WELCOME TO STIMBR
EDN approval granted by EPA
The Environmental Protection Authority (EPA) has approved an application for a new gas to fumigate export logs and timber.
EDN (ethanedinitrile) is a fumigant gas that kills common pests found in wood. It is a potential alternative to methyl bromide, an ozone-depleting gas, the use of which is becoming increasingly heavily restricted. EDN offers a safer and environmentally sustainable fumigation treatment for timber imports and exports which are worth more than NZ$6 billion to the economy each year.
EDN is already approved for use in Australia, South Korea, Malaysia, and Russia.
EDN’s Czech-based manufacturer, Draslovka, applied to the EPA some years ago for approval to import the gas into New Zealand after completing efficacy and other scientific trials. These trials and other supporting activities have been a major investment and focus for STIMBR for several years.
The EPA’s approval does not mean that EDN can be used immediately. Approvals are required from the governments of importing countries, notably China and India, before treatment can start. Additional approvals are also required from WorkSafe NZ.
STIMBR (Stakeholders in Methyl Bromide Reduction Incorporated) brings together New Zealand industry, government and research organisations and individuals with the aim of:
Providing a united voice in support of initiatives aimed at enhancing market access and biosecurity clearances for goods and products while reducing the release of methyl bromide into the atmosphere.
The group provides an interface between users of methyl bromide, fumigators applying treatments, government departments concerned with reducing the use of ozone depleting substances, researchers seeking alternative treatments and strategies, and other affected parties.
New Zealand's Forest Exports Industry
Forestry is a vital component of New Zealand’s economy, contributing over $4.75 billion per year in export products. The majority of forest exports are required to meet strict phytosanitary requirements to gain market access to the importing country.
About Methyl Bromide
Methyl bromide is a highly effective fumigant gas that kills insects and other unwanted organisms. New Zealand timber products' exporters must use it to meet the biosecurity requirements of those countries importing their timber. Improperly used it’s a toxic gas that can adversely affect people’s health and the environment.
More detailed information about methyl bromide and its use in New Zealand as a phytosanitary fumigation treatment can be found here:
New Zealand and many other countries have signed up to the United Nation’s Vienna Convention for the Protection of the Ozone Layer and its accompanying Montreal Protocol that limit methyl bromide’s use. Methyl bromide contributes to damaging the planet’s protective ozone layer. The Montreal Protocol allows it to be used for quarantine and pre-shipment purposes, subject to demonstrable efforts to reduce emissions through containment and recovery.
Currently there are few viable alternative to methyl bromide for fumigation purposes. STIMBR in New Zealand is leading a significant research programme to find alternatives with a likelihood that there will be a number of solutions targeted to specific fumigation processes.
