Processing concepts for regulated animal
by-product streams

Public and private waste management companies may be responsible for collecting, handling, and processing animal by-products under strict regulatory frameworks. These materials require a technical concept that considers safety, logistics, treatment requirements, environmental systems, and long-term operational costs. We develop integrated solutions for companies managing animal by-product streams as part of a wider collection and processing system.

Designed around collection, treatment, and compliance requirements

Animal by-product management is not only a plant-level question. Collection routes, material variability, storage conditions, treatment requirements, site constraints, and final output routes all influence the right process design. A reliable solution starts with understanding the full material flow before defining the processing route, plant concept, utilities, odour control, effluent handling, and implementation scope.

From regulated material handling to usable outputs

For waste management companies, animal by-products can represent a logistical, technical, and regulatory challenge. With the right processing concept, these streams may be converted into high-value products or substrates for energy recovery.. The objective is to create a processing solution that fits the company’s collection model, regulatory context, material stream, and total cost of ownership 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 flow, collection model, and processing objective.

  • Type and category of animal by-product streams
  • Collection volume, variability, and logistics
  • Storage and handling conditions
  • Required treatment or pre-treatment route
  • Target outputs and approved use routes
  • Site conditions, utilities, and environmental requirements
  • Local regulatory framework and project constraints
02

Technology Study

A Technology Study provides the technical basis for evaluating feasibility, process route, and investment scope.

  • Raw material and collection flow assessment
  • Target output evaluation
  • Mass balance calculations
  • Process concept development
  • Site and layout constraints
  • Utility and environmental system requirements
  • Preliminary plant configuration
  • Yield, energy consumption, operational costs, and total cost of ownership (TCO) assumptions
03

System architecture and layout planning

The processing concept is developed as a connected system from intake to output handling.

  • Material intake and storage concept
  • Particle size reduction / pre-processing
  • Sterilization or thermal treatment requirements
  • Wet or dry rendering route evaluation
  • Fat, odour, and effluent handling
  • Automation, utilities, and control systems
  • Layout, logistics, and maintenance access planning
04

Implementation and support

WALDT supports the project from planning toward reliable industrial operation.

  • 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
  • Long-term technical assistance
