"High-grade logs for furniture or parquetry is already frequently marked with numbered tags or radio tags. However, the partners in the project »Intelligent Wood - RFID in Timber Logistics« desire a more practicable solution that is suited for marking all types of wood – even the over 13 million cubic meters of industrial timber produced in Germany each year. Industrial wood is defi bered and processed into pulp, paper or composite wood panels. »Since the profi t margins in this sector are slight, the RFID transponders used may not cost much nor disrupt further processing of the wood,« the project manager Wäsche points out. Hence, the team at IZM has developed a new wood-based transponder: With the exception of its antenna, the tag consists of paper and lignin. Large quantities of the resin-like polymer are yielded when cellulose is extracted from wood. »The transponder‘s fraction of metal ist far below the typical levels of impurities in and around wood,« explains Christine Kallmayer, group manager at IZM..."
