Fibre reinforced polymers (FRPs) are increasingly being used in construction owing to their light weight, ease of installation, low maintenance, tailor-made properties, and corrosion resistance. The UK FRP industry produces 240 000 tonnes of products a year, with 11% of this being for the construction industry. This best practicable environmental option (BPEO) guide provides information on the disposal and recycling options available for FRP waste, uses of FRP recyclate, ecocomposites, and composite recycling facilities. The aim is to enable the construction industry to make informed decisions about material choices at the specification stage, consider factors to enable easier deconstruction at the design stage and assess the relative merits of the disposal options available at the end of the service life. The guide gives details of legislation which will impact on choices for material re-use, recycling or disposal, discusses research into the recyclability of FRP building materials, describes products that can be manufactured from FRP recyclate, and presents a financial assessment for disposal and recycling options. 47 pages.
