Our contribution to environmental and climate protection: Sustainable. Far-reaching. Forward-looking.

Grenzebach continuously enhances the performance and energy efficiency of its high-tech systems to meet its ecological and economic responsibility to the environment and climate.

Through a range of innovative improvements, the company has succeeded in reducing the electricity consumption of cutting and stacking technology on float glass lines, also known as the “cold end,” by around 25 percent since the mid-1970s. Compressed air consumption also fell by a quarter in the same period. 

This not only conserves financial resources but also cuts carbon emissions.

The production of glass has always required a significant amount of energy. The main reason for this is the comparatively inefficient glass melting process. This is where the innovative waste heat recovery process (WHR) comes in. WHR systems use waste heat to generate electricity as well as heating and cooling energy for the process and air-conditioning purposes. Grenzebach and CNUD EFCO GFT’s patented WHR solution helps meet climate goals, conserve resources, and operate cost-effectively.

Countless insulation materials hold the promise of reducing energy consumption. Grenzebach supplies the complete production technology for the manufacture of organic or conventional, fire-resistant insulation materials – in other words, virtually all the building materials needed to construct an energy-efficient and modern house. In this context, wood chips or sawdust are transformed into high-quality, environmentally friendly, and easy-to-use materials for the insulation of buildings. Yesterday’s newspaper becomes today’s cellulose insulation material which can be installed as blown-in insulation or insulation board.

The use of FSW systems creates a safe working environment for employees, as this process does not generate dust, gases, or noise. Process materials such as shielding gas, powder, or welding wire are not required. In addition, it consumes much less energy than conventional welding processes and is also emission-free.

Numerous industries rely on this “green” Grenzebach technology. Especially in the context of e-mobility, our FSW solution lives up to the slogan “green technology for a green future.”

Grenzebach is a reliable partner that supports you throughout the entire product lifecycle. Providing first-class service doesn’t always require an on-site visit. Whenever possible, our service team avoids unnecessary travel, thus helping to protect the environment and combat climate change. We have been performing various maintenance and repair activities, upgrades, and modernizations via remote maintenance for many years. 

For you. For the environment. For the climate. Grenzebach is committed to environmental and economic sustainability in every phase of your project.

Why don’t we harness the power of the sun? Grenzebach found an answer to this question early on, installing the first solar power system in Hamlar in 2005. More solar power installations followed in the subsequent years:

• Solar panels on Grenzebach company buildings in Hamlar and Bad Hersfeld
• Total capacity of the systems: 1.2 MW
• Annual yield: more than 950 megawatt hours
• Carbon emissions saved: around 550 tons
• These systems can supply approx. 220 single-family homes with electricity per year

We’re already thinking today about tomorrow. Renewable energy is incorporated into all renovation measures right from the very beginning.

As a family-owned company with a vision, we develop sustainable recycling processes to conserve resources and protect the climate. With our experience in process technology and in cooperation with the scientific community, we quickly translate new research findings into efficient plant concepts.

Our phosphorus recycling process helps cities and municipalities recover vital phosphorus from sewage sludge.

The patented InnoTeer process recycles asphalt directly in asphalt mixing plants in a cost-effective and sustainable manner.
