The Coriano plants were built for the purpose of separating impurities consisting of foreign fractions present in the separate collection of the vitreous fraction. These impurities are identified as metals, plastic, paper, wood, infusibles, unbreakable glass, etc. The construction of the plant is aimed at obtaining glass output that meets CoReVe specifications. The construction of the plant was conducted in record time: four weeks on site and two months of supplying the machinery since the project was approved to see the plant up and running.

The project consists of the components summarised below:

vibrating channel with an 8 m³ hopper, installed to feed the line with a robust machine that does not create clogging and crushing problems;

backhoe loader conveyor, delimited to prevent access under the machine during operation, given the hazardous nature of the material handled

sorting belt fitted with speed variator that can be controlled by the operator if the line requires speed regulation or there are sorting needs, without causing stoppages to the line;

Safety rope that allows the machine to stop along its entire length;

Pre-fabricated sorting cabin with 4 sorting workstations;

stainless steel connection belt being located under the deferrization belt;

magnetic sorter with hoisting system (electric hoist);

magnetic sorter with hoisting system (electric hoist);

glass outfeed conveyor.

The increasing focus on sustainability has pushed companies to find alternative solutions for the recovery of natural resources. Since the 1980s, PAL has been engaged in technological research for cleaning recycled wood. I In Portugal, PAL Green Division designed and built in 2018 a waterfall cleaning tower that integrates state-of-the-art technological and innovative machinery in a small area.

The system is able to process 40 t/h of recycled wood for chipboard production. The plant is equipped with two Cyclops for the cleaning of ferrous, non-ferrous and heavy pollutants, one operating in the micro and one in the macro fraction, in addition to the use of technology for cleaning the fine fraction. These are optical solters with very high efficiency and continuous operation for the removal of any pollutants such as plastics, metals and aggregates.

The CSS production line is fed by three different flows from two separate plant sections.

• The first flow - SOV1: under-screening with a size greater than 80 mm at the outlet originating from the pre-treatment system of the OFMSW (Organic Fraction of Municipal Solid Waste) that has not yet undergone digestion.
• The second flow - SOV2: underscreening materials of more than 80 mm deriving from the sorting of processed material through composting that underwent bi-oxidation accellerated in two stages: the first in a forced aeration bio-tunnel; the second on an similarly aerated floors, for a total treatment time of 25-29 days.
• The third flow - SOV3: under-screening materials of more than 40 mm delivering from the sorting of material exiting the bio-tunnels belonging to the new aerobic composting section.

The new line, built by PAL, can be fed through the existing line (SOV3) or through a special loading hopper using a wheel loader (SOV1 and SOV2). The plant was designed to have a certain degree of flexibility thanks to the bypass system, that allows the better manage any downtime due to maintenance.

PAL Green Division was awarded the contract for the construction of an automated waste sorting plant in Tolentino, Macerata province, specifically for paper, cardboard and light multi-material.

The following equipment was supplied for the project:

• 1 Bag taering equipment
• 2 Magnetic separators
• 2 Induced current separators
• 3 Optical sorters
• 2 Rotaring drum screens
• 1 Double-stage ballistic screen
• 2 Sorting cabins
• 1 Baling press
• 40 conveyors
• 130 ton of steel structures

Moreover, the contract includes the supply of all connecting conveyors between the machines, the mechanical installation, the supply and installation of the switchboards and the on-board wiring, and the extraction system. The sorting process for both types of material will take place in the same production area.
