From waste burning to energy recovery

Along with the development of the most selective treatment lines, the optimization of incineration equipments makes it possible, when other types of recovery are not technically or economically viable, to meet a dual demand: eliminate waste and produce energy.

Thermal treatment is an effective recovery solution for waste that cannot be recycled. The first advantage is that it divides the volume of waste by 10. It also provides an alternative source of energy that can replace fossil fuels to generate heat for district heating networks or electricity fed into the local grid. It saves natural resources and limits greenhouse gas emissions.

We are bringing our plants up to the most recent standards. We test and implement processes to minimize the environmental impact of our municipal waste-to-energy plants. We are also seeking ways to increase their thermal output by fitting them with electricity and heat cogeneration systems. We recycle the bottom ash as backfill and stabilize the flue gas residues. We pay particular attention to integrating new facilities into their natural surroundings.

An alternative source of energy

In France, the Nîmes waste-to-energy plant treats the non-hazardous waste from 57 municipalities. The plant is unique in terms of the performance of its flue gas treatment system, which yields emissions levels 75% below the regulation thresholds.

In Asia, our teams have won many contracts for the maintenance, operation or construction of waste-to-energy plants. For example, In Macau, where we obtained the first project in Asia, we operate the only municipal solid waste treatment facility for the city, specialized in Waste-to-Energy. In Taiwan, we manage the Bali plant which has a daily municipal waste treatment capacity of 1,350 metric tons for a power production of 41 MW. In Shanghai, we have provided technical assistance for the start up and commissioning of the Jiangqiao waste-to-energy facility, the largest in China, which has a treatment capacity of 1,500 metric tons/day with 24 MW of renewable energy. And now, we are the joint owner and operator of the facility. We also operate the Likeng waste-to-energy plant near Guangzhou, which has a capacity of 1,000 metric tons/day of municipal waste and generates 21 MW of electricity.

Stringent emission control

All of our sites are closely monitored and comply with current standards. Atthe Selchp site in the United Kingdom, we have reduced nitrogen oxide emissions and modernized the facility’s flue gas treatment system. In France, we conduct semi-continuous dioxin testing at all the sites where we are in charge of capital investments. At the Vaux-Le-Pénil site, waste is stored in a closed depot to minimize odors and dust, and water and flue gases are treated. At the Dunkirk site, meanwhile, the waste-to-energy plant for municipal waste will shortly be equipped with a wet flue gas treatment system and the Von Roll Inova process.

Plants that blend into their surroundings

We pay a great deal of attention to the architectural design of our treatment units and always make a concerted effort to ensure they blend into their surroundings. Two sites that deserve a special mention are the Marchwood site in the United Kingdom, and the waste-to-energy plant near Nîmes, which boasts an innovative design and an extremely efficient flue gas treatment system whose average emissions are 75% below the regulatory thresholds. Special care was also taken to ensure that our treatment units in the French towns of Vaux le Pénil and Valène blended into the surrounding area well.
