The Almond Board of Australia released the findings of its study in March, partly funded by the Australian Government, which examines ways to reduce the almond industry’s energy use by using almond waste products as fuel to generate energy. [ + ]

Around half of the primary energy consumed in industrial processes is currently wasted. Even steel produced by recycling scrap metal in electric-arc furnaces, for instance, requires approximately 370 kWh per metric tonne. In this type of furnace an electric arc is struck between several electrodes. The resulting heat causes the steel to melt before emitting a mixture of gases at up to 1700°C - a huge waste that might otherwise be used in the process or to generate electric power. [ + ]
