New low-cost, sustainable material for reducing air and water pollution

22-Mar-2018

A new class of low-cost and sustainable hybrid materials could possibly displace activated carbon as the preferred choice for reducing wastewater and air pollution. The material is synthesized inexpensively from solid wastes and a naturally abundant polymer -- and can cut down pollutants in air ...

Producing hydrogen from wet biomass

FAU researchers co-ordinate EU research project for improving sustainability in energy production

13-Feb-2013

Renewable energy sources – such as hydrogen from wind power – are an important step towards reducing greenhouse gases and protecting our climate. Hydrogen can be produced sustainably using other sources than just wind power: the European research project SusFuelCat aims to improve the process of ...
