Canada - Lafarge-WWF local partnership to develop the use of biomass

Bath

Cement/Canada

With WWF Canada, our cement plant in Bath, Ontario is working to produce its own fuel by growing crops to produce biomass. The aim is to develop biomass as a large-scale substitute for coal that is currently the plant's main fuel source.

 

Objectives

  • Develop crops which can be used as alternative fuels on the site of the Bath cement plant
  • Replace fossil fuels (coal and petroleum coke) with biomass, carbon-neutral fuel, to supply the cement plant and reduce its CO2 emissions

Summary

‘Energy Farm’ project. This project aims to use our Bath cement plant's unoccupied land to grow crops and transform the biomass produced into energy, replacing the existing energy sources – coal and petroleum coke. Research has focused on:

  • The most appropriate crop species
  • The most economical production techniques Long-term obstacles, in particular the impact on food crop production Water management Wildlife protection
  • The aim is to develop biomass as a large-scale substitute for coal that is currently the main fuel source for our Bath cement plant.
  • The project is supported by Ontario's Environment Ministry which has set itself a target of reducing CO2 emissions by 17% between 2005 and 2020.

 

Results

An initial transformation test saw the successful use of 500 tons of biomass as a substitute for fossil fuels, reducing CO2 emissions by 1,000 tons. We are now working on a large-scale test program with a fuel demonstration plant that has been built at our Bath cement plant. The work carried out in Bath is acting as a pilot which may be duplicated many times and serve as a development model for other industries in the region.
