Since the establishment of Tyrrells Environmental Management program in September 2009, we have strived to minimize our energy usage by making ourselves far more energy efficient.
In the past 6 years of our EMS Program, we have reduced our Greenhouse Gas Emissions by a massive 65%, a total saving of 2,485 Tonnes less carbon dioxide (produced from coal-fired electricity).
Please read on to see some of the initiatives we have implemented to achieve this result.
In mid-2015 Tyrrells installed a 350kW Solar Power system, capable of producing enough electricity to halve our Greenhouse Gas Emissions from coal-fired electricity. In it’s first 12 months of operation, exactly one-third of our Total Electricity consumption was generated from Solar Power, which resulted in a saving of 575 Tonnes less Greenhouse Gas Emissions this year, compared to last.
Refrigeration is probably the biggest energy consuming sector of most Australian wineries.
Tyrrell’s runs a very economical refrigeration system by maintaining cooling water temperatures of between 6 and 8°C. (Many wineries run a refrigerated brine system to recirculate the cooling liquid at temperatures a few degrees below zero). Tyrrell’s system therefore uses far less energy.
On top of this, Tyrrells have installed 4 x Variable Speed Drive (VSD) pumps to recirculate our cooling water. These VSD pumps are far more efficient than normal pumps, with measured energy savings of 60% compared to the previous pumps.
We have upgraded our air conditioners and air cooling units in our warehouses and barrel sheds to run more efficiently. Units have either been replaced or upgraded with thermostats to ensure they are only ever running when absolutely necessary.
We have also spray-coated the main winery roof with Heat Reflective Paint, which greatly reduces temperatures within the building, thereby significantly reducing the load on our refrigeration plant.
Hi-Bay Lighting in our main winery building has been replaced with Low Energy Induction Lights, which use far less power and have a longer service life.
In September 2009 Tyrrell’s became one of the first wineries in Australia to start bottling with O-I Australia’s new environmentally friendly “Lean & Green” range of super-lightweight glass bottles. These bottles are 30 – 40% lighter in weight than the bottles they replaced, with around 150 grams less glass in every bottle, thus contributing to far less greenhouse gas emissions during their production and their transportation to and from our winery.
Approximately 75% of Tyrrell’s wines are produced in this lightweight bottle range, thus marking a significant contribution by Tyrrell’s towards reduction in carbon emissions.
Since the establishment of our EMS Committee in mid-2009, we have recorded a significant 55% reduction in our Total Fuel Usage over the past 6 years. This has been achieved through reduction of our petrol car fleet and switching over to diesel alternatives, as well as purchasing more fuel efficient vineyard vehicles and more efficient spray carts to reduce the no. of spray passes and therefore use far less fuel in the management of our vineyards.
