“…Moreover, during the collection of USW, greenhouse gases (GHGs) are produced and released into the atmosphere, although emissions levels depend on many factors, such as (i) the collection system, (ii) the frequency of USW collection, and (iii) the type of fuel used by collection vehicles [26][27][28][29]. Transportation is an essential factor that should be considered in studies on GHG emissions within the waste management sector [30,31].…”

Collecting urban solid waste (USW) is a critical and essential phase for proper waste management and valorization. To date, many data are available for large cities, but few studies have focused on low-density areas, such as mountainous regions. Considering this lack in the literature, this study aimed to compare two separate waste collection systems in two mountainous valleys in terms of effectiveness and GHG emissions. In the first scenario, a mixed collection system (door-to-door + centers) was used, while in the other, waste was separately collected by a full door-to-door system. The results suggested that the full door-to-door system achieved better performance than the mixed collection system (door-to-door + centers), with a fraction of separate waste collection compared to the unit equals (0.84 ± 0.01 vs. 0.79 ± 0.02). Moreover, the full door-to-door system represented the best option for collecting separate waste in mountainous areas in terms of GHG emissions, with 11.21 kgCO2, eq twaste−1 emitted vs. 15.62 kgCO2, eq twaste−1 in the case of the mixed system. Despite utilities emitting a higher amount of GHGs in the door-to-door scenario (4.66 kgCO2, eq inh−1 y−1), they were fully compensated for by the low GHG emissions from citizens in the mixed scenario (1.77 kgCO2, eq inh−1 y−1 vs. 6.65 kgCO2, eq inh−1 y−1). Given the low amount of data on this topic, this work could be considered as a pioneer study of waste management in mountainous areas by comparing the results of two systems regarding effectiveness and GHG emissions. The outcomes of this study could be helpful for waste utilities, institutional agencies, and local communities and also serve as a tool for decision-making in the case of comparing the different options for USW collection systems.

This chapter addresses the critical need for enhancing energy efficiency and economic rationale in municipal solid waste (MSW) management, focusing on collection and transportation – the costliest segments. Utilizing digital technologies, including GIS, IoT, and data analytics, the authors develop a practical methodology for optimizing waste collection and transportation processes, particularly in developing countries. The study tests this methodology in 11 Serbian municipalities, demonstrating significant travel distance and time reductions through optimized routes compared to existing ones. Reduction in total distance travelled ranges from 5.1 to 15.1%, depending on the municipality. These optimizations lead to reduced energy consumption, environmental preservation, improved service quality, and the promotion of circular economy practices. This chapter highlights the importance of digital technologies in MSW management, offering a model that can be adapted to various municipal sizes and contexts, thus presenting a scalable and sustainable approach to modern waste management challenges.
