화장지의 표백 기준: ECF와 TCF 비교 설명

What is the difference between ECF and TCF?

ECF uses chlorine dioxide, reducing pollution but not eliminating it. TCF avoids chlorine entirely, offering better environmental performance but at higher cost.

Why Traditional Chlorine Bleaching is Problematic

Traditional chlorine bleaching methods, while inexpensive and effective, have significant environmental drawbacks. Bleaching pulp with chlorine produces toxic compounds known as chlorinated organic compounds (AOX), including dioxins. These chemicals are hazardous pollutants, contaminating water and harming ecosystems.

Recognizing these environmental issues, the paper industry has shifted towards cleaner, safer bleaching alternatives.

Understanding ECF & TCF Standards

The American Forest and Paper Association (AFPA) defines two main bleaching standards that you might see indicated on toilet paper products:

♦ Elemental Chlorine Free (ECF)

ECF pulp bleaching uses chlorine dioxide (ClO₂) instead of elemental chlorine. Although this significantly reduces the production of toxic AOX compounds compared to traditional chlorine bleaching, a small amount of elemental chlorine may still be produced during the process. Consequently, ECF bleaching isn’t entirely chlorine-free.

Environmental impact:

• Reduced dioxin and AOX emissions compared to traditional chlorine bleaching.
• AOX level typically ≤ 0.5 kg per tonne of pulp.

♦ Totally Chlorine Free (TCF)

TCF bleaching completely avoids chlorine-based compounds. Instead, it utilizes safer alternatives such as hydrogen peroxide (H₂O₂), ozone, or peracetic acid for pulp bleaching. The result is an entirely chlorine-free and environmentally cleaner process.

Environmental impact:

• Completely eliminates the release of dioxins and AOX pollutants.
• AOX level is zero, resulting in minimal environmental impact.

ECF vs. TCF: Which is Better for the Environment?

While environmental organizations typically favor TCF bleaching for its zero chlorine usage, there are ongoing discussions regarding which method is superior environmentally:

• Environmental groups’ viewpoint: TCF bleaching is superior due to its complete elimination of chlorine and resultant pollutants.
• Industry research: Numerous studies conclude TCF has clear environmental advantages. However, proper wastewater treatment practices are also essential to reduce environmental impact.

In short, both bleaching methods are improvements over traditional chlorine bleaching. Ultimately, proper wastewater treatment by responsible suppliers significantly influences environmental outcomes.
