Methyl Bro­mide re­cap­ture on track

New Zealand Logger - - Forest Grower’s Research 2018 -

A TAU­RANGA BIOSE­CU­RITY COM­PANY may have an an­swer to the prob­lem fac­ing forestry, which has been look­ing for a re­place­ment for Methyl Bro­mide be­fore the log fu­mi­gant has to be phased out in 2020.

By then, Methyl Bro­mide use will need to stop al­to­gether or a suc­cess­ful way of fully re­cap­tur­ing the ozone-de­plet­ing gas found so that it can con­tinue to be used for fu­mi­gat­ing ex­port logs.

To date, no sys­tem has been built that can re­cap­ture 100% of the gas, but Tau­ranga com­pany, Gen­era, has de­vel­oped one that has been proven to be up to 95% ef­fec­tive.

Mark Self, CEO of Gen­era Group, told the 2018 For­est Grow­ers Re­search con­fer­ence in Tau­ranga last month that it would be im­pos­si­ble to cap­ture the re­main­ing 5% be­cause it is caught up in the log and bark, and takes time to be re­leased.

He sug­gests that of­fi­cial ap­proval be sought for the re­cap­ture of 90% of Methyl Bro­mide as an op­tion for meet­ing the re­quire­ment. Mean­while, the in­dus­try is also wait­ing to hear if a sub­sti­tute chem­i­cal, called EDN, will be ap­proved for fu­mi­ga­tion.
