the growing scarcity of fresh water is driving the implementation of wastewater treatment and water reuse on an increasingly large scale. various methods have been developed and used for water reuse from wastewater; however, the membrane distillation (md) process, as a promising separation technology, has recently gained more attention. the md process is a non-isothermal membrane-based separati...

The Cover Feature shows the desirable life-cycle for polyolefins, leading from small building olefinic blocks to polymeric materials present everywhere in our daily life and use of transition metal catalysis cut recycle polymers back smaller molecules or new blocks. In their Review, M. Hapke co-workers compiled state-of-the-art chemical recycling polyethylenes polypropylenes at rather low react...

inventory management in production-remanufacturing system has been receiving a great deal of attention in recent years. in literature review, production environment is composed of two sections. the first section is included: production process, remanufacturing process and other options considered in reverse logistics. the second section is included: collection and sorting processes. determinati...
