Paprec VS Veolia

Comparison of two treatment WEEE plants

Management of Waste Electrical and Electronic Equipment is regulated by Directive 2002/96/EC, which sets the following goals:
• 4 kg of WEEE separately collected per year per inhabitant
• Reuse and recycling between 50 and 80% of the weight of the equipment,
• Recovery of between 70 and 80% of the weight of the devices.

presentation

VALDELEC PAPREC is a factory specializing in the dismantling of WEEE. There are four processing platforms including one located in Chambery. The company specializes in the manual dismantling of WEEE. The sorting of the individual components allowsorientation of recycling specialist.

presentation

The all-new plant-Clean Veolia treats four categories of electrical and electronic waste (WEEE) and GEM (white goods cold), PAM (mixed small devices), monitors (LCD, plasma, CRT) and  professionals waste.

Recycling rates

For gray goods (WEEE computer and office), the average recycling rate of 75% is greater than the statutory rate which is requiredby 65%. In detail, a unit is recycled to 98% (all components combined), a CRT (TV or computer) to 80% (this is easily done since the glass plate is 40% recyclable by weight of the unit).

Recycling rates

Valuing is above the regulatory objectives: 88% against 75% according to the decree. The electronic boards are not processed atthe plant but sent to specialized recyclers. These are some 26,000 tonnes of WEEE being treated per year. Overall, 90% by weight of PC is upgraded, the rest is almost completely recovered as energy.

Examples flat panels

To date, there is no technical process to dismantle and recycle flat screens compounds (televisions or computers). This technologyis recent, there is not enough WEEE tonnages (flat panels represent 5% of total treated screens) that would justify investment in processes for reprocessing. Flat screens contain indium oxide which is not currently recyclable. The solution today is heat treated toneutralize components (grinding is not possible because of certain hazardous compounds).

Recycling of screens

the dismantling of the screens is manual and takes about 5 minutes for a CRT monitor against from 20 to 25 minutes for a flat screen. These currently account for only 5% of treated screens. In terms of CRT tubes are recycled in closed loop since there is stillan Asian market for this type of screen. All plastics are not recyclable: for thermoset (epoxy resins), for example, only the energy recovery is possible. By cons, in terms thermoplastics, the process is reversible and it is possible to enhance the material

I think

This plant has limitations and difficulties in implementing a recycling of WEEE. The legislation is more restrictive but the control of contractors is not easy, especially when the level of outsourcing increases, which is often the case. In addition, the mixing of differentplastics for example, and the use of hazardous substances penalize waste and reduce their value.

I think

the difficulties of this plant:
Insufficient supply (this confirms the numbers of ADEME on the rate of WEEE recycled now)
Complexity of devices (many pieces, many materials) that make recycling more difficult
Little dialogue with manufacturers to facilitate recycling, it seems that eco-design stops short of taking into account a significant improvement in recycling
