Con­crete plans for tired tyre moun­tains

Central Leader - - SITUATIONS VACANT -

New Zealand’s moun­tains of used tyres look set for a sec­ond lease of life - as ce­ment, rub­ber un­der­lay and sound proof­ing.

En­vi­ron­ment Min­is­ter Nick Smith has an­nounced a plan that will see old tyres shred­ded, then turned into other uses, while lim­it­ing the amount of stock­piled tyres.

‘‘New Zealand has a long­stand­ing prob­lem, with five mil­lion waste tyres gen­er­ated each year,’’ Smith said.

‘‘We have dozens of tyre stock­piles around the coun­try pos­ing a fire risk, leach­ing con­tam­i­nants, pro­vid­ing a breed­ing ground for ro­dents and in­sects, and blot­ting the land­scape.’’

Un­der new pro­posed en­vi­ron­men­tal stan­dards, tyre stock­piles of more than 200 cu­bic me­tres - about 2500 tyres - would be banned if they did not have coun­cil con­sent.

The gov­ern­ment would pay Waste Man­age­ment New Zealand $3.8 mil­lion to set up a na­tion­wide tyre col­lec­tion net­work, as well as tyre shred­ding fa­cil­i­ties in Auck­land by the end of 2017.

Shred­ding tyres would make trans­port­ing them more eco­nom­i­cal, Smith said.

Mean­while, Golden Bay Ce­ment had been granted $13.6m to­wards tech­nol­ogy to use old tyres in the man­u­fac­ture of ce­ment, by us­ing the rub­ber to fuel kilns and the steel in tyres in­side the ce­ment.

‘‘The ma­jor en­vi­ron­men­tal gain from this ini­tia­tive is a sol- ution for mil­lions of waste tyres, but there is also a ben­e­fit in re­duced green­house gas emis­sions,’’ Smith said.

A fur­ther $1.2m in grants was be­ing given out for projects in­clud­ing cre­at­ing rub­ber gran­ules for rub­ber un­der­lay.

New reg­u­la­tions will mean tyre stock­piles of about 2500 tyres will be banned if they do not have coun­cil con­sent.
