Re­cy­cling of glass proves a bright idea

Central Otago Mirror - - CENTRAL NEWS - By JES­SICA MAD­DOCK

The Ban­nock­burn Ho­tel is crush­ing the thou­sands of bot­tles emp­tied in its bar and us­ing them to pave the car park, the beer garden walk­ways and to cre­ate a sparkling wa­ter­fall. Owner Tim Hanna said it was a disgrace the Cen­tral Otago District’s re­cy­cled glass was carted to Auck­land. The glass gen­er­ated by his ho­tel would in­stead be crushed and used to re­place shin­gle on the car park and walk­ways. The glass-crush­ing ma­chine smoothed the edges so it was com­fort­able to walk on. Crushed glass would also be sprayed on to the wall be­hind a wa­ter­fall in the ho­tel’s garden, to cre­ate a re­flec­tive sur­face. "We can use a lot of ma­te­rial and use it pos­i­tively . . . have some­thing in­ex­pen­sive that works. "It looks bril­liant. It is ar­rest­ing to look at." The crush­ing ma­chine was owned by Cromwell busi­ness­man, Rory Alexan­der, who said there was a huge mar­ket for crushed glass. "We have up to 27 dif­fer­ent uses." Crushed green glass had been used in­stead of grass at a prop­erty in Alexan­dra’s Molyneux Park sub­di­vi­sion, tak­ing the pres­sure off the owner’s water bill for ir­ri­ga­tion. Drive­way con­trac­tors, artists and can­dle-mak­ers were also buy­ing the crushed glass, along with peo­ple who used it in­stead of peb­bles in their aquar­i­ums, Mr Alexan­der said. There was also de­mand from coun­tries where crushed glass was not avail­able, such as Malaysia and in the Mid­dle East where it was sprayed against walls. A Malaysian ho­tel chain had wanted 70 tonnes of green beer "stub­bie" glass which matched the com­pany’s cor­po­rate colours, but the amount was larger than Mr Alexan­der could han­dle. "Ninety per cent [of the or­der] would have been profit." A large road­ing con­trac­tor was also in­ves­ti­gat­ing us­ing crushed green glass cov­ered with resin on Christchurch’s cy­cle­ways. Not enough glass was be­ing crushed in New Zealand to meet domestic needs, Mr Alexan­der said. Swim­ming pool op­er­a­tors through­out the coun­try were im­port­ing it from Bri­tain, as it made pool fil­ter­ing sys­tems more ef­fec­tive. Mr Alexan­der used bot­tles he col­lected from lo­cal pubs and glass dropped off to him by res­i­dents. The crushed prod­uct was sent as far afield as Auck­land.
