Integrated industrial solutions for animal by-product rendering

WALDT helps companies optimize animal by-product rendering, turning raw streams into defined, marketable outputs through engineering advisory, process design, and integrated industrial technology. We support each project from the first technical questions to implementation, commissioning, and long-term operational support.

What we do

WALDT supports animal by-product processing projects from early technical assessment to industrial implementation. Our role is to help define the right process, integrate the required technologies, and support reliable long-term operation.

We approach each project as a complete industrial system, where process definition, technology integration, and long-term operational reliability must work together.

Our projects are “Designed to last”

Designed to last is WALDT’s engineering principle: each solution is designed around real raw material characteristics, operating conditions, maintenance needs, and long-term investment goals. The aim is robust industrial performance, stable operation, and a service life that supports the client’s business case.

By-product rendering applications

We support animal livestock farms, slaughterhouses, rendering plants, meat processors, feed producers, pet food ingredient producers, and biofuel-related projects.

Start with a technical conversation

Whether you are planning a new rendering facility, expanding existing capacity, or reviewing an existing process, WALDT can help you clarify the technical route before major decisions are made. We look at your raw material stream, target outputs, site constraints, utilities, and operating goals to define what is feasible and what solution scope is required.

The people behind WALDT

Animal by-product processing projects depend on technical judgement, operating experience, and trust. WALDT brings together engineering and commercial execution backgrounds to support clients from early decision-making to full project delivery.

Mission & values

WALDT’s mission is to support animal by-product processing projects through engineering-led industrial solutions built for long operational lifetime and predictable performance. We do not approach projects as standalone equipment sales. Each assignment is developed as an integrated technical system, defined by raw material characteristics, target outputs, site conditions, available utilities, regulatory requirements, and total cost of ownership.

Our work is built around reliability, process efficiency, product quality, and practical operational support. From feasibility assessment and process concept development to engineering, equipment integration, commissioning, optimisation, and after-sales support, WALDT helps companies make well-founded investment decisions and implement solutions that fit real operating conditions.

WALDT aims to be more than an equipment supplier. We are a long-term engineering and solution partner throughout the full project lifecycle — from concept development to implementation, optimisation, and after-sales support.
