This paper examines a Waste Management Organisation's (WMO) pricing options to implement the Pareto-efficient allocation in an economy where materials are first extracted, then used for producing a consumption good and finally recycled or landfilled. The WMO is established by the producers who are responsible for the proper disposal of consumption waste which consists of a mix of materials. Tha...

We report the use of a simple yet highly effective magnetite-waste tea composite to remove lead(II) (Pb(2+)) ions from water. Magnetite-waste tea composites were dispersed in four different types of water-deionized (DI), artificial rainwater, artificial groundwater and artificial freshwater-that mimic actual environmental conditions. The water samples had varying initial concentrations (0.16-5....

Recently, the subject of “green chemistry” has received considerable attention from academic and industrial researchers alike.1 While the central tenets of waste reduction, process economy and elimination of risks and hazards have long been embraced by industrial process chemists, the current focus on green chemistry concerns has led to renewed appreciation for the importance of these topics. T...

Nowadays stakeholders and public awareness have increased the pressure on companies for environmental issues. Thus, green supply chain management (GSCM) seems vital for companies' environmental compliance and business growth. Companies continuously seek novel ideas and methods, that can enable them to obtain and/or maintain environmental sustainability. Greening the supply chain is one such...

Introduction: Current energy sources are coming to end and one of the main priorities of the country’s management is the energy recovery from renewable energy. Considerable quantity of municipal solid waste (MSW) is one of the most serious urban pollution sources. Impact assessment matrix is a new and fast tool for Environmental Impact Assessment (EIA). Materials and Methods: In this regard, r...

Transmissible spongiform encephalopathies (TSEs, prion diseases) are a class of fatal neurodegenerative diseases affecting a variety of mammalian species including humans. A misfolded form of the prion protein (PrP(TSE)) is the major, if not sole, component of the infectious agent RecentTSE outbreaks in domesticated and wild animal populations have created the need for safe and effective dispos...
