this study aims at investigating social and cultural barriers to the use of recycled water for the first time in iran from the sociological perspective. applying qualitative methods, the understanding of women from water recycling and causes and conditions for the use of recycled water was studied. the required data was collected by using semi-structured interviews with a number of women. the i...

We are in a global plastic waste crisis. Plastic production has steadily increased over the last half century, while recycling rates remain as low 9% some nations, including Australia. Most ends up landfill or environment lost resource, triggering of more virgin to satisfy demands. Shifting away from this wasteful, linear economy towards circular economy, where products treated valuable resourc...

Although there is no doubt that composite materials are the future of lightweight structures and components, most composites currently produced made from thermoset polymers, which not able to be recycled or reprocessed. In contrast, thermoplastic polymers offer possibility recycle reprocess when combined with a fibrous reinforcement, provide interesting mechanical properties. This work reviews ...

Currently, only 1% of waste textiles, mainly whites, are recycled because dyes on fibers caused various problems. Unseparated colors might sublime during the fiber regeneration process and pollute working environment. More seriously, final color quality regenerated is uncontrollable. Technologies for complete removal from textiles either by dye-destruction or extraction have major challenges im...

In this study we explore the implications of using recycled versus virgin materials for the supply chain structure and supplier relationships as well as the broader effects on operations strategy. We focus our study on the corrugated cardboard industry, where vertical integration is common, and non-integrated firms are both customers and competitors of integrated firms. These multiple supplier/...

Reducing waste material plays an essential role for engineers in the current world. Nowadays, recycled materials are going to be used in order to manufacture concrete beams. Previous studies concluded that the currently proposed formulas to predict the flexural and shear behavior of the reinforced concrete beams were not appropriate for those manufactured by recycled materials. This study aims ...
