Having declared in July that all farm plastics sold in New Zealand will have to be recycled or reused, the Ministry for the Environment has made two major grants to help this policy become a reality.
Alice Rule, owner and winemaker at 3Sixty2 Wines believes we could all do better at completing the circular economy of glass; the best example of the circular economy in action
“Made from natural material glass is infinitely recyclable without losing quality, reduces the need for virgin materials as well as reducing emissions from the furnace,” she says.
With funding from the Glass Packaging Forum (GPF) and AGMARDT, Rule is researching the circularity of glass in the New Zealand wine industry and the unintended consequences a container return scheme could have to the New Zealand wine industry.
“New Zealand already has an effective recycling system in place for glass bottles and jars – one achieving a 62 percent recovery rate, and on track to exceed that. That’s an enviable statistic for any recyclable material, anywhere in the world.
“The system has seen significant investment by councils, recycling companies and the GPF. The GPF’s Government-accredited, voluntary product stewardship scheme funds grants which improve glass recycling in New Zealand.”
The GPF and Rule believe New Zealand’s glass recovery rate can be even higher, and the GPF is working towards a goal of an 82 percent recovery rate by 2024.
The break in the circularity of glass packaging in New Zealand is imported glass, the capacity constraints in the supply chain and the limitations created by customer demand.
“Imported glass not only has a far higher carbon footprint, but disrupts the circularity of glass recycling in New Zealand because those overseas glass producers are not part of the stewardship of that glass in New Zealand,” Rule says.
However, plans are afoot that could see a Container Return Scheme (CRS) brought in with Associate Minister for the Environment, Eugenie Sage, announcing in September that work is under way to design a Container Return Scheme (CRS) for beverage containers. Rule doesn’t believe that would significantly improve glass recovery rates.
“One possible outcome of the current consultation on the Proposed Priority Product and priority product stewardship scheme guidelines process is the implementation of a Container Return Scheme which would see a deposit of 20 cents per bottle.
“These additional levies will no doubt hurt a lot of producers, and it concerns me that the Minster of the Environment is interested in punishing an industry with a proven record and reputation for incentivising sustainable and environmental best practice.”
The CRS scheme will only be focused on glass beverage containers, not glass jars for sauces or other products.
That is one problem Rule sees with a CRS, plus the lack of circularity where producers keep resources in use as long as possible, extract maximum value and regenerate and recover materials at the end of the product’s life.
“Norway has arguably the best CRS scheme in the world with around 96 percent return rates- but is not circular because they don’t use this waste.
“I am not against the CRS, but it is only one avenue to increase glass recycling rates and they should not be a burden to the producer.”
The $1 million already given out to research CRS could have helped improve recycling efforts at regional levels, which would be far more effective, Rule says.
“The fastest way for government to get results would be to work with councils which have co-mingled recycling systems - where everything goes in one bin - to move away from this system to one where recyclables are sorted at kerbside.
“A good example is Tauranga City Council, which brought in a separate glass recycling system and just about doubled its glass recovery rate in a year.”
There are even larger repercussions she says, if New Zealand doesn’t take a proactive stance – and that is impact on our export markets.
“New Zealand Winegrowers need to be more proactive about our glass product stewardship, because our largest carbon footprint is our packaging and route to market- which is not yet being regulated in New Zealand and is in other countries. Solid waste (our packaging) is not yet being taxed or penalised, but we should expect that as an additional compliance in the coming years. It is inevitable that key export markets will want to see us comply with their waste minimisation legislation.”
