Think about tomorrow today
KUTTER not only stands for an efficient and modern way of working, but also always has the environment in mind. With a wide variety of technologies, we are careful in every area to work as resource-saving and climate-friendly as possible. With the Green Shovel we mark special projects and processes, because as a construction company we are aware of our responsibility towards our planet.
On this page you can see where we are already thinking about tomorrow and which processes are used.
WE DRIVE WITH HVO
our vehicle fleet is also becoming sustainable
It is very important to KUTTER to conserve energy and its resources. Since KUTTER is already quite well positioned in many areas, it was important for us to take a closer look at our largest source of energy, namely the KUTTER fleet and the mixing plants, and to look for a way to make them future-proof and energy-efficient. In order to act in a sustainable and resource-saving manner, we have to significantly reduce the amount of fossil fuels used.
We came across the topic of HVO and the Finnish company NESTE, which produces a sustainable fuel. This is mainly obtained from renewable raw materials, fatty acids, residual and waste materials as well as municipal waste - the whole thing is called HVO, which stands for Hydrotreated Vegetable Oils. What this is all about in detail is explained to us by Dr. Markus Mohrdieck, Head of Safety and Environment at the KUTTER Group, in this video.
However, anyone who now thinks of a type of biodiesel when it comes to HVO is wrong! Chemically, HVO is absolutely identical to fossil diesel, which is obtained from crude oil using refinery processes. HVO does not contain any aromatics, which contribute significantly to fines pollution. CO2 emissions with NESTE fuel are reduced by 90%. This is due to the use of regenerative raw materials. The emitted carbon circulates in NESTE HVO fuel. The new fuel is not yet approved in Germany, but it can be used in company-internal refueling under certain conditions. Currently, use is mainly limited to heavy commercial vehicles and public fleets. In the first step, KUTTER is planning the more climate-neutral HVO fuel for various vehicles of different sizes, so that KUTTER's CO2 footprint is significantly reduced.
The benefits are enormous
The HVO fuel even offers advantages over the commercially available – i.e. fossil – diesel. It is odourless, can be stored for a very long time and has a "better" water hazard class (WHG I) than conventional diesel. This means that significantly lower requirements have to be placed on storage. Thanks to its clean combustion, we hope to reduce the maintenance intervals for vehicle exhaust gas cleaning. Even cold winters, which are common in the Allgäu, our vehicles with HVO survive better, since conventional diesel often thickens in cold temperatures and thus clogs the filters. Another advantage is that the new fuel is compatible with fossil diesel, which means that the other fuel could also be refilled. For us, all of this outweighs the higher specific price, because KUTTER is making an important contribution to the future.
Why doesn't KUTTER rely entirely on electromobility?
When it comes to cars, KUTTER uses electromobility wherever possible. However, electromobility cannot (yet) be applied to heavy-duty or commercial vehicles. Furthermore, the charging infrastructures on construction sites are not yet available. As a company, we are simply convinced that the energy transition cannot be achieved simply by concentrating on e-mobility or even hydrogen.
Open to new
We are pleased that we have found partners in NESTE and the distributor EDI with whom we can operate our fleet in a future-proof and resource-saving manner and we continue to strive in all areas of the company to create sustainable solutions.
From old to new
Our goal is to be able to convert as much old asphalt granulate as possible into new asphalt mix. So we not only practice recycling, but always strive for a suitable upcycling by processing between 50 - 100% old asphalt. This is made possible by proactive demolition work, in which we rely on milling in layers, even if it was not advertised by the client. Thanks to the modern plant technology in the asphalt mixing plant, e.g. B. a parallel drum and an increased sampling and analysis effort in our own laboratories, this project can be implemented expediently.
REDUCING CO2-EMISSIONS IN ASPHALD PRODUCTION
WE REDUCE CO2 EMISSIONS BY APPROX. 10%
Dry storage (indoor storage) of recycling materials (smaller than 8 mm in diameter) reduces CO2 emissions during asphalt production by around 10%. The halls are used to keep the used asphalt in the form of milled material that is to be mixed in during the asphalt production process dry and warm; the incineration process therefore requires significantly less energy and fewer raw materials are used. Storage is often in tents; However, we made a conscious decision to build halls so that the roof areas can optionally be covered with a PV system.
THE COOL AMONG INSTALLATIONS
In road and asphalt construction, the paving of temperature-reduced asphalt can lead to a reduction in CO2 emissions of around 13%. According to literature and measurements in other European countries, up to 40% are even possible. Unfortunately, the construction method is currently still very rare, since this variant must be explicitly requested in tenders. As a construction company, we cannot determine the installation variant. The use of temperature-reduced asphalt makes sense above all on construction sites with a short construction time (< 10 hours).
THE AJF CONTAINER
KUTTER TRANSPORT CONCRETE SAVES MONEY AND TIME WHEN HANDLING RECYCLING WATER
In the field of ready-mixed concrete, KUTTER relies on cooperation with the company AJF. This offers filter systems that treat the existing recycling water that is produced by cleaning the mixers and the system and feeds it back into the concrete production. This results in enormous savings in fresh water/drinking water, since the water density in the concrete has to be reduced, especially in winter. This additional requirement can now be absorbed by recycling water.
Low-resource heating and cooling system
We rely on well water
Heating and cooling - without using resources such as gas, oil or pellets. With our thermal heating system, we create an optimal working climate for our employees in the truest sense of the word. We use deep water, which is taken from wells created by baugrund Süd in Bad Wurzach and circulated in our administration building using a heat pump. The offices and meeting rooms can be tempered in an absolutely environmentally friendly way. Our data center is cooled in this way. Here, KUTTER works together with the regional company Alois Müller, which specializes in flexible energy solutions.
The system is currently supplied with external power. But that too will soon change with the construction of an in-house photovoltaic system. This is already planned, so that we can also use self-generated green electricity here.
Quality, flexibility and reliability have always been our values, which we live every day anew. Well-trained employees and modern machinery ensure that services are carried out sustainably, economically and professionally.
So we at KUTTER - and you - have the guarantee that all requirements are met responsibly, sustainably, economically and efficiently.
