DE Environmental assessment of grid expansion in Germany
The expansion of the German extra-high-voltage grid is a crucial building block of the energy transition—and it is taking place now. Nationwide, planning, permits and construction work are running in parallel. A significant part of the new lines is already in operation, and further sections are under construction or are about to be approved. In total, […]
Converting Waste Streams Into Resources: Circular Solutions for a Changing Europe
Europe stands at a critical turning point: waste is no longer an unavoidable by-product—it is a resource stream waiting to be unlocked. With the EU generating more than 2.2 billion tons of waste annually, and recycling rates stagnating at around 49%, the shift from a linear to a circular model is now an economic, environmental, […]
Cold local heating network with geothermal energy for the new residential quarter in Gronau (Leine)
Development of sustainable district energy: Cold local heating network for Gronau (Leine)
The development of climate-neutral residential districts requires engineering solutions that go beyond conventional supply concepts. While cities and municipalities are looking for cost-efficient, low-emission energy solutions, cold local heating networks are becoming increasingly important as a central component of sustainable urban planning.
The state of municipal heat planning in Germany: Progress, Challenges and Outlook
Introduction: Germany’s path to climate neutrality is gaining momentum – and municipal heat planning has become one of the crucial elements for a sustainable energy future. Since January 1, 2024, the Heat Planning Act has required every municipality to develop its own heat plan. This process not only lays the foundation for a decarbonized heat […]
Environmental effects of plant protection products: Entry pathways, risks and protection strategies
Plant protection products (PPPs) have been a key tool in agricultural production for many decades. They protect plants from diseases, pests and unwanted competing vegetation. At the same time, they are released directly into the environment in large quantities. This makes an expert assessment of their effect on soil, surface water and groundwater indispensable. Prof. […]
Exploration of a suspected landfill site in Leer – M&P Hannover
Exploration of a suspected site of old landfills from historical research and exploratory investigation to basic waste characterisation and hazard assessment – using the example of a site in Leer M&P Ingenieurgesellschaft Hannover – a member of the SIERA Alliance – was commissioned to carry out a detailed investigation of a site in Leer as part […]
Air monitoring in contaminated areas: safety with PID measurements
Remediation and exploration work in contaminated areas places high demands on occupational safety. Gases and vapours that remain invisible to humans can have dangerous effects even in small quantities. This is why continuous monitoring of breathing air is of central importance. Modern measuring devices make it possible to recognise acute risks such as fire and […]
Restoring Rivers in Thuringia: Nature-Based Watercourse Development
Restoring Watercourses in Thuringia: How Nature-Based River Development Strengthens Ecosystems and Communities Across Thuringia, watercourses such as the Linderbach, Gramme and Erbstrom are at the centre of ambitious ecological development initiatives. Although these rivers belong to the second-order watercourse system, their environmental relevance is far greater—they shape local biodiversity, influence flood dynamics, and serve as […]
