The plastic waste material is first shredded to a particular size using a shredding machine. The aggregate mix is heated at 165°c and transferred to the mixing chamber, and the bitumen is heated to 160°c to result in good binding. It is important to monitor the temperature during heating. The shredded plastic waste is then added to the aggregate. Fuel from Plastic Waste - Research Trend waste plastics can be minimized. Plastic in the first place is manufactured from natural gas specifically from ethane which is a constituent of natural gas. Therefore the waste plastic can be converted back into it. For the process of conversion a machine can be used which will heat the plastic to a temperature so that it melts and does not burns. Biodegradable Plastic: Facts, How It Works, and Research Important Facts to Know. 1. Biodegradable doesn’t equal compostable. Conventional petroleum-based plastic items never decompose in a landfill.
