Optical laser applications have been incorporated into many technologies and industries over the past 60 years. This emphasis on leveraging the latest technology has allowed them to reduce costs and increase material capacity in significant ways. As more and more people become aware of the need for recycling at all levels, the industry must evolve to accommodate the increased inflow of materials. The new efficiencies the industry is starting to cultivate take many forms of technology. Balers, conveyor technology and laser sorters are key components in machinery that is rapidly gaining popularity.

There are hundreds of balers and various types of processing equipment on the open market in recycling centers. However, these machines can only be used at optimal levels if the material has been sorted in advance. To meet this demand, sorter technology has become the new frontier of innovation. There are currently two main types of sorters leading the market: laser sorters and digital optical sorters. Each of these technologies has its own advantages when it comes to recycling.

Optical sorters allow automatic sorting of a wide range of materials, including glass, paper, e-waste, plastics and metals. The application of this sorting technology involves many areas of the recycling process. They can be installed with single-stream recovery and dual-line. They can also be used for single-stream recycling with municipal solid waste treatment and construction or demolition waste. In addition to single item sorting lines, the level of efficiency of laser sorting machine can benefit complex processes.

The laser sorting process offers some more advanced benefits. These sorting units can be modified to handle a variety of different materials on the same line. This capability eliminates the need for recycling centers to install multiple platforms for different materials. In most cases, existing hardware can be converted. There is also no limit to the materials that can be sorted. Everything from paper to iron ore can be separated by a laser process. The flexibility of such a system depends on how the classification is done. The technique judges each item based on its color, structure and shape. Manipulating these variables allows the system to distinguish almost any known material. The evaluated products are then divided into acceptance and rejection flows.
New laser sorting solutions from Hefei Growking Optoelectronic are unlocking untapped opportunities in the market and providing our customers with innovative and cost-effective solutions to extend the life of their deposits. Analyzing test and real-world trial results from multiple installations, we demonstrate that higher recoveries, better quality, and more consistent material sorting can be achieved using laser sorting compared to other sensor technologies.
