Switchable degradation of cellulose acetate composite by seawater-activated TiO2 photocatalyst

Ji Hwan Lee et al.

Summary: Billions of tons of plastic waste are discarded in marine environments, and it is crucial to remediate plastic waste for ensuring a clean ocean. In this study, a seawater-activated photocatalyst was used to degrade cellulose acetate, and the successful preparation of the composite was confirmed through various analyses. The seawater-activated degradation of polymer-photocatalyst composites provides an efficient and eco-friendly solution for plastic waste remediation in marine environments.

Degradation of Cellulose Acetate in Simulated Aqueous Environments: One-Year Study

Nisha Yadav et al.

Summary: Cellulose acetate undergoes weight loss in aqueous environments due to deacetylation. The initial months of a 12-month study showed significant weight loss, with temperature having minimal effect. The degree of substitution (DS) is a crucial factor in the biodegradation of cellulose acetate, with lower DS resulting in higher degradation rates.

Triggering the Biodegradability and Green-Reuse of Cigarette Filters by a Facile and Home-Operating Treatment

Rumeng Xu et al.

Summary: Cellulose acetate (CA) is a commercially used material with excellent properties, but it is nonbiodegradable due to its hydrophobicity and poor adhesion to microbes. This study demonstrates a simple and mild treatment method to trigger the biodegradability and green-reuse of CA materials, by immersing them into common salt aqueous solutions. The treated CA materials showed improved hydrophilicity and adhesion to microbes, leading to rapid degradation in composting and soil burial tests. The method has great potential in environmental protection and ecofriendly utilization of biomass resources.

Angelique F. Greene et al.

Summary: A simple and environmentally friendly approach using 3D printing techniques for thermoplastic processing of rapidly degradable plastic-enzyme composites is described. The composites showed different degradation rates depending on the amount of AL loading, with AL capable of withstanding high in situ processing temperatures. Degradation rates of the composites in phosphate buffer were found to be faster compared to externally applied AL.

Carbon Dot-Triggered Photocatalytic Degradation of Cellulose Acetate

Nisha Yadav et al.

Summary: Chemical modification of biopolymers can reduce their degradation susceptibility, with carbon dots acting as green photocatalytic triggers for degrading cellulose acetate in open environments. The addition of carbon dots catalyzes the deacetylation reaction, leading to significant weight loss, release of small molecules, and regeneration of cellulose fibers. These results show promise for developing products with environmentally degradable processes triggered by photocatalysis, such as mulching films.

Near-complete depolymerization of polyesters with nano-dispersed enzymes

Christopher Delre et al.

Summary: By dispersing enzymes with deep active sites, semi-crystalline polyesters can be efficiently degraded in a short period of time, with up to 98% conversion of polyester to small molecules. This method allows for complete elimination of the need to separate and landfill products in compost facilities, with degradation achieved in standard soil composts and household tap water.

Lipase Immobilization in Mesoporous Silica Nanoparticles for Biofuel Production

Aniello Costantini et al.

Summary: Lipases are essential enzymes involved in the hydrolysis of triacylglycerol into fatty acids and have versatile applications, including biodiesel production. To maintain their stability and activity, lipases need to be immobilized on insoluble supports, with mesoporous silica nanoparticles being a promising option due to their thermal and mechanical stability, controlled textural characteristics, and surface functionalization capabilities.
