Tana aims to increase use of tyre derived fuelPublished 16/9, 2019 at 14:59
Finnish company Tana avowed aim is to increase the usage of alternative fuels in the cement and lime industry. Through the use of its waste shredder, cement manufacturers can produce alternative fuel of the required particle size in one pass.
Due to rapid urbanisation, there is an increasing need for cement especially in developing economies in Asia, South America and Africa. The future lies in the use of sustainable solutions, such as alternative fuels, including tyre derived fuel (TDF), which is an environmentally friendly and cost efficient replacement for materials such as oil and coal that have traditionally been used in cement kilns.
The energy consumption of cement kilns is one of the largest expenditures in cement production. If it can be optimised by switching to alternative fuels, there is a direct effect on cement producers’ bottom line. Using TDF reduces fuel costs as the heat value of tyre shred is almost equal to oil, and 25% better than that of coal. Additionally, TDF decreases the NOx emissions produced by cement plants, and makes cement producers less affected by changes in the price of oil.
Tana is a Finnish ‘clean tech’ forerunner that aims to increase the usage of alternative fuels in the cement and lime industry. With Tana’s waste shredder, cement manufacturers can produce alternative fuel of the required particle size in one pass. The Tana ‘Shark’ shredder can turn difficult material such as end of life tyres into alternative fuel. The consistent quality of the tyre derived fuel results in high quality clinker. Moreover, it gives better control over the CO2 and NOx emissions in the form of more efficient incineration. Compared to RDF, there is less variability in TDF which makes the burning process easier to manage.
“Using only alternative fuels in cement production is the future. There are already examples in the market where fossil fuels have been substituted by (up to) 85% with alternative fuels coming out of waste streams,” says Josef Imp, vice president, sales, Tana.
