Agricultural biomass
Biomass
With the increasing shortages of fossil energy media, the use of biomass for generating energy is becoming increasingly important. For this reason, there is a worldwide increase in the number of installations which use fermentation processes to produce biogas from renewable resources, residues of animal husbandry and also from bio waste. Powerful GEA decanters process the fermentation residues efficiently and reliably. They not only make a vital contribution to environmentally sound energy production; they also help to make a significant contribution towards boosting the effectiveness of biogas installations.
Fermentation residues yield high-quality fertilizer
Fermentation residues that result from the fermentation of biomass represent a valuable fertilizer for modern agriculture. However, the residues need to be processed both to reduce the levels of nutrients and to produce a fertilizer that is transportable and marketable. GEA decanters are ideal for this task and offer numerous advantages.
Decanters ensure high degrees of separation for very dry solids
GEA decanters reliably separate the solid particles and dewater them to a dry, free-flowing consistency. Demonstrating high throughput capacity, the decanters can handle large volume flows, and guarantee a high dry matter content in the solids of up to 30 percent. And because the clear centrate water can be recycled back into the fermentation process, the use of fresh water is minimized, which further reduces operating and disposal costs.

Decanter Centrifuge
The decanter’s hour has come as soon as the solids content in the suspension to be processed is particularly high. These machines provide the benefits of high clarifying efficiency and maximum dewatering as well as the separation of liquids with the simultaneous removal of solids. The main requirements in this respect include a high bowl speed, a...
Jet pumps
Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids and for the production of vacuum in which a gaseous or liquid medium serves as the motive force.

GEA reports profitable growth for 2025 and expects accelerated revenue growth
GEA’s past fiscal year was one of significant growth and further profitability gains. In particular, the technology group substantially increased order intake, with all divisions contributing here. GEA also made progress in all Mission 30 strategic growth areas. In addition, GEA met key interim targets under its climate plan ahead of schedule. Major milestones in fiscal year 2025 were admission to the DAX index, the award of one of the largest contracts in the company’s history, and streamlining of the corporate structure.
How SmartParc is rewriting the rules of food production
Thanks to a new SmartParc manufacturing site, food processors in the U.K. are cutting their running costs and emissions. With GEA heating and cooling technology at its core, this collaborative production model demonstrates how innovation is accelerating the industry’s net-zero ambitions.
The food science playground
“Brewing eggs is like brewing beer.” It’s the kind of comparison that makes you smile – and then it clicks: Something complex suddenly feels simple. Through this personal film, set in the agricultural heartland of the U.S., we explore precision fermentation and the real-world work it takes to turn an idea into food.
