ClearEnzymatic Degradation and Pilot-Scale Composting of Cellulose-Based Films with Different Chemical Structures
Researchers investigated the enzymatic degradability and pilot-scale composting of 14 cellulose-based materials including regenerated cellulose, cellulose acetate, methyl cellulose, and cellophane, finding that hydrolysis rate decreased exponentially as the degree of chemical substitution increased. The study establishes structure-biodegradability relationships to guide development of cellulose-based plastic alternatives that balance mechanical strength with natural biodegradability.

Controlling the rheology of cellulose dissolved in 4–methylmorpholine N–oxide and tensile properties of precipitated cellulose films via mixture design
This paper is not directly about microplastics; it investigates how blending cellulose pulps of different molecular weights affects the viscosity and mechanical properties of regenerated cellulose films, with applications in fiber and film manufacturing. While regenerated cellulose fibers have been discussed in the microplastics literature, this study focuses on industrial processing rather than environmental pollution.
Reassembly of wood to plastic- and paper-like films via ultra-mild dissolution in formic acid
Lignocellulosic biomass was converted into plastic- and paper-like films by dissolving wood in formic acid without ball milling or catalysts, then reassembling the formylated cell wall components by casting. The ultra-mild process offers a simpler route to renewable bio-based film materials from wood.

Revealing pore size distribution in cellulose and lignin-cellulose man-made fibers – effect of draw ratio and lignin content
Researchers measured the pore structure of cellulose and lignin-cellulose fibers using thermoporometry (a technique that uses freezing point changes to detect tiny pores) and found that drying the fibers causes partial, irreversible pore collapse that changes their internal architecture. The findings have implications for designing cellulose-based materials — a biodegradable alternative to synthetic plastics — where controlling pore structure determines performance.
