Methyl Bromide recapture on track
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.
