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

BKL-MACHINE at CHINAPLAS 2025, Booth 6B61 Shenzhen
Two machines on one stand aimed at two entirely different buyers: the recycler who takes in waste, and the film plant recycling its own trim.

Where the Numbers in These Guides Come From
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.
Washing lines
Machines commissioned before they ship
Lines are assembled and run in our own workshop in Zhangjiagang before dispatch. Water consumption of 4–15 m³/h and output moisture below 1% are figures from commissioning, not from a catalogue.
About the factory
One workshop, since 2015
BKL-MACHINE has built recycling machinery since 2015 from a 2,500 m² workshop with 300 m² of offices and a team of 40+, with lines delivered to more than 20 countries. Where a guide quotes a number we cannot source, it says so.

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.
- 19
- Guides and company posts published so far
- 5
- Waste streams covered end to end: PET, rigid HDPE, PP woven, film, regrind
- Own data
- Operating figures come from lines we commissioned, not from catalogues
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.
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.
When the reading is done, start from the material
Articles explain how a stage behaves. These pages turn that into a machine list for your own waste stream.
