One of our research cornerstones is sustainable biorefining. By addressing technical, economic and environmental aspects of our raw materials, technologies, processing routes and products, we seek to further improve our energy efficiency, reduce our water consumption and operate in ways that produce less CO2. This is our path to responsible biorefining:
Depletion and recyclability of fresh water
Scientists warn that climate change will have an especially big impact on the water cycle. That’s why Roquette considers innovative practices to continuously ability to strengthening water management vital to its future. To preserve this natural resource, the group seeks to adopt sustainable practices worldwide and to integrate its own and others’ sustainability achievements.
Roquette Amilina plant for liquid sugars in Lithuania was the first project of the Roquette Group which managed to substantially reduce both fresh water consumption and wastewater creation. It did so through recycling and reuse, actively working to minimize any adverse impact on the environment.
Thanks to its effective solutions, Roquette Amilina has kept consumption of fresh water low and reduced wastewater even as it’s increased wheat-refining capacity 1.4 times. The recycling of process water at the Roquette Amilina site is contributing to a reduction in fresh water consumption by the Roquette Group overall.
Note that, for historical reasons, Roquette Amilina site which began as a dry mill, has never needed its own wastewater treatment plant. Following Lithuania’s accession to the EU, municipal treatment plants in the area were fully renovated and modernized.
The company thus has a whole system in place for keeping water consumption and effluents low. In fact our numbers are currently among the lowest in the industry. But we continue pursuing further improvements, since the challenges of sustainability are never-ending.
How we achieved it?
– Municipal water replaced with condensate water, using unique technology to forward it to the process;
– Extraction of solubles from process water reduces effluent load to municipal waste water treatment plant;
– Condensate recovery for use as process water reduces fresh water consumption;
– Continuous ion- exchange system implemented in glucose plant.
