Recycling plants for commercial and mixed construction waste
From the feasibility study and pre-engineering to the turnkey plant. Waltec plans and implements robust, GewAbfV-compliant recycling plants that are designed for maximum efficiency and minimum downtime.
A strong partner for leading companies in the recycling and raw materials industry
Your investment in secure processes and high profitability
Holistic solutions for your added value
We specialize in the design and implementation of robust, highly efficient systems that precisely meet all legal requirements (GewAbfV).
New commercial and construction mixing plants
The design of turnkey new plants that are precisely tailored to the sorting requirements of the GewAbfV and your site conditions – planned for maximum quotas and profitability.
System expansions & retrofits
Does your site need to grow or meet new requirements? We plan and integrate expansions, conversions and modernizations seamlessly into your existing processes to increase your plant capacity and efficiency.
Modular sub-trades
Conveyor technology, hopper, dosing unit and steel construction – coordinated and easy to service. Integration into existing layouts and process chains without increasing complexity.
Feasibility studies
The solid basis for your investment. We analyze your location, the material flows and the legal framework and prepare a detailed study on the technical and economic feasibility of your project.
System concept & basic design
We develop technical layouts and holistic concepts that take into account all material flows, sorting targets and location factors and form the basis for tailor-made planning.
Pre-engineering
In this detailed planning phase (pre-engineering), our engineers develop the exact technical basis and budget for the final realization of your project.
Air & dedusting technology
Clean operation is essential. We integrate high-performance air and dust extraction systems (e.g. air separators, extraction systems) into our concepts in order to comply with emission specifications and ensure workplace quality.
Realization & commissioning
As part of the Heide Group, we control the entire process. Our sister company, Klamotec GmbH, manufactures the robust components and assembles them on schedule – for guaranteed quality from a single source.
Service, training & spare parts
A system is only as good as its service. We safeguard your investment in the long term – with maintenance, training for your operating personnel and a rapid supply of critical spare parts.
Planning and execution from a single source
As your general planner (Waltec), we manage the entire process from the feasibility study to acceptance. The decisive advantage lies in our group of companies: our engineering concepts seamlessly draw on the specialized expertise of our sister company, Klamotec GmbH.
You receive a system concept from Waltec that is designed from the outset for proven, robust and punctual implementation. We eliminate the risks and interface losses that arise between pure planning offices and external implementation companies.

Guaranteed conformity: your system concept in accordance with GewAbfV
We specialize in the planning and design of systems that precisely comply with all current directives and regulations of the German Commercial Waste Ordinance (GewAbfV).
Compliance with the Commercial Waste Ordinance is the decisive factor for the economic efficiency and sustainability of a recycling plant. Our engineers integrate compliance with all requirements into your concept right from the initial feasibility study.
Precise material flow analysis
Our concepts define and separate all material flows (material streams) exactly as required by the legal regulations for feeding them for sorting.
Achieving the sorting quotas
We plan the plant technology and the process chain specifically to achieve and maintain the prescribed sorting quotas.
Complete documentation
We provide audit-proof technical documentation of all processes and components that you need for official verification.
Guaranteed acceptance reliability
Our expertise in pre-engineering and our focus on compliance eliminate approval risks before they arise and ensure the final, trouble-free acceptance of your system.
Specialists for the most demanding sectors of the circular economy
Our engineering concepts are precisely tailored to operators and investors who need to process complex material flows in accordance with the highest legal and economic standards.
Building rubble & mineral waste
We plan and implement complete systems for processing construction waste and mixed construction waste. Our concepts are aimed at efficiently separating valuable raw materials (e.g. metals, wood) and purifying mineral fractions for recycling.
Commercial waste & sorting residues (GewAbfV)
Our absolute core competence. We specialize in the planning of sorting plants that meet all the requirements of the German Commercial Waste Ordinance (GewAbfV). The focus is on achieving the highest sorting rates and ensuring trouble-free production.
Plant operators & investors
Our partners are large, medium-sized and international recycling companies and investors who are looking for a robust, turnkey and profitable solution for a new site or plant expansion.

About us - Engineering excellence for the circular economy
Waltec combines in-depth process know-how in recycling with the implementation strength of an experienced manufacturer network. Waltec is not just a machine supplier.
We are a highly specialized engineering team and general planner for large-scale turnkey recycling plants. Our thinking is geared towards the goals of investors and operators: We design plants for construction waste and commercial waste that are designed for maximum efficiency and precise compliance with legal requirements (GewAbfV).
As a Heide Group company, we offer a decisive advantage over pure planning offices. Our engineers plan concepts that are already tailored to the proven, robust components of our group of companies.
For you, this means: no interface losses, guaranteed quality in execution and a system concept that is conceived and realized from a single source, from the first drawing to the last screw.
From the idea to a profitable investment
Our structured engineering process safeguards your investment at every stage and guarantees compliance with all legal requirements (GewAbfV).
Analysis & feasibility study
It all starts with your goal. Our engineers analyze your location, the planned material flows and the economic viability. In a detailed feasibility study, we assess the profitability and technical requirements of your project.
Concept & Pre-Engineering
Based on the analysis, we develop a customized system concept. We create initial technical layouts, define the core components and provide a sound budget as a transparent basis for your investment decision.
Detail engineering & compliance
This is where the detailed planning begins. Each component is technically designed and finalized in the CAD system. At the same time, a complete check for GewAbfV conformity is carried out to guarantee the subsequent approval and acceptance of your project.
Realization control
As your general planner, we manage the entire construction process. We coordinate the production of the robust components, manage all trades on the construction site and ensure adherence to the time and budget plan through active interface management.
Commissioning & long-term support
We do not hand over a construction site to you, but a turnkey, running system. After successful performance tests, we train your operating personnel and remain at your side as a reliable service partner for maintenance, training and spare parts.
