How glassmakers can save energy and costs in the glass making process

Published 29th September, 2020 by Greg Morris

Glass factories are undergoing significant sustainability improvement especially in terms of energy efficiency. Nevertheless still today, 30-35% of the energy input in glass production is lost in the off-gas. This waste is an economic loss and it can be leveraged using proven technologies, such as Organic Rankine Cycle (ORC), to benefit both the glass producers and the environment. In the last 10 years Turboden, in the frame of environmental sustainability, has proposed and installed successfully several waste heat recovery systems, based on ORC technology, to recover the thermal power available in the waste gas at furnace’s outlet and valorize it producing electricity or compressed air.
