Transforming plastic waste back into valuable raw materials requires robust and precise solutions that can reliably dose and process a wide range of feedstocks. This is especially important when dealing with heterogeneous recyclates. Chemical recycling offers significant potential to bring even hard-to-recycle plastics back into the loop.

Many systems reach their limits when it comes to recycling. Inconsistent materials with very low bulk densities and poor flow properties frequently lead to blockages, bridging, or uneven material flow. According to data published by the OECD, globally, less than 10% of plastic waste is recycled. The vast majority is either incinerated, landfilled or ends up polluting the environment. This is not only a burden on the environment and resources, but also highlights the urgent need for more efficient recycling technologies and infrastructures.

“When recycling works reliably, the plastics industry achieves both sustainability and profitability. Qlar’s advanced technologies, built on decades of expertise, are key to this transformation, enabling precise material dosing, efficient processes, and a truly circular economy.”

How Qlar Turns the Tide in Plastic Recycling

Qlar addresses these challenges with advanced feeding solutions tailored to recycled materials. The SIMPLEX Flat Bottom Feeder, for example, is designed for handling shredded plastic film, fibers, and preconditioned post-consumer plastic waste, ensuring efficient material feeding and uninterrupted processing. With a sophisticated agitator, the SIMPLEX FB is ideal for hard-to-feed materials such as shredded plastic film when feeding into an extrusion process.

Reliable dosing is key to transforming recyclates into valuable plastic products – which is exactly what Qlar’s MultiFlex NG/NG+ feeder is designed to deliver. This gravimetric weighfeeder is designed for stable material flow in demanding recycling environments. It features a hopper for short-term material storage and buffering fluctuations in the conveying line, supported by three independent weighing circuits with high-precision load cells. In the NG+ version, enhanced weighing mechanics make the system suitable for highly accurate feedstock metering. The twin-screw trough controls the feed rate via a variable frequency drive, providing a broad feedrate-range. 

Qlar’s hardware is complemented by intelligent digital solutions. The CONiQ Cloud is a cloud-based platform that captures, analyses, and visualises sensor and process data in real time. It enables continuous monitoring of key parameters such as mass throughput, dosing accuracy, and material flow. Predictive maintenance helps prevent unplanned downtime and extends equipment life. The platform also allows for responsive, data-driven control of complex recycling processes which is essential when dealing with fluctuating material qualities. As a core tool for Industry 4.0 strategies in plastics recycling, the CONiQ Cloud significantly boosts overall system efficiency.

Building a Circular Future

Whether in mechanical or chemical recycling: Qlar solutions accompany the entire lifecycle of plastics. Drawing on decades of process know-how, Qlar develops solutions that are precisely tailored to the demands of recycling applications. With unique feedstock dosing systems and intelligent digital integration, Qlar optimizes the recycling process itself, ensuring precise material dosing and improved process efficiency. The result is a plastics industry that is both high-performing and sustainable.

When recycling works reliably, the plastics industry can combine ecological responsibility with economic success. Qlar plays a decisive role in this transformation with technologies that conserve resources, stabilise processes and close the loop.
