This paper considers a truck scheduling problem in the context of solid waste collection in Porto Alegre, Brazil. The problem consists of designing ``good" daily truck schedules over a set of previously defined collection trips, on which the trucks collect the solid waste in fixed routes and empty the loads in one of the several operational recycling facilities in the system. The main objective...

Introduction: In Tehran with a population of 9 million currently, about 2.5 million tons municipal solid waste have been producing annually. Materials and Models: In this study by using Life Cycle Assessment (LCA) model an optimal system of waste management of Tehran was recommended. Based on the quantity and quality of waste in Tehran in 2013 and facilities, three scenarios were selected. Fir...

Waste is a byproduct of human life. Nowadays, municipal solid waste is being produced in excessive amounts and in this way, both developing and developed countries are facing challenges regarding generation of waste. Economic development, urbanization and improved living standards in cities have contributed to increase in the amount and complexity of solid waste produced. The present stud...

This study concentrates on designing a medical waste management system with a hierarchical structure, including a local government and a waste management planner. The upper-level seeks to design and control the waste management facilities by minimizing the environmental risks related to the disposal of medical waste. While the lower-level model is to determine the waste collection plans by only...

The ultimate responsibility for the collection and disposal of municipal solid waste rests with local government. As regional planning developed, more counties and states assumed some or all of this re­ sponsibility. The Federal Government has not, to date, provided the broad financial support for solid waste systems now available for municipal waste water systems. Their participation has been ...
