Ancient trash mounds unravel urban collapse a century before the end of Byzantine hegemony in the southern Levant
The historic event of the Late Antique Little Ice Age (LALIA) was recently identified in dozens of natural and geological climate proxies of the northern hemisphere. Although this climatic downturn was proposed as a major cause for pandemic and extensive societal upheavals in the sixth–seventh centuries CE, archaeological evidence for the magnitude of societal response to this event is sparse. This study uses ancient trash mounds as a type of proxy for identifying societal crisis in the urban domain, and employs multidisciplinary investigations to establish the terminal date of organized trash collection and high-level municipal functioning on a city-wide scale. Survey, excavation, sediment analysis, and geographic information system assessment of mound volume were conducted on a series of mounds surrounding the Byzantine urban settlement of Elusa in the Negev Desert. These reveal the massive collection and dumping of domestic and construction waste over time on the city edges. Carbon dating of charred seeds and charcoal fragments combined with ceramic analysis establish the end date of orchestrated trash removal near the mid-sixth century, coinciding closely with the beginning of the LALIA event and outbreak of the Justinian Plague in the year 541. This evidence for societal decline during the sixth century ties with other arguments for urban dysfunction across the Byzantine Levant at this time. We demonstrate the utility of trash mounds as sensitive proxies of social response and unravel the time–space dynamics of urban collapse, suggesting diminished resilience to rapid climate change in the frontier Negev region of the empire.

Contamination of fabric surface by the particles woven from the cotton waste open end rotor yarn
The study investigated and analyzed the contamination of the fabric surface due to cotton waste yarn woven into the weft. The impact of cotton waste proportion and cleaning methods on open-end rotor yarn quality, using blends from 100 to 0% cotton waste mixed with virgin cotton fibers were investigated. The study proves that cotton waste can be effectively incorporated into yarn production without significantly compromising fabric properties, supporting the sustainable use of recycled fibers. The innovative cleaning channel W increases fiber yield but also raises contamination levels, leading to a higher number of detected impurities on the fabric surface. The classification method for dust and trash particles significantly affects the contamination evaluation, though contamination trends remain consistent. The classification of dust and trash particles by the maximal Ferret’s diameter is preferred based on the obtained outputs from the realized experiment. Additionally, while the size of dust particles decreases as the cotton waste proportion decreases, trash particle size is unaffected by the cleaning channel or waste ratio in the weft yarn. In the case of the binary portion, contaminant levels decrease as cotton waste content in weft yarns is reduced, with the lowest found in cleaning channel A, followed by C and W. Surprisingly, dust and trash particles contribute to the binary portion equally. It leads to the recommendation connected with optimizing fabric quality, the final treatment should focus mainly on eliminating the visual impact of larger contaminants. The reason is that smaller particles can be mostly removed during pretreatment because they are not firmly fixed in a woven structure. The results also highlight the link between fabric contamination and potential health risks from respirable dust particles in the workplace, underscoring the need for effective control during processing to protect workers and ensure stable production not only in weaving but also in the following processes.

Plastic waste and recycling : environmental impact, societal issues, prevention, and solutions
Plastic Waste and Recycling: Environmental Impact, Societal Issues, Prevention, and Solutions begins with an introduction to the different types of plastic materials, their uses, and the concepts of reduce, reuse and recycle before examining plastic types, chemistry and degradation patterns that are organized by non-degradable plastic, degradable and biodegradable plastics, biopolymers and bioplastics. Other sections cover current challenges relating to plastic waste, explain the sources of waste and their routes into the environment, and provide systematic coverage of plastic waste treatment methods, including mechanical processing, monomerization, blast furnace feedstocks, gasification, thermal recycling, and conversion to fuel. This is an essential guide for anyone involved in plastic waste or recycling, including researchers and advanced students across plastics engineering, polymer science, polymer chemistry, environmental science, and sustainable materials.

Intelligent Trash Level Detection for Sustainable Urban Waste Management
This paper introduces an advanced trash bin fill ratio detection system, addressing the challenges of municipal solid waste management. Utilising the ESP32 CAM module, the system captures and transmits bin images via the ESP MESH protocol, enhancing waste management efficiency. The hardware relies on sustainable energy sources, including a photovoltaic cell and LiPo battery, ensuring continuous operation. On the software front, a client-server architecture is employed. The client-side captures images, while the server-side processes these images using a Python script and SQL database to determine bin fill levels. This innovative approach offers a scalable, cost-effective solution for improving urban waste collection and management.

\Lolo,\ by Luis Arriola Ayala. Translation by Megan Saltzman
INTRODUCTION: “Lolo” is one of the eight stories from the book Otosan (2015). Written by Peruvian journalist Luis Arriola Ayala, this book gives visibility to postcolonial, transnational migrant experiences. “Lolo” tells the story of an encounter between two undocumented workers, a young Peruvian and an old Filipino, in a garbage incineration plant in Tokyo. Despite the alienating situation and not being able to speak the same language, the two manage to find temporary companionship and ways to resist. This short story is based on the author’s personal experiences working in Japanese factories. KEYWORDS: Tokyo, Japan, Peru, Philippines, trash, recycling, material, postcolonialism, immigration, solidarity
