One-step valorization of cellulose acetate plastic waste into 5-hydroxymethylfurfural<\/strong><\/p>\n

Recently, Dr. Chunxiao Gong (Associate Professor), together with Prof. Shuai Li (Fujian Agriculture and Forestry University) and Dr Qixuan Lin (South China University of Technology) proposed a one-step method to convert cellulose acetate (CA) plastic waste into the high-value chemical 5-hydroxymethylfurfural (HMF). The research, titled \u201cOne-step valorization of cellulose acetate plastic waste into 5-hydroxymethylfurfural\u201d, was published in Applied Catalysis B: Environment and Energy (IF:21.1). Dr. Chunxiao Gong is the first author, while Profs. Zhen Fang, Shuai Li and Dr Qixuan Lin are the corresponding authors.<\/p>\n

Cellulose acetate (CA) is a widely used cellulose derivative, commonly applied in cigarette filters, textiles, and plastics. The extensive use of CA-based products generates large amounts of plastic waste. Due to its low biodegradability, CA has become a \u201chidden source of pollution,\u201d persisting in the environment for more than 10 years, with degradation rates decreasing sharply as the degree of acetylation increases. This poses severe environmental challenges.<\/p>\n

In this study, using AlCl3<\/sub> as the sole catalyst in an acetone\u2013water solvent system at 160 \u00b0C for 50 minutes, CA was converted into HMF with a yield of 53.7%, which is three times that of untreated cellulose. When real waste materials (cigarette filters and CA fabrics) were used as feedstocks, the HMF yield also exceeded 50%. This technique provides a feasible route for the upcycling of CA plastic waste.<\/p>\n

The in-situ generated acetic acid synergistically interacted with AlCl3<\/sub>, where acetic acid coordinated with Al(III) to regulate Lewis acidity, suppressing side reactions and promoting the fructose dehydration pathway. Meanwhile, the acetyl groups in the CA structure enhanced interactions with acetone solvent, further improving reaction selectivity. The process was equally effective for real CA waste (e.g., cigarette filters, fabrics), demonstrating strong application potential. Compared to previous studies on cellulose conversion to HMF, this system achieved high efficiency under milder conditions and with lower catalyst loading, offering a new pathway for the valorization of CA plastic waste.<\/p>\n

Molecular dynamics simulations revealed that CA\u2019s acetyl groups form noncovalent interactions with acetone molecules. Acetone preferentially surrounds the C1 and C4 positions of CA, preventing unnecessary protonation at these sites and thereby reducing byproduct formation (e.g., humins). The interaction energy (\u0394E) between a CA monomer and acetone reached 15.04 kcal\/mol, while that between a cellulose disaccharide monomer and acetone was only 7.76 kcal\/mol, showing a significant difference. During the reaction, acetic acid released from deacetylation further participated in catalysis, working synergistically with AlCl3<\/sub> to promote HMF formation.<\/p>\n
