Purcell: A Renewable Cellulosic Composite Material Can Replace Established GRP Construction Components

Considerable amounts of glass-fiber reinforced plastics (GRP) are used in many constructions and construction components. But although 250,000 tons of end-of-life GRP waste materials are currently produced annually, no practical solution has been found that would enable true recycling of GRPs. At the moment the only technically applicable concept entails thermal processing and the use of the remaining glass-fiber waste products after pyrolysis as an additive to cement. There is definitely no recycling, in the true sense of the word.
The urgency of the recycling problem is being accelerated by statutory regulations, which force manufacturers to take their products back.
