2017 Veolia Performance Trophies: 9 students rewarded for their final projects

The 20th edition of Veolia's Performance Trophies rewarded 9 students (5 years’ higher education) for their work on subjects addressing the issues of water, energy or waste. Today at the Veolia headquarters in Aubervilliers, Group Senior Executive Vice President Human Resources Jean-Marie Lambert presented them with their trophies. This year the winners receive a trip to Sydney where they will meet Veolia employees and visit the Group's facilities in Australia.

Trophées performance 2017


In November, 21 students selected from 114 candidates from French and international schools and universities, presented their work to three panels of experts and Group managers in the "Performance", "Industry" and "Cities” categories. 
 

The 9 winners in 2017 and their final project

TP 2017 - Camille Barennes
 
Subject: Recovery of HDPE and PET plastic waste blends found in plastic bottles.
When the first sorting is completed, HDPE waste contains 3% PET impurities. If mixed with "pure" HDPE batches, it can be recycled by presenting the mechanical properties required to make everyday consumer goods (garden furniture for example). This recovery reduces costs by avoiding the need for a second round of sorting.


 
TP 2017 - Arthur Deprecq
 

Subject: Seawater desalination with half the energy.
The process developed to extract freshwater from seawater, which uses vaporization and solidification at water’s triple point, and consumes 1.8kWh / m3, compared to 3.5kWh / m3 required for the reverse osmosis process, or 15kWh / m3 by distillation. 
 

 
TP 2017 - Julia Nicol
  • Julia Nicol, from the École des Mines d’Alès, France – Performance / Internal (employee in Veolia’s Research & Innovation Department in Limay).

Subject: Identify new ways to recover the annual one million tonnes of cardboard collected by Veolia, which is now mainly recycled in paper mills.
Alternative solutions for recycling brown cardboard are studied here to increase their added value, with five demonstrators, in the insulation sector on the basis of cardboard fibres and the mechanical reinforcement of polymer matrices.
 

TP 2017 - Thierry Rigoine de Fougerolles
  • Thierry Rigoine de Fougerolles, Master in management from HEC-Paris (France) – Cities / External.

Subject: Comparison of urban waste management models in Taiwan and Hong Kong.
In South-East Asia, with its rapid economic growth and increased production of waste, the governments have adopted two distinct approaches: market-led management (in Hong Kong) or state-led management (in Taiwan). 
 



 
 
TP 2017 - Felix Sanchez
  • Félix Sanchez, from Arts et Métiers ParisTech (France) – Cities / Internal / Jury’s favourite (employee with Sade, a Veolia subsidiary).

Subject: Research on improving the methods used on building sites in urban environment.
It has been demonstrated that small improvements can yield significant results. For example, the optimization of pipe laying routes limits the amount of earth extracted and makes it possible to better plan the collection of the spoil.
 



 
TP 2017 - Peter Alexander Stentoft
  • Peter Alexander Stentoft, Master in Environmental Engineering at the Technical University of Denmark (Denmark) – Cities / Internal (employee in the Veolia subsidiary Krüger).

Subject: Wastewater treatment accounts for up to 10% of domestic energy consumption.
The aeration process accounts for more than 50% of the electricity used in the treatment process. A stochastic model predictive control strategy prioritizes aeration when green energy is available and downgrades it at peak times, reducing costs by 25%. This optimization process is currently being evaluated at the Central Jutland site in Nørre Snede, Denmark. 
 

 
TP 2017 - Camillia Sterpos

Subject: Technical-economic study of solar towers associated with micro-turbines to produce continuous electricity.
This study is based on the full cost of electricity, calculated over the lifetime of the equipment, depending on the temperature of the heated water.
 



 
TP 2017 - Dayana Serrano

Subject: Treatment of process water using the fern Azolla caroliniana Wild.
The salinity of the process water produced by the oil industry corrodes the equipment requiring the use of anticorrosive chemicals. This project experiments with reducing the salinity of process water by using the fern Azolla caroliniana Wild and a concentration of chromium.
