To solve the homogeneity challenge the Torrgas founders co-developed a scalable torrefaction process from 2006-2011. The torrefaction step converts heterogeneous, low quality biowaste streams into homogeneous, high energy density solid biofuels. By this energy densification also transport costs are significantly reduced. The torrefied product is the feedstock for the Torrgas gasification technology.
The Torrgas team broke with convention and took a fundamentally different approach than the rest of the industry. Rather than focusing on one step gasification of local available untreated feedstocks they developed the concept of a two step gasification process that has the following advantages:
- No slagging
- No tar formation
- Possibility for minerals recycling (biochar)
- Increased reliablity of operation
- Scalable to industrial sizes due to application of torrefied material
Between 2012 to 2020 the team developed the gasification technology towards TRL 8 and are continuously working on further optimalisation. Torrgas Technology BV is in the possession of trade marks, trade secrets and proprietary information and has filed numerous patents directed to this gasification technology and is in an exclusive position to license this technology.
