Pyrolysis is the thermal decomposition of organic materials at elevated temperatures in the absence of oxygen. It is a process that can be used to convert various feedstocks like biomass, plastics, and waste into valuable products such as biochar, bio-oil, and syngas. Brussels, Belgium, is a city that has been increasingly exploring the potential of pyrolysis technology to manage its waste and produce renewable energy. However, like any process, pyrolysis in Brussels may encounter troubleshooting issues that need to be addressed for optimal performance.
