The plant reclaims polyolefin thermoplastics scraps to be transformed into granules with an output of 10 Tons/h.
The thermoplastic scraps come from the urban and industrial separate collection and they are previously selected as:
HDPE / PP containers and bottles for foods.
HDPE / PP containers and bottles for detergents and chemicals.
Plastics at inlet: HDPE and PP (75%), heavy plastics (25%).

AMUT designers usually work in collaboration with the technicians joining their efforts to develop performing machines and proper structure in terms of optimisation of the overall dimensions and of an easy handling to facilitate the maintenance interventions.

The main washing action on the product is made by the Friction Washer, thanks to the intensive friction of the rotary paddles among the flakes. Even if it is continuously fed, the friction washer allows an adjustment of the stay time of the material.
A characteristic of this unit is its noiselessness, therefore a soundproof box is not required.
The water, coming from the friction washer with paper pollutants, is filtered and then used again for the process.
After this strong washing action, the rinsing cycle starts into two proper troughs in series where there is also the separation of light pollutants (paper, non-polyolefin thermoplastics, etc.). The material is introduced in the bottom of the rinsing troughs in order to improve their efficiency.

The light pollutants are so decanted, while the polyolefin float. Also these rinsing troughs are equipped with an automatic extractor of decanted material and heavy plastics. This mixed plastics are dried by a centrifuge and stored in big bags.
The Washing Section operates in a fully automatic cycle, controlled by a centralized board.
The equipment has been designed to assure both separation and complete cleaning of thermoplastic material from all the pollutants having specific weight higher than the thermoplastics one.
Possible residuals of pollutants, not extracted in the Washing Section, will be filtered during the process in the Granulation Section.

Once all materials are selected, they are stored into the storing unit by type, ready to be discharged in the collecting conveyors to be then sent to the baling press, for the final packaging of bales.

In the field of the recycling plants for thermoplastic materials coming from urban and industrial collection sites, AMUT has developed recycling plants consisting of a series of modular components which can be combined matching the features of the product to be recycled and are tailored according to the Customers’ specific requirements.



AMUT washing and granulation technology can process the following materials:
• plastic films for packaging
• agriculture films
• HDPE bottles and containers
• battery boxes

AMUT supplies turn-key plants starting from the elaboration of the project up to the erection and start-up at the Customer’s factory. Such plants are fully automated and controlled by PLC and supervision PC with electronic synoptic complete of all the
working parameters.
