Our products

Product category: Recycling plants for mixed waste


A friction washer or friction separator is a water high-speed cleaning machine for mixed plastics. The system cleans the materials with a high contamination or persistent dirt, for instance, PET and film flakes. Ideally, our friction washer follows both the hot washer as a rinsing unit in the plastic recycling process.

A PET hot washer, is an indispensable piece of equipment for any plastic recycling industry. Also known as a plastic hot wash machine, it produces recyclables requiring food grade or high-quality grades. Adding this machine to the washing line of plastics such as PET, HDPE, PP/PE, etc., removes contaminants. Materials such as adhesives, scrap label remnants, drink and food residues and odor will be removed.

Applying a sink-float tank is one of the most valuable separation techniques in recycling systems. We also see descriptions in the industry such as separation tank or float sink separator. The tank is filled with water and, depending on the materials to be separated, additives to alter the fluid’s density.

The mixed plastic stream is dosed into the tank where high-density materials will sink, and low-density materials will float. The separated particles will be recovered and conveyed for further processing.

A dry cleaner is a machine designed by B+B that serves the purpose to pre clean plastics waste from sand, stones, glass, paper, etc. This method is very sustainable because it requires no addition of water and is low in energy consumption.

Practice shows that a combination of this cleaning unit for plastics followed by the zig-zag air classifier results in a 90 - 95% separation of contaminants, without the plastics coming in contact with water or cleaning solution.

A Zig-zag air classifier divides a mixed material stream into two homogeneous streams. The upward vacuum extraction ensures the lighter micronized materials to blow up to exit the sorting chamber separately, leaving the heavier materials to exit at the bottom.

For a higher quality performance, B+B builds classifiers by placing multiple units in a circular arrangement. The material is evenly distributed via a plate ensuring a higher throughput.

Important part of recycling plastics is a dewatering process and subsequent drying process. B+B designs and supplies a combination of innovative vertical dewatering equipment and a dry system named step dryer.

Residual moisture levels in the range of 0.4 - 0.06 wt% can be attained for thermoplastic granules in virgin production processes such as polycarbonate, polyethylene, polyamide, polypropylene, and polystyrene. Our engineers can aim for even lower numbers upon request.

Thermal dryer units are the logical subsequent step in the plastic recycling process which follows the mechanical drying stage. Drying through dehydration will reduce any residual moisture from the surface of plastic flakes (rigids or film) for the subsequent steps in the process, e.g. extrusion.

B+B builds and supplies these dryers, or air dryers, by implementing the heat exchangers from our sister company Geurts International. According to your requirements, we can design a system fueled by oil or gas, thermal oil, or electrically operated or utilizing hot air from another part of your production process.

To complete the washing line, a big bag filling station is the last step in the plastic recycling process offering perfect material handling.

B+B supplies automatic filling stations for big bags with the following options:

a choice of vibration or distribution mechanism
filling level control
fan to inflate the big bag
double or single design
dust extraction
optional integrated weighing scale
