ANDRITZ MeWa has developed its own technology for optimum preparation of packaged food, organic waste, and energy crops for the fermentation process in biogas plants. The Bio-QZ breaks down the cell structure of the substrates, thus offering the bacterial strains considerably more contact surface. Thus, gas formation starts measurably faster and intenser. This can reduce the duration of the overall process substantially and increase the cost-effectiveness of the biogas plants by over 30%. The new Bio-QZ generation is now available in a modern, compact, and also stable design in sizes 900 mm, 1200 mm, and 1600 mm.
