LED relamping solution in Leclerc hypermarket in Midi Pyrénées

AES is currently developing a technology LED relamping in Leclerc hypermarket in Midi Pyrénées.

The objective of this collaboration is to reduce power consumption by over 40%.

In addition to reducing consumption, LED lighting will be more reliable and reduce maintenance palliative costs.

Indeed, the life of these products exceed 30,000 hours with  guarantees in support.

Biogas, for what purposes

Methanation Birth

In the context of the fight against greenhouse gas emissions, production development of renewable energy, waste recycling, the agricultural methanation  is a promising sector. This technique, which was an important development in a number of European countries, has potentially many interests:

  • biogas production, a renewable energy source ;
  • decentralized electricity production can generate network economies;
  • fight against greenhouse gas emissions by promoting biogas;
  • integration into a logic of territorial management of organic waste and recycling material ;
  • diversification of agricultural activity
  • for farmers, bio methanation allows to diversify the income of their operations;
  • positive image of the company with regard to the outside.

Reminder of bio methanation principle

Bio methanation is a simple enhancement of organic matter resulting from their degradation in the absence of oxygen and dark by the action of micro-organisms. This technique results in the production of a gas mixture called biogas, consisting of 55% to 70% of methane which can be used as a fuel and a digestate used as agricultural amendment.


What can we transform to produce « clean energy »?

  • Dung of livestock (manure, droppings,…)
  • Agricultural residues of vegetable crops
  • Slaughterhouse waste, cleaning fish, dead animals …
  • Outdated food shops (currently landfilled unsold!) …
  • Sludge from sewage treatment plants, septic contents, sewage, dredging
  • Algae, water hyacinth of ponds or canals (to rehabilitate!) …
  • Edible oils (fried) …
  • Food waste transformations (dregs of brewing beer …)
