HDPE and Rigid Plastic Recycling Guides

Whole items that have to be broken down before they can be washed, and each form enters the line differently.

Start from your waste

Pick the material you have. Each guide covers what that waste stream does to a line, and which stages it can skip.

How we know

Where the Numbers in These Guides Come From

Complete plastic washing line assembled in the BKL-MACHINE workshop Our own parameter tables, not brochure figures Throughput, installed power, footprint and manpower in these guides are read off the specification sheets for machines we build. A rigid washing line at 1,300–1,500 kg/h draws 180 kW installed; the same line at 200–300 kg/h draws 100 kW. Both come from one table, which is why the ratios do not flatter the small line.

How to read this library

Four questions that come up before anyone opens the first guide. If yours is not here, the form below reaches an engineer rather than a mailbox.

Ask an engineer

Which guide should I read first?

Start from the material you actually collect rather than the machine you have in mind. Each material guide follows one waste stream through a line and marks the stages it can skip, which removes most of the catalogue before you look at a single model number.

My feedstock is a mix of several of these. Which guide applies?

Read the guide for the dirtiest and the bulkiest fraction you receive, because those two set the machine list. A line sized for muddy film will handle clean offcut; the reverse is not true. Where the mix changes week to week, the honest answer usually involves sorting before the line rather than a bigger machine inside it.

Do these guides still apply if I buy equipment from another supplier?

Yes. The process boundaries are physics rather than brand: flake size, moisture limits, contamination thresholds and water demand behave the same whoever built the machine. Use the figures as questions to put to any supplier you are comparing.

How current are the figures quoted in the guides?

Operating figures come from lines we have commissioned and are revised when new commissioning data contradicts them. Where a number is an industry planning range rather than a measurement from our own machines, the text says so on the spot instead of presenting it as a guarantee.

Still deciding

Tell us what you are recycling, not what machine you think you need

Photographs of the bales and the output grade you intend to sell tell us more than a model number. We will come back with the stages your material actually needs.

  • 01The material as it arrivesBaled, loose, wet, muddy or already sorted. A phone photo beats a written description.
  • 02What you intend to sellWashed flake, regrind or pellet decides how far down the line the investment has to go.
  • 03The question you are stuck onWhichever guide brought you here, tell us the part that did not resolve.
Ask Before You Buy An engineer replies

Ask the awkward question. What your buyer rejects flake for is usually a better starting point than a machine model.

A straight answer, even when the answer is that you do not need the machine.
