Plastics Recycling using Archimedes Screw in Birmingham Plastics Recycling Start Up Invests in Birmingham     Recycled Prolymers’ new TR-150V die face cutting pelletizing machine 10 October 2011A newly formed company, Recycled Polymers Limited, based in Birmingham, UK is to recycle industrial waste plasticsusing specialist machinery.According to the company, following a granulation process, it will produce a clean, pelletized product ready for use in plastics moulding and extrusion processes.   Recycled Polymers says that it has invested £750,000 in the venture, which includes a new purpose built machine designed in the UK and built in Taiwan, and a new 1000 square metre facility. Financial backing has come in the shape of equity investment managing director, Grant Gerry and the other directors, as well as asset finance from HSBC Commercial Finance and Close Brothers. The company will recycle a wide range of materials, including Polypropylene, polystyrene, HDPE (High Density Polyethylene) and ABS (Acrylonitrile Butadiene Styrene). According to the company, the new machinery will allow the plant to consume 60% less electricity than older equipment and is also faster and cleaner in operation. Gerry claims that the savings made inenergy costs will be reflected in the price of the output material. The company says that it has already won contracts to recycle the waste from specific industry users back into their own manufacturing environment, classed as service work. The newly formed business is being mentored and chaired by entrepreneur Andrew Selby, who has built up and sold a number of businesses over the last four decades. “We plan to grow this business rapidly because we are convinced of the urgent and increasing environmental demand for efficient quality recycling and the market opportunities for recycled materials,” comments Selby. Machinery Designed in the UK, the TR-150V die face cutting pelletizing machine is made by Taiwanese company, Kween B. It features a 150 mm diameter barrel and according to the company, is in essence an extruder used for reprocessing granulated waste plastic back into granules for reuse in injection moulding and extrusion   The machine processes a number of waste plastic materials into pellets. Recycled Polymers says that it will be concentrating on PP (polypropylene) PS (polystyrene) HDPE (high density polyethylene) and ABS. The compounding process is very similar to injection moulding. Plastics and additives are metered into a hopper at one end of a barrel. The material is transported along the length of the barrel via an Archimedes screw and is melted by applying heat via external heater bands as well as the friction (shear heat) generated by the action of the screw(s) within the barrel of the compounding extruder. As the material travels along the barrel, specially designed sections of the screw knead, mix and compound the plastic. Additives and fillers are added via side-feeders. At the end of the barrel, the melted plastic flows through a wire screen that filters out any residual dirt, grit or other contaminants, and is then forced through a die plate.  Special openings (vents) allow any volatiles to be removed. As the material comes through the die plate, it is cut into pellets and then cooled in water or by air and subsequently dried during transfer to a packaging station at the end of the line. Recycled Polymers´ says that its feedstock comes from scrap/waste arising from plastic injection moulding and/or extrusion factories which produce scrap/reject moulded products during their process. The finished product (Black pellets) is sold back into the above industries to manufacture various products such as coat hangers, buckets, water butts, plant pots, DVD cases, storage boxes, drain covers, water pipes to name a few. According to the company these products can be made 100% from our recycled material.   Plastics Recycling using Archimedes Screw in Birmingham http://www.archimedeshydroscrew.com/plastics-recycling-using-archimedes-screw-in-birmingham/ http://www.archimedeshydroscrew.com/plastics-recycling-using-archimedes-screw-in-birmingham/ http://www.archimedeshydroscrew.com Read more at dabasiah.posterous.com
