What is your technology?
The Mini PRF, which improves the pre-sorting phase, delivering PET bottles with a low contamination rate and of a better quality. Placed at the inlet of a standard PET wash line, it has been developed by AMUT to overcome the problem of handling low-quality commingled bales.
How does it work?
The Mini PRF is a dry system which allows the pre-selection of bales in order to remove most contaminants such as paper, cardboard, fibres and debris. The clean PET bottles are then ready to go through the sorting and pre-washing plants.
Where would it ideally be used?
It is particularly suited to sorting systems where the contamination rate for collected bottles is more than 40%. The size of the Mini PRF is based on the capacity of the existing wash line.
How is it different?
AMUT developed the system to meet the emerging need of customers with municipal plants that were not able to assure the PET bottle quality standards requested by the market, such as the total removal of sleeves and other 2D elements.
What benefits does it offer?
The Mini PRF allows the operator to get the maximum value out of its post-consumer PET, reduces production costs and those associated with disposal.
In a dry phase, it eliminates most of the contaminants that occur in a standard wash line, which create a high volume of mud and wet waste, which in turn increases the ‘dump cost’.
Where has it been used?
A Mini PRF is running at Wellman’s Plastics Recycling in South Carolina, US.
This depends on the size and complexity of the task, such as the percentage of contamination and the type, so prices are from £169,000-£1.18m.
The main advantages of installing a Mini PRF before a classic wash line include:
- increasing the efficiency of near-infrared (NIR) sorters
- drastically reducing the wet waste volume, which saves money in disposal
- reducing the manpower needed to manually check and pick out waste before the NIR sorter.
If combined with the AMUT delabeller, which can peel off full body shrink labels, the yield could be improved by several percent.
What is its life span?
The equipment is engineered to work 24/7, and its expected life with adequate maintenance is more than 10 years.
What about maintenance?
The Mini PRF requires low maintenance and only sporadic intervention by the operators. The structure is built with sturdy materials and high-quality components made by reliable European suppliers.
How is it future-proofed?
The use around the world of PET containers for beverages and other liquids is growing. These days, there is a tendency to collect different materials in a single stream and then separate them in a clean MRF, which causes more challenges and poorer quality in the PET bales. The Mini PRF will become obsolete only when the quality of collected bottles becomes ‘perfect’.
