Introduction to Robotic Automation
Rapid technological advancements influence all sectors, and automation is playing a significant role in many industries. The application of robotics automation is beneficial in streamlining manufacturing processes and increasing productivity.
Robotic systems are designed with advanced sensors that can identify, locate, and sort materials with precision, like humans. Further, they do not suffer from fatigue and have a low error rate, which increases efficiency and reduces wastage. Their use in recycling plants has not only improved the quality of output but also minimized operational interventions and made sorting more cost-effective.
In the following sections, we will explore the impact of robotic automation in recycling and sorting processes, discussing its mechanisms, and exploring ideas to boost production with this cutting-edge technology.
How it Works: Mechanisms of Robotics Automation in Recycling
The use of robotic systems in material sorting has become essential in managing diverse types of waste. Optical sorters use cameras and sensors to determine the different types of materials being sorted and can identify and separate plastics, paper, glass, and metals from other materials, for example, food waste.
When a bale of mixed waste arrives, the conveyor belt transports it to an optical sorter. The optical sorter captures an image of the material stream as it rushes by and rapidly identifies materials based on their color, shape, size, and texture. Once the materials are detected, the robot arm is positioned to direct them to the correct area for further processing.
Robotic systems can further improve the process’s efficiency by using a combination of sensors, conveyors, and actuators to sort material in motion continuously. Some machines can move and sort up to 60 items per second and have the ability to identify materials that are shattered, flattened, or mixed with other types of materials. Therefore, the accuracy rate is higher than the manual sorting process, which is essential for proper recycling.
Real-life Examples: Application of Robotics Automation in Material Sorting
Robotic automation is already making a difference in industries worldwide and has become increasingly relevant in the recycling industry. A few notable examples are explained below, showing the versatility and impact these technologies are making.

Colorado-based AMP robotics has installed robotic sorting systems in recycling plants in North America and the UK. Their state-of-the-art system consists of custom hardware and software designed to identify and sort recyclable materials from mixed waste streams quickly. Amp Robotics’ AI identifies items quickly and accurately, with a pick rate of up to 80 items per minute. The robotic arm can spin and place the material in the correct location for further retrieval, and three sensors check for quality and contaminants while the machine refines its data each time. The system has been shown to identify multiple materials, including paper, cardboard, plastics, and metals.
Waste Warwickshire in England
Waste Warwickshire uses robots to augment their existing technology to accomplish their goals toward sustainability. They have developed a high-quality recycling system with the use of robotic automation that can handle mixed waste streams, single stream and can also sort free-flowing materials such as loose plastic bags, wire, and aluminum foil. The system processes up to 4.5 tons of material an hour and has robots with artificial intelligence, enabling them to identify different types of material, colours, sizes, and shapes, with a high level of accuracy
TOMRA in Norway
The Norwegian company, TOMRA, has installed over 6000 of their custom-built robotic recycling systems in plants all over the world. The system is powered by artificial intelligence and dual-cameras that detect and differentiate between materials such as glass, metals, and plastics. The automation system can decrease labour costs of 70% in some scenarios, significantly reduce errors, and decrease impact on the environment from truck emissions.
The Impact of Robotics Automation on Recycling
Robotics automation in recycling is transforming the materials sorting process. Recycling centres and municipalities are now able to achieve their sustainability goals efficiently and at a lower cost than the traditional separation method that requires manual sorting. Below, we’ll explore the advantages of robotics automation in recycling further.
Improves Sorting Quality
The most significant benefit of robotics automation in recycling is an improvement in sorting accuracy, with an increased ability to detect, classify, and remove contaminants that affect quality and purity of recycled materials. The accuracy and speed of robotic automation help to minimize human error through constant monitoring and analysis. The system reviews the input regularly, records mistakes, and improves operations to avoid repeating them. This results in a cleaner stream for reprocessing and a reduced environmental impact.
Reduces Manual Sorting
Automated robots reduce the need for labour-intensive, repetitive manual sorting, which requires significant time investment and incurs high costs. The conveyor belts and robotic arms, in comparison, can sort much more rubbish at an incredibly faster rate, with robots completing tasks 24/7 that would take humans numerous shifts to accomplish. The reduction of manual labour also helps reduce the chances of workplace injuries, and with more of the tasks removed from the hands of overseers, employee roles can be reshuffled to support higher-level jobs that require more sophisticated, nuanced thinking.
Increases Sustainability and Profitability
Recycling is profitable for businesses who profit from selling the recycled materials. A robotic system helps in maintaining a quality product by avoiding mixing materials and contamination, reducing scrap and rework and increasing the bale weight. Loading and unloading materials is faster, reducing truck idle time when waiting for manual labour assistance, resulting in a lower carbon footprint and emissions. Furthermore, it is environmentally sustainable to minimize waste when reducing the need for virgin materials extraction.
Current Use of Robotics Automation in Material Sorting
Many recycling centres worldwide have already incorporated robotics automation systems in their processes to optimize material sorting. Nevertheless, it is brand new tech, and not all facilities are using it yet. Below is a list of industries and companies that have already adopted these robotics automation systems.
