In Europe, almost 99% of the end-of-life (EOL) Cathode Ray Tubes (CRT) are disposed in landfills. The reason is that most of the recycling routes demand very tight material specifications whereas the composition of the glass from CRT is both non uniform and very special. Moreover, landfilling was the cheapest solution and there was no regulation concerning EOL CRT disposal.
The RECYTUBE project was launched, to tackle this issue with the following objectives:
- to develop a flexible and integrated technology to clean and sort end-of-life Cathode Ray Tube glass, in order to produce economically a high-quality Secondary Raw Material (SRM),
- and further to validate the feasibility of closed-loop recycling (i.e. producing new Cathode Ray Tube glass) and open-loop recycling (i.e. alternate recycling routes) of this SRM.
To meet these objectives, the RECYTUBE consortium has brought together representatives of each phase in the EOL CRT glass life cycle, namely: two glassmakers THOMSON VIDEOGLASS (FR) & SCHOTT (DE), a CRT manufacturer VIDEOCOLOR (IT), a manufacturer of automatic sorting equipment SEA (IT), a recycler of CRT glass factory rejects VALLONE (IT), a glass research centre SSV (IT), a university involved in material recycling UIAH (FI), and a waste and environment research centre, CREED-VIVENDI Group (FR).
Firstly, the end users' specifications for the closed-loop (both at SCHOTT and VIDEOGLASS) and open-loop applications (ceramic tiles, ceramic glazes, tableware and studio glass, construction blocks, glassfibres) were defined thus allowing the RECYTUBE technology to be designed.
With the first SRM produced by the RECYTUBE 'pilot process' at VALLONE, small scale tests have been carried out. Then the successful results of the small scale tests and the process optimization have allowed the performance of the full scale tests.
The successful full scale tests have then validated both the RECYTUBE technology and the closed-loop & open-loop recycling applications on the technical point of view.
It has to be noted that some few optimizations of the 'pilot process line' are needed and with such modifications, the RECYTUBE project/technology fully meet the technical objectives.
Concerning the environmental impact, the SRM production have lots of positive impacts : saving of raw materials and energy consumption and reducing the amount of wastes to be disposed of in landfills and they fully meet the environmental objectives of the RECYTUBE project.
Concerning the economical point of view, the optimized RECYTUBE technology cost could compete with disposal costs in most of the European countries. On the other hand the transportation cost has to be taken into account. It is quite evident that logistic situation is critical for right localization of a SRM production plant. Moreover, in order to reach the minimum process cost, quite high tonnage has to be treated by the SRM production plant. Indeed, the lack of input material is today one of the biggest critical aspects.
Thus a key element for any future development of a RECYTUBE plant is the improvement of both collection systems and legislative support (e.g. forbidding the disposal in municipal landfills and favouring cross-border transportation).
