In this work, the influence of three types of styrene maleic anhydride (SMA) oligomers on the adhesion of polystyrene wood plastic composites (WPC) was investigated. The composites were processed on a twin-screw co-rotating extruder below 200°C using 20 wt% of wood flour. The styrene maleic anhydride with different content of maleic anhydride groups, 30%, 25% and 20% (w/w) and levels of 1, 2 an...

The seismic performance of recycled aggregate concrete (RAC) composite shear walls with different expandable polystyrene (EPS) configurations was investigated. Six concrete shear walls were designed and tested under cyclic loading to evaluate the effect of fine RAC in designing earthquake-resistant structures. Three of the six specimens were used to construct mid-rise walls with a shear-span ra...

ABSrRAcr: Material properties of composites prOOuced from ruycled plastics and ruycled ~ fiber were compared. A blend of high -density polyethylene aIKi polystyrene was used as a simulated mixed plastic. Stift'ness was generally improved by the addition of fiber, as expected, but brittleness also increased. Pre-treatment of the ~ fiUer with phenol-fonna1~ resins did not significantly a~t materi...

Expanded polystyrene is widely produced and used due to its properties and, recently, ability present π–π interactions has been described. Therefore, this work proposed use recycled for solid phase extraction of 12 polycyclic aromatic hydrocarbons (PAHs) in aqueous samples. Recycled films were formed characterised by Fourier transform infrared spectroscopy, scanning electron microscopy affinity...

In this work, the presence of biodegradable polymers in recycled plastic materials was characterized using readily available techniques. Recycled polypropylene (PP), polystyrene (PS) and polyethylene terephthalate (PET) were studied. The contamination these plastics with polylactic acid (PLA), polyhydroxybutyrate (PHB) thermoplastic starch (TPS) simulated 10 wt.% contaminant. Fourier transform ...

Plastics have become indispensable in our daily lives, but plastic waste has proliferated landfills and oceans since most plastics are non-biodegradable cannot be mechanically recycled. Existing chemical recycling processes such as pyrolysis hydrogenolysis typically use high temperatures, generate unnecessary greenhouse gas emissions, often require expensive noble metals, show limited generalit...
