Why not sort big plastics before shredding it? According to Finnish firm ZenRobotics, with Heavy Picker it's possible to sort large and heavy plastics fractions with high purity before it is shredded.
The company claimed that its Heavy Picker unit is the strongest waste sorting robot on the market and suited to heavy and bulky materials with an ability to separate objects weighing up to 30kg.
The robot’s gripper opens from 50 to 500mm, allowing objects of various shapes and sizes to be sorted. ZenRobotics said that the Heavy Picker sorts numerous waste material types and various objects simultaneously in one spot, reducing the need for complex pre-processing of waste.
A single robot arm is said to be able to pick up to 4 different fractions with very high precision, reaching up to 98% purity.
The system can also be taught to identify and sort specific objects, such as garden furniture, pipes, crates etc. Furthermore, the robots can sort plastics by polymer or colour.

Automation is not new in the recycling industry, but the artificial intelligence behind the latest sorting robots is getting smarter. ZenRobotics ZRR can be ‘taught’ what to pick in a weekend.
In Depth: Recycling Robots 2.0
Once suitable for only niche applications, robots are now being developed that can sort household recyclables and differentiate between construction wastes. What will this mean for the human workers? Does it mean the start of the robot revolution?
