How to assess contamination in recycled plastics before complaints or machine failures occur
🎓 Online course for laboratories, quality departments, purchasing and sales of recycled plastics
Have you ever received a regranulate that looked fine, but during processing you encountered sudden pressure spikes, clogged filters, or defects in the final product?
👉 The filtration index is the one parameter that reveals hidden contamination before it causes problems on the production line.
👉 And for companies selling regranulate – it’s a key proof of quality that builds client trust and speeds up purchasing decisions.
This course shows you how to analyze filtration test results, what types of equipment and methods are available, and how to use this data in practice – both on the supplier and the processor side.
What will you learn in this course?
🟢 How the filtration index test works and which data really matters
🟢 How to interpret results: pressure build-up, filtrate mass, test duration
🟢 What types of equipment are used – and how they differ
🟢 How to compare batches of recyclate based on filtration results
🟢 How to use test data in supplier evaluation or sales negotiations
🟢 How to present filtration results to prove material quality and reduce returns
Who is this course for?
🟢 Labs and quality control teams in companies processing recyclate
🟢 Recycling companies that want to better document material quality
🟢 Buyers and salespeople working with regranulates and regrinds
🟢 Manufacturers of film, pipes, profiles and packaging who can’t afford line stoppages
What kind of equipment is covered in this course?
This course presents typical technical solutions used across Europe:
🟢 Laboratory extruders with filtration heads and pressure sensors
🟢 Compact devices dedicated to recyclate filtration testing
🟢 Test lines used by large recycling plants and external laboratories
You’ll learn what options are available on the market, what a typical testing procedure looks like, and what to pay attention to in technical documentation.
Why is this course worth your time?
➤ Because the quality of regranulate is not only about colour, smell, or how it looks "at a glance"
➤ Because contaminated material can cost your company more than a filtration test ever will
➤ Because if you sell recycled plastics, filtration results give you a competitive edge with customers
