TL;DR: In this paper , the authors employed regression analysis and material flow analysis approaches to ensure a cross-comparability of waste generation data and found that almost one-third of the total waste generated is not collected, and most of what is collected is not treated accordingly to current ideas of sound management.

TL;DR: In this paper , landfill leachate (LL) was used as an aqueous medium during hydrothermal carbonisation (HTC) of food waste to produce hydrochar (FWH-LL-C).

TL;DR: Li et al. as mentioned in this paper compared the impact of two battery replacement methods (buying a new vehicle or replacing the battery) on future EOL EV production, and predicted the difference in the amount of EOL EVs battery production under two probability functions (normal and Weibull's distributions).

TL;DR: In this paper , a systematic review and content analysis to categorise all types of waste management (WM) during the COVID-19 pandemic was conducted to accomplish a well understanding of the relation between the CoVID-2019 pandemic and its impacts on WM within the literature.

TL;DR: The approach of physical recycling methods described in this mini-review helps to maintain the value of polymer materials in the value chain allowing the reuse in the original or similar application as mentioned in this paper .

TL;DR: In this article , a mini-review focused on green gas derived from biomass called biomethane, which appears to be strategic in the face of soaring energy costs, is presented.

TL;DR: In this article , a suite of novel simulations investigated the influence of key parameters on bed-cooling time and found that cooling time decreased nearly linearly with decreases of volume-averaged bed temperature and bed bulk density.

TL;DR: In this article , the authors describe how industrial symbiosis is reposed in studies dealing with the Brazilian context, based on a systematic literature review in the Scopus and Web of Science databases, relying on the Prisma method and a research protocol.

TL;DR: In this article , the authors identify the validity of this domain both in the global and native research community by conducting a detailed review using bibliometric analysis and content analysis, and provide the struts for a circular and sustainable supply chain for processed seafood in developing economies.

TL;DR: In this paper , a qualitative System Dynamics model of the urban system was designed to find the root causes and leverage points for interventions in waste management problems in developing countries, and a new taxonomy was proposed to classify cities with regard to the effect and delay in their urban processes.

TL;DR: In this paper , a chance-constrained multi-compartment electric vehicle Routing Problem (CCMCEVRP) is introduced and the corresponding mathematical formulation is established, and a diversity-enhanced particle swarm optimisation with neighbourhood search and simulated annealing (DNSPSOSA) is proposed to solve this problem, and effectiveness of the proposed algorithms is verified by extensive numerical experiments on the newly generated instances.

TL;DR: In this article , the authors discuss the evolution of waste to energy incineration and highlight the currently used and advanced incineration technologies, including combined incineration with other energy, for instance, hydrogen production, coal and solar energy.

TL;DR: In this article , the authors present a state-of-the-art overview to compare worldwide studies and the results and implement a comprehensive survey in Portugal (n = 454 respondents).

TL;DR: In this paper , the authors combined particle size reduction with Fe3O4 nanoparticles to investigate their influence on biogas and methane yields from anaerobic digestion of Arachis hypogea shells.

TL;DR: In this paper , a systematic review of 111 studies published in environmental journals indexed in the Web of Science was carried out to identify the environmental policies that would facilitate an adequate treatment of the waste generated by the pandemic.

TL;DR: In this article , a mini-review aims to review current end-of-life (EoL) management practices in the large-scale wind industry for countries with established EoL standards as well as those with less mature regulations.

TL;DR: In this paper , the authors describe the catalytic cracking of low-density polyethylene over attapulgite clay and iron substituted tungstophosphate/attapulgurite clay composite materials to evaluate their suitability and performance for recycling of plastic waste into liquid fuel, and the prepared catalysts enhanced the yield of liquid fuel (hydrocarbons) produced in cracking process.

TL;DR: In this paper , the authors evaluate various approaches for end-of-life management of wind turbine blades emphasizing on fiber recovery, including thermal treatment and chemical treatments and their economic and environmental comparisons.

TL;DR: In this paper , the authors assessed the process and functionalities of livestock waste generated from the piggery farm and their combinations with other by-products such as biochar and ash in comparison with mineral fertilization as sources of nitrogen applied in agricultural soil.

TL;DR: In this paper , the pyrolysis of spent coffee grounds (SCG) and polymers was examined as a waste treatment option for energy recovery and carbon sequestration, with yields of 22, 33, and 45%, respectively.
