Simplex Feeder Empowers Plastic Waste Reduction
The plastics and performance materials industries are at the forefront of critical initiatives to increase recycling, reduce waste and to minimize human impact on the environment. The most successful plastic producers and processors are focused on consistently producing high-quality products while improving sustainability practices, demonstrating their commitment to the Circular Economy.
The European Commission’s ‘A European Strategy for Plastics in a Circular Economy’ aims for the recycling target to increase from 22.5% to 55% by 20251. To help negate their environmental impact, these manufacturers are investing in solutions and technologies that deliver on their goals towards more optimized and sustainable processes.
As a leading global provider, Schenck Process develops sustainable feeding solutions to support the Circular Economy, ensuring that products are handled and fed with precision, even when it comes to more challenging recycled materials with heterogenous characteristics such as particle size and form or bulk densities.
Recycled materials are often lightweight and fluffy, making them more difficult to handle and presenting challenges when feeding them to an extruder. Schenck Process designed its SIMPLEX Flat Bottom (FB) feeder specifically to handle recycled materials, such as shredded plastic film, fibers, or post-consumer waste. The SIMPLEX FB operates as a post-industrial feeder but can also manage post-consumer plastic material without pre-treatment with the added benefit of avoiding the more costly, risky, and less environmentally friendly step of melting and processing waste materials.
Need for the SIMPLEX FB Feeder
The SIMPLEX FB was initially designed as a solution to a customer's challenge involving feeding shredded film waste and reworking it into their extruder lines. In response to the customer's requirements, the team at Schenck Process developed and created a sustainable solution that did not require the material to be pre-shredded or processed. Integrating the film edge clippings back into the film production process allowed every scrap of plastic to be used without sacrificing product quality.
By recognizing that the plastic and performance material industries needed a cost-effective, sustainable solution that could increase recycling and reduce waste, Schenck Process was able to provide this customer with a highly accurate feeding solution for recycling their lightweight material.
The SIMPLEX FB has since been used successfully in many other recycling applications, including packaging manufacturers feeding sawdust and carpet producers reusing shredded carpet tiles that would have otherwise gone to waste.
Key Benefits of the SIMPLEX FB Feeder
The innovative SIMPLEX FB feeder family enables manufacturers in the plastics industry to handle a wide range of light, fluffy, organic, inorganic, or virgin recycled materials without contamination, such as chopped polypropylene or PET plastic film to an extruder. Other examples include:
- Other chemical materials with bulk densities of 0,01 - 0,5 kg/dm³
- Raw materials from organic cultivation
- Recycling materials (SRF)
- Plastic flakes
- Glass fibers
- Carbon fibers
The SIMPLEX FB is a modular loss-in-weight or volumetric feeder fitted with a bottom-driven vertical agitator and an auxiliary agitator for safe, accurate, and homogenous material dosing. Its stainless-steel cylindrical hopper can prevent bridging and when combined with internal agitation, it promotes mass flow while maintaining consistent feed rates up to 31 m³.
Flexible and Adaptable Solution for Tailored Customer Needs
Customers can operate the SIMPLEX FB in conjunction with several other feeders within their process. The packaged hopper refills the SIMPLEX FB quickly to maintain consistency and an optimal feed.
Alternatively, the volumetric version can be utilized as a refill system or surge bin for smaller loss-in-weight feeders. For added flexibility, the SIMPLEX FB is suitable for heavy-duty applications, and the discharge may be placed on the left or right side to ease integration into the process. Schenck Process also supplies the SIMPLEX FB Mini, which is ideal for achieving optimum results with lower throughputs.
Schenck Process has also installed the SIMPLEX FB at its Test & Innovation Center in Darmstadt, Germany. Here, customers can test their materials to appreciate how SIMPLEX FB could revolutionize their process and help them meet their sustainability goals. These tests can now be performed remotely to save CO2 and valuable processing time.

SPG with very limited business exposure to Russia, Ukraine and Belarus.
Given the tragic situation in the Ukraine we want to inform our investors about SPG’s business in the conflict region:
- SPG has legal entities in Russia (PRU) and Ukraine (PUA), currently employing 10 and 11 people accordingly. Focus of these entities is largely on customer service.
- 2021 sales in Russia and Ukraine contributed around 1% to the Group’s revenue
- SPG Management board has decided to currently not accept any new orders from Russia and Belarus and to pause the execution of our current order book of ~5m€ in that region.
- We remain in close contact with our Ukrainian colleagues and are working together to offer any support and to ensure the safety and well-being of them and their families. Currently, all our local employees are in places they consider more or less safe.
- We currently do not expect significant ripple effects of the ongoing conflict to our global business.
We are continuing to monitor the situation very closely. Any further adjustments or changes will be advised separately.
