The organic dyes directly pollute the soil, water, plants and all living systems in the environment. In the present investigation, adsorption of brilliant green dye on silica from aqueous solution was studied. The dye adsorption mechanism was studied on the basic surface of silica. The adsorption parameters were optimized to maximum adsorption. The adsorption mechanism of brilliant green on sil...

Adsorption of malachite green (MG) from aqueous solution onto treated ginger waste (TGW) was investigated by batch and column methods. The effect of various factors such as initial dye concentration, contact time, pH and temperature were studied. The maximum adsorption of MG was observed at pH 9. Langmuir and Freundlich isotherms were employed to describe the MG adsorption equilibrium. The mono...

In this paper we discuss the problem of efficient use of Content Management Systems in the development of a web site, and we propose a new approach towards the definition of a Green Content Management System (GCMS). Our GCMS distinguishes between pages which contain dynamic data and pages which are not supposed to change frequently. This second kind of documents is generated, off-line, every ti...

Due to the rising trend of urbanization along with overconsumption of non-recyclable resources, the volume of municipal solid waste is increasing every day. An efficient, cost effective and environment friendly solution for real time bin statusmonitoring, collection and transportation of municipal solid waste is still a major challenge to the local municipal authorities. This research proposes ...

Environmental issues have become a topical subject in recent years. Numerous recycling resources can be found in our living environment, such as fallen leaves, wood chips, recovered iron powder, waste newspaper, waste concrete, reservoir silt, etc., which are utilizable waste materials. Related regulations stipulate that the waste blending ratio of recycling green building materials should be h...

The purpose of this work is the study of the use of waste glass obtained from crushed containers and building demolition as partial Portland cement replacement in mortar and concrete. For this, the waste glass must have the characteristics of pozzolanic material. In this context, a study of the pozzolanic activity of two types of glass clear and green coloured, with varying the particle size of...

Electronic waste (e-waste) is a growing occupational and environmental health issue around the globe. E-waste recycling is a green industry of emerging importance, especially in low-and middle-income countries where much of this recycling work is performed, and where many people's livelihoods depend on this work. The occupational health hazards of e-waste recycling have not been adequately expl...

In this study, alkali silica reaction (ASR) expansion and strength characteristics of mortar containing waste glasses are analyzed in terms of waste glass content and glass color. Three different colors of waste glasses (white, green and brown) are replaced with sand at ratios of 10%, 30% and 100% by weight. The mixtures used in this study did not show a considerable ASR expansion. All batches ...

This paper aims to propose a conceptual model to analyse the influence of lean, resilient and green supply chain management practices on supply chain sustainability. A deductive research approach was used to develop a conceptual model from the literature review. The SCM practices focused in this study are: waste elimination, Total Quality Management, just-in-time; supply chain risk management, ...

Since the applications of logistics are generally positive for the efficiency of transport systems, it has been suggested that logistics are environmentally friendly, thus emerged the concept of “green logistics”. Greening supply chains aim to balance marketing requirements with environmental issues. To meet challenges, such as energy conservation and pollution abatement, enterprises have tried...
