FAQ

Can M-GROUP also help with kilns that are not from Eberhardt?

Of course Regardless of the manufacturer or year of construction, we take on almost all technical planning, construction, project management and installation as well as ongoing support for your systems.

Is it worth retrofitting older lime plants instead of building a new one?

In many cases, yes. A retrofit can be an economically and technically viable solution to modernize existing lime plants, optimize processes and significantly extend the life of the plant.

Do you support a lime project from planning to installation and commissioning?

Yes With our various services, we support you throughout all project phases — from initial technical planning through engineering, construction and project management to assembly, commissioning and further support.
