In order to gain a frame of reference for the current and future state of solid waste generation and treatment, trends pertaining to the use and disposal of plastics were analyzed to project plastic waste for the next decade. By extrapolating per capita plastic waste data, a logistic function was fitted to suggest that the annual per capita value is headed to stabilize at 94.97 thousand tons. W...

The total production of plastics is currently more than 230 million tonnes/year, which will increase to 400 million tonnes in 2020, based on a very conservative growth rate of about 5% per year [1, 2]. The increasing consumption of polymer products, in various fields, generates a large quantity of waste materials, which equates to more than 12% of the urban solid waste stream [3]. Therefore, th...

The purpose of this study is to present a practical model of strategic waste management using two SWOT models and hierarchical analysis. In this regard, using the strengths and weaknesses, the present situation and factors affecting the waste management in Tehran have been investigated. In this study, the importance of public participation in waste management using Delphi and FAHP methods was i...

In this study, an interval-parameter two-stage mixed integer linear programming (ITMILP) model is developed for supporting long-term planning of waste management activities in the City of Regina. In the ITMILP, both two-stage stochastic programming and interval linear programming are introduced into a general mixed integer linear programming framework. Uncertainties expressed as not only probab...

The environmental problems caused by the excessive use of fossil fuels for electricity generation have led to development new technologies. Microbial fuel cells constitute a technology that uses organic sources generation. This research gives novel means using Golden Berry waste as through microbial made at low cost, achieving current and voltage peaks 4.945 ± 0.150 mA 1.03 0.02 V, respectively...

Microbial fuel cells are presented as the promise of technology to generate electricity by using organic waste. In this research, molasses waste from Laredo Agroindustrial Company was used fuel, well graphite and zinc electrodes, managing build low-cost cells. It possible voltage current peaks 0.389 ± 0.021 V 1.179 0.079 mA, respectively. The showed that acid pH levels conductivity values were ...

Mixed radioactive and chemical wastes stored in tanks across the DOE complex generate hydrogen, ammonia, nitrous oxide, and nitrogen by a complex series of radiolytic and thermolytic reactions. Flammable conditions may result when these gases accumulate in the dome space of the waste tanks. A phenomenological model was developed that successfully predicts gas generation rates for many of Hanfor...
