Already Working Towards a Circular Economy - Examples in South Australia


The Sundrop System uses a combination of proven technologies to grow high-value crops using seawater and sunlight. The system allows Sundrop to produce more from less; growing pro ts while breaking farming's worsening dependency on freshwater, farmland and fossil fuels. The 20 hectares of greenhouses at Port Augusta will produce 15,000 tonnes of prime truss tomatoes worth tens of millions of dollars a year. The hydroponic operation is located on degraded land not usually considered suitable for agriculture, and is powered by more than 23,000 mirrors focusing the sun’s energy at the top of a 115m tower. The system saves around 16,000 tonnes CO2-eq, 450,000m3 of fresh water and has created more than 150 jobs in a new high tech industry.


Peats Soils & Garden Supplies

Peats Soils & Garden Supplies uses waste organic material to produce high quality compost products. They developed their own proprietary process to manufacture Blend 437, a nely-screened humus – the most stable and long-lasting form of organic matter. It has been eld demonstrated to improve crop yield and quality for viticulture, broad-acre and horticulture. Blend 437 has been further re-manufactured into PEATS TAILORMADE Prill, a more advanced product in owable form to allow easy application by farmers through air-seeder equipment during crop sowing. Peats is also upgrading one of their depots to extract additional value from waste organic material, through anaerobic digestion. This generates bioenergy to supply electricity to plant used at the depot, and manufacturing biodiesel to replace fossil fuel use in machinery and trucks.
