With the increasing availability of electrical energy from renewable sources, it will be possible in the future to drive many chemical processes using an electric current. This will facilitate the use of sustainable methods to manufacture products or fuels, replacing current processes which are based on fossil fuels.
Researchers have synthesized a biodegradable alternative to polyolefins using a new catalyst and the polyester polymer, and this breakthrough could eventually have a profound impact on sustainability efforts.
Capturing the greenhouse gas CO2 from industrial processes such as cement manufacture is a demanding and therefore expensive exercise. However, by introducing a renewable powered heat pump in the capture system, the energy required to capture CO2 is reduced by three quarters.
The mechanism depicted by the scientists will help in creating physically based combustion models required for the development of fundamentally new ecologically friendly combustion chambers for gas turbine engines.
For every 10,000 visitors frolicking in the waves, about 4 kilograms of mineral particles are washed into the beach water each day. These minerals catalyze the production of hydrogen peroxide, a well-known bleaching agent, at a concentration high enough to harm coastal marine organisms.
