Within the framework of the International Bioenergy Congress, environmental technology expert Robert Lackner, from the company Thöni Industribetribe, presented revolutionary advances in the operation of biodigesters that promise to boost biogas production in a sustainable and efficient manner.
Lackner's intervention focused on the importance of agitation technology in the anaerobic digestion process, a key component in the generation of biogas from organic matter. His ideas and advances attracted the attention of those attending the congress.
Lackner is a representative of Thöni Industribetribe, a company based in Austria, and a collaborator in Spain with AguaSigma, a company specialized in water treatment based in Gijón. Thöni Industribetribe has 16 years of experience in the environmental sector and is dedicated to the installation of biogas plants around the world.
The main focus of Lackner's presentation was on the importance of proper agitation in biodigesters to ensure an efficient digestion process. He highlighted the need to provide bacteria with the necessary time to decompose organic matter and produce biogas, emphasizing the importance of maintaining optimal temperatures and adequate environmental conditions.
One of the key advances presented by Lackner was the agitator system developed by Thöni Industribetribe for more than 20 years. These agitators are characterized by their slow rotation speed, two to six revolutions per minute, and their paddles that keep particles in suspension instead of letting them settle to the bottom of the fermenter. This technology, with low energy consumption, guarantees an efficient process and minimal maintenance, allowing a substrate concentration of up to 15%.
Lackner supported his presentation with data and graphs demonstrating how Thöni Industribetribe agitators manage to keep 98 percent of the digester contents moving, even at low revolutions, significantly improving biogas production.
In a practical example, Lackner compared two digesters, one with a dry content of 10 percent and another with a dry content of 15 percent, demonstrating that the agitation system allows a 50 percent increase in biogas production and a reduction of investment and environmental footprint.
In summary, the agitation technology presented by Robert Lackner and Thöni Industribetribe promises greater efficiency in biogas production, with lower energy consumption, less maintenance and reduced environmental impact. This can have a significant impact on the bioenergy industry and sustainable waste management, especially in regions with limited water resources, such as Spain. The presentation concluded with an invitation to attendees to visit the company's facilities and ask additional questions about this innovative technology.
