“…However, lignin is hydrophobic and presents crosslinking ability and adhesive nature, which enhance the dispersion of fibers that enable stress transfer. [180] The degree of dispersibility of cellulose fibers is dependent on the processing conditions. It can be increased with the decrease of fiber length.…”

The amount of residues generated by agriculture, industrial, or urban activities continuously increases and, consequently, demands several methods for their correct management. The incorrect disposal can cause, in specific cases, environmental contamination by heavy metals or leaching as well as promote the spread of diseases as insect proliferation. Commonly, landfilling, incinerating, composting, or energy/fuel generation can control the disposal or reuse of residues. Among the methods for the reuse of wastes, the incorporation of residues as fillers in polymer composites has emerged as a distinct field. Some composites can potentially mitigate leaching compounds or improve mechanical, thermal, and acoustic properties. However, these improvements are a challenge to promote the use of waste fillers. Thus, this study aims to provide a state of view regarding a variety of wastes used as fillers in polymer composites and different methods to reach mechanical reinforcement as well as improve thermal conductivity and acoustic attenuation for future researches.

Nanoparticles have been used to improve the properties of oilfield polymers however, at higher and prolonged temperature, dihydroxylation of the bonds occurs decreasing the affinity of the oilfield polymers towards the surface of the nanoparticles. Hence, polymeric nanoparticles (LPNP) with rigid structures have been sought after to circumvent this problem. Therefore, in this study, LPNP was synthesized from sago palm (Metroxylon sagu) bark and used as a rheological agent to improve the viscosity of displacement fluids. Thereafter, the synthesized LPNP was characterized via transmission electron microscopy, particle size analysis, zeta potential, Fourier transform infrared spectroscopy and thermogravimetric analysis. Then, the rheological flow behaviour of lignin polymeric nanofluid (LPNF) was investigated at low and high shear rates utilizing a 350 RST Brookfield rheometer. Box-Behnken design was used to simulate the effect of salinity, shear rate, concentration, and temperature on the viscosity of LPNF. Statistical analysis of variance was used to analyse various parameters of the model. Finally, any parameter combination that resulted in the maximum viscosity was recorded and optimized using a multi-response surface model. The synthesis method was efficacious in producing LPNP with a size range of 10–23 nm. Besides, LPNF exhibited shear thinning and pseudoplastic behaviours even at high salinity and showed good stability up to a temperature of 170°C. The predicted viscosity with a regression coefficient (R2) of 0.8 indicates that the experimental data were accounted for by the model. The desirability of 0.95, which is close to unity, indicates that statistical analysis and experimental evidence have demonstrated that LPNF has acceptable flow behaviour under reservoir conditions.
