Wastewater Reuse is a Sustainable Solution to Water Scarcity
UNICEF estimates that four billion people experience water scarcity for at least one month per year, and it is only getting worse as cities grow and climate change kicks in. But there is a solution right under our noses – literally. Wastewater recycling. Treating and reusing wastewater takes the pressure off limited freshwater supplies. The water can be used for farming, industry, ...

How Can We Prevent Sewage Pollution in the United Kingdom from Worsening?
There are 7.8 billion people on Earth, and the amount of human waste the population produces massively impacts the environment and human health. In sewers, human waste mingles with personal hygiene products, household chemicals, pharmaceuticals and other contaminants, creating highly toxic wastewater that pours pollutants and 6.2 million tons of nitrogen into coastal water every year. The result ...

What Is Virtual Water?
Even goods that contain no actual water can carry a great deal of virtual water “Virtual water” is a concept in use since the 1990s that assumes all of the water required to produce a good remains embedded within the good as it moves along the value chain. With the concept of virtual water, we can say a bowl of completely dry cereal contains all the water that was needed to grow and ...
