In Net Zero is good for business we wrote recently about what some leading Hawke’s Bay businesses – Napier Port, Silver Fern Farms and Hawke’s Bay Airport – were doing to curb their carbon footprints on the face of global warming.
And we invited other Hawke’s Bay companies and institutions to share their plans and accomplishments.
Tim Nowell-Usticke from WineWorks, the Hastings-based bottler for most of the wine industry, commented on our story:
“We at WineWorks have also committed to Carbon Zero a year ago, and this is in response to the whole wine industry recognising that sustainability is seen as a very important plank in our export customers’ buying decisions.
“So not only does it help us sell our product, but from our team’s perspective it is the right thing to do. We have started with a 30% net reduction per annum, which we are achieving, and a year ago we started investing in carbon credits here in NZ (native plantations) to offset to Carbon Zero.”
We asked Tim to elaborate on what WineWorks was doing to meet it 30% net reduction goal. His response:
“The first and most effective step towards not increasing our impact on global warming is to reduce what we send to landfill. Reduction of waste has a huge effect, especially in an industrial operation like ours.
“WineWorks has removed most of its rubbish bins – risky, you might think, but if the team are focussed on what we are trying to do, works really well, and this has been our single biggest improvement. Our number of 15m3 skips dumped has reduced from 65 to 18 over the last few years.
“Secondly, electricity is our single biggest contributor to our carbon footprint. We’ve been making inroads into the kWh per case by using automatic switching devices to turn off things that are not used – e.g., lights in a warehouse when nothing is moving, air compressors when no machines are running – and using variable speed drives that run machines as fast as they need to go rather than full speed all the time.
“Measuring things by how much power we are using per case of wine we bottle.
“We’ve still got plenty of changes to go. We’re looking at changing our gas usage from imported CO2 to Nitrogen that we make on site, heat recovery can be wasteful, and hot water production has potential to drive additional savings. I am confident we will be able to see another 10% in the next year or so.
“Then we start work on the big one, converting all electricity usage to fully renewable, replacing as much diesel as we can while we do that.”
All pragmatic moves – good for business, good for the environment.
Next time you open a bottle of wine, offer ‘Cheers’ to WineWorks!
