Making a net zero carbon economy

Food waste is one of the least recovered materials Click & Tweet! and is one of the most important materials to divert from landfills. Food that is disposed of in landfills decomposes to create methane, a gas that is 25 times more potent than carbon dioxide. Diverting even a portion of this waste to waste-to-energy systems could free up large amounts of landfill space as well as provide renewable energy for a variety of uses. Making a...

The Danish food-water nexus challenge

With the global population projected to reach 9 billion in 2050, demand for food is expected to increase by 70% in 2050. It is estimated that to meet this increased demand for food, global agricultural water consumption will increase by around 19% by 2050. However, agricultural production is one of the largest sources of non-point source pollution Click & Tweet! impacting the availability of good quality water for other users and uses...

Mitigating bio-energy-food nexus pressures

Countries around the world are beginning to transition away from fossil fuel-based economies towards bio-economies that use biological sources, materials and processes to achieve sustainable economic, social and environmental development. One of the main activities in a bio-economy is the production of bio-energy, which is energy produced from organic matter or biomass. The most common form of bio-energy is bio-fuels (combustible...

Demand management reducing energy-water nexus pressures

Nearly half of all water withdrawn in the U.S. is used to cool thermoelectric power plants, ensuring they operate safely and efficiently: On average a kilowatt-hour of electricity requires 25 gallons of water to be withdrawn from rivers and lakes. However, changes in precipitation, increased risk of drought, reduced snowpack and changes in the timing of snowmelt will impact the availability of water for electricity production. Reduced...
