Environmental analysis has to deal with the possible sources of error. It is known that the process of sampling is the major source of error (up to 90 % of the total error). The sampling error is scarcely considered, while the insignificant analysis error is included with up to three decimals. However, there are not yet any effective methods to reduce the sampling error, mainly because of the inhomogeneous properties of waste.
The aim of the project was to improve the sampling process with the same or an even higher accuracy of the analysis results.
The project targets a new technique to facilitate non-destructive sampling in waste bales. The current state-of-the-art sampling implements breaking up the bale, followed by tapering the samples. However this technique is time-consuming. Improving the sampling process should lead to higher accuracy of the results, since the process of sampling is the major source of error.
Five sampling methods were tested, including the state-of-the-art method, sampling with a chainsaw and different drillers of which the gained drilling cuttings are used as the sample. The most effective tool to sample a proper increment turned out to be a concrete core drill with a customised crown. Depending on the size of the bales, up to 20 increments can be obtained without compromising the stability of the bale. Hence, a non-destructive sampling technique is now achievable.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich
© Lexxion Verlagsgesellschaft mbH (8/2024)
Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
