Blum Sustainability Report 2022

45 Change in water usage Our water consumption is determined mainly by the base load of the infrastruc - ture. The decline in WIJA 2020/21 may have also been influenced by the poor summer weather, which was unusually cold. Another factor is the reduction in sanitar y wastewater due to lockdowns, shor ter working hours and employees working from home. With the resumption of normal operations post -pandemic, the water usage has increased again. Over view of the use of recycled materials 301–2, 301–3 For us, the most effective way to conser ve resources is to use recycled materials. This applies to both our products and packaging materials. Steel : the king of recyclables 301–2 By far the most used raw material at Blum is strip steel. Steel can be completely reprocessed without any loss of qualit y – and as of ten as you like. That is why steel is also the most recycled material in the world, and a great option for saving on raw materials and energy.
