A relatively simple model, the associate species model, is being applied to nuclear waste glass compositions in order to accurately predict behavior and thermodynamic activities in the material. In the model, the glass is treated as a supercooled liquid, with the liquid species allowed to exist below their melting point. The approach requires an initial assembly of binary and ternary oxide liqu...

For several decades, Liquid Crystal Displays (LCDs) have been widely used in televisions, laptops, mobile phones, and other devices. Nowadays, liquid crystals (LCs) represent an important economic value of the recycling system LCDs. The reuse these organic molecules could become a profitable basis since it permits to preserve materials. In this context, general objective work focuses on recover...

One of focuses interest in engineering is that professionals remain active and update their different knowledge: knowing, doing being, this sense it essential young people training acquire skills, abilities competencies allow them autonomy the constant search for tailor-made solutions, considering forces environment, such as climate change citizens. The inclusion communities relevant when solvi...

Solid waste is generated at a rate of more than 4 lb per person per day. A significant portion of the non-recyclable waste is food waste, with high water content and low energy density. While most thermochemical conversion processes require a relatively dry feedstock, hydrothermal liquefaction uses subcritical water as the reaction medium and is therefore compatible with high-moisture feedstock...

Municipal sewage sludge is a solid, semisolid, or liquid muddy looking residue that results after plain old sewage (human and other waste from households and industries) is treated at a waste water treatment plant. Recent restrictions on the use of sewage sludge, however, have resulted in increased disposal problems. Sludge contains a variety of organic and inorganic compounds in the waste wate...

Need for an online hazardous waste tracking system Suneel Pandey Hazardous waste management is one of the most challenging aspects of any environmental management system for any industry. There are more than 50 000 chemical substances, with one million combinations, used in industrial activities. Hazardous wastes – in the form of solids, liquids gases or sludge – are generated by a wide range o...

Organic fertilizer regimens consisting of combinations of composts (yard waste, swine manure, or spent mushroom substrate) and liquid fertilizers (fishor plant-based) were evaluated against conventional hydroponic fertilizers in two experiments with greenhouse tomatoes grown in peat-based substrate. Crop yield and fruit quality were evaluated and several assays of substrate microbial activity a...
