Currently, pollution due to textile materials is a crisis that threatens the whole world. Due concern for environment, our society has faced challenges when it comes finding eco-friendly substitutes fibers and leather materials. This can be achieved using renewable or recycled polymers are either readily biodegradable easily at end of product's life. Thus, material made from natural resources, ...

This paper investigated the moisture and strength properties of wood-polymer composites (WPC), which were made using three different recycled polymers wood flour as filler. The acrylonitrile butadiene styrene (ABS), polypropylene (PP), polyethylene (PE), collected from among construction demolition waste (CDW) at a local management center. commercial additives, such coupling agent lubricant, al...

Full scale tests with crushed concrete used in sub-bases in roads show that the material has capacity to reharden, very slowly but also after prolonged periods of time. The rehardening process in crushed concrete aggregate has been analysed with a thermogravimetric method, comparing the change in chemical composition in the aggregate when set with water, compacted and hardened. It has been show...

This paper describes a study for waste of electrical and electronic equipment (WEEE) to characterise the plastic composition different mixed fractions. Most samples studied are currently excluded from material recycling arise as side streams in state-of-the-art plastics plants. These contain brominated flame retardants (BFR) or other substances concern listed persistent organic pollutants RoHS ...

A significant portion of the global plastics market encompasses production polyolefin materials and especially polypropylene (PP) polyethylene (PE), as commodity polymers with a wide range applications. However, increase in generation unsustainable plastic waste requires close technological look-up to address this challenge adequately. In context, mechanical recycling is part strategies expecte...

Plastic Bonded Explosives with inert binder despite having good mechanical properties and low sensitivity, because of containing inert materials, have low energy level. So investigations for replacing inert binder system with energetic binder system and high exploding components in the making of these materials are performing. It seems using energetic polymers and materials like Cyclotetramethy...
