Basements built since 1980



is now part of the Glatthaar Keller Corporate

Michael Gruben, Marketing Director at Glatthaar Keller Germany: “For years we have been working hard adjusting our sustainable corporate policy. This includes investments in processes, production methods and administration, but there have also been smaller measures which at first glance have nothing to do with the actual production of our prefabricated basements. On closer inspection, however, it becomes clear that many cogs in the wheel must function together in order to be able to meet high environmental standards. In a survey, our customers have recognised our commitment, which shows that our measures are having an impact. "

Glatthaar Keller’s environmental improvements are both impressive and diverse. In 2019 and 2020 alone, over 1,800 tons of CO2 from transport were offset by climate protection projects. For every litre of fuel consumed, a contribution is made to a certified climate protection project run by the climate protection organisation “my climate Germany”.

When it comes to mobility, Glatthaar Keller is now relying on environmentally friendly transport with more and more electric vehicles in its fleet. 13 are already in use and the aim is to transition every vehicle to electric. The associated charging stations are about to be completed at all Glatthaar German locations. A home charging station will also be installed for employees with company vehicles. Last year Glatthaar Keller introduced bicycle leasing (which includes e-bikes) for all employees as part of the Employee Health Management scheme. Since then, 36 employees have taken up the offer and seven more will switch to this environmentally friendly means of transport in the coming weeks.


We aim to reduce the resources needed for our manufacturing process as part of our commitment to sustainability improvements. We are moving to a closed loop manufacturing process. Our modern production facility eliminates waste in all work areas. Optimising logistical processes and the associated use of energy is a key element of our corporate strategy. As part of our water management, we feed the recycled wash water from the concrete mixing plant into our production cycle thus eliminating wastewater. The heat needed for our concrete curing chamber is generated using our own CHP (combined heat and power unit). It is much more efficient to produce electricity for our factory using this process. The resulting electrical energy is used to operate our production facilities and any additional requirements are supplied from our factories’ photovoltaic panels.

Photovoltaic systems on the roofs of Glatthaar Keller sites and CHPs in the precast factories produce more electricity than is consumed. For example, last year the PV system at the precast concrete plant in Neuwied generated 269,256 kWh, while 85,761 kWh was consumed. In 2020 the Neuwied concrete plant’s renewable energy systems generated 511,649 kWh of green electricity. 235,443 kWh were used for the production processes. The rest was fed into the grid. With the completion of the new administration building in Simmern (Germany) and its associated additional PV system, the company will cover its electricity usage from its renewable sources. It will be able to feed an additional 30 percent back into the grid. The technology could also be installed at other Glatthaar Keller locations.



Michael Gruben Says “When deciding on a building partner, builders today not only look for environmentally friendly products, but also to the sustainable practices that go with them. That is why Glatthaar Keller has a clear sustainability strategy, which means moving more and more into the customer decision making process, so that we can have a direct influence on their environmental footprint. It is important to us, to optimise the products ecologically, and, to take our employees and customers along with us on our sustainability journey. Because the fact is, it can only work if our colleagues and customers are ready.  For us, the sustainability measures must be continuously readjusted, which requires a permanent systemic and strategic approach. The Glatthaar Keller brand stands for responsible social action, which is why we are creating the new job role of “Sustainability Manager” to embed sustainability firmly into our corporate culture. We must keep thinking ahead to ensure the long-term success of our company. “
