complete, the watery waste left over then goes through anaerobic digestion where the microbes break down the waste into methane and carbon dioxide biogas. This biogas can be used for heat and electricity. It is also possible to use fats, oils, grease, and meat products for rendering and biodiesel production. Composting Add remaining food waste to an existing compost. Composting has many benefits over general waste landfills, including reduced methane gas production and improving the quality of the soil. Countries Organizations in communities around the world, and national and international agencies, are concerned with rescuing food, minimizing food waster, and preventing the release of greenhouse gases from decomposing wastes. The 2015 Sustainable Development Goals (SDGs) call for a 50% reduction of global food waste at the retail and consumer levels worldwide by 2030. Australia an estimated one in six Australians experiences food insecurity. Australia was the first country to adopt the Sustainable Development Goal of a 50% reduction in food waste, with the Australian government providing some support for food rescue initiatives. Australia’s leading food rescue organization is OzHarvest. OzHarvest works with over 3,000 food donors and 1,800 charities in Australia and has provided over 210 million meals. Locations can be found using its online resource locator. OzHarvest was launched in November 2004 by Ronni Kahn. As an event manager in the hospitality industry, Kahn had first-hand experience of the amounts of food being wasted at events. In addition to founding and directing OzHarvest, Kahn organized lobbying of the Australian government. In July 2005, Australia's Civil Liability Act was changed to enable OzHarvest and other organizations to repurpose food for charitable purposes without risk of liability. Canada Food Banks Canada is a national charitable organization for food banks across Canada. In 2017, one in eight families (12.5%) in Canada were reported to be short of food. As of June 2022, Food Banks Canada researchers found that one in five Canadians (20%) reported going hungry. University students in Canada are a particularly high risk group for food insecurity. Meal Exchange, a Canadian charity, surveyed students at 13 Canadian universities. They reported that 56.8% of the 6,167 students surveyed in October 2021 experienced food insecurity, compared to 41.7% of respondents in 2020. Indigenous, LGBTQ+ and international students were even more likely to be in need of food. Second Harvest Toronto was started in Toronto, Canada in 1985 by Ina Andre and Joan
