Hyderabad: A research team from the University of Hyderabad has developed a simple and low-cost plastic waste recycling system in a bid to save the environment from hazardous emissions caused by random incineration.

Rajendhar Junjuri, research scholar, ACRHEM, and Dr G. Manoj Kumar, Assistant Professor, ACRHEM from the University of Hyderabad demonstrated a simple and low-cost method of sorting the plastic.

The generated data were combined with machine learning to identify the type of the unknown plastic. This system demonstrated successful identification of samples from plastic waste with an average accuracy of around 97%. Their approach has great potential in realizing a low-cost sorting system for plastic waste recycling.

"Low-Cost Sorting of Plastic Waste" authored by Mr. Rajendhar Junjuri and Dr. G. Manoj Kumar has been published in Optics & Photonics News (OPN) year review 2020. OPN is the Optical Society of America (OSA) publication.

Each year, OPN highlights the most exciting optics research to emerge in the preceding 12 months. This year 30 intriguing works were selected out of 115 summaries submitted by various research teams across the globe.


It is to be noted that every year, several million tons of plastic waste is leading to a landfill problem and their incineration is polluting the environment.

The ever-increasing domestic and industrial plastic waste raises more concerns over their recycling which offers an efficient solution to minimize waste output and reduces the usage of natural resources. However, sorting is a crucial step in the recycling process as it affects the quality and cost of the final products.
