Municipal solid waste (MSW) is the natural result of human activities. MSW generation modeling is major significant in municipal solid waste management system planning. Predicting the amount of generated waste is difficult task because it is affect by various parameters. In this research, Artificial Neural Network (ANN) was trained and tested to weekly waste generation (WWG) model in Sari’s cit...

M ore than 1 billion people already suffer from chronic hunger, and the world population is expected to grow from 6.8 billion people to about 9 billion by 2050 [1]. The Food and Agriculture Organization of the United Nations (FAO) anticipates that food requirements will have to increase by between 70 and 100% to both alleviate existing hunger and malnutrition and feed the additional 2 billion p...

Environmental problems related to heavy metals have a long history. Heavy metals have toxic properties, leading to adverse effects on human and ecosystem health even in small doses. Another problem-causing property is their non-degradability: once they enter the environment they will remain there for a long time. Metals tend to accumulate in soils and sediments, with immobilisation due only to ...

Understanding the factors influencing recycling behaviour can lead to better and more effective recycling programs in a community. The goal of this study was to examine factors associated with household waste behaviours in the context of the theory of planned behaviour (TPB) among a community sample of Iranians that included data collection at time 1 and at follow-up one year later at time 2. S...

Food waste is a global problem. When discarded into landfills through traditional municipal solid disposal, food costly, contributes to greenhouse gas emissions, and highlights disparities of insecurity. Government retail campaigns overwhelmingly target consumers as responsible actors for tackling prevention, reduction, recovery activities. Multinational enterprises (MNEs), however, play signif...

Electrical and electronic products have become an integral part of the current economy and, with the development of newer technologies, the life span of these products are getting shorter. As a consequence, the volume of electronic waste is increasing drastically around the globe. With the implementation of new rules, regulations, and policies by the government, the landfilling of electronic wa...

The selection of an appropriate “optimal” recycling alternative has to take into consideration both the ecological and economic effects of the entire life-cycle. The aim of this paper is to compare different waste management systems by means of a life-cycle assessment (LCA) and a cost comparison. The analysis uses data regarding the amount of household waste generated, collected and treated in ...
