This issue goes beyond the technology to the practical challenges behind it: why feedstock quality makes or breaks gasification and liquefaction projects, why mechanical recycling alone cannot solve the plastic problem, and how automation and digital monitoring are quietly reshaping how alternative fuels are produced. You’ll also find our report from the Future Cement Initiative workshop at KAUST in Saudi Arabia, and an interview with Dirk Lechtenberg on the fast-changing RDF market and rising CO₂ prices, and a refreshing detour into SpoGomi proof that sustainability sometimes starts with people simply picking up trash. Enjoy the read, and perhaps a little optimism for where our industry is heading.
