Landfilling is the final link in the waste management chain and above all it represents a source of renewable energy. To encourage companies and municipalities to adopt this form of waste recovery, our landfill sites use state-of-the-art techniques to produce heat and electricity whilst protecting the environment.
Highly sophisticated landfill sites
Leaktight geomembrane liners, leachate (liquid residue) collection and treatment systems, landfill gas recovery, strict environmental monitoring… Our landfill sites use the latest technology to guarantee environmental protection. In China, we operate several landfill sites, including the one at Guangzhou-Xingfeng, the first Chinese landfill site to comply with international standards. The South East New Territories Landfill (SENT landfill) is one of three strategic landfills that serve as the major disposal method for municipal solid waste generated in Hong Kong. At Chrzanow in Poland, we have opened the very first landfill site built to EU standards. We also operate Israel’s largest landfill site, which has been specially designed to optimize both landfilling costs and liquid residue treatment costs.
Landfill gas: a source of green energy
By 2010, 21% of each EU Member State’s total electricity consumption must be covered by energy produced from the fermentation of waste in landfill sites. With this in mind, Veolia Environmental Services has been selected by the French government to construct power plants capable of producing more than 12 MegaWatts of electricity. Our project: raise the output from the landfill gas conversion system at the Claye-Souilly site to 27 MW in order to reduce CO2 emissions by 42,000 tons each year. We also operate several similar landfill sites all around the world: Montreuil-sur-Barse (5.4 GWh, 4 million cubic metres of landfill gas), Saint Louis County, Eau Claire and Horicon in the United States, etc. Also, we have 5 landfill Gas-to- Energy projects in Mainland China and 4 facilities in Taiwan. In China, we are the biggest landfill gas-to-energy operator, our projects have taken up 75% of the total installed capacity of all landfill gas-to-energy projects.
Turning our attention to bioreactors
To further develop our waste-to-energy solutions, we are equipping our landfill sites with bioreactors that re-inject leachate into the waste mass. This system multiplies landfill gas production by 10 and increases the landfill capacity by 20 to 30%. In Australia, bioreactors have already been fitted at two of our landfill sites, including the Woodlawn site, which handles 400,000 tons of waste each year and produces 20 MW of green electricity. At La Vergne in France, we have launched a research program to measure the technical, economic and environmental benefits of this new landfill process on an industrial scale.
Protecting the environment
We introduce sophisticated measures and techniques at all our landfill sites in the aim of protecting the environment. One prime example would be Graulhet in France, where our hazardous waste treatment and landfill centre has been designed so as to blend into the local industrial surroundings whilst respecting the fauna and flora. At La Glacière, we carried out impact studies and adjusted our earthwork and development schedule accordingly. In Lapouyade, we backfill sites and then plant pine trees that help drain the soil and assist with reforestation. In Wisconsin (United States), we were involved in the rehabilitation of 95 hectares of prairie and wetlands to restore the original ecosystem.
Improving conditions for our neighbours
At St Aubin-en-Charolais in France, Veolia Environmental Services and the Environment, Energy and Waste Research Centre (CREED) measured the odors emitted by the landfill site and assembled a panel of local residents. By cross-matching the information collected with weather and operating parameters, we were able to map the site’s odors, identify where they were coming from and implement solutions to reduce them. We also provided local residents with a voice server linked up to a weather station and mapping software.
