Two years ago she won bronze – this time the medal shines golden! The Wendlingen hammer thrower Aileen Kuhn from Eintracht Frankfurt impressively secured the gold medal at the U23 European Championships in Bergen, Norway, on Friday evening, confirming her role as Europe’s best athlete of the year.
Even before the competition, Aileen Kuhn was considered a promising candidate for the European title with her season’s best. However, her first attempt got off to a turbulent start: although her hammer flew well over the 70-meter mark, the throw was invalidated. However, the 21-year-old did not let this upset her. A safety throw of 69.14 meters in the second round brought her third place.
She then found her rhythm in her third attempt: with an impressive 71.70 meters, she catapulted herself to the top position. But that was not all – Kuhn even went one better in the fourth round and improved her best performance of the year to a strong 72.53 meters. This put her well ahead of her competitors, as distances of over 70 meters were also required for the other medals this time. Silver ultimately went to Nicola Tuthill from Ireland, who also put in a strong performance with 70.90 meters.
“I’m extremely proud that I was able to win here as the favorite,” explained Kuhn after her triumph. “I was a bit nervous after my first invalid throw, but after that I was able to improve step by step. The atmosphere here got better with every attempt and really pushed me.” It was particularly impressive for her that three athletes exceeded the 70-meter mark: “Two years ago I won bronze with 68 meters, this time not even 70 meters was enough for a medal – that shows how strong the competition has become.”
A decisive factor in Kuhn’s improved performance was also the change in her technique: together with her new coach Kathrin Klaas, she switched from three to four spins. “That also explains my improved performance,” explained the newly crowned European champion.
Innovation in track cleaning: How Sandmaster is setting new standards with its mobile water filtration system
Awarded at the BMWE Innovation Day: ‘ZIM Cooperation Project of the Year 2025’
At the Innovation Day for SMEs organised by the Federal Ministry for Economic Affairs and Energy (BMWE), Sandmaster was awarded the prize for the ‘ZIM Cooperation Project of the Year’. The reason: a unique, innovative project for the sustainable purification of process water used in the cleaning of plastic tracks – Sandmaster’s mobile water filter system.
But what exactly is behind this innovation? Why is it so important? And how does it work in detail?
The challenge: water consumption and environmental risks associated with track cleaning
Professional cleaning of plastic running tracks is essential to maintain their durability, slip resistance and functionality. High-pressure water cleaning systems are generally used for this purpose. The problem is that this process produces large quantities of contaminated wastewater containing microplastics, fine dust, moss, algae, suspended solids and, in some cases, environmental residues that are washed out of the coarse-pored soil.
For Sandmaster, as an environmentally conscious company with high standards of innovation, this was reason enough to look for a solution.
The solution: a mobile water filtration system for immediate use on site
In close cooperation with a specialist environmental technology partner, we have developed a mobile water treatment system that can be integrated directly into the cleaning process. The highlight: the waste water produced during the cleaning process is filtered, purified and reused on site – without the need for external disposal.
Key technical data:
Multi-stage filter system: The water passes through several filter stages until it reaches the final microfiltration stage. What remains is a solid mass, which is disposed of properly.
Retention of microparticles: Microplastics and fine solids are reliably removed down to the µ range – an important contribution to environmental protection.
Real-time water recycling: The purified water can be fed directly back into the cleaning cycle.
Compact, mobile design: The entire system is housed on a trailer and can be used flexibly on any sports field.
Sensors and monitoring: Integrated sensors continuously monitor the degree of contamination and filter performance to ensure maximum efficiency. You receive detailed documentation: comprehensive wastewater management with information on the amount of cleaning, degree of contamination, pH values and volume of the remaining solid matter for disposal.
Sustainability with measurable impact
Thanks to this technology, fresh water consumption can be reduced by up to 80% – a significant ecological and economic advantage for operators of sports facilities. In addition, external wastewater treatment is no longer necessary.
A cooperation that sets an example
The project is a prime example of how genuine innovation can arise from cooperation between medium-sized companies and technology partners. The BMWE recognised this achievement with the ‘Cooperation Project of the Year’ award, thereby setting an example for sustainable technology development in medium-sized businesses.
Outlook: More than just sports facilities
Sandmaster plans to expand these and other technologies currently under development in the future – the aim is to continuously improve the environmental performance of cleaning technology and significantly reduce the CO₂ and water footprint.
Conclusion: Technology that connects the environment and the economy
With its mobile water filtration system, Sandmaster demonstrates how modern technology, environmental responsibility and operational efficiency can be successfully combined. The award from the BMWE is not only recognition of the company’s innovative achievements, but also an incentive to continue along this path. Conclusion: technology that combines the environment and the economy.
“Sustainability must not be an add-on – it must be an integral part of our solutions.”
At night, when everyone is asleep and recovering, the work begins for the colleagues from #teamsandmaster. In the legendary ‘Stade de France’ in Paris, a rugby pitch had to be dismantled within one night and the plastic floor had to be cleaned sparkling clean and all residues removed. Sandmaster just rocked it!
In addition, the synthetic flooring is cleaned with special machines and thus has optimum functional sports properties every day.
Sandmaster’s involvement in the Summer Games was also reported in various daily newspapers, below is an extract:
On Tuesday, 2 July 2024, we held the fourth press conference with Malaika Mihambo at the Sandmaster site in Wendlingen. Numerous well-known journalists were invited to conduct exciting interviews. In addition to ARD, SWR and ZDF, we were also able to welcome dpa, Eurosport, Sport1 and many more.
Malaika is considered one of Germany’s gold medallists for the upcoming Olympic Games in Paris.She recently won gold at the European Championships in Rome, but then had to sit out the German Championships due to coronavirus.
We are keeping our fingers crossed for Malaika and wish her every success in Paris. There was also a small gift, which was presented by our CEO Mr Christoph Mayer-Klenk.
Durable and unique protection for your sand surfaces
Sand cleaning is essential to extract organic and inorganic waste and aerate the sand to restore the biological balance.
In order to keep the sand areas clean in the long term, however, a sand cover is absolutely recommended, because otherwise waste and animal excrement will quickly collect again. In the worst case, dangerous components such as broken glass, screws, syringes and other impurities that can be dangerous for athletes or children playing.
For this, we offer unrivalled covers in high quality. The special feature, apart from the extremely robust and durable material, is the possibility to print the cover according to your wishes. This can be full-surface photos, illustrations or club logos or, of course, sponsor logos. A great and large advertising space at your disposal.
CUSTOMISED SAND COVERS OF THE HIGHEST QUALITY
MASTER COVER is a sand cover of the highest quality, made of robust and durable material that can withstand all weather conditions.
The net is made of fine-meshed polyester coated with PVC and is highly durable. The mesh structure allows optimal air circulation and prevents moisture from accumulating under the cover, which prevents the formation of mould and fungi. At the same time, the mesh size is small enough to prevent dirt such as leaves or animal droppings from getting into the sand. The border is made of a PVC-coated, UV-resistant tarpaulin fabric that is extremely robust and durable. The sand covers are tear-resistant and ideally suited for outdoor use. They can even be walked on without hesitation.
Each MASTER COVER cover is manufactured according to your individual needs and requirements. In doing so, we take into account the size, shape and desired imprint. Before we deliver the custom-made sand covers to you, they go through a strict quality control to ensure that they meet our high standards.
An investment in a high-quality MASTER COVER sand cover not only ensures years of enjoyment, but also sand surfaces that are protected all round.
