AMA recycling technologies develops and builds recycling machines for the reprocessing of hard plastics.
AMA was founded in 2007 with the aim of further refining waste streams from recycling processes into usable raw materials. This was quite a challenge and several successes have been achieved over the past 15 years. We have integrated the new techniques developed into our own factory (annual capacity 10,000 T). As a result, the techniques were extensively tested and at least 6,000 production hours were spent before the final version could be released for sale.
The machines developed in this way have been developed by people who have been earning their living for more than 25 years in the hard production environment of recycling and where a chosen solution must really be a good and workable solution. This has led to machines that are efficient, maintenance friendly, durable and affordable.
Introduction to the recycling of hard plastics
Mixed hard plastics are recyclable. In many cases, a few basic techniques are sufficient to make a good sorting. Important parts of the reprocessing are washing, drying and, if possible, sorting by density. However, some plastics have an equal or overlapping density, here other techniques have to be used in order to sort these mixtures anyway. This knowledge makes it possible to divide the recycling process into two parts, namely the washing and sorting by density and the sorting of mixtures with equal or overlapping density.
About washing and sorting by density
Washing and sorting on density is done in a sink-float tank. This is where the plastic is introduced, after which it is continuously submerged by the paddle wheels so that the density separation can take place. The plastic is also washed in this way. The sinking fraction is transported through the extraction screw to a high efficiency centrifuge where the plastic is intensively dried. After this, the plastic can be bagged. The floating fraction follows a similar path. A combination of several sink-float tanks makes it possible to sort at different densities. The density of the liquid in the sink-float tank determines the separation. For this process at least one sink-float tank, two high efficiency centrifuges, one vibrating sieve and two big bag filling stations are required. In addition, some peripherals are needed to complete this whole as a production line.
About sorting of mixtures with equal or overlapping density
If the density of the plastics is the same or overlaps, it must be sorted differently. A reliable technique for this is tribolelectric sorting. With this technique, the plastic particles are charged with each other by means of friction and then sorted in an electric field. This technique is insensitive to the colour of the plastics and can produce up to 99% pure plastic streams. For this process, the plastics from the high efficiency centrifuge are further dried and then stripped of rubber and wood by means of the rubber wood separator. The plastic is then fed into the Triboelectric plastic sorter where the sorting takes place. The sorted streams are then bagged. This process requires at least one Triboelectric plastic sorter and two big bag stations.
Our modular concept, order the parts and build your own line
Sink-float tank with integrated high efficiency centrifuge, a simple but efficient solution for a compact washing line. Completely in stainless steel 304 and suitable for fresh or salt water.
High efficiency centrifuge
Completely redeveloped high efficiency centrifuge based on our many years of production experience with the predecessor of this centrifuge, we have made various improvements with regard to maintenance costs, downtime and wear and tear parts.
Vibrating sieve to filter the process water.
Process water is preferably used in a closed circuit. The authorities also see this as the ideal solution. Obtaining the permits for a recycling plant is greatly simplified by the use of a closed circuit and the costs of using the plant are significantly lower.
Triboelectric plastic sorter
Electrostatic sorting of black and colored plastics is possible with this machine. Mixtures of 2 or 3 mixed plastics can be sorted successfully. In the premium model even in one step. In this way intermediate storage of the residual material and the reprocessing is not longer necessary.
Rubber wood separator
Post-consumer plastics are often contaminated with wood, rubber and small metal particles. A final product with a few percent of rubber and wood is often not sold or can only be sold at a low price. Our rubber wood separator can greatly reduce the proportion of wood and rubber and in some cases the wood can be completely removed. In this way products can be made that fall within the tolerances of the clients.
Big bag filling station
Big-bag filling units are suitable for filling commercial sizes of big bags. Products are metered into the big bag, for example via metering screws, rotary valves or hopper feeder. Fully automated big bag loading with shaking mechanism to assure evenly loaded bags.
Complete lines with or without triboelectric separator
An example line suitable to separate on one density. Equipped with a closed water circuit, simple water purification, two centrifuges, two big bag stations and of course the heart of the installation, the sink-float tank. All this together with the necessary peripherals to finish everything. A simple and affordable installation to start washing plastics.

The material stream is evenly fed onto an acceleration belt by means of a vibrating feeder. At the end of this acceleration belt there is a location-resolving, inductive metal detector (all-metal sensor, area sensor) under the conveyor belt. This metal detector / sensor can reliably detect all metal particles from a size of approx. 1-2 mm. All metal parts means, in fact, all metal parts: VA (stainless steel), copper – also cables, Fe (iron), aluminium, brass, lead, zinc…. . By means of our highly effective and fast electrodynamic separators (flippers, flaps), these metals are certainly removed from the material flow.
