Do something good for you and the environment

Environmentally friendly and sustainable ...

The demand for products that do not have a sustainable impact on the environment during manufacture, use and disposal is increasing in all product lines. This also applies to building materials. For this reason, the term “environmentally friendly” can be found on more and more construction products. However, very few manufacturers actually back up this advertising claim.

If we claim that our products deserve the label “environmentally friendly and sustainable”, then we prove it.

Regional is the best choice

We only use lime for the production of our sump lime from German lime deposits. The marble sands and marble flour that we use also come from rock deposits in Germany. The associated short transport routes have less of an impact on the environment. Especially since the German occurrence are among the purest limestone deposits in Europe. So we have lime in a quality of 98% Calcium carbonate available. Why do we need lime from Italy or Switzerland when the good is so close?

KalkKind - Made in Germany

We produce our lime in our own KalkKind factory in Oestrich-Winkel in the Hessian Rheingau. This is where we also produce all of the slaked lime materials. Our production facilities and main warehouse are therefore very central. This also ensures that our products do not have to travel unnecessarily long distances for delivery.


Lime is the second most common mineral on earth. Our lime products that we make from this raw material establish, stay free of plastics and other adulterating additions. This purity of sorts means that the materials can be recycled and the lime could start its cycle again after the usage phase.


Due to the fact that there are no plastic components, the surfaces do not have any components that can cause graying e.g. B. by Fogging would lead. The pit lime surfaces extend the renovation cycle. The walls and ceilings usually only need renovation when they are mechanically worn and damaged. But not because they would look unsightly after a few years. Thanks to their moisture-regulating properties, they protect the building fabric. Durability relieves the environment. Durability is another proof of the sustainability of building products.

Renewable raw materials

Not all surface design products can be made purely from minerals. Especially if, for example, the substrate is not suitable for pure lime. Should be old dispersion painteo the other plastic-containing If substrates are painted directly, an additional binding agent is required. For this we use additives based on renewable raw materials. Sugar, starch and xanthan are obtained from plants.

Shelf life without preservatives and fungicides

Most paints and water-based paints and plasters on the market use preservatives so that the materials don’t start to mold in the buckets. Preservatives are poisons that affect organisms and damage the environment. No preservatives or fungicides are used in KalkKind products. Due to the high alkalinity of the sump lime used, no bacteria and germs can form or multiply, which would make the materials unusable in the buckets. The lime has a pH of 12.6. Fours, germs and bacteria don’t like that at all.

Free of plastic and plastic

The plastics and other chemicals in building materials and Paint based usually on petroleum. Just up to the basic chemicals that are used today Mostly directly into the oil exploiters Countries will, worldwide the trip goes, became nature is already heavily burdened. The chemicals are then transported across the seas in huge tankers of more than 100,000 GRT and leave their environmentally damaging traces in our oceans.
So that, in the industrialized countries, individual substances and compounds can be produced from the basic chemicals by means of other additives, some of which are harmful to health and the environment. From these individual chemicals, the chemical industry then mixes the components together as they are needed by the building materials industry.
These are then called components. Sounds better too how “Chemical Cocktail”. Most of the paints and surfaces on the market are made from these Chemical mixtures that originally due to the use of petroleum.
Our lime products are free from plastic, plastic and other chemicals that are derived from petroleum.

Plastic becomes microplastic

Plastic is plastic – even if it is in emulsion paint, Silicate emulsion paint, in Plaster or filler is stuck. Microplastics are a major problem for the state of our oceans today. The ecosystems suffer from the constant increase in microplastics in Cycles. Increasingly large amounts are being found in our food and drinking water.
There are studies on all possible sources of microplastics: on cosmetics, cleaning agents, fertilizers, packaging waste, car tires and much more. There are hardly any studies on the proportion of microplastics that enter the environment via building materials and paints. But where is the plastic when building materials are torn down and disposed of after their useful life?
Where is the plastic when the paint brushes and paint rollers are washed out after work? Where do the plastics contained in the building materials go when the tools, buckets, agitators, sponge boards, smoothing trowels etc. are cleaned with water after the work is done. Even if sponges and cleaning rags that are used while working are washed out or thrown away, some of these chemicals are released into the environment.
What happens to the sanding dust that is generated during renovation, refurbishment and modernization? Inside there are lots of the finest plastic particles from the plastic-containing surfaces that were sanded. Let’s leave it with these few examples, through which every day thousands of tons of plastics end up in our wastewater or directly in the soil and thus in the environment.
The fact that these sources are hardly mentioned in the studies on microplastics is not due to the fact that the quantities that are released are insignificant. The lobbyists from the chemical and building materials industries are powerful. The greed for billions in profits is stronger than the duty to take responsibility for the environment and the climate. Not to mention the responsibility for the future of our children and future generations.

For the production of our surface materials, we KalkKinder do not use any Plastics a. We don't get into that.

CO² pollution from burning lime

When burning lime, CO² is released. Limestone consists partly of carbon dioxide. This part of the limestone is driven out of the rock by the burning process. This expelled portion of CO² is later absorbed from the ambient air as a lime plaster surface during the usage phase. This turns the lime surface itself back into limestone.
Because we do not use any additives in our lime products, we are on the safe side here. The carbon dioxide that is separated in the lime burning process is reabsorbed on the wall and ceiling. We are already using quicklime, which is burned in a modern lime works. Here part of the carbon dioxide is filtered off and used for the production of fine carbonate flours. This is how carbon dioxide becomes a valuable raw material.

The most ecological and environmentally friendly house is the one that is not built?

It certainly is. But if we take a responsible approach to the planning and selection of the materials with which we build, renovate, refurbish and modernize, then we contribute to improving the environmental situation and protecting the climate.

Building materials serve many purposes … they must not pollute the environment or damage the climate.
