TM System Finland Oy has developed SuperDryer™, a breakthrough drying system for pulp, fibre (

The piloting process for bringing SuperDryer to the market is supported by European Innovation Council.
Current drying methods poorly recover the evaporated water and its heat, and generally can have significant particle emissions. SuperDryer is designed to be able to run with renewable energy and it replaces old, dirty, expensive and energy consuming technologies. SuperDryer reduces the huge amount of emissions that occur during the drying process. It recovers 100% of heat and evaporated moisture during the drying process, while simultaneously capturing the airborne particle emissions, odour, CO2, and visible vapour fume from the exhaust air. In the drying process, the system creates controlled circumstances in a closed operation of air circulation, and captures emissions such as dust particles, CO2, VOC's, and the evaporated water from the exhaust air, before recirculating the air back to the process.
SuperDryer is compact and scalable to many industries and to many production sizes. It is applicable for instance in paper, board and pulp industries, mechanical wood, food, feed and beverage, textile and fibre, Bio2X, fertilizers, mining and metal industries, as well as in power plants and sludge and waste treatment.
To indicate the scale and significance of SuperDryer's impacts, we take an example from pulp and paper industry. By adopting SuperDryer for sludge and side stream drying, an average size pulp or paper mill would save up to €5 million on energy costs and 20 million litres of water annually. By switching from landfill to drying of industrial waste and side stream effluents, a mill can cease the emission of landfill gases, 40-60% of which is methane with the remainder being mostly carbon dioxide. By switching from traditional fossil fuel powered pulp dryers to SuperDryer, an average size pulp mill could cut CO2 emissions by 42,000 tonnes yearly.
