Municipal solid waste management considering NGO’s role in consumer environmental awareness and government regulations for air pollution

PurposeThe purpose of this study is twofold: first, to examine the role of non-governmental organizations (NGOs) in increasing customer environmental awareness (CEA) to decrease the municipal solid waste (MSW), and secondly, to examine the effect of government policies in the amount of air pollution caused by transfer stations (TSs).Design/methodology/approachThis study proposes a mixed-integer nonlinear programming model.
