Optimization of energy sources

Cement companies can offer local waste recycling solutions to communities and industries. Vicat strongly promotes these solutions in order to reduce the use of fossil fuels.

Montalieu Plant in Isère (France)

Cement plants possess industrial tools that process waste in line with constraints relating to environmental, sanitation and security regulations. 
These tools constitute technical and environmental advantages that are indispensable to the complete disposal of waste: very high temperatures (flames producing heat at 2,000°C), prolonged oven time, guaranteed compliance with standards relating to emissions in the atmosphere, etc. 
Moreover, the process generates no final waste output (such as ash or slag), resulting in the full recycling of waste (energy and raw materials). 

Refuse-derived fuel preparation plant

Waste accepted into a cement plant meets strict specifications (chemical composition, granulometry) and requires specific preparation stages (sorting, grinding) to ensure adherence to industry cement manufacturing quality standards.

Since the 1970s, cement plants have been recycling several types of waste: used oils, non-chlorinated solvents, tires, residual waste from compacted cars, bone meal, ground timber, SRF (Solid Recovered Fuel) and sludge from wastewater treatment plants. These are sustainable and local solutions that avoid the use of incineration and landfills to dispose of waste.

The Vicat Group allocates an increasing share to fuel alternatives. In 2010, the rate of alternative fuels used outside India and Kazakhstan was 15.5% compared to 13.6% in 2009. 

The Vicat Group developed this activity with an awareness for the removal of natural resources, energy costs and a willingness to engage in a dynamic and active management of environmental considerations.

Several projects are ongoing in Turkey, Senegal and Switzerland, allowing the Group to increase its use of these fuels. 

The recovery of energy and materials for fuel alternatives in cement plants is part of a sustainable development orientation and aims to reduce: 

  • extractions of natural resources
  • greenhouse gas emissions
  • fuel fossil consumption,
  • quantities of waste incinerated or placed in landfills.
