The Syrian civil war, which broke out in 2011, caused the displacement of more than one million refugees to Jordan. Most of them settled in the Northern Govenorates of Jordan. Due to this, the local services and infrastructures of the hosting communities, in particular the solid waste management (SWM), were put under great pressure. The aim of this study is to evaluate how the off-camp refugees impacted the SWM in the Greater Irbid Municipality (GIM; in the Irbid Governorate), both quantitatively and qualitatively. Data and results obtained from the studies carried out before the Syrian crisis are compared with data collected by the authors in 2016 using similar or comparable methodologies. Moreover, local citizen perceptions of and satisfaction with the solid waste (SW) service level were assessed. A deterioration of the SWM in GIM between 2011 and 2016 was observed in terms of service performance indicators (e.g., an increase of SW collection and transportation costs by 2.5 times and of fines for improper SW disposal by 2.2 times) and of citizens' views (a decline in SWM quality was felt by 59% of the respondents). An attempt to cope with this situation has been made in recent years with international donors mobilizing efforts and resources to enable municipalities to meet the growing demand in basic SW services. There is however, still much to be done.

The resource utilization of municipal solid waste incineration fly ash (MSWI FA) has been widely concerned at present. The chlorine removal from MSWI FA is of great significance for controlling environmental risk and improving materials properties in the process of its resource utilization. This work specifically proposes to divide the chlorine in MSWI FA into inorganic chloride and organic chloride.

We explore the application of machine learning (ML) techniques to forecast door-to-door waste collection, addressing the challenges in municipal solid waste (MSW) management. ML models offer a promising solution to optimize waste collection operations, especially amid growing urban populations and evolving waste generation rates. Leveraging comprehensive data from a northeastern Italian municipality, including various waste types, our study investigates ML algorithms' efficacy in predicting household waste collection requirements.

Electronic address:
Despite advances in anaerobic digestion (AD), full-scale implementation faces significant challenges, particularly during the start-up phase, where inoculum selection is crucial. This study examines the impact of inoculum choice on the operational and economic performance of thermophilic digesters during the start-up phase. Methanogenic reactors R3 and R4 were inoculated with digested sludge (DiS) and diluted sewage sludge (DSS), respectively, and fed with hydrolyzed source-sorted organic fraction of municipal solid waste (SS-OFMSW) and thickened sewage sludge, which were processed in R1 and R2, serving as acidogenic reactors.

Polyethylene terephthalate (PET) has been widely used in plastic products, leading to massive PET waste accumulation in ecosystems worldwide. Efforts to find greener processes for dealing with post-consumer PET waste led to the discovery of PET-degrading enzymes such as PETase (PETase). studies have provided valuable contributions to this field, shedding light on the catalytic mechanisms and substrate interactions in many PET hydrolase enzymes.

Given the current construction waste accumulation problem, to utilize the resource of red brick solid waste, construction waste red brick was used as a concrete coarse aggregate combined with polypropylene fiber to prepare PPF (polypropylene fiber)-reinforced recycled brick aggregate concrete. Through a cube compression test, axial compression test, and four-point bending test of 15 groups of specimens, the influences of the aggregate replacement rate of recycled brick and the PPF volume on the mechanical properties of recycled brick aggregate concrete reinforced by PPF were studied, and a strength parameter calculation formula was constructed and modified based on the above. Finally, combined with a life cycle assessment (LCA), the carbon emissions of raw materials were analyzed and evaluated.
