The clean chim­ney

Element - - Contents -

You may have no­ticed, while driv­ing along the south­ern mo­tor­way, that the chim­ney on the Pink Batts fac­tory has changed. It is, in fact, a new wet elec­tro­static pre­cip­i­ta­tor, which sucks 85% of the PM10 emis­sions (those com­ing from diesel ve­hi­cles and in­dus­try of this kind) out of the ex­haust. It ist as man In­su­la­tion’s $4m con­tri­bu­tion to the air qual­ity of the city, which reg­u­larly ex­ceeds ac­cept­able lev­els of PM10. “Any re­duc­tion of Auck­land’s dirty air is a good thing,” says tony Te Au, gen­eral man­ager of tas­man In­su­la­tion. “And as a large man­u­fac­turer, we have a re­spon­si­bil­ity to do what we can to im­prove the air qual­ity of our city.”
