2021 Amsterdam : FLOWABLE FILL FOR PLASTIC PIPEAuthor(s) : Amster Howard
Flowable fill is used for many applications, but mainly for pipe trench embedment and
backfill. There are three ways that using flowable fill can be kind to the environment.
Because flowable fill is self-leveling and has a strength greater than the native soil, the
trench cross section can be minimized. This means...

Environmental Product Declarations of e.g. building products are to a large extent
mandatory and we see that the European Union as well as individual Member States are
implementing new regulation to secure sustainability in new buildings. The European
Commission’s Product Environmental Footprint is one example and...

The application of recycled material in pressure piping systems has been considered
lately – it was suggested, that the recycled polyethylene could be used as a part of a
multilayer pipe together with virgin material. This type of pressure pipes is not availableon the market yet, so their properties can be only...

Plastic pipes are of outstanding importance for the distribution of potable and
process waters, oil and gas, as well as for sewer and waste water disposal. However,
plastic pipes are also used in many other technical areas. Especially in European
countries with mountainous regions, such as Austria, Switzerland, Italy...
2021 Amsterdam : RECYCLING COMMITMENT OF THE EUROPEAN PLASTIC PIPE INDUSTRYAuthor(s) : Ludo Debever, Peter Sejersen
The European Plastics Strategy is a priority for the European Union. Recycling more post-
consumer plastics (PCRs) is paramount. That is why the Circular Plastics Alliance has been
established. The alliance gathers public and private stakeholders in the plastics value chains to
promote voluntary actions and...
2021 Amsterdam : Risk Assessment of Non-Intentionally Added Substances (NIAS) in potable waterAuthor(s) : Dr Ruediger Liske, Dr Tobias Eltze, Dr Tania Weyland, Marie-Laure Bertet
The migration of NIAS (Non-Intentionally Added Substances) into potable water is a
recurring topic for the distribution of cold and warm drinking water and related materialsindustry. These substances are chemical compounds that are present in drinking water
contact materials but have not been added during the...

The Cyclic Cracked Round Bar (CRB) Test has been applied to study the slow crack growth
(SCG) resistance of virgin, recycled, and reprocessed PVC-U. This fracture mechanical test allows a
quick ranking of the SCG resistance of PVC-U. A clear correlation between the K-value and the SCG
resistance has been elaborated....
2021 Amsterdam : UTILIZATION OF HDPE RECYCLED MATERIALS IN SANITARY SEWER APPLICATIONSAuthor(s) : John M. Kurdziel
The use of recycled plastics in high density corrugated polyethylene pipe for storm
sewers, highway culverts and general land drainage applications has now been widely
accepted by municipalities and transportation agencies. This acceptance has made it
possible to convert what was once considered a single use plastic...
2018 Las-Vegas : Innovative design of the atlanta braves baseball fieldAuthor(s) : Jim Goddard, Issam Khoury, Mark Heinlein
The Atlanta Braves Major League Baseball team built a new stadium north of Atlanta, Georgia. The field drainage design required the removal of 75mm (3 inches) of rainfall an hour and a system for warming or cooling the field using air blown through the drainage system and field profile using heat from pipe buried...
2018 Las-Vegas : Multilayer polymer pipes - Possible utilization of recycled materialAuthor(s) : Pavel Hutar, Jan Poduska, Pavol Dlhy, Andreas Frank, Jaroslav Kucera, Jiri Sadilek, Gerald Pinter, Lubos Nahlik
This paper investigates possible use of recycled material as a part of a multilayer polyethylene pressure pipe system. Crack propagation in different configurations is simulated. Lifetimes of pipes containing recycled material are calculated. Results are compared with lifetimes of pipes made of virgin...

In order to improve the circular economy of polymers in terms of sustainability and reduced carbon footprint, the increased use of recyclates has become a topic of major importance. Due to their long design lifetimes, pipe applications represent an excellent opportunity to create added value to non-virgin polymers. In...
