Dry rendering or wet rendering
Two routes, two profiles. Most plants are clear which one fits before they pick up the phone.
Dry rendering solutions
Dry rendering separates fat from animal by-products using as little water or steam as possible. Steam is confined within a jacket surrounding the vessel holding the material - giving you a high-capacity process with low operating costs.
Available for processing your meat, bone and offal inputs either in batches or as a continuous flow.
Wet rendering solutions
Wet rendering typically injects live steam directly into the vessel holding the material. You benefit from reduced steam consumption, lower operating costs and better quality in your meal and fat outputs.
Available in batch or continuous configurations.
Haarslev solutions for your meat, bone, fat, blood and bristle streams
Grouped the way a plant engineer thinks — by processing route first, then by the specific by-product stream.
Traitement en séchage discontinu
A straightforward, versatile way to treat all kinds of raw material from your operations.
Traitement en séchage continu
A reliable, high-capacity process that keeps your operating costs low.
Continuous low-temperature wet rendering
Reduced steam consumption, low operating costs and better-quality meal and fat.
Continuous pre-cooking & batch sterilisation
High evaporation capacity and Category 1/2 compliance, usually without needing to reduce particle size first.
Gel-bone production
Delivers high-quality tallow at a price premium, with meal that's low in fat and ash and highly digestible.
Processing blood
Coagulation, separation and drying into high-protein, high-lysine blood meal for monogastric and aqua feed.
Processing bristles & hair
Dewatering and hydrolysing pork hog hair into a valuable keratin-based feed ingredient instead of treating it as waste.
Dewatering using waste heat
More dewatering capacity for less energy, with reduced environmental impact — waste-heat evaporation recovers stick-water solids and lifts overall yield.

Manage the smells the neighbours notice
We provide effective systems for handling the smells and emissions that come with meat processing and rendering - thermal oxidisers, scrubbers, air washers and closed conveying. This matters for worker health and safety, community relations and regulatory compliance.

We supply industrial control systems and advanced digital tools — including CORE process control and Haarslev Connect monitoring — that get the best out of your rendering hardware, plus the well-structured data flows and documentation you need for efficiency and compliance.
Explore Haarslev control and monitoringSuperior odour control, from day one
When Prestage Foods of Iowa brought a major new pork operation online, odour management was the deciding factor — and the reason they chose Haarslev.
“We really saw Haarslev as sticking out with superior technology to control the odour.”
“This was a brand-new system to all of us. It's been very easy to train on - we've run it with people who've never done this before.”
Haarslev delivered a rendering line built around effective odour control and straightforward operation, turning trimmings and by-products into protein meal and fat for animal feed — with a team that was up and running fast, with no prior rendering experience.

- Plant operated successfully by staff with no prior rendering experience.
- Trimmings and by-products converted into protein meal and animal-feed fat from day one.
