VYNCKE helps to reduce CO2 emissions in the GREEN ENERGY SULLY project
Sully-sur-Loire, France – MERIDIAM, DALKIA and SWISS KRONO France inaugurated their energy plant, as part of their GREEN ENERGY SULLY project. The most important goal of this project was to reduce CO2 emissions from the plant. Two new low-temperature dryer belts were installed, powered by a biomass waste energy plant. For the supply of this energy plant, DALKIA chose to work with VYNCKE, an international player in clean energy technology.
Facing a triple challenge
DALKIA was founded in 1937 as an energy service contractor under the EDF Group. With headquarters in Saint-André-lez-Lille, France, the company focuses its expertise towards boosting the use of renewable and local energy, and energy savings. DALKIA was enlisted by SWISS KRONO France, founded in 1988 as part of the SWISS KRONO Group, active in the wood-based materials sector. Together with MERIDIAM, a global investor specialized in developing, financing and managing long-term public infrastructure projects, they started the GREEN ENERGY SULLY Project.
The project was brought to life to address a triple challenge at the SWISS KRONO factory at Sully-sur-Loire: reducing dust & VOC emissions, reducing energy consumption, and, most importantly, the decarbonization of the factory. The project required a €120 million investment and took two years to complete.
SWISS KRONO France is the sole producer of Oriented Strand Board (OSB) panels in France. Manufacturing 1200m3 of panels on todays basis, the company felt stunted in its growth due to the inefficient high-temperature dryers it used for drying the OSB strands. Through the realization of this project, the company then also aimed to increase its production capacity.
The project was realized in two parallel stages. First, two low-temperature belt dryers were installed. These dryers replaced two high-temperature rotary drum dryers, making the plant 5-10% more energy efficient, all while reducing dust emissions and boosting productivity. Simultanuously, a biomass energy plant was put in place to power those dryers and aid in the factory’s processes. For this, DALKIA chose to work with VYNCKE, a Belgian company which had supplied them with biomass boilers numerous times in the past.
VYNCKE’s solution
VYNCKE supplied a turnkey 65 MW biomass energy system, tailor-made for energy supply to particle board, OSB and lamination production. The energy plant is equipped with a water-cooled stepgrate and combustion chamber and a flue gas condenser, resulting in energy production with an efficiency above 100%. The biomass waste burned in the fuel flexible boiler consists of bark, wood waste, sander dust and other wood residues from the SWISS KRONO wood panel production processes. The energy plant supplies 55 MW hot water to power two dryers, and 18 MW thermal oil, which is used for the presses. The maintenance and operation of the energy plant falls under the responsibility of DALKIA, which will deliver the produced energy to the SWISS KRONO factory.
Reduction in energy requirements and natural gas
Thanks to the GREEN ENERGY SULLY Project, SWISS KRONO France can boast a CO2 reduction of 35.000 tons per year (equivalent to 19.000 cars), a 5-10% reduction in energy requirements and an 80-95% reduction of natural gas.
