The proper design of a product life cycle may contribute both to the optimization of primary raw material usage and to the reduction of waste environmental impacts. Recycling may enter the life cycle of products in the contexts of production of secondary raw materials and reduction of waste extensive disposal in landfills. Tradition plants for plastic separation in homogeneous products employ m...

The final features of natural fiber composites (NFCs) depend on the integrated characteristics of their constituents. In the industry today, natural agro waste fibers are evaluated using a limited number of criteria. In this work, a combined multi-criteria evaluation stage technique (CMCEST) is introduced as a simple efficient systematic indicator to enhance evaluation of the available natural ...

Received: June 06, 2017 Revised: July 05, 2017 Accepted: July 19, 2017 Abstract: Introduction: The use of polymer wastes in pavement as road is an increasing trend in the road construction sector. Those new pavements reduce the amount of solid waste disposed into landfills and provide more sustainable construction due to the use of in-situ materials. Polyurethane foam waste is a thermostable po...

The Basel Plastic Waste Amendments reflect growing global concern about the illegal plastic waste trade as colonialism. Comprehensive analyses of material sources, pathways, and fates are needed for effective policy. Plastics flows from Palmerston North, New Zealand to Malaysia highlight potential gaps in policies. authors recommend strengthening Zealand's national policy framework Convention's...

The Plastic Waste phenomenon, which is the result of increasing poly (ethylene terephthalate) production and the wide range PET consumption in different industries, caused one of the major environmental concerns. Therefore,many different ways have been studied and applied for chemical recycling of PET. One of the most important ways to depolymerize poly (ethylene terephthalate) is the aminolysi...
