Abstract
The recyclability of polystyrene, acrylonitrile butadiene styrene and polyvinylchloride waste and their use as a source for 3D printing were studied. Filaments of about 3 mm in diameter were extruded successfully with a small-size extruder. The processed filaments were tested on a broad range of parameters-melt flow index, glass transition temperature, tensile properties and a pyrolysis scenario were obtained. The measured parameters were compared with parameters of virgin counterparts presented in the literature. In order to estimate the composition of the recycled material, Fourier Transform Infrared and elemental analysis of the samples was done.
Highlights
Plastic, being a highly versatile and resource-efficient material, has become irreplaceable material in many economic sectors, such as packaging, building and construction, transportation, and renewable energy, among others [1]
The main aim of this study was to estimate the recyclability of ABS, polystyrene (PS) and polyvinylchloride (PVC) plastic waste, i.e., to measure the mechanical and physical properties of filaments manufactured from these plastics and to compare them with virgin grades
Filament samples of about 3 mm in diameter were extruded with a small-scale extruder from recycled polystyrene (PS), acrylonitrile butadiene styrene (ABS) and polyvinylchloride (PVC) materials
Summary
Plastic, being a highly versatile and resource-efficient material, has become irreplaceable material in many economic sectors, such as packaging, building and construction, transportation, and renewable energy, among others [1]. Statistics show that of the 27.1 million tons of post-consumer plastic collected in 2016, 31.1% was recycled, 41.6% incinerated and 27.3% landfilled. A large portion of plastic is still landfilled; this was the first time in Europe when recycling overcame landfill [1]. In the European Commission Action Plan for a circular economy from 2015, plastic production is identified as a key priority [2]. The circular plastic economy vision is based on the need for innovative solutions for developing new sustainable products, durable with a long lifespan, and for high-quality recyclable products after use. Among other waste management options, mechanical recycling of plastics is the most resource-effective, providing more jobs than landfilling or incineration [3]
