“…The TGA analysis also revealed the presence of a starch-based material, as stated by the producer [8], since there is about a 5% mass loss at low temperatures (lower than 100 • C), as shown in Figure 14b [40]. by the producer [8], since there is about a 5% mass loss at low temperatures (lower than 100 °C), as shown in Figure 14b [40]. The presence of two phases in the neat polymeric matrix of Solanyl ® C1201 was further corroborated by SEM images which, at ×500, clearly shows the presence of both phases.…”

Study of the Properties of a Biodegradable Polymer Filled with Different Wood Flour Particles

Lignocellulosic wood flour particles with three different sizes were used to reinforce Solanyl® type bioplastic in three compositions (10, 20, and 30 wt.%) and further processed by melt-extrusion and injection molding to simulate industrial conditions. The wood flour particles were morphologically and granulometric analyzed to evaluate their use as reinforcing filler. The Fuller method on wood flour particles was successfully applied and the obtained results were subsequently corroborated by the mechanical characterization. The rheological studies allowed observing how the viscosity was affected by the addition of wood flour and to recover information about the processing conditions of the biocomposites. Results suggest that all particles can be employed in extrusion processes (shear rate less than 1000 s−1). However, under injection molding conditions, biocomposites with high percentages of wood flour or excessively large particles may cause an increase in defective injected-parts due to obstruction of the gate in the mold. From a processing point of view and based on the biocomposites performance, the best combination resulted in Solanyl® type biopolymer reinforced with wood flour particles loaded up to 20 wt.% of small and medium particles size. The obtained biocomposites are of interest for injected molding parts for several industrial applications.

“…The addition of TPS decreased the thermal stability of the PCL/TPS and PLA/TPS blends. On the other hand, the increase in TPS content in PLA/PCL blends (in-ternary system) deteriorated the mechanical properties, which was explained by low compatibility [ 233 ]. Some studies were performed to evaluate the performance of blends of PBS with two different types of TPS, EGTPS (plasticized with glycol), and GTPS (plasticized with glycerol), in different compositions for potential packaging applications [ 234 ].…”

Review of the Most Important Methods of Improving the Processing Properties of Starch toward Non-Food Applications

Starch is the second most abundantly available natural polymer in the world, after cellulose. If we add its biodegradability and non-toxicity to the natural environment, it becomes a raw material very attractive for the food and non-food industries. However, in the latter case, mainly due to the high hydrophilicity of starch, it is necessary to carry out many more or less complex operations and processes. One of the fastest growing industries in the last decade is the processing of biodegradable materials for packaging purposes. This is mainly due to awareness of producers and consumers about the dangers of unlimited production and the use of non-degradable petroleum polymers. Therefore, in the present review, an attempt was made to show the possibilities and limitations of using starch as a packaging material. The most important physicochemical features of this biopolymer are discussed, and special attention is paid to more or less environmentally friendly methods of improving its processing properties.

“…[ 121 ] TPS blends with biodegradable polymers for example, poly(vinyl alcohol), poly(lactic acid), poly(ε‐caprolactone) and poly(3‐hydroxybutyrate) are completely biodegradable. [ 122 ] In case of TPS blends with non‐biodegradable polymers, the TPS component biodegrades in a meaningful timeframe. It is important to note that reinforced 100% renewable TPS blends are generally obtained by including natural fibers like wood pulp, hemp and other plant fibers.…”

Plastics are excellent materials owing to their multipurpose uses. They are simple synthetic macromolecules with versatile properties. On the disposal front, nearly 90% of the plastic products are discarded only after a single use, which keeps accumulating, impacting both terrestrial and marine life. About 6.3 billion tonnes of plastic waste have accumulated worldwide from the time of the plastic revolution. Around 79% of plastic waste amasses in landfills every year, and 2.41 million tonnes of the waste enters oceans. The accumulation of this waste poses harmful threats to the environment and flora and fauna of land and aquatic habitats. To keep a check on the generation and collection of plastic waste, the utilization of alternative materials developed from biodegradable polymers as substitutes to plastics seems quite sound. The present perspective highlights single use plastic's (SUP) challenges and the importance of biodegradable polymers as possible substitutes to SUPs. The scope of different biodegradable polymers and their suitability for developing alternative materials to SUPs is discussed. In addition, the current market status of alternative materials produced from biodegradable polymers is described. Finally, a perspective on the future of biodegradable polymers as substitutes to plastics for envisaging a green world is outlined.
