Robbie Davis's project to reduce food waste in agriculture saw her named 2016 South Australian Rural Woman of the Year. As chief executive of Potatoes South Australia, Davis was on a particular mission to save misshapen potatoes from ending up as cattle feed.

Every year, South Australian potato growers, in the biggest potato-producing region in Australia, rejecting thousands of tonnes of the unwanted tubers. A mindset had been created among consumers and growers by supermarkets that good potatoes had to have perfect skin, shape and size. This created “enormous waste”.

South Australian growers produce about 385,000 tonnes of potatoes annually but an estimated extra 20-40% went into stock feed or was dug back into the ground. That represented about $30 million wastage.

Potatoes South Australia has worked with the University of Adelaide on identifying technologies that could lead to more profitable alternatives. Treatments to extend the shelf life of potatoes is among possibilities. Another is pureed potato product suitable for infants and older people, with Australian hospitals and nursing homes are importing desiccated potato from Europe and New Zealand. A $10,000 bursary from 2016 SA Rural Woman of the Year awards sponsor Rural Industries Research and Development Corporation supported Davis’s research into other value-added options.

Davis has a bachelor of agricultural science and master of business administration from University of Adelaide, she is also a farmer near Meningie in South Australia's upper south east. Davis also has lived and worked in South East Asia where she gained significant experience in global markets before setting up her own agribusiness consultancy. She became a non-executive director of Fight Food Waste cooperative research centre started in 2018 at University of Adelaide’s Waite campus.

John Ridley's wheat reaper, The Stripper, saves early South Australian agriculture

John Ridley has been credited with saving the young colony of South Australia in the 1840s by inventing The Stripper wheat reaper. By 1843, the colony was in financial trouble but it had an expanding wheat crop – that would make South Australia the early granary of Australia – exceeding the workforce needed to harvest it by the old hand methods. Ridley produced a machine that enabled crops to be reaped mechanically. Combs and beaters swept off heads of wheat, so binding, carrying and stacking were avoided. Although Ridley won the prize offered by Agricultural and Horticultural Society for the invention, others believe that Mount Barker farmer John Wrathall Bull was first to come up with the idea, claimed as a world first. Arriving in South Australia in 1839, Ridley bought land to farm at Hindmarsh, near Adelaide city centre. He took over the South Australian Company flour mill and installed the colony’s first steam engine (a Watt’s beam) able to cut wood and grind meal. Ridley, a lay church preacher, refused to take out a patent, or received a reward, on his wheat reaper, allowing South Australia to reap the full benefits. Thousands of Ridley reapers were built. In gratitude, South Australian colonists presented a silver candelabrum to Ridley, who returned to England in 1853. The candelabrum is now at Waite Agricultural Research Institute. Ridley is honoured by a scholarship at Roseworthy Agricultural College, memorial gates and a pavilion at the Royal Agricultural and Horticultural Society's showground at Wayville and Adelaide suburbs Ridleyton and Ridley Grove.

Port Augusta centre boosts South Australia's fruit fly fight; state still vine phylloxera free

South Australia is the only Australian mainland state free of fruit fly, and one of the few places in the world free of the vine-destroying pest phylloxera. In a national first, BioSecurity SA researchers at a $3.8 million centre in Port Augusta develop 50 million male-only sterile Queensland fruit flies each week. Fruit fly management protects commercial fruit and vegetables, including wine grapes and almonds, with a farmgate value of about $851 million. It also secures important export markets.

August Fiebig violin maker who gave Kangaroo Island its special Ligurian bees

August Fiebig contributed musically to South Australia as a double bass player in 19th Century orchestras and as violin maker. But his claim to fame is as a bee keeper. A.E. Bonney, secretary of the South Australian Beekeepers Association, urged that Ligurian bees be imported and protected on Kangaroo Island. Whether Fiebig introduced the Ligurians isn't confirmed but he conserved the genetic heritage of the breed in his hives and sent the first batch to the island in 1887.

