Pillars of Sustainability
As with our other environmental key performance indicators (KPIs), the decrease in the volume of feedstock crushed in our assets worldwide in 2020 led to challenges in the reduction in our water consumption index. However, a significant reduction was still achieved through a combination of leakage control, water reuse and process improvements.
In our juice production facility in Bebedouro, Brazil, the water used to wash the dry peel was previously discarded as unusable due to its high sugar and nitrate content. A water filtration system had been installed, including an evaporator to concentrate the water, to recover and recycle this water for reuse. This allows us to reuse 25 to 30m³ of water every hour, which amounts to about 600m³ per day and more than 16,000m³ per month.
*It is measured in cubic meters per metric ton (m³/MT).
In Claypool, US, the water used in degumming – the process whereby gums and lecithin are removed from crude soybean – was previously discarded as sewage. A degumming condensate recovery system has been installed, and we are now sending the recovered water to the plant’s boiler. This has led to environmental benefits on several fronts: saving water, reducing water treatment, cutting natural gas consumption and avoiding heat loss.
In Dongguan, China, a major new wastewater recycling initiative has resulted in a 33% year-on-year reduction in water use.
