Challenges
in animal processing

The field of animal processing is very diverse. It starts with the keeping of animals in stables or enclosures. The animals and their food produce species-specific smells during storage. Animal excrement and urine and their further processing are among the most common and strongest odor emissions. After that, slaughterhouses are one of the critical sources of bad smells. Here too, the accumulation of excrement and urine is an important factor, but in addition there is usually the utilization of the residual materials, which are thermally processed into protein and fat (rendering). Very unpleasant smells arise here due to the process.

Our solution approach

Depending on the origin of the exhaust air, different types of exhaust air purification systems can be used. These include scrubbers, biofilters and activated carbon filters. A combination of technologies is also possible. Which system is used here depends on the conditions on site (space, desired cleaning performance) as well as the origin and type of exhaust air (stables, manure and urine storage, rendering). We would be happy to advise you!

We provide you with expert advice and support throughout the entire project. From checking the functionality and assessing the overall system to regular maintenance – we ensure that your system always runs optimally.

Icon High operational reliability and long service life of the system
High operational reliability and long service life of the system

We manufacture our products from GRP. Glass fibre reinforced plastics (GRP) are made from reinforcing materials (glass fibre mats, fabrics, etc.) that are impregnated with various resins and chemical additives. This has many advantages: low weight with high resistance, non-porous and easy-to-clean surfaces, good thermal insulation values and low thermal expansion.

Icon High savings in energy and operating resources
High savings in energy and operating resources

The optimisation of production processes, the use of energy-efficient machines and systems and the implementation of intelligent control and monitoring systems can significantly reduce energy costs. The economical use of resources such as water, raw materials and packaging materials also helps to conserve resources and reduce environmental pollution. We attach great importance to this, both in our own production and in the planning of your systems.

    Meat processing in Liechtenstein

    Odor removal with biofilter

    The odorous exhaust air (2,000 m³/h) from the wastewater pretreatment process at a meat processing plant is cleaned in a biofilter with a pre-scrubber. The exhaust air is extracted from the various exhaust air sources via an exhaust air line.

    Multi-stage system in carcass processing

    At a carcass processing company in Germany, around 88,655 m³/h of odorous exhaust air is extracted and cleaned from the hydrolysis and production hall and from the raw materials hall. At the same time, another 80,000 m³/h of separate exhaust air is extracted and cleaned. The source exhaust air is pre-cleaned using a small counter-current scrubber. The collected exhaust air then goes into several biofilters via a three-stage cross-current scrubber.

    Cross-flow scrubbers and biofilters in carcass processing

    The odorous air from the processes (30,000 m³/h) and buildings (130,000 m³/h) of a carcass disposal plant is cleaned by a three-stage chemical cross-flow scrubber and a biofilter with an integrated pre-scrubber. The three-stage cross-flow scrubber is positioned in front of the biofilter and only pre-cleans the odorous air from the processes, while the biofilter post-cleans all the exhaust air.
