Bioplastics are produced in growing amounts due to their environmental benefits, but their disposal routes remain ambiguous. A hydrothermal treatment (HT) may be a sustainable process to improve the fate of waste bioplastics, but nearly no information is available on how they respond to it. In this work, HT of biodegradable bioplastics was performed, and the resulting solid and liquid products were characterized by elemental analysis, analytical pyrolysis-based techniques, ion chromatography, and gas chromatography coupled with mass spectrometry. We selected tableware based on polylactic acid (PLA), cellulose, and Mater-Bi (MB) and performed HT at 160−200 °C. MB was identified as a mixture of PLA and polybutylene succinate (PBS). Higher treatment temperatures enhanced the solubilization, which was very marked for PLA and MB and minor for cellulose. Characterization of the solid residues revealed that PLA and MB were quantitatively degraded at 180 °C and above, while cellulose could never be fully degraded. The analysis of the aqueous phases from the HT of PLA and MB revealed the presence of an array of oligomers of PLA and PBS at low temperatures and of the corresponding monomers (lactic acid and succinic acid) at high temperatures: their recovery could represent a way to give new life to waste bioplastics.

“…De et al (2021) reported that the average biodegradability of lignocellulosic biorefinery, coconut fiber, and nanocrystalline cellulose was 52.6% after 15 days of soil burial; and this value is proportional to the weight of bioplastics. According to Bracciale et al (2024), biodegradation and disintegration of material were mainly influenced by the chemical composition of the material.…”

The aim of this study was to obtain the optimum concentration of phosphate butyrylated arenga starches (PBAS) of bioplastic based on the physicochemical and sensory properties. The PBAS was obtained by dual modification of native arenga starch through butyrylation using 5% butyric anhydride and crosslinking using 6% a mixture of sodium trimetaphosphate (STMP) and sodium tripolyphosphate (STPP) at 99:1 (w/w). The concentration of the PBAS tested varied at 4.7; 5.0; 5.3; 5.7; 6.0; 6.3; 6.7; 7.0; and 7.3% (w/v) with three replications so that there were 27 experimental units used. The thickness, water holding capacity (WHC), oil holding capacity (OHC), swelling power, solubility, water vapor transmission rate (WVTR), water content, pH, biodegradation and properties of sensory were investigated. Results showed that the thickness, solubility, WVTR and water content of bioplastics increased with the increase in the concentrations of PBAS. On the other hand, WHC and OHC, swelling power, pH, and biodegradation decreased along with the increase in PBAS concentrations. Sensory color of bioplastics increased, while texture, aroma and overall acceptability decreased with the increase in PBAS concentrations. The concentration of PBAS at 7.0% was optimum for the physicochemical and sensory properties of bioplastics as indicated by low WVTR and water content as well as panelist preference on bioplastic texture. Keywords: Phosphate butyrylated arenga starches; Physicochemical of bioplastic; Sensory of bioplastic.

“…Biodegradable plastics are currently replacing commodity plastics in various applications, such as disposable tableware, especially after Europe adopted some measures for the phasing out of traditional plastic tableware [1]. One of the most common blends on the market is Mater-Bi® (MB), a family of polymeric compounds usually based on thermoplastic starch (TPS) and commercialized with different chemical formulations depending on the used co-polymer [2]. The main advantage of bioplastics is the possibility to treat them along with the organic fraction of municipal solid waste (OFMSW) in the existing composting or anaerobic digestion facilities [3].…”

An innovative approach based on hyperspectral imaging (HSI) was developed to monitor commercial starch-based (MaterBi®) disposable bioplastic behavior during anaerobic degradation. Mater-Bi® (MB) tableware items were selected among the ones available in supermarkets and compliant with the EN 13432 standard (EN 13432:2008). The MB items were manually cut in fragments with size ranging from 0.5 to 2 cm, removing the edges and the bottom to ensure test material homogeneity in terms of thickness. The anaerobic sludge was collected at a full-scale mesophilic anaerobic digestion plant treating a mixture of organic residues from food industries and was used as inoculum. Hyperspectral images of the samples composed of MB fragments dispersed in the anaerobic sludge were acquired in the short-wave infrared range (SWIR: 1000-2500 nm). A chemometric approach was then developed to analyze HSI data. In more detail, Principal Component Analysis (PCA) was applied for data exploration, followed by the implementation of a classification model based on Partial Least Square-Discriminant Analysis (PLS-DA) able to identify MB in the sludge. The achieved results are very promising, especially with reference to the possibility to adopt a fast strategy to monitor the behavior of MB during the anaerobic biodegradation process.
