MRF Light packaging
The main objective of lightweight packaging sorting and selection plants is the recovery of recyclable materials and the reduction of rejects sent to landfills. These facilities, as in the case of mechanical pretreatment of municipal waste, can be fully automatic, semi-automatic, or manual.
Automatic selection and sorting facilities for MSW to recover valuable by-products with high commercial value
Automatic material separation
They use advanced technology (optical separators, magnets, and eddy currents) to classify plastics by polymer, ferrous and non-ferrous metals, and paper-cardboard.
Cleaning and removal of impurities
They filter out materials that do not belong to the recycling stream or that are contaminated, ensuring that the resulting raw material is of high purity.
Compaction and logistics
They press the already sorted materials into high-density bales, which optimizes transport to final recyclers and reduces the carbon footprint.
Energy recovery
They identify and divert non-recyclable materials for transformation into Solid Recovered Fuel (SRF), preventing them from ending up in landfills.
The degree of automation of the facility is determined by various parameters: number of fractions to be recovered, their degree of purity, nominal plant capacity (taking into account the low density of LWP), and minimum reject production requirements, as well as labor savings. Bianna designs and manufactures the main equipment for these facilities (bag openers, ballistic separators, trommels, pneumatic material collection systems, conveyor belts, bottle piercers, etc.) and integrates the best available optical separation technologies, or screening, glass separation, and magnetic and inductive separation technologies. Or, if the project requires it, SRF production lines for optimal process efficiency.

De residuo
Type of waste entering the plant
This type of plant treats waste from source-separated collection systems, mainly composed of mass-consumption packaging. The input flow integrates highly valuable materials such as polymers (PET, HDPE, LDPE, and PP) and beverage cartons. Likewise, the waste includes a significant presence of ferrous and non-ferrous metals, along with paper and cardboard fractions. These are materials that require precise separation to guarantee purity levels that allow their reintroduction into the production cycle.

Operation
A synchronized process to maximize recovery
The process in a Lightweight Packaging (LWP) treatment line is structured through the synchronization of our key machinery:
- Opening and Feeding: the process begins with the Bag Opener (OC Series), which achieves 95% efficiency by releasing the packaging gently so as not to damage the recoverable materials.
- Primary Screening: large stationary Trommels separate the material by size (removing fines and organic matter), preparing the flow for subsequent phases.
- Ballistic Separation: the main flow reaches the Ballistic Separator, whose inclined ramp of moving paddles automatically separates planar materials (2D) from rolling materials (3D).
- Optical Selection and Aspiration: very high-speed conveyors (PLS Series, at 3 m/sec) spread the material toward optical separators. Simultaneously, Automatic Aspiration Systems extract all LDPE plastic (film) from the material drops.
- Final Conditioning: by-products such as plastic bottles pass through our Bottle Piercer, which removes the internal air by means of a cut, thus ensuring perfect pressing and baling.
