Plastic intelligent sorting technology breakthrough!

Although we have made some improvements in plastic recycling in recent years, plastic landfill is an increasingly serious problem. Soft plastics such as plastic wrap and plastic bags are the main cause of this problem, with 94% of the plastic being landfilled in 2016-17. Soft plastics lack adequate recycling methods because they are easily entangled in waste sorting machines, causing mechanical failure and polluting other recyclable materials such as paper. Due to this problem, the current recycling method relies on manual sorting of soft plastics, which is often repetitive and unsafe.

Soft plastics, a major contributor to landfills, have long been a challenge for the recycling economy and waste management sector, because they have been lacking adequate safety classification methods, the researchers said. With the latest Internet of things technology, they created a custom robot to solve this problem, and most of the soft plastic waste was recycled. Robots will identify home use soft plastic bags and distinguish the source of plastic, separating soft plastic from fully mixed recyclable materials.

After being separated from other wastes, soft plastics will be used for various purposes, including the use of catalytic hydrothermal reactor technology (cat HTR), which can recycle soft plastics into oil and other valuable chemicals. This highly innovative material handling process can help expand the available range of cat HTR conversion technology.

 

Separation technology is an important part to improve the purity and utilization value of waste plastics

Waste plastics, a resource with high economic value and recycling value, plays an important role in the field of recycling. What is more troublesome is that most of the common plastic waste in life is mixed. Therefore, for recycling practitioners, how to better purify the plastic is very worthy of attention. At a small scale, this determines whether we can get a good price for plastic recycling. At large, it determines the quality of plastic recycling and how much resources we can save.

The price of waste plastics is generally determined by the quality and complexity of waste plastics. The cleaner the plastics, the more valuable they are.

Obviously, we can’t intervene to improve the quality of plastics. What we can do now is to reduce the impurities in plastics and enhance its value by improving the purity of waste plastics. Of course, we can improve the quality of recycled plastics in the separation process.

Intelligence and automation will be the development trend of resource recovery and sorting

In recent years, with the development of science, artificial intelligence technology is gradually mature and involved in the field of renewable resources recycling. NRT and machine recently released their new sorting robots Max aitm and samuraitm, which have been installed and used in relevant resource recycling enterprises, and achieved good results.

In addition, the AI sorting robot can continuously improve through learning, so as to improve the overall system performance, ensure the most accurate identification, and achieve the highest recovery rate and purity level. Sensor technology, communication technology and computer technology constitute the three pillars of modern information technology, which play the role of “sense”, “nerve” and “brain” respectively in the information system.

Through the excellent sensor technology, the artificial intelligence sorting robot can analyze the composition of the target materials, achieve the effect of identifying the types of waste plastics, and use the mechanical arm for high-speed sorting. It is believed that with the development and popularization of artificial intelligence and sensor technology, intelligence and automation will be the trend of resource recovery industry in the information age.
