Green thread Plant modernisation
Success with future-proof and sustainable strategiesAndernach 9 Sept 2024 - The idea of sustainability characterised many aspects of a major project at Ehl-AG. The Wittenburg plant is the company's most modern site today after extensive modernisation measures. In addition to Masa, Ehl brought other well-known project partners on board for the planning and realisation.
Ehl‘s corporate colour is “Green” – a colour that is not exclusive to the company‘s corporate design. Green is also the commitment to sustainable development. For example, Ehl relies on production with energy-saving machines, responsible use of resources and continuous optimisation of recipes. Or on sustainable modernisation strategies, such as at the Wittenburg plant.
The overall success of this site results from the sum of many individual factors, including the plant design and machine technology. Taken individually, these two aspects offer plenty of scope for sustainability.
Focus I: The plant design
The guiding principle of „sustainability“ had a decisive influence on the basic design of the new facility. On the one hand, the existing hall in Wittenburg was only to be extended as far as necessary. On the other hand – with a view to possible future market development – ways were to be left open for further investments, for example in the silo system or the dry side. At the same time, Ehl expected a plant orientated towards the demanding CRH safety concept, which would offer the opportunity to reinvent products.
The plant concept, which took into account both the conditions on site (construction in existing buildings) and the aspects of diversity, efficiency and safety of the new plant, covered several points:
- Successful integration and expansion of existing areas
- Measures on the way to the zero-waste concept
- Realisation of a customised security concept
- Delivery of a plant with optimised energy efficiency
The Masa QA system with Offset inspection station is just one of the well thought-out components in the Masa safety concept.
Focus II: Machine technology
Product variety, flexibility, quality and quantity – compared to the previous production plant in Wittenburg, the new plant should be a real quantum leap for Ehl, especially in these areas. The essential levers were, among others:
- Efficient technology and control for the mixing area (realised by Teka and Sauter)
- Exclusivity of the products through the use of the Masa Multi Colour System
- Masa Production Machine tailored to the requirements of gardening and landscaping and large-format products
- Uniform curing of the products in the Rotho climate chamber
- Flexible handling area with good accessibility (realised by Masa, with Rotho board buffer)

It's a long way from raw materials through the mixture to the finished stone. Many plant components are involved in this process. Only if the system components are matched, can one be assured of a smooth process and economical operation of the block and paver making plant.
The manufacturing of autoclaved aerated concrete products demands high standards for mixing and dosing of the aggregates, the control of the fermentation process and the control of each production step. Masa's aerated concrete installations are proven advanced technology processes, designed according to customers specific requirements. This approach allows complete solutions to ensure highly efficient, optimised processes resulting in consistent final product quality.
It's a long way from raw materials through the mixture to the finished sand lime bricks. Many plant components are involved in this process. Only if the system components are matched, can one be assured of a smooth process and economical operation of the sand lime brick production plant.
It's a long way from raw materials over mixture to the finished (Kerb)stone. Masa Kerbstone presses were developed to fulfill among other criteria, the special requirements of the "British Standard" kerbstones. This "British Standard" is still a condition in countries of the Middle East and the UK.
Masa plants and machines are installed and commissioned by our own experienced fitters. Masa relies on qualified personnel, trained in Germany.
The Masa Lifetime service extends far beyond the actual assembly and commissioning of a plant. Masa can rely on specific know-how and an industry experience of more than 110 years.
Do you need support with your machine? Masa Support scores in both quality and significantly improved accessibility.
