At the current stage of science and technology development, production biodegradable polymers (BPs) polymeric materials (BPMs) for general industrial, agricultural, or household applications has become highly relevant. These retain their properties throughout service life and, upon its completion, gain ability to decompose under influence natural factors, integrating into metabolic processes biosystem. This review analyzes scientific technical literature from past decade on materials. The classification is provided based type degradation: capable complete mineralization, such as (cellulose, starch); synthetic prone biological degradation (polyesters, polyamides); subject erosion, blends polymers. types BPs are summarized according origin raw methods synthesis. serves foundation series articles dedicated first part focuses BPMs derived naturally renewable sources - that integral living plant animal organisms. Emphasis placed polysaccharides proteins. Among polysaccharides, provides a detailed examination cellulose derivatives (ethers, acetates, nanocellulose); starch (including thermoplastic chitin derivative chitosan; pectins; alginic acids. proteins, animal-derived proteins collagen gelatin, well plant-derived protein soybean discussed. For each these substances, molecular structure, physicochemical properties, production, fields application, mechanisms in nature presented. Using an example, strategy creating cellulose-containing proposed correlation between structure derivatives. 98 publications, concluding offer environmentally safer alternative traditional plastics made petroleum petrochemicals.

ABSTRACT This study aimed to compare the changes in composition of exopolysaccharide (EPS) produced by Lelliottia amnigena culture medium containing distilled water (DW) and dialyzed (DPW) irradiated either Laser (λ660 nm, 8.0 J/cm 2 ) or LED (λ630 12.0 during bacterial growth using Raman spectroscopy at 1064 nm. The cultures L. were 9‐ 12‐h, EPS obtained from different production protocols analyzed dehydrated. spectra showed peaks assigned saccharides polymer, principal component analysis revealed differences depending on used light source for irradiation. Remarkably, presence acyl groups (acetyl pyruvyl) mannose residues group DW without evidence acetyl groups; also presented carboxylate (succinyl).

The effect of sequential mixing poly(butylene adipate-co-terephthalate) (PBAT) and poly(lactic acid) (PLA) with organically modified silicate layers on the dispersion organoclay particles its morphology blended polymer clay nanocomposite (BPCN) was examined. platelets, blend composite, rheological thermomechanical properties these composites 50/50 ratio PLA to PBAT were investigated using X-Ray diffraction analysis, scanning transmission electron microscopy, dynamic mechanical shear test, thermogravimetric analysis. blends 70/30 also examined compared. this BPCN enhanced level when compared simultaneously nanocomposites. Larger domains better in phase observed first mixed then subsequently PBAT.

The design of more sustainable and eco-friendly solutions is one the central challenges in formulation today's laundry products. Water-soluble polymers are indispensable additives detergents as they play a wide range functions. At present, vast majority these still produced from petrochemical resources. In order to explore alternatives, this work, we have synthesized, characterized, tested novel group anti-redeposition soil release based on hydrophobically modified 2, 3-dihydroxypropyl chitosan (DHPCH), highly water-soluble derivative. Chitosan was selected basis its environmental profile. Our results suggest that hydrophobic moieties essential observe cleaning benefits synthetic based-textile. level modifications molecular weight unmodified were also shown be decisive conveying observable properties. This work significant because it illustrates DHPCH valid biorenewable platform for development new detergents.

The development of fully renewable and biodegradable composites for short-term applications was pursued by combining a compatibilized poly(lactic acid) (PLA)/poly(butylene succinate-co-adipate) (PBSA) (60:40 wt:wt) blend with coffee silver skin (CSS), an industrial byproduct from processing. An epoxy-based reactive agent (Joncryl ADR-4468) added as compatibilizer. CSS incorporated at 5, 10, 20 wt% in the both as-received state after simple thermal treatment boiling water, which performed to mitigate negative impact this filler on rheological mechanical properties blend. effectively increased degradation temperature 30–40 °C, enabling stable melt processing composites. It also improved filler–matrix adhesion, resulting enhanced (up +172% increase energy compared untreated filler). Therefore, treated demonstrated potential effective green reinforcement PLA/PBSA blends rigid packaging applications. Future works will focus studying suitable surface modification further interfacial interaction tensile quasi-static properties, exploit capabilities material toward eco-friendly
