Achieving climate targets – even in ice and snow
Environmental awareness in society is constantly growing. Today, companies and local authorities are increasingly faced with the challenge of implementing sustainable solutions to reduce their carbon footprint and achieve their own or legally defined climate targets. Quality and cost-effectiveness must not be neglected in the process. This is particularly true in the field of professional winter services.
A 100% sustainable gritting material that protects people, animals, and the environment
With CN WINTER GRIT, we offer a high-performance, abrasive winter gritting material for slippery surfaces such as footpaths, cycle paths, roads, squares, and parking garages. The expanded clay granules combine ecological and economic advantages and impress with their consistent sustainability:
- CN expanded clay is a natural product made from Leca®, based on pure mineral clays.
- The granulate is salt-free, non-toxic and can therefore be used without hesitation and without harming the environment.
- Expanded clay has no sharp edges that could injure animals with sensitive paws and does not damage floor coverings when it is brought into the home on shoes.
- Unlike other gritting materials, such as sand and gravel, CN expanded clay granules do not have to be swept up and disposed of by the winter service provider at the end of the season.
- It saves a lot of time because it can be conveniently swept into flower beds or green verges, where it also contributes to a sustainable improvement in soil structure and water permeability after the frost period.
- Since the granules are lighter than water, they do not clog the sewers when they enter the sewage system during thaws, thus preventing damage and conserving resources.
- CN WINTER GRIT has an unlimited shelf life and is 3.5 times more economical than sand or grit – another factor that makes it so sustainable.
- The low weight of this natural winter gritting material also helps to reduce CO2 emissions: significantly fewer trucks are needed for transport than for a comparable volume of sand or grit.
Holistically sustainable – from production to application
CN WINTER GRIT is continuously being further developed. This shows that sustainability does not stop with the product. In addition to its proven sustainability advantages, there are now further benefits relating to both the production and packaging of the winter grit.
In 2025, CO2 emissions during the production of expanded clay were reduced by over 30% compared to 2017. This was achieved, among other things, by replacing fossil fuels with bio-based alternatives.
The packaging of CN WINTER GRIT has also been further developed to conserve resources. The 50-liter bags are now made from 50% recycled material – a top value in the industry, where the average is significantly lower. And the development towards holistic sustainability continues and will gradually extend to the entire life cycle of the product.
Our tip:
CN WINTER GRIT is doubly worthwhile for professional winter services looking to offer their customers even more sustainable services: CN WINTER GRIT combines cost-effectiveness and environmental awareness in one product. It protects people, animals, plants, and soil – while helping to permanently reduce CO₂ emissions and resource consumption.
