Side Stream Valorization

Bühler helps you convert side streams and by-products from food, feed, and industrial processes into valuable ingredients and materials. Using biotechnology, separation, and process engineering, we design solutions that transform what was once waste into nutrients, functional ingredients, or bio-based raw materials – supporting both new revenue streams and sustainability goals.

From first opportunity assessment to full-scale lines, we develop tailored bioprocess concepts, integrate them into your existing plant footprint, and ensure hygienic, safe, and energy-efficient operation.

Explore our deep side stream expertise

Side Stream Valorization for your plant

We identify and qualify valorization opportunities in your processes, design suitable fermentation or enzymatic conversion routes, and engineer integrated lines from reception and pre-treatment to fermentation, separation, and drying. Together we build circular solutions that fit your existing operations and markets.

Opportunities & concepts

How Bühler adds value

We start by mapping your side streams and understanding their composition, variability, and current handling. Based on this, we identify promising valorization routes – for example fermentation, enzymatic conversion, or extraction – and develop bioprocess concepts tailored to your streams, utilities, and existing footprint.


What you get

  • Assessment of valorization opportunities in your process
  • Concept flowsheets for fermentation / enzymatic / extraction routes
  • Indicative volume and value potential for each concept
Products & markets

How Bühler adds value

We connect specific side streams to concrete product opportunities in food, feed, and industrial markets. Examples include cereal, oilseed, and starch side streams for food and feed ingredients; functional components such as post-biotics or texturizing agents; and industrial materials such as bio-based monomers, polymers, or platform chemicals.


What you get

  • Mapping of your streams to food & feed, functional ingredient, and industrial applications
  • Example product concepts and target specifications
  • Guidance on quality, safety, and regulatory considerations
Sustainability & environmental impact (incl. LCA)

How Bühler adds value

Side stream valorization is a powerful lever for circularity and footprint reduction. Together with Bühler’s Environmental Impact Services, we can complement your project with Life Cycle Assessment (LCA) to quantify CO₂ footprint, energy and water use, and other key indicators. This shows how valorization concepts compare to current disposal routes and supports your sustainability reporting and brand story.


What you get

  • Qualitative and quantitative view on waste, emissions, and resource savings
  • Optional LCA from Bühler’s Environmental Impact Services for selected concepts
  • Clear sustainability metrics to support internal targets and customer communication

We identify and qualify valorization opportunities in your processes, design suitable fermentation or enzymatic conversion routes, and engineer integrated lines from reception and pre-treatment to fermentation, separation, and drying.
