Innovative Bottle-To-Bottle recycling
Total Solution from bottle flakes to clean chips -- USEON always eyes on energy saving during production
How to make the clean flakes back into the virgin chips that could be used for injection of preforms and how to save the energy during the whole process are what USEON is trying. Actually, through our systemization of whole process, we have approached great improvement on the process technolgy and energy saving.
Firstly, with our efficient quick-drying process, clean flakes could be predried up to 2000ppm. Here no any strict predrying units or crystallization units are required. Then, our best TDY counter-rotating twin screw extruders could finish the plastication, with nearly zero IV drop. This point has great importance to save energy, meaning less SSP residue time for higher IV. Fine filtration could be done with our continous screen changers. Our underwater cutting units are specially designed for this BTB systems to control the residue temperature inside the granules. What's most important for the system is that USEON's inline crystallization and SSP process will increase the IV to the data as virgin chips for bottle preforms. This latest technolgy could save the total energy up to more than 40%.