Sundrop Farms, world first with food from solar power, starts Port Augusta transition

Sundrop Farms, a $100 million plant next to Spencer Gulf, in 2016 led Port Augusta's transition from a coal-fired power station town to a solar industry region. Sunrop Farms, just south of Port Augusta, as the world’s first large concentrated solar power to provide multiple energy streams – heating, fresh water, electricity – for horticulture. Its greenhouse is in a warm-climate area lacking rainfall where traditional horticulture isn’t feasible. By applying its proprietary technologies, Sundrop Farms have been growing delicious, natural and high-quality produce, using Southern Ocean seawater and sunlight. Its water comes from the Spencer Gulf and is desalinated using a cutting edge thermal desalination plant. It uses a state-of-the-art solar tower to produce energy to desalinate the water, power the plant-growing systems and to heat and cool the greenhouses as required. topped by a 234-tonne central boiler, the 115m tower has 23,000 mirrors pointed at it. Sundrop secured a 10-year supply agreement with supermarket chain Coles that underpinned the Port Augusta project. Sundrop Farms can produce 17,000 tonnes of tomatoes each year using 22.5% less land than more traditional field production and uses significantly less water. Having moved its global headquarters from London to Adelaide in 2017, Sundrop is now looking to for opportunities to expand in Australia and abroad now that it has proved the decoupling of traditional greenhouse reliance on fossil fuels and freshwater reserves.

 

 

South Australia first in Australia to ban e-waste to landfill; Nystar plant to recover resources

South Australia was the first Australian state to ban electronic waste (e-waste) going to landfill. Whitegoods were banned from direct landfill disposal since 2011 and computers, televisions and fluorescent lighting from metropolitan Adelaide were banned from being disposed of directly to landfill in 2012. From 2013, those wastes and other e-waste are banned from direct landfill disposal across all of South Australia. E-waste comprises waste electrical or electronic equipment. Televisions, computers and their peripherals (mice, keyboards), whitegoods and fluorescent lighting are all e-waste. E-waste can contain hazardous materials including heavy metals and glass that, if broken or damaged, pose environmental hazards. Around 90% of what is used to make televisions and computers can be recycled. But e-waste has been liable to be landfilled interstate of exported to countries without environmental or health and safety rules. South Australia provided an important development for processing Australian e-waste, with the $514 million transformation of Nystar’s Port Pirie smelter in 2017 including a multi-metals  recovery plant. Nyrstar was expected to expand the range of e-waste for processing. A global multi-metals business, Nyrstar would accept electronics such as printed computer circuit boards, cathode ray tubes, phones and related devices. The expanded plant was expected to take photovoltaic cells from roof solar panels, alkaline batteries and other batteries such as lead acid and nickel cadmium. Treatment of e-waste was expected to increase to more than 20,000 tonnes a year.

South Australia ends bag handling of grain in 1950s with silos run by growers' cooperative

South Australian cereal growers, through their wheat and woolgrowers’ association, bought change to the way grain was transported and shipped from 1954. From the colony’s earliest days, moving grain from farm to the customer had been time consuming and expensive. Grain was collected in jute bags from the header and loaded onto a horse and cart, or train, to travel to one of South Australia’s 40 ports to be exported. A lot of grain was lost through spills, lack of hygiene and pest control. The South Australian Wheat and Woolgrowers’ Association lobbied hard for a bulk handling system and presented a proposal and draft bill to the state government in 1954. That year, the association formed South Australian Co-Operative Bulk Handling Limited (SACBH). The company bought its first silo in Ardrossan in 1955 and built the first country silo at Paskeville, on Yorke Peninsula, the next year. By the 1980s, SACBH’s storage capacity was more than four million tonnes. In the late 1990s, the Australian Wheat Board and the Australian Barley Board were privatised. South Australian growers approved a changed SACBH corporate structure in 2000 and it was demutualised as AusBulk and United Grower Holdings. Four years later, they merged with ABB Grain Ltd to form one of Australia’s largest barley marketers. In 2009, most shareholders voted to sell ABB Grain Ltd to Canadian global agribusiness Viterra who took over most South Australia’s silos and gave its grain exposure to different world markets. In 2012, Viterra was bought by Glencore Agriculture, a global leader in agricultural commodities.
