TL;DR: It is crucial that proper regulations are proposed and implemented in order to reduce the occurrence of microplastics in the aquatic environment and without appropriate law and regulations, microplastic pollution will eventually threaten human livelihood.

TL;DR: This review article focuses on the various sources attributed to marine microplastics, the latest international, regional and national countermeasures to combat marine litter, as well as the status quo of microplastic pollution, legislation and regulations in China, and provides improving proposals/solutions on key research gaps, governance and management for future environmental control and policymaking in China.

TL;DR: In Italy, reduction in both waste arisings and the associated costs could be realised through various means, including improved waste segregation, and linking the TARI tax to waste generation.

TL;DR: In this paper, the authors examined the French national program for managing post-consumer textiles and clothing through a case study research and highlighted the benefits of using an extended producer responsibility (EPR) policy and provided interesting insights about the challenges faced by the textiles waste sector.

TL;DR: This route successfully upgrades PR from waste tires to the high value-added CCB and greatly increases the overall efficiency of the waste tire pyrolysis industry.

TL;DR: A comprehensive review of evaluation tools based on life cycle thinking, as applied to waste-to-energy, is proposed and some recommendations for further research are summarised.

TL;DR: This research concludes that the most suitable waste-to-energy technology for Oman, on the basis of the identified criteria, is anaerobic digestion followed by fermentation and incineration, which will help to reduce the amount of waste, greenhouse gas emissions and developing and maintaining costs of landfills.

TL;DR: The present e-waste management needs to be more focused on environmentally sound management, by more active support from all the participants involved in the e-Waste flow chain in India.

TL;DR: Leaching mechanisms of arsenic, chromium, lead, and zinc from cement and fly ash stabilised soils were investigated in the laboratory and suggested that chemical compounds on fly ash surfaces can control the pH of the fly ash and soil leachant.

TL;DR: The research conducted revealed that the MSWM of La Paz is not efficient with regard to collection, recycling, financial sustainability, and equity of the service, and the main strengths and weak points for implementing a sustainable MSWM are analyzed.

TL;DR: The results showed the relevance of considering social aspects in municipal solid waste management and isolated inequality as an important factor in planning and that inequality must be used as a complementary factor to income, rather than being used exclusively.

TL;DR: The study concluded that the bulk of the soil-like material from aged municipal solid waste landfills can be used as cover material for landfilling at the same site, however, some treatment before it can be re-used in other geotechnical applications.

TL;DR: The survey results support the experience of establishing a community-based semi-official picker organizational framework accompanied by relevant laws, regulations, and preferential policies that would improve the resource recovery rate and pickers’ living and working conditions in order to achieve more effective and hazard-free MSW resource utilization.

TL;DR: The analytical hierarchal process approach has been used and a survey from Pakistan’s largest city has been considered to rank the most appropriate criteria that is necessary to select the supplier, especially in a developing country like Pakistan.

TL;DR: The main findings suggest that cost and employee awareness were the most significant barriers to more sustainable waste management, and provide an empirical basis for multi-criteria evaluation of the literature.

TL;DR: Algal biomass is a good source for biogas production, although further research is needed to increaseBiogas yield and quality, according to the main purpose of this study.

TL;DR: Only the acidic pretreatment (HCl) was found to significantly increase methane generation and the methane yield of OFI biomass, and modelling of the cumulated methane production by the Gompertz modified equation was successful and aided in understanding kinetic advantages linked to some of the pretreatments.

TL;DR: This study proposes a methodology for siting sanitary landfills and optimising the transport of municipal solid waste for a locality in the state of São Paulo, Brazil and uses the Mixed-Integer Quadratic Programming mathematical model to minimise the costs of transporting municipalSolid waste and operating sanitaryLandfill.

TL;DR: The results show that a geographic information system is an essential tool in the planning of municipal construction and demolition waste management, in order to facilitate the spatial analysis and control the generation, sorting, collection, transportation, and final destination of construction and demolishing waste, increasing the rate of recovery and recycling of materials.

TL;DR: The results showed that mercury use is still prevalent among small-scale gold miners in the Philippines, and the most prevalent form of mercury in the mine tailings was elemental/amalgamated mercury, followed by water soluble, exchangeable, organic and strongly bound phases.

TL;DR: Composting-landfilling was the most preferred option, leading to a reduction in global warming potential by 79% and a slight decrease in freshwater ecotoxicity by 64%.

TL;DR: The results demonstrate that readily biodegradable substrates, such as food residue biomass, can be effectively used for enhanced bioelectricity harvesting in a microbial fuel cell.

TL;DR: In this paper, the safe disposal of fly ash generated by coal-based thermal power plants continues to pose significant challenges around the world and in India in particular, and a green structural concrete with 80% cement is proposed.

TL;DR: The evaluation showed that greater efforts should be made to exploit the energy potential of organic fraction, together with higher recycling rates, to move towards lower environmental impacts associated with municipal solid waste management.

TL;DR: This mini-review paper describes the panorama of waste management practices in Botswana and provides information to competent authorities responsible for waste management and to researchers to develop and implement an effective waste management system.

TL;DR: Overall the results give promise for a valorisation route of this waste material in the field of ground improvement, based on plasticity characteristics, unconfined compressive strength (UCS), water retention and volumetric stability.

TL;DR: The economic income level and the seasonal variation on the collection and the purity of light-packaging waste to determine actions to improve the waste management plan of a town is analyzed.

TL;DR: The use of PE-g-MA at 2.5 wt% as a compatibilizer during reactive extrusion of the multilayer films waste has showed the best result for production of the respective recycled LDPE/PA6 blends.

TL;DR: The project ‘Electric vehicle recycling 2020 – key component power electronics’ developed an optimised recycling route for recycling power electronics modules from EVs which is also practicable in series production and can be implemented using standardised technology.
