Introduction
• Uncontrolled urban expansion and the massive increase in urban populations have led to a vast amount of consumption and
different types of waste generation over the past years.
• In 2012, various cities in the world generated 1.3 billion tons of solid waste, equivalent to 1.2 kg per person per day.
• It is expected that annual waste generation rate will reach 2.2 billion tons by 2025, accordingly.
Economical aspect:
• This amount of waste generation definitely leads to an increase in the necessary funds for collection, transportation and
disposal operations, which contains 75%-80% of Urban Solid Waste Management (USWM) costs (Tirkolaee et al., 2018).
Environmental and health aspect:
• These operational processes must be done within the shortest possible time to prevent the spread of potential contamination and infections. • On the other hand, there is now a global force on GHG reduction, which should be considered in USWM too.
Uncertainty:
• The exact amount of generated waste is always unknown in each urban area due to its uncertain nature. • In fact, each area may have a lower and an upper bound for the amount of waste according to its minimum and maximum
values in a given time period.
