The new filter is made of Polylactic Acid and Bismuth Ferrite uses piezo-photocatalysis, which combines the principles of piezocatalysis and photocatalysis to enhance the degradation of pollutants and other chemical transformations. 

Researchers create a cleaner and greener bio-based proton exchange membrane for fuel cells made of plant and animal materials.

The problem of waste management is ubiquitous. With growing cities and exploding populations, the amount of waste that today’s cities generate is at unprecedented levels. Since most of urban waste ends up in open landfills, there is a need to relook and contemplate on better, greener ways of handling waste.
