Corporate Social Responsibility is not just about looking ahead and towards the future to determine how to drive your business. For a company like DONG Energy (Denmark’s largest energy provider) it also involves taking responsibility for the past. 10 years ago, DONG Energy initiated a remediation project. Not because they were required to, but rather, because they had an ambition to preserve clean drinking water in Denmark.
Torrential rainfalls have become part of everyday life in Denmark, due to climate changes. However, our cities are not dimensioned for heavy rain. Therefore, it is necessary to develop our cities and make them more resilient against the still escalating volumes of water. Randkløvehuse, a housing association in Tårnby, has previously struggled with large volumes of water in the basement after torrential rainfalls. In order to prevent future floodings, green storm water infiltration solutions, which are able to absorb large volumes of water, have been installed. The climate proofing solutions applied to the project contribute to a sustainable city development.
Copenhagen is booming with various construction projects – transforming the city into a modern metropolis. The largest project of all is the construction of the Metro Cityring. In close cooperation with Metroselskabet, Geo has undertaken the largest and most comprehensive geotechnical site-investigation ever, in order to ensure the best possible foundation of the new metro line.
Interxion is a leading European provider of cloud- and operator neutral data centres. For Interxion sustainability is in focus, which is why a deliberate choice has been made to pursue energy efficiency and green solutions, wherever possible. 100% of the company’s energy consumption stem from renewable sources such as hydro energy, solar energy and wind power. However, why stop there?
The Munkholm Bridge is an important link across the Isefjord. Many lightweight- and heavy vehicles cross the bridge on a daily basis, making the Munkholm Bridge essential for commuters, among others. With its three simple concrete arches, the 114-metre long bridge connects the Holbæk area with the Hornsherred peninsula in an idyllic landscape. However, below the bridge’s eastern abutment the idyll ends. Throughout the lifespan of the bridge, the eastern abutment has settled more than 0.5 metres, causing significant strain to the bridge.
Up until the 1980s, it was common practice in Denmark to use former gravel pits as landfill sites for residual waste. Among others, the waste consisted of organic household waste, which over time degrades to landfill gas (LFG,) which contains methane and other gasses. The LFG is able to migrate into buildings and poses the risks of choking and explosion. At the landfill ‘Stengaarden’ in Hvalsoe, the Region of Zealand has installed a remediation plant to manage the migration of LFG. Geo has participated in the installation of a plant, which manages the gasses that are posing a risk.
In many Danish cities, construction has changed severely over the last years. We build taller and taller and the buildings often include deep basements with several floors. Deep excavations and dewatering systems are required. However, in a few Danish cities an underground of plastic clay complicates construction even further and influences costs considerably.
In China, the rate of urbanization has embarked on a fast track and old contaminated industrial areas are vacated in order to make space for residential development.
Numerous challenges present themselves during the construction of offshore wind farms. Detailed mapping of the seabed as well as knowledge about the foundation properties are the key to a successful project. These aspects are important in order to design and build the best and most cost effective foundation for the wind turbines. Choosing the proper site investigation methods and equipment from the beginning, is crucial in order to optimise the entire foundation solution.
Denmark can be self-sufficient with energy for decades to follow, if it is possible to produce the very large oil- and gas deposits, which still exists deep below the seabed. So far, it has been too expensive and complicated to recover oil from great depth, why new technology is required, in order to make this possible. The success of the project can dramatically alter the future energy supply of Denmark.
Ranking amongst the top 10 elite universities in Europe requires a high-level of ambition – an ambition, which is present at The Technical University of Denmark (DTU). To perform high-level research and education of the engineers of the future is, however, an energy-consuming task – also literally speaking. This is why DTU determinedly seeks to implement sustainable solutions to e.g. the field of energy consumption, in which the cooling of super-computers and laboratories make up for one of the largest entries in the overall energy score. However, why look ‘far and wide’ for new innovative technology, if the solution can already be found below the surface?
