Installation of light columns to limit energy consumption

Because plastic injection is the most electricity-intensive phase of production, Plastic Omnium has implemented visual management systems (light columns) to optimize its electricity consumption.

Project objectives

Implementation of visual management systems such as light boxes in its injection production areas to optimise energy consumption and avoid wastage.

Detailed project description

To contribute to Plastic Omnium’s objective of reducing its scope 1 and 2 GHG emissions by 20% in 2025 compared with 2018, the Company is seeking to reduce its energy consumption and environmental footprint.


The plastic injection moulding machines are the most energy-intensive areas (in terms of electricity from the national grid) of the production sites.


The purpose of the light columns is to make the users of the injection moulding production areas responsible for switching the presses on and off correctly. A lighted aid on each machine lights up differently depending on the data from the electricity meters:

  • In green: the press is working correctly, it is switched off or in nominal operation;
  • In red: the press is incorrectly stopped or consumes too much energy for its In this case, it is necessary to investigate the cause.


A last glass case is located at the exit of the site, if it is red, it means that one of the presses is incorrectly stopped.


Following initial feedback (from the Ruitz factory, Pas de Calais), it is planned to move these lighted aids to the communication and work area of the injection production unit (in addition to the lighted aid next to each press).

Emission scope(s)

on which the project has a significant impact

Scope 1

Émissions directes générées par l’activité de l’entreprise.

Scope 2

Émissions indirectes associées à la consommation d’électricité et de chaleur de l’entreprise.

Scope 3

Émissions induites (en amont ou en aval) par les activités, produits et/ou services de l’entreprise sur sa chaine de valeur.

Absorption d’émissions

Création de puits de carbone, (BECCS, CCU/S, …)

Émissions évitées

par les activités, produits et/ou services de l’entreprise ou par le financement de projet de réduction d’émissions.

Scope 2 – Better use of energy-using equipment

  • Quantification : – 12 tCO2eq/year  

The Fontaine plant estimates a gain of 200MWh of electricity per year (i.e. approximately 3% of its total annual electricity consumption). An emission factor of 0.06 tCO2/MWh is considered for the electricity consumed on the French grid.

Illustrations of the project

This project will :

  • Increase the life span of the equipment
  • Reduce maintenance requirements
  • Reduce HSE risks (noise, fire, etc.)

The project has strong replication potential across the division and the Plastic Omnium Group. It requires many actions to control the start-up and shutdown of equipment.

This project requires:

  • The involvement of all management
  • Regular monitoring and promotion of good practices at the sites
  • An effective communication and sharing network within the division

A partnership with Schneider Electric (IRIO platform) has been initiated to implement energy monitoring solutions.
