Afvalzorg is always looking for fresh ways of innovating and maintaining its leading position while continuously pushing and exploring new boundaries in the field of landfill management. We work in close association with a number of universities, such as Delft University of Technology, Wageningen University, University of Hamburg, as well as with bodies such as the ECN (Energy Centre Netherlands) and scientists both at home and abroad.
Working in collaboration with ECN (Energy Centre Netherlands), Afvalzorg is currently developing a new, simple, and inexpensive method of measuring methane emissions, involving the use of gas cylinders. Known as the Static Plume Method (SPM), it has been successfully tested at landfills in the Netherlands and Denmark, and compares favourably with the scientifically proven Dynamic Plume Method (DPM).
Using the SPM, evacuated gas cylinders gradually fill with air consisting not only of oxygen and nitrogen, but also of methane and tracer from the landfill. The sampled air passed through capillaries into the cylinders and the process takes around five hours. The contents of the cylinders are analysed for methane and tracer in a lab. The results have shown that the simple and cheap SPM is no less effective than the scientifically proven and more expensive DPM.
When you want to perform a methane emission measurement to calibrate you landfill gas generation model or when you are required to perform in situ emission measurement, we can assist you exploring the possibilities for your landfill site.
