Ford recycled over 65% wastewater
In 2000, Ford launched it’s Global Water Conservation Initiative. Global manufacturing facilities were ordered to decrease their water use.
The multinational succeeded. Since 2000, Ford saved more than 10.5 billion gallons of water – a 62.4% reduction.
Per vehicle, water use has decreased nearly 45 percent from 2000 to 2009.
Located in the Sonoran Desert in Mexico, the Hermosillo Stamping and Assembly Plant has limited access to water – a necessary resource for the manufacturing process. An extended drought and population increase has led to a strain on water supply.
The plant in Mexico installed a biological water treatment system, membrane biological reactor, which uses an ultra-filtration membrane process followed by reverse osmosis making 55 percent of the plants wastewater for reuse.
The treated water can also be used in irrigation, further raising the amount of recycled wastewater to 65%.
The Chennai Assembly Plant in India succeeded to decrease their water demand with 65% and recycles 100% of their wastewater into fresh water improving their impact on the surrounding communities.
Traditional industries decreasing footprint
We are already seeing companies look outside their own walls and work collaboratively to manage water resources with governments, local communities and civil societies. And we are seeing companies work at the river-basin level, with the aim of ensuring sustainable and equitable water use for all.
“The cost of inaction on water security is getting higher every year”
Head of water at global environmental reporting system CDP, Morgan Gillespy
According to CDP, there is a great opportunity to think about water as part of climate mitigation, with 24 per cent of business actions to reduce greenhouse gas emissions dependent on stable and secure supply. Encouragingly, it found 53 per cent of companies successfully reduced emissions via improvements to water management.
Joined-up thinking can drive change, concludes Gillespy. Understanding synergies between climate and water will be key to realizing opportunities and securing our low-carbon future.
