Animal by-product rendering solutions for
food processing facilities

Food industry manufacturers working with animal-origin raw materials often generate by-product streams that require dedicated handling, treatment, or further processing. These streams can compromise logistics, costs, product quality, environmental performance, and long-term plant efficiency. We develop integrated processing solutions that help companies manage these materials as part of a reliable industrial process.

Process equipment for food industry manufacturers handling by-products

Designed around production reality

By-product streams in food manufacturing can vary by raw material, production rhythm, composition, volume, moisture content, and intended output. A practical solution must reflect how the facility actually works. The right processing concept considers material intake, thermal treatment, separation, fat handling, odour control, effluent processing, utilities, automation, and available site conditions.

From by-product handling to value creation

Animal-origin by-products can represent a cost, a compliance challenge, or an underused material stream. With the right processing concept, they may be converted into high-value outputs such as protein meals, fats, liquid digest, feed-related ingredients, or substrates for further use. The objective is to create a process that fits the company’s material stream, target output, quality expectations, and total cost of ownership (TCO) goals.

How WALDT can help

WALDT is a specialized engineering and technology partner for animal by-product processing projects.
01

Assessment

The first step is to understand the material stream and the production environment

  • Type and volume of animal-origin by-products
  • Composition, moisture content, and variability
  • Production rhythm and handling requirements
  • Target outputs and quality expectations
  • Site conditions, logistics, and available utilities
  • Local regulatory and environmental requirements
02

Technology Study

A Technology Study provides a structured technical basis before major investment decisions are made.

  • Raw material and by-product stream assessment
  • Target output evaluation
  • Mass balance calculations
  • Process concept development
  • Site and layout constraints
  • Utilities and operating assumptions
  • Preliminary plant configuration
  • Total cost of ownership (TCO) considerations
03

Integrated solution design

The processing concept is developed as a connected industrial system.

  • Raw material intake and preparation
  • Particle size reduction / pre-processing
  • Sterilization or thermal treatment requirements
  • Wet or dry rendering route selection
  • Fat, odour, and effluent handling
  • Automation, utilities, and supporting systems
  • Layout and integration planning
04

Implementation and support

WALDT supports the project from planning to reliable operation.

  • Engineering support during project development
  • Installation supervision
  • Commissioning and start-up support
  • Operator training
  • Performance validation
  • Spare parts and maintenance support
  • Long-term technical assistance
