At Greenbank Recycling Solutions, we’re committed to delivering industry-leading recycling systems while driving innovation in material processing technology, particularly in the handling of Expanded Polypropylene (EPP).
With over 30 years of experience aligning customer needs with the right machinery solutions and a team serving the UK market for over two decades, we continue to refine, test, and improve the way EPP and other foams are processed and recycled.
Our ongoing material trials give us unique insights into how different materials perform under real-world compaction conditions. This ensures our machines can handle diverse recycling streams with speed, reliability, and efficiency, helping businesses achieve their waste reduction and sustainability goals.
What Is EPP and Why Is It Important?
Expanded Polypropylene (EPP) is a tough, lightweight, and highly versatile foam widely used across industries such as automotive, packaging, construction, and consumer goods. Its durability and high thermal resistance make it ideal for reusable packaging and protective components.
However, these same properties make EPP harder to compact and recycle compared to traditional expanded polystyrene (EPS). That’s why Greenbank Recycling Solutions is committed to testing and optimising our machines for EPP processing.
By doing so, we help businesses transform EPP into valuable resources instead of costly landfill.
Greenbank’s Approach to EPP Material Trials
To guarantee that our compactors meet the highest performance standards, we conduct in-house EPP material trials using our latest models. One recent trial focused on material generated from the automotive sector, a common source of EPP.
During these tests, our engineering team worked to measure compaction ratios and determine optimal processing speeds, assess how different grades of EPP behave under pressure, test thermal consistency and evaluate machine output quality and ensure long-term reliability of our equipment with tougher foam materials
The insights gained directly influence our machine designs, leading to improved energy efficiency, faster processing, and higher-quality compacted blocks.
EPP Material Trials: The Results
The trials delivered key data about our compactors’ capabilities when processing EPP:
- Throughput: Handled approximately 200 kg (440 lbs) of EPP per hour
- Density of Compacted Blocks: Achieved approximately 350–400 kg/m³ (771–881 lbs)
- Compaction Ratio: A highly efficient 9:1, ideal for reducing storage and transport requirements
The resulting compacted blocks are easy to stack and store, enabling businesses to save space and reduce on-site collections, leading to significant cost reductions.
Unlike EPS, EPP doesn’t naturally bond during compaction unless melted, which makes pre-crushing and precision compaction critical. Our systems successfully handled these challenges, offering a robust, space-saving solution for EPP producers.
Smarter Recycling Solutions for a Sustainable Future
As sustainability expectations grow, businesses need efficient ways to manage complex streams like EPP.
At Greenbank Recycling Solutions, we’re proud to support the circular economy by helping organisations recycle, reuse, and even monetise their EPP.
Our goal is to design cutting-edge, easy-to-use compactors that enable customers to reduce volumes, lower carbon footprints, and turn disposal costs into revenue opportunities.
