Creating and producing carboxylic acids from waste


Introducing CAP-Technology by DRANCO: Revolutionizing Volatile Fatty Acid Production

Are you searching for a game-changing solution to convert organic waste streams into valuable resources? With a focus on producing volatile fatty acids (VFAs), including the highly sought-after Caproic Acid (C6), our groundbreaking Carboxylic Acid Production (CAP) – process sets a new standard in organic waste valorisation.

What sets CAP-Technology apart?
  1. Chain Elongation and Beyond: CAP-Technology stands out from other VFA fermentation processes by promoting chain elongation, resulting in longer VFA chains. Our process capitalizes on this unique feature, with a specific emphasis on Caproic Acid (C6) production. The extended chain lengths unlock a myriad of applications, including biofuels, biopolymers, and specialty chemicals, revolutionizing the potential of your organic waste streams.
  2. Proven Success through Extensive Research: DRANCO nv has developed CAP-Technology through extensive research and development, supported by multiple European and Flemish funded projects. Our dedicated team of experts has fine-tuned the process, ensuring optimal performance and scalability. Pilot-scale testing on both solid and liquid organic streams has yielded excellent results, paving the way for commercial implementation.
  3. Versatility and Integration: CAP-Technology offers flexibility in its application. It can function as a stand-alone process or be seamlessly integrated with DRANCO’s existing anaerobic digestion technology for biogas production from organic waste. This integration provides a synergistic approach, allowing you to maximize the potential of your organic waste streams by simultaneously generating biogas and producing VFAs through CAP-Technology.
  4. Sustainable Valorisation of Organic Waste: By implementing CAP-Technology, you embark on a sustainable journey toward the valorisation of organic waste. Instead of viewing waste as a burden, our process transforms it into a valuable resource, reducing environmental impact and promoting a circular economy. CAP-Technology empowers you to derive maximum value from your organic waste streams, contributing to a greener and more sustainable future.

Within the CAP-group, the focus lies mainly on research & development for alternative waste processing technologies. In the past, DRANCO nv completed many projects, including the VOLATILE project. DRANCO nv is currently partner in two European projects (RUSTICA, CAFIPLA) and one Flemish project (MEKKER) where it fulfills the responsibility of a technical partner as well as technical project manager. In these projects, DRANCO tries to build a new value chain around the CAP technology. DRANCO nv wants to further integrate the CAP technology with the installment of demonstration plants.
