Recycling HDPE (High-Density Polyethylene) has become a more efficient process nowadays due to the recent developments in recycling technologies. The use of HDPE in common products like milk jugs, detergent bottles, and pipes means that the improvement of recycling is the major way for the reduction of plastic waste and the conservation of resources.
The main improvement is related to the introduction of more sophisticated sorting technologies. The traditional recycling systems used to have problems in the recognition of different kinds of our plastic. The new systems are now using optical sorting as they can get reliable results by being able to detect and separate HDPE from the other materials. This decreases the extent of contamination and then the general quality of the recycled plastic is increased.
The new concept that has been introduced is the utilization of chemical recycling. The traditional mechanical recycling is the procedure of auto-feeding the plastic until it melts which is done by shredding and hence it is the opposite of chemical recycling which decomposes HDPE in its components. The manufacturing of plastic in this way is cost effective and functional and the plastic units end up being just as good as before. Chemical recycling is usually thought to be the best thing for plastics that have been previously used many times and hence they have become harder to be processed through mechanical means.
