Limiting waste

Lafarge takes a two-pronged approach to limiting waste: it recycles production waste and reduces construction waste.

Recycling production waste

Year after year, the Group increases the proportion of production waste it recycles. Products suitable for recycling include substandard plasterboard and cement with kilning defects.

Plants reuse such products as:

  • alternative raw materials,
  • or alternative fuel.

 

The Cement Business has created a "Resource Recovery" team dedicated to industrial ecology.

Reducing construction waste

To accomplish this, Lafarge:

  • designs materials which "save" on raw materials, such as project Aether. This new class of clinkers requires less limestone and can be manufactured at lower temperatures and with less energy. CO2 emissions are cut by 25-30%.
  • promotes the recovery of waste on construction sites.

 

Lafarge is committed to reducing the amount of construction waste sent to landfills. We generate a consistent but low level of waste.

Recycling

Saving building materials
In France, the recycling platform near Pontreaux has been able to spare up to 80 kt/year of virgin aggregates
from nearby quarries.
In Korea, Lafarge recycled 100% of production waste and 55% of waste generated during construction, which represents 4% of the total raw gypsum consumed in its 3 plants.
