TL;DR: An environmental eco-friendly leaching process is reported for the recovery of lithium and cobalt from the cathode active materials of spent lithium-ion batteries of mobile phones by varying the concentration of leachant, pulp density, reductant volume and temperature.

TL;DR: The survey demonstrates that the public has positive intention in participating provided the opportunities, facilities and knowledge on waste separation at source are adequately prepared by the respective local authorities, and may provide useful indicator to the waste management authorities in Malaysia.

TL;DR: The present lab-scale experimental study presents the process of leaching waste printed circuit boards (WPCBs) in order to recover gold by thioureation, and the effects of sulfuric acid concentration, hydrogen peroxide volume and temperature on the metal extraction yield were studied.

TL;DR: A novel hydrometallurgical process was proposed for selective recovery of Cu, Ag, Au and Pd from waste printed circuit boards (PCBs) by using two consecutive sulfuric acid leaching steps in the presence of H2O2 as oxidizing agents.

TL;DR: In this article, a detailed review about some essential properties of waste and recycled plastics, important for wood plastic composites production, and of research published on the effect of recycled plastics on the physical and mechanical properties of WPCs is presented.

TL;DR: In order to investigate the effect of feedstock ratios in biogas production, anaerobic co-digestions of rice straw with kitchen waste and pig manure were carried out and the optimal ratio of kitchen waste, pig manure, and rice straw was 0.4:1.

TL;DR: This paper critically reviews trends in ISR activities in selected developing and transition countries and highlights six crucial aspects from literature: social acceptance, political will, mobilisation of cooperatives, partnerships with private enterprises, management and technical skills, as well as legal protection measures.

TL;DR: This review reports the known functional and bioactive properties of hydrolysates derived from chicken by-products as well their utilisation as source of peptone in microbiological media.

TL;DR: For reliable predictive models of fermentative hydrogen production to be derived, a high level of consistency between data is strictly required, claiming for more systematic and comprehensive studies on the subject.

TL;DR: The analysis of excitation emission matrix fluorescence spectroscopy, specific ultraviolet absorbance at 254nm (SUVA254) and GC/MS showed that aromatic compounds, long-chain hydrocarbons and halohydrocarbons were abundant in the concentrated leachates.

TL;DR: The compositions, characteristics and dehalogenation methods during the pyrolysis recycling process of WEEE plastics were reviewed in this paper and can, to some degree, avoid the problem of oil value decline due to the use of catalyst, but obviously, this strategy may increase the cost of whole recycling process.

TL;DR: An advanced, flexible and multivariate Input-Output Analysis (IOA) method is proposed, which links all three pillars in IOA to construct mathematical relationships between various data points to increase the reliability of e-waste estimates compared to the approach without data processing.

TL;DR: It can be concluded that the triboelectrostatic separation of plastic waste is a promising technology, however, more research is required before it can be widely applied in industry.

TL;DR: The best codigestion BMP test has highlighted an increase of 47% in methane production respect sewage sludge digestion, and the maximum methane yield was observed for restaurant and canteens organic wastes.

TL;DR: It is found that the nature of inoculum influenced the effects of microaeration as a 21% and 10% increase in methane yield was observed when pretreatment was applied to inoculated substrates, and substrates without inoculum, respectively.

TL;DR: Information is given on the differences and similarities of current organisations distributing food to people in need as well as the political, legal, social and logistical barriers and incentives which occur with respect to this topic.

TL;DR: High odour emission from food waste compost was correlated to low pH and microbes in high-odour samples included Lactic acid bacteria and Clostridia, and for odour prevention, try high initial aeration rate and recycled compost as additive.

TL;DR: A substance flow analysis (SFA) for 31 elements including precious metals, platinum metal group elements and rare earth elements has been conducted in a solid waste incinerator with a state-of-the-art bottom ash treatment according to the Thermo-Re® concept.

TL;DR: This paper explores the current movements between Source and Destination countries, or the importers and exporters, and examines whether it is legal and why illegal traffic is still rife; how global initiatives could support a global WEEE management scheme; the recycling characteristics of the source an destination countries and whether the principle of Extended Producer Responsibility (EPR) has been established.

TL;DR: The main result is that transient economies are ready to move toward Web oriented tools for MSW management, but this opportunity is not yet well exploited in the sector.
