▁dram atic ▁increase ▁in ▁global ▁wind ▁energy ▁generation ▁will ▁require ▁installation ▁of ▁a ▁newer ▁and ▁larger ▁fleet ▁of ▁more ▁efficient ▁wind ▁tur b ines ▁and ▁the ▁consequ ent ▁de comm ission ing ▁of ▁ag ing ▁ones . ▁Based ▁on ▁a ▁study ▁carried ▁out ▁by ▁the ▁European ▁Wind ▁Energy ▁Association , ▁in ▁the ▁year ▁ 2 0 1 0 ▁alone , ▁between ▁ 1 1 0 ▁and ▁ 1 4 0 ▁kil ot ons ▁of ▁compos ites ▁were ▁consum ed ▁by ▁the ▁wind ▁tur bine ▁industry ▁for ▁manufact uring ▁bl ades . ▁The ▁majority ▁of ▁the ▁bla de ▁material ▁will ▁eventually ▁end ▁up ▁as ▁waste , ▁and ▁in ▁order ▁to ▁accommod ate ▁this ▁level ▁of ▁composite ▁waste , ▁the ▁only ▁option ▁is ▁rec y cling . ▁Typ ically , ▁glass - f ib re - re in for ced - pol ym ers ▁( G FR P s ) ▁compose ▁of ▁around ▁ 7 0 % ▁of ▁the ▁l amin ate ▁material ▁in ▁the ▁bla de . ▁G FR P s ▁h inder ▁inc iner ation ▁and ▁are ▁not ▁comb ust ible . ▁Therefore , ▁conventional ▁rec y cling ▁methods ▁need ▁to ▁be ▁modified . ▁Currently , ▁depending ▁on ▁whether ▁individual ▁fib res ▁can ▁be ▁recovered , ▁there ▁exists ▁a ▁few ▁general ▁methods ▁for ▁rec y cling ▁G FR P s ▁in ▁wind ▁tur bine ▁bl ades : ▁ ▁Mechan ical ▁Rec y cling : ▁This ▁method ▁doesn ' t ▁recover ▁individual ▁fib res . ▁Initial ▁processes ▁involve ▁sh red ding , ▁cr ushing
