Waste management for smart cities

The collection and transportation of waste are one of the most important management problems of cities. These very costly collection and transport activities can be seen as areas of optimization. Garbage collection increases the “autonomy” of garbage collection points, minimizing the total investment cost and purchasing cost of each bin. Autonomy relates to the number of days a Trash Point can wait between two consecutive visits by the collection vehicle (to empty the bins) (Rossit et al., 2019). For this reason, determining the garbage collection points in urban scenarios is another WM problem that needs to be solved. Waste collection is a daily task that requires planning truck routes in urban areas to avoid high fuel costs and reduce the number of round trips, taking into account environmental, economic and social factors (Khoa et al., 2020).

With increase in the global population and the rising demand for food and other essentials, there has been a rise in the amount of waste being generated daily by each household. This waste is ultimately thrown into municipal waste collection centers from where it is collected by the area municipalities to be further thrown into the landfills and dumps. However, either due to resource crunch or inefficient infrastructure, not all of this waste gets collected and transported to the final dumpsites. If at this stage the management and disposal of waste are improperly done, it can cause serious impacts on health and problems to the surrounding environment. We have seen this problem in the chemically sensitive who are exposed to the air around waste pits.
Solid Waste Infrastructure

The environmental and health impacts of poor waste management can be grave. Waste decomposition in landfills generates methane, a very potent greenhouse gas. Littering and leaching can lead to extended water and soil contamination, affecting habitats and food chains. The absence of waste collection on the other hand, i.e., the accumulation of uncollected waste in residential areas, may cause public health problems such as respiratory ailments, diarrhea, dengue fever, chemical poisoning through chemical inhalation, cancer, low birth weight, congenital malformations, etc. Uncollected waste may also interrupt stormwater flows and potentially cause flooding by clogging natural and artificial drainage systems.

A typical collection strategy of COVID-related waste from various sources is depicted in Figure 2. Such waste collection strategies must be made mandatory for waste management systems in urban as well as rural areas. Appropriate and efficient waste collection systems provide a firm base for downstream waste handling and disposal. Improper waste collection methods and wrong practices shall not only make it difficult to handle the waste but also provide a potential health risk and a hazard of further spread of the virus. In this context, the source segregation or source treatment becomes very vital.

As discussed above, separating a specific waste type from the landfill stream and treating it differently may cause additional GHG emissions from the alternative treatment. For example, where the alternative treatment requires additional waste collection trips, the transport emissions may be greater than those of landfilling that material. However, in some circumstances, waste separation and reductions in the waste to landfill provides GHG benefits.

Selective Pickups with Pricing selects only profitable collection points to visit. Waste Collection (waste management) includes waste reuse, prevention and recycling. End-of-life Goods Collection is useful for remanufacturing. Finally, the Simultaneous Distribution and Collection addresses applied modeling in the context of reverse logistics (Demir et al., 2014b; Lin et al., 2014; Soleimani et al., 2018).
