The life cycle analysis - sustainability in underground

Every product can be related to the environmental impact of its production, use or disposal. The steadily growing awareness of environmental protection in recent years has led to a lively interest in the "ecological footprint" of products and services. In order to make this so-called footprint both accessible and quantifiable, valid methods for evaluating a product's life cycle have been developed: the life cycle assessment study. The internationally used, equivalent term of Life Cycle Assessment (LCA) has also become established in Germany.

Residual styrene content in CIPP samples - 
Measurement methodology and effects

Since the advent of styrene-curing CIPP resins, the industry has been concerned with the issue of "residual styrene content". Be it clients, environmental protection, contractors whose performance may be called into question, or structural engineers and engineering consultants or structural engineers and engineering consultants who cannot provide structural proof of the final product if the curing process is inadequate. This This technical report sheds light on the background, provides information on the measurement methods to be used, and looks at the effects of non polymerized styrene on liners and the environment.

Modern sample management in the testing of pipe liner samples. 

We are all regularly flooded with statistical evaluations and information. This is all well and good in order to allow interpretations and to make decisions. However, in most cases the central statement is strongly dependent on the data basis, which cannot be influenced. In short, statistics must be believed unconditionally.

Quality assurance of vertical liner systems

The success rate of trenchless rehabilitation using pipe liners is impressive. However, according to DIN EN 752, the aim of rehabilitation must be to seal the complete system against exfiltration and infiltration, which inevitably raises the question of the tightness or functionality of the transfer points and manholes.
