Malaysia - Biomass to energy

Lafarge's cement plants in Malaysia use wood processing by-products and Construction and Demolition woodchips as an alternative fuel in their kilns, reducing fossil fuel consumption, CO2 emissions and fuel costs.

 

Objective

  • Reduce fossil fuel consumption
  • Provide a disposal solution for the organic waste generated by the agricultural, timber, furniture and construction sectors

Summary

Lafarge uses biomass waste as alternative fuel in its Malaysia plants, allowing it to reduce fossil fuel consumption and associated CO2 emissions. The waste comes from the agricultural, timber, furniture and construction sectors in both Malaysia and neighboring Singapore. We work with a number of waste-treatment companies that source the untreated biomass waste. We have installed the necessary equipment at our cement plants to receive and store this waste and feed it into our cement kilns as a substitute fuel for coal.

The biomass waste generated from the agricultural, timber, furniture and construction sectors poses a disposal problem for the industries concerned and in the past was commonly land-filled or burned with no energy recovery. Using this waste as alternative fuel therefore provides a disposal solution while also allowing us to reduce the amount of coal – all of which has to be imported – that we burn in our cement kilns. 

Results

Our Rawang, Kanthan and Langkawi cement plants have achieved approximately 15 %, 18% and 9% replacement of fossil fuel by alternative fuels, most of which are carbon-neutral biomass. This has allowed them not only to lower their fuel costs, but also to reduce CO2 emissions by around 200,000 tons per year.
