A green method for obtaining vanillin from technical lignin produced from pulp

27-Feb-2023

Huge amounts of technical or Kraft lignin are formed during pulp production. This lignin is difficult to process and so is usually just incinerated for heat production. A team of researchers, reporting in the journal Angewandte Chemie, have now succeeded in developing a green method for ...

Chemists develop a method for producing cement by milling instead of burning lime, which is harmful to the environment

10-Nov-2021

Global warming and affordable housing are two dominant topics of public debate. Climate protection is achieved by reducing emissions of the greenhouse gas carbon dioxide (CO₂). Housing is generated through more housing being built. This requires concrete, the most important building material in ...
