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...

Due to recycling of metals, most foundries have considered themselves as a part of the green technology before the term “green’’ was even coined. But, actually, the foundry industry handles large quantities of processed waste materials and has the potential to emit a large quantity of carbon dioxide and other pollution in atmosphere. This immense pressure not only forcing foundry industries to ...

This paper aimed to compare household waste, separated pig solids, food waste, pig slaughterhouse sludge and green algae regarding processes ruling nitrogen dynamic during composting. For each waste, three composting simulations were performed in parallel in three similar reactors (300 L), each one under a constant aeration rate. The aeration flows applied were comprised between 100 and 1100 L/...

1 This paper aimed to compare household waste, separated pig solids, food waste, pig slaughterhouse sludge 2 and green algae regarding processes ruling nitrogen dynamic during composting. For each waste, three 3 composting simulations were performed in parallel in three similar reactors (300L), each one under a constant 4 aeration rate. The aeration flows applied were comprised between 100 and ...

The three processes of urbanization, industrialization and globalization are positively correlated with municipal solid waste generation and energy consumption in global urban centers. Heavy reliance on fossil fuels in most world cities has contributed not only to global warming and climate change, but also to astronomical increases and volatility in the prices of energy sources. Africa has suf...

The information technology is powered by electricity. Although its impact on Green House Gasses (GHG) is still rather limited, the next decade will show an explosion of its impact because technological innovations in data communication, information retrieval and datacenter operation will not compensate the increased need for energy of information technology. This paper approaches the problem no...

Recently, with the environmental crisis, Green supply chain management (or GSCM), and in particular closed loop supply chain model, has received considerable attention by researchers. Closed loop supply chain model aims at reduction of waste and generating profit for enterprises through integrating forward and reverse logistics. Unfortunately, there is limited research on general models for clo...
