Closed Loop
Tarac operates a closed loop system which has many facets:
Solid residuals
Grape marc, the skins and seeds left over from winery crush, are recycled by Tarac to extract grape alcohol via a steam distillation process. This process is undertaken at Tarac’s three strategically positioned production sites in key wine producing areas; Nuriootpa and Berri in South Australia, and Griffith in NSW.
Other solid winemaking residuals, such as filter cake, are also processed at Tarac. Calcium tartrate is extracted, from which Tartaric Acid is produced for use by the wine industry.
Liquid residuals
Liquid residuals, including distillation wine, tank lees, centrifuge waste and stripwater, are treated at Tarac’s joint venture waste water treatment plant in Nuriootpa, South Australia. The treated water is used to irrigate local vineyards and pasture, and to offset the consumption of mains water in Tarac’s own processes.
Energy
Tarac utilises Biogas, captured at its wastewater treatment plant, as a fuel in its internal production processes. This assists in the replacement of fossil fuels and reduction of greenhouse gas emissions.
Other Products
A range of products for different agriculturally based industries are produced at Tarac as part of its closed loop system.
The wine industry benefits from Tarac’s natural grape skin and seed tannins, the agricultural industry values stockfeed pellets and grape meal, and the horticultural industry uses TPR soil conditioner.
Services
Tarac provides a number of beneficial and cost effective services to the wine industry, these include AlcoTECH alcohol adjustment, permeate distillation and grape juice concentration.
