Energy-from-waste

Our cement production facilities hold Integrated Environmental Authorization and are all compliant with prevailing legislation on the integrated prevention and control of pollution (Spanish Act 16/2002) and Spanish Royal Decree 653/2003, which transposes Directive 2000/76/EC on the incineration of waste. This legislation envisages the use of waste to produce energy in cement kilns and the strict controls and emissions limits that must be met.Because of its characteristics, our production process can recycle different kinds of waste and use them to produce energy under optimum technical and environmental conditions without posing any risk at all to the health of employees or people living near our factories.

This way, the cement industry fully respects the waste hierarchy outlined in section 8 of Spanish Act 22/2011 of 28 July on waste and contaminated soil, which urges the competent government agencies to apply:

    1. Prevention,
    2. Preparation for reuse,
    3. Recycling,
    4. Other kinds of reuse, including EfW,
    5. And lastly disposal.
In 2012 we generated energy from meat meal, used tyres, plastic, coffee grounds, bits of crushed disused vehicles, solvents, sewage sludge, the rest fraction of municipal solid waste (RDF), plant pruning and clipping waste, plant biomass, industrial waste and used oil.

In that same year we boosted our rate of fuel replacement by waste by 4% in the Group as a whole. In Spain the fuel replacement rate is already 7%, which is nearly double our overall rate, and in the USA fuel replacement is growing daily, having now climbed to above 2%.

Why Do We Use Waste for Energy?
Because using alternative materials in the cement industry reduces overall CO2 emissions and has no negative impact on the production process, emissions or the technical quality of our end product.Last year using waste-derived recovered fuel enabled the cement industry to save more than 800,000 tons of CO2 emissions. It also achieved energy savings equivalent to 387,000 tons of oil, which is the same as the energy consumed in a year by 550,000 homes.The CO2 the Group saved in 2012 is equivalent to the emissions from using 54,000 vehicles for a year. And thanks to EfW, 131,000 tons of waste (equivalent to the space occupied by two football stadiums) never had to go to landfills.

We’ve Got a Long Way to Go
In Spain we recycle 22.4% of our waste (2011), much less than the European average. Countries like Austria, Germany, Norway, Switzerland and Belgium reuse more than 40% of their waste, and Holland reuses as much as 83%.
