Waste management has emerged as a critical global challenge due to the increasing amounts of waste generated, coupled with the environmental and health hazards associated with traditional landfill disposal methods. This paper delves into the paradigm shift occurring in waste management, highlighting the transition from conventional landfilling to innovative and sustainable techniques. The abstract reviews the current state of waste management, emphasizing the shortcomings of landfills in terms of resource utilization, pollution prevention, and space constraints. It then introduces various modern waste management techniques that prioritize waste reduction, recycling, and energy recovery. Techniques such as source separation, composting, anaerobic digestion, and waste-to-energy technologies are discussed, shedding light on their benefits, challenges, and potential applications. Furthermore, the abstract explores the role of advanced technologies, including artificial intelligence, robotics, and data analytics, in optimizing waste sorting, collection, and processing. These technologies enhance efficiency, reduce contamination, and improve overall waste management processes.

As the world grapples with escalating waste generation and resource depletion, advanced recycling solutions offer a glimmer of hope for a sustainable future. This article explores the transformative potential of advanced recycling technologies and their role in building a circular economy. From chemical recycling and innovative sorting techniques to digitalization and public awareness, these solutions are paving the way towards efficient resource recovery, waste reduction, and environmental preservation. By embracing advanced recycling solutions, we can reshape the way we manage and value waste, moving away from the linear "take-make-dispose" model and towards a more sustainable and regenerative approach.

Packaging contaminated with Portland cement, which is not easily recyclable and has a high cost and environmental impact for processing, is discarded in large quantities by the relevant civil construction sector. Using available literature, a method was developed to transform packages contaminated with Portland cement into a macroscopic by-product, through hydrolysis in sodium hydroxide (NaOH). The results demonstrate that the process can be sustainable for the disposal of bags contaminated with cement, which also showed an average loss of almost 0.1% of Portland cement per bag. Among other characteristics, the by-product obtained has an average density of 0.45 g/cm³ and most of it has a granulometry of less than 0.5 mm, facilitating handling and enabling reuse. This method is capable of including almost 6,000 bags of cement in a volume of 1 m³.
