Rendering plants

Integrated solutions for rendering facilities

Rendering plants need reliable processing systems that can handle variable animal by-product streams and turn them into high-value end-products such as protein meals and fats. WALDT develops integrated solutions for independent rendering facilities, capacity expansion projects, modernisation, and long-term plant performance.

Built around raw material, output, and operation

Every rendering facility depends on the balance between raw material quality, process route, energy consumption, product specifications, utilities, odour control, and site conditions. A strong rendering concept starts with understanding these parameters before defining the process, layout, technology integration, and investment scope.

Support for new plants, upgrades, and retrofits

Rendering plants may require a complete new facility, additional processing capacity, or improvements to an existing line. Each case needs a technical approach based on the actual plant environment. WALDT supports projects focused on yield, energy efficiency, product quality, operating stability, and total cost of ownership.

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 plant, the material stream, and the commercial objective.

  • Raw material type, volume, and variability
  • Target outputs and product specifications
  • Existing plant setup or new site conditions
  • Utilities, logistics, and layout constraints
  • Capacity expansion or modernisation goals
  • Local regulatory and environmental requirements
02

Technology Study

A Technology Study provides the technical basis for defining the right rendering concept.

  • Raw material and target output assessment
  • Mass balance calculations
  • Process optimisation modelling
  • Wet or dry rendering route evaluation
  • Site and layout constraints
  • Utility requirements
  • Preliminary plant configuration
  • Yield, energy consumption, product quality, and total cost of ownership (TCO) assumptions
03

System architecture and layout planning

The rendering plant concept is developed as one connected industrial system.

  • Raw material intake and preparation
  • Wet or dry rendering process integration
  • Sterilization or thermal treatment requirements
  • Fat handling and product management
  • Odour control and environmental systems
  • Effluent processing
  • Automation, utilities, and control systems
  • Layout and maintenance access planning
04

Implementation and support

WALDT supports the project beyond design and planning.

  • Engineering support during project development
  • Procurement and integration support
  • Installation supervision
  • Commissioning and start-up support
  • Operator and maintenance training
  • Performance validation
  • Spare parts and preventive maintenance support
  • Upgrades, retrofits, and long-term technical assistance
