A Clean Process for Obtaining High-Quality Cellulose Acetate from Cigarette Butts

Area of Science:

• Materials Science
• Environmental Science
• Chemical Engineering

Background:

• Cigarette butts (CBs) are a prevalent, non-biodegradable environmental pollutant.
• Cellulose acetate fibers in CBs degrade very slowly, posing environmental risks.
• Existing recycling methods for CBs are diverse but can be improved.

Purpose of the Study:

• To develop a novel, green, low-cost, and efficient method for extracting cellulose acetate (CA) from discarded cigarette butts (DCBs).
• To assess the feasibility of converting recycled CA into a widely consumed fashion product.

Main Methods:

• A two-step extraction process involving washing with water and ethanol.
• Purification and drying of extracted cellulose acetate fibers at 60 °C for 60 minutes.
• Characterization of the recovered CA properties for comparison with pure CA fiber.

Main Results:

• The developed method efficiently recovers cellulose acetate fibers from cigarette butts.
• The extracted and purified CA exhibits properties comparable to virgin CA fiber.
• Preliminary results indicate the suitability of recycled CA for fashion product manufacturing.

Conclusions:

• The proposed method offers a sustainable and economical approach to cigarette butt waste recycling.
• Recycled cellulose acetate from cigarette butts holds promise for producing fashion items, such as eyeglass frames.
• This research contributes to waste valorization and the circular economy.
