Scrap Metal Recycling: Substantial Development in Sorting and Processing Material

By preserving more recyclable material in a shorter time, laser technology for scrap metal processing can result in significant savings.

FREMONT, CA: It took time in the scrap metal recycling industry to sort the incoming material by hand, write tickets by hand, and carry out the bookkeeping by hand (with perhaps the help of a calculator.) The scrap metal recycling industry is currently at the forefront of technological innovation, using new technologies to make more efficient, precise, and faster process materials. Technology implementation in the recycling industry has been used to increase recycling rates and keep up with changing materials and products joining the waste stream.

Sorting and Processing Material

In recent times, many technical advancements have been implemented in scrap metal recycling yards to aid in the sorting and processing of waste. This technology was deployed to help speed up the process of manually sorting things and handle the changing nature of the intricacy of materials in the waste stream and the complexity of items like electronics. The goal has been to enhance the amount of recycled material while also speeding up the processing. Consequently, improved scrap sorting can help businesses generate 'cleaner' batches of material for further processing.Metal Recycling Companies

Sensors and sorting machines now do a lot of the labor that used to be done by hand. To sort non-magnetic metals, companies are working on x-ray technologies and infrared scanning. Non-metals are identified using Laser Object Detection (LOD), which eliminates them before processing. By preserving more recyclable material in a shorter time, laser technology for scrap metal processing can result in significant savings.

Scrap metal recyclers benefit significantly from the use of XRF or x-ray fluorescence. This technique can positively explore a range of alloy grades and test their chemical composition quickly at material transfer points, assisting in product quality assurance. Material identification is efficient and dependable with handheld XRF analyzers. Metals, alloys, and pollutants are detected by these and other handheld equipment that uses x-rays and lasers. They can also be outfitted with technology that enhances sorting by quickly determining the chemical composition of most scrap material.

This is a substantial development in technology as today there are many different kinds and grades of metals. After that, the material needs to be identified through sophisticated procedures.

An additional challenge mandating new technology is the volume of electronic devices that enter the waste stream. Although they are made from precious metals, they are so small that recovery without new technologies is not cost-effective. E-waste separation calls for more advanced, innovative technological equipment. Certain large recyclers are now using infrared and x-ray technology to select valuable metals from e-waste streams.
