T%e ost coon future issues relatable to PC is in its dis"osal "rocess. PC contains

as% after incineration. Currentl(' PC is res"onsible for about 20B to 30B of all cadiu

6ne of t%e "robles faced w%en tr(ing to dis"ose PC is t%e fact t%at it is non/
biodegradable. T%us' it cannot be bro+en down in atter of wee+s or ont%s a+ing it
i"ossible to be destro(ed naturall(. T%e global "roduction of PC currentl( stands at about 20

PC.
In t%eor(' PC are able to be rec(cled. T%is is done t%roug% a series of crus%ing'
grinding and elting "rocess. ;owever' t%ere are several constraints in t%e actual "rocess to
rec(cle PC.
6ne of t%e constraints in rec(cling PC is t%e need to sort t%e waste into generic
aterials. T%e level of i"urities is an i"ortant as"ect in deterining t%e ,ualit( of t%erec(clate. &-a"les of i"urities are ot%er "ol(ers and reinforceent aterials. T%us' it is
i"ortant to first deterine t%e co"osition of PC. ;owever' t%is is visuall( and ec%anicall(
i"ossible. T%is is due to PC waste streas norall( being a co"le- i- of aterials
coing fro various sources. T%is causes rec(cling of PC tec%nicall( and econoicall( ver(
difficult. ?ritis% Plastics $ederation states t%at PC based "roducts suc% as t%e das% board in a
car is unar+ed' fro a variet( of sources and in a for w%ere disassebl( would be ver(
costl( if not i"ossibleU.
PC also needs to be elted for it to be able to be rec(cled. T%e act of elting PC will
release %(drogen c%loride w%ic% causes ot%er s"litting "rocesses in t%e PC to s"eed u". T%e
"rocess is called autocatal(tic corrosion and causes t%e ,ualit( of t%e end "roduct to dro". T%is
is t%e reason as to w%( ost "rocess of rec(cling PC results in a downc(cling "rocess. !ue to
t%is' ost rec(cled PC is unsuitable for its original "ur"ose. ?ritis% Plastic $ederation states
t%at' t%e VdowngradingO nature of PC rec(cling "rocess liits t%e nuber of ties t%at it can be
rec(cled' eaning t%at t%e "roble of dis"osal is erel( "ost"oned.
Anot%er constraint is regarding t%e ar+et. Plastic rec(clate %as a ver( sall ar+et
deand. A re"ort on general "lastics rec(cling' Plastic and Rubber Jee+l( dated on 1**3
re"orts t%at "rocessors are reluctant to acce"t rec(cled aterialU and t%at it is clear t%at
unsubsidied rec(clate cannot reall( trade against virgin aterialU. Anot%er re"ort b( t%e ?ritis%
Plastic $ederation states t%at t%ere are serious restrictions in t%e ar+et o""ortunities for

In order to overcoe t%is "roble' t%e ?ritis% Plastic $ederation "ro"oses t%at a new

%eav( etals li+e cadiu and tin. T%us' it is i"ortant to bear in ind t%at t%is sort of rec(cling
%as no environental value.
Anot%er issue regarding PC rec(cling is t%at t%e "rocess itself results in eission.
;(drogen and benene is released during crus%ing and grinding. 6rganoc%lorines are released
w%en PC coating is burnt off co""er cables. PC a( also cause eissions of dio-in to
increase w%en it %as containated aterials during t%e aterialsO rec(cling "rocess. Accordingto ;MIP figures' dio-in eissions fro scra" etal wit% PC is relativel( %ig%erQ at about

T%e re"rocessing of "lastic industr( scra" creates less "robles co"ared to "ost/consuer

:ast but not least' t%e issues of t%e rec(cling and solid waste dis"osal %ave alread(

et%ods t%at used in t%e rec(cling w%ic% are incineration and rec(cling Patric+' 2005.

"ost/consuer waste is in its infanc(' as far as t%e "ol(er industr( is concerned. T%ere are
an( issues concerning collection' se"aration' and "rocessing into suitable a""lications. T%e
"riar( issue is' of course' t%e ca"ital costs associated wit% a rec(cling o"eration in co"arison

T%erefore' since t%e "robles %ave been occurred for a decade' soe coittee is
