Potentiometric sensing and electrochemical recycling of cadmium ion have been demonstrated over chemical interactive electrically conducting bio nanocomposite film comprised zinc oxide, sodium alginate, polypyrrole (ZnO/SA-g-PPy) using...

Considering environmental impacts in the design phase of chemical processes is one of the greatest challenges for the chemical industry. In this work, we propose a systematic process design procedure that incorporates Life Cycle Assessment (LCA) as an environmental metric in addition to the conventional economic optimization. Integration Definition Function Modeling (IDEF0) is used to represent...

BACKGROUND AND OBJECTIVES: The sheer volume of electrical and electronic waste (e-waste) has presently been generated in Vietnam, posing a growing concern regarding its impact can have on the environment and human health. Therefore, the need for developing policies and regulations towards the environmentally sound management of e-waste is becoming crucial. Although the municipa...

The importance of recycling and utilization of recycled fiber has recently been recognized because of concerns about environmental issues and economic aspects. In spite of several advantages offered by paper recycling such as wood savings through substitution of virgin pulp and reduction in chemical usage, recycled pulp also contains plenty of fines having high relative surface area and hig...

introduction a large number of orthodontists prefer to rebond the failed bonded brackets or use recycled brackets in some instances. the aim of this study was to compare the shear bond strength of rebonding with using recycled brackets on enamel surface. methods bonding of brackets on the surface of extracted first bicuspids was tested in five different groups to compare their shear bond streng...

high levels of weee and limited capacities for disposal and recycling, together with thenecessity to transpose the european legislation into national law have shaped the profile of weee system inromania. in order to improve the functionality of this system it is important to understand the citizens’behaviour towards weee recycling. recent research conducted in different countries suggest that v...
