TCF (Totally chlorine-free)

Bleaching paper with elemental chlorine causes harmful AOX emissions in the aquatic environment. That is whyall our papers are ECF products as a minimum standard meaning they are !leached without elementary chlorine.The company"s volume of AOX lies within the BAT #Best Availa!le Technique$ range. This means technically andeconomically feasi!le environmental technology that is efficient and advanced and designed to reduce emissions

and the impact on the environment as a whole.%A&T'(&)* +eFresh T+'OTEC with TCF fi!res in the outer layers and ,- recycled fi!res in the inner layerand B'O TO/ ,* are our TCF #totally chlorine free$ products which are !leached without the use of any chlorine.'nstead they are whitened using o0ygen and hydrogen pero0ide. 

Understanding the differences between ECF, TCF and PCF bleaching

ECF #elemental chlorine free$ 1 ECF !leaching is a !leaching sequence without the use of elemental chlorine. 'nECF !leaching chlorine dio0ide is usually the main !leaching agent. Chlorine dio0ide has the highest selectivityamong technical !leaching chemicals. To minimi2e the environmental impact of the !leaching process the ECFprocess is usually com!ined with !leaching stages involving o0ygen hot acid or o2one.TCF #totally chlorine free$ 1 TCF !leaching is carried out without any chemicals containing chlorine there!yavoiding the generation of organically3!ound chlorine in the pulp and waste water stream. 'n TCF !leachinghydrogen pero0ide together with o2one or peracetic acid are the most commonly used chemicals. O2one isgenerated !y means of energy intense silent electrical discharges in a stream of o0ygen gas.PCF #process chlorine free$ 1 A !leaching process which entirely e0cludes the use of chlorine and chlorinedio0ide. %evertheless paper collected for recycling which forms the !asis of %A&T'(&)* for e0ample maycontain traces of chlorine su!stances. All recycled papers are produced using /CF. 

Which is better – TCF vs ECF!

Overall it is accepted that TCF and ECF discharges cannot !e separated on environmental grounds. 't is nowpossi!le to demonstrate that the discharges to watercourses from !oth ECF and TCF are of no environmentalconcern.+egarding the pulp itself the ECF process has the advantage of a significantly higher ratio of finished fi!re towood. This is due to the fact that TCF !leaching is done with o2one which is more corrosive chemical thanchlorine dio0ide.4ondi offers TCF ECF and /CF products in its portfolio in order to respond to our customers" needs andpreferences and we ac5nowledge !oth the advantages #2ero AOX emissions$ and disadvantages of TCF #lower

Totally chlorine free #TCF$ is a technique that uses no chlorine compounds for the !leaching of wood

pulp for paper production. This prevents the formation of dio0ins highly carcinogenic pollutants.

Elemental chlorine free #ECF$ is a technique that uses chlorine compounds rather than chlorine gas.
