Question 1

What output quality should I expect from a plastic washing line?

Accepted Answer

Output quality targets vary by intended end use. For recycled PE film pellets destined for refuse sacks or agricultural film: typical targets are below 300 ppm non-polyethylene contamination and below 1% moisture after drying. For recycled HDPE bottle flake for blow moulding: below 100 ppm contamination, moisture below 0.5%. For recycled PET flake for bottle-to-bottle applications: below 50 ppm contamination, moisture below 0.2%. Achieving these targets requires appropriate line design, process water quality management, and consistent input material sorting. Confirm with the machinery supplier what output contamination level their line is designed to achieve with your specific input material.

Question 2

How much space does a plastic washing line require?

Accepted Answer

A small washing line producing 500 kg/hour typically requires approximately 300–500 m² of floor space including the infeed area, washing section, and output storage. A medium 1,500 kg/hour line requires approximately 600–1,200 m². Allow additional space for bale storage, water treatment tanks (which are often located outside the main building), pelletiser, finished product storage, and forklift access routes. Confirm the footprint with the machinery supplier and request a layout drawing before planning the facility.

Question 3

What is the typical payback period for a plastic washing line investment?

Accepted Answer

Payback period depends entirely on your local market — the spread between your input waste plastic cost (or collection cost) and the value of your clean output pellets or flakes, your throughput utilisation, and your operating costs (labour, energy, water, maintenance). We cannot quote specific figures. The economic case must be built on your local market pricing and operating cost data. Request an operational cost analysis from the machinery supplier based on your planned throughput and ask for references from comparable operations in similar markets.

Question 4

Which countries manufacture plastic washing lines?

Accepted Answer

China is the dominant source for plastic washing line equipment globally — manufacturers in Zhangjiagang (Jiangsu), Changzhou, and Qingdao specialise in washing lines, friction washers, and complete recycling systems. European manufacturers including Herbold Meckesheim (Germany), Sorema (Italy), and Previero (Italy) produce premium washing lines for demanding applications. Austrian-based EREMA and Starlinger are global leaders in full-system integration including washing and pelletising for bottle-to-bottle quality output. Chinese lines are price-competitive for standard applications; European systems are preferred for high-purity output or applications requiring tight process control.
