Breakthroughs in Hydrothermal Carbonization Unveiled at Polish Conference
Large-scale production of hydrochar from residual materials is becoming an established technology for the circular economy.
On July 5, 2024, Schwander Polska and TerraNova Energy hosted an influential event in Nowy Sacz, Poland, showcasing the latest advancements in hydrothermal carbonization (HTC). The gathering brought together international leaders from politics, science, and industry, eager to explore innovative solutions in CO2 removal and the local circular economy.
Pioneering Technologies and Applications
The highlight of the event was the TerraNova®ultra pilot plant, a cutting-edge facility demonstrating the potential of HTC to revolutionize waste management and climate protection. Attendees were introduced to novel applications of HTC, particularly in transforming organic residues—such as sewage sludge, municipal biowaste, and industrial by-products—into environmentally friendly Hydrochar with lignite properties. The obtained Hydrochar not only serves as a renewable energy source but also as an effective organic fertilizer, a promising alternative to imported mineral fertilizers.

Aligning with European Union Climate Goals
With the European Union's new legal framework emphasizing climate protection, sustainability, and resource recovery, local authorities and industries are under pressure to adopt innovative approaches. The HTC technology presented at the conference offers a viable solution, aligning with these stringent regulations. The process produces Hydrochar, a stable form of carbon that can be stored long-term, thereby sequestering CO2 and contributing to greenhouse gas reduction and therefor climate change mitigation.
Future Prospects and Market Potential
The market for CO2 removal is expanding rapidly, and HTC technology is poised to play a significant role due to its high efficiency and low cost. The potential for using Hydrochar in construction materials or for ground storage presents lucrative opportunities for obtaining CO2 certificates. Additionally, advanced technology for post-processing Hydrochar and treating HTC process water with membrane technology was also showcased, indicating a comprehensive approach to waste treatment and resource recovery.
