Taking care of tomorrow
Precision engineering that turns by-products into value
Meat, poultry and fish processors generate huge volumes of by-products, co-products and offcuts – every single day. Left alone, these become waste – a cost item bound for landfill or incineration. Handled well, these become revenue-generating proteins, minerals, fats, oils, feed ingredients and biofuels – commercially valuable materials in demand all over the world.
Haarslev designs, manufactures, installs, configures and services the equipment that makes such value-building transformations happen – from individual specialist machinery to complete, intelligently integrated processing facilities. Behind all the hardware lies decades of engineering experience, advanced control software and a customer-focused service network that keeps your operation running at its best.
The result: more value from every input, using less energy, with fewer environmental impacts.

We engineer better business
Haarslev has its roots in sustainable thinking – long before this key idea went mainstream. We enable customers to turn low-value residuals into higher-value products and ingredients, combining commercial gain with big reductions in environmental impacts.
That’s the heart of the circular economy: recovering, recycling and upcycling resources that would otherwise be discarded. By giving operations the means to do this efficiently and responsibly, we help companies meet their corporate responsibility commitments, sustainability goals, and ESG reporting obligations – and play their part in a lower-carbon future.
Origins in sustainable thinking — long before the idea became mainstream.
Perspectives are changing
The bigger picture around rendering and related processing is shifting fast. Societal expectations, legislative frameworks and corporate responsibility agendas are all changing drastically. Operations that don’t adapt to these changes risk being seen as part of the problem – instead of part of the solution.
As the recognised market leader in this specialist field, we lead from the front – by identifying effective solutions. We work with you and your teams to tackle changing circumstances and build future-facing opportunities, drawing on key capabilities that include:
Energy-efficient mechanical configurations
Forward-looking digital control and automation
System-wide circularity and responsible resource use
ESG-compliant documentation and data reporting
Results count
Rendering hardware is only as good as the results you get from it. Haarslev brings together hardware, control systems, processing know-how, streamlining capabilities and technical support as and when you need it – all tightly integrated so your operation actually performs the way you want.
Haarslev control and automation capabilities – the brains behind the engineering and hardware – get the most out of virtually any setup, regardless of manufacturer or configuration. They help you:
Streamline your operations
Roll back operating costs
Improve processing efficiency and output quality
Reduce environmental impact
And because we draw on structured operating data from Haarslev installations across the world, we help you keep optimising — so your plant adapts as conditions and requirements change.
Built for long-term value
Choosing processing equipment is rarely just about the upfront CAPEX price. What really matters is what your whole setup costs to run – and the long-term value it delivers.
That’s why Haarslev focuses on the total cost of ownership, the return you get on your company’s investment, and how you can document the impacts of your operations. Haarslev solutions are designed to maximise uptime, cut energy consumption and reduce maintenance – while our control and automation systems give you the flexibility to respond when input specifications shift and margins get tight.
TCO – total cost of ownership
ROI – return on investment
ESG / SBTi – sustainability metrics
The payoffs usually extend well beyond waste reduction. Nowadays, it’s measurable progress on key metrics that define a responsible, competitive business.
