Chemical Recycling

Mixing Technology for Plastic Recycling

Solvolysis and pyrolysis are two established technologies for chemical recycling. Both of these technologies involve demanding tasks for the mixing technology. This article summarizes the practical approaches to address these challenges — from lab, through piloting and demonstration scale, before building a commercial reactor or plant system.

Hydrogen Electrolysis

Eagerly Awaited: Hydrogen Electrolysis Comes of Age

Turning electricity into gas: a closer look at the key technology of the hydrogen revolution. Whether alkaline, PEM or high-temperature electrolysis, the oldest electrochemical process is to make the world of tomorrow possible. By 2021, projects with over 200 gigawatts of electrolysis capacity will be on the agenda. But what is behind these figures? What technologies are there, and where is the journey heading now?
