Tarac's Closed Loop Technology has 3 facets:

Tarac can quickly identify the best quality marc to extract both grape skin and seed extracts. Marc not suitable for extraction is processed for calcium tartrate and grape alcohol recovery.

2. Solid by-products

The by-products from Tarac's processes are then used in a number of different markets. Solid residuals, or 'spent marc' is used for composting and stock feed. Spent marc is also being considered for a renewable energy source.

3. Liquid by-products

Liquid by-products are treated through a joint venture arrangement between Tarac and a major local winery. This facility is considered to be one of the most efficient and effective waste water treatment plants in Australia. Research is on-going in the use of treated water to irrigate vineyards and pastures whilst commercial supply agreements have commenced.
