem is a worldwide conundrum. China, as an important production, consumption and export country of electrical electronic equipments face great pressure on e-waste recycling. This paper introduced the current situations reviewed various technologies different scale facilities recycling existed in China. The challenges for government, original equipment manufacturers recyclers were analyzed based China global. At last corresponding countermeasures which have been will be...
The paper introduces the Energy-related Products(ErP)directive and its late evolution. Both general particular eco-design requirements of a refrigerator are presented. criteria standby/off listed as well. assumptions made for modeling product source database put forward. There 11 factors environmental impacts used in evaluation software EIME. impact manufacturing, distribution, use end life is analyzed according to certain refrigerator. results show that three significant, which electricity...
The wide application of plastic products had led to a large amount waste plastics, which brought serious environmental pollution problems. Although separation is the first step recycling, injection separating device still not fully optimized. In this paper, influences nozzle outlet diameter, contraction ratio, length section, total nozzle, and distance between two nozzles on were systematically simulated analyzed using computational fluid dynamics (CFD) software. Based Witozinsky curve,...
Numerous jets can be generated simultaneously on a nozzle by needleless melt electrospinning technology which has the advantages of solvent-free residues and environmental friendliness; potential industrial application prospects. In this paper, linear annular tip was taken as research object, high-speed image acquisition generation distribution process carried out compared with that straight-line nozzle. The results showed repulsive force between caused slight adjustment in position free...
Waste mobile phones (WMPs), as a type of electronic waste, must be properly disposed of, so not to pollute the environment. WMPs should non-destructively dismantled, recycle useful resources and produce considerable economic benefits, they contain many rare metals. Dismantling equipment, though, is hard adapt multiple types phones, since models are produced each year. A smart classification dismantling method for thus proposed here. The feature attributes different collected, weight phone...
Disassembly is one of the most important steps throughout life cycles many waste electronics. Since mobile phones are popular electronic devices but have a short service life, they largest contributors to fastest-growing streams worldwide, and problems recycling smartphones urgently need be properly resolved. To improve disassembly efficiency smartphones, it essential pay attention process generation. In this study, an efficient generation method proposed provide solution for improving large...
Disassembly is an inevitable step in the recovery of valuable materials from end-of-life (EoL) mobile phones. Although a Hybrid Graph one prevalent method for disassembly modeling, it cannot accurately describe subassembly disassembling process. In this paper, improved hybrid graph model (IDHGM) selective sequence planning proposed limitations process EoL The containment, exclusion, and are considered view close connection phone parts occurrence interlocking between parts. Based on different...
The volume of used smartphones continues to increase with the development smartphone industry; carbon emissions continue rise; and resource waste is serious. To solve these problems, a dismantling industry has been developed. Expert research found that lack systematic fault detection process affects efficiency disassembly. A method for disassembly re-assembly based on fuzzy set tree analysis designed here. This transforms traditional manual into computing database collaborative arranges...
