Des Moines, Iowa Patent of the Year – 2024/2025
Bristola LLC has been awarded the 2024/2025 Patent of the Year for its innovation in automated waste removal from anaerobic digesters. Their invention, detailed in U.S. Patent No. 11883863, titled ‘Auger cleaned inaccessible floor system’, introduces an auger-based cleaning system that operates without halting facility operations.
This system features a specialized auger cleaner that enters the digester through a controlled gate complex. Once inside, the auger agitates and transports waste through a connected pipe system, efficiently removing sludge without manual intervention. The design includes a boom and waste discharge pipe, ensuring continuous operation and minimal downtime.
The real-world impact is substantial. Facilities can maintain optimal performance without the risks associated with manual cleaning. By automating the waste removal process, Bristola’s system enhances safety, reduces operational interruptions, and supports sustainable energy production.
Founded in 2019 and headquartered in Des Moines, Iowa, Bristola specializes in renewable energy technology services. Their commitment to innovation is evident in this patented system, which addresses critical challenges in the maintenance of anaerobic digesters. By eliminating the need for human entry and allowing for continuous operation, Bristola sets a new standard in facility maintenance and safety.
