The use of GRP waste in concrete contributes to cost savings
associated with waste handling, transport, storage and landfill tax
payment. GRP waste substitution to fine aggregates in concrete
should save approximately 15% of the fine aggregate cost (substitute
to sand). Currently, almost all the GRP waste in United
Kingdom is sent to landfill and the landfill tax for non hazardous
waste is being raised from the current rate of £32/tonne by £8/year
until 2010/2011 [30]. GRP waste recycling is a viable option to help
with the UK 2007 waste strategy target of 50% waste reduction by
2012 in waste disposal to landfill.
