Supporters of single-use plastic bag bans implemented or being discussed across South Carolina believe limiting plastics would decrease litter and waste.

A machine learning (ML) program was then trained on this data, and subsequently employed to look at and sort individual pieces of plastic waste.

Canon attributes the machine's high-precision, high-speed sorting of plastic (including black pieces) to its combination of Raman spectroscopy with a tracking mechanism.

Can This Machine Automatically Sort Balls by Color? A video purportedly showing a "Galton board" apparently sorting balls by color perplexed many viewers.

Or maybe you get a certain satisfaction out of sorting your candies by color before eating them? One 19-year-old student found a solution: a candy color-sorting machine.

The machine is 250 mm in diameter and approximately 300 mm in height,” writes Pennings. The system uses an RGB sensor to assess the color of the candy and place it into the proper dish.

After seeing a color-sorting machine years back, Pennings decided to create his own and use it for the ultimate good: to sort shitty Skittles flavors so we don’t have to eat them.
