“…The chemical changes include the chain scission or the incorporation of new chemical groups. Degradation of plastic depends on several factors such as: temperature changes, electromagnetic radiation [11], moisture [12] and biological activity [13]. Anaerobic digestion of organic compounds is an efficient way of their waste disposal combined with the energy recovery.…”

Polymer composites with natural fibers prepared by melt blending were investigated. Synthetic and natural macromolecules were used, including poly(lactic acid), polyhydroxybutyrate-co-polyhydroxyvalerate and low density polyethylene. These polymers were filled with flax fibers. Mechanical properties of the composites, biogas production and mass loss under anaerobic digestion have been presented. It has been shown that the mechanical properties sustain after 28 days of biodegradation. Such materials can be found in applications as packaging, as well as in medicine as polymeric scaffolds, and drug delivery systems etc.

As alternatives to petroleum-based polymeric materials, biodegradable polymers, such as polycaprolactone has attracted a lot of attention in the scientific community due to a rapid growth of intensive interest in the global environment. Chalcone, hexadecylamine and tetradecylamine were used as one of the organic compounds to modify natural montmorillonite clay. The clay modification was carried out by stirring the clay particles in an aqueous solution of chalcone-montmorillonite, hexadecylamine-montmorillonite and tetradecylamine-montmorillonite increasing from 1.29 to 1.53, 1.59 and 1.79 nm, respectively. The modified clay was then used in the preparation of the polycaprolactone/epoxidized palm oil blend nanocomposites. They were prepared by incorporating 0.5-5% of chalcone-montmorillonite, hexadecylamine-montmorillonite and tetradecylaminemontmorillonite. The interaction of the modifier in the clay layer was characterized by X-ray diffraction and transmission electron microscopy. The nanocomposites were synthesized by solution casting of the modified clay and a polycaprolactone/epoxidized palm oil blend at the weight ratio of 80/20, which had the highest increase in the tensile strength of the blend. The X-ray diffraction and transmission electron microscopy results confirmed the production of nanocomposites. The results also showed higher thermal stability for nanocomposites compared to those of the polycaprolactone/ epoxidized palm oil blend.

“…There is an increase in demand for using biodegradable polymers in packaging applications as the use of biodegradable polymers symbolizes a step to protect from environmental pollution. 27 Cho et al 28 investigated the biodegradation of PCLstarch blend and PBS under aerobic and anaerobic conditions. They found that PCL-starch based polymer was easily degraded at higher biodegradation rates (88%) than PBS blends (31%) under similar periodic conditions.…”

Polybutylene/starch/nanoclay composite blends were prepared by melt extrusion technique. Maleic anhydride grafted polybutylene was used as a compatibilizer. The nanocomposites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, atomic force microscopy, rheological, and mechanical analysis. Addition of compatibilizer to the polybutylene/starch/nanoclay showed dispersion and nucleation related to the nanoclay in the polybutylene matrix. An increase in the mechanical properties like modulus and tensile strength at break and a decrease in the elongation at break were observed on the addition of compatibilizer to the matrix compared to that of uncompatibilized matrix. The biodegradability of the nanocomposites was studied using the landfill burial test. The blends subjected to the burial test were evaluated for their tensile properties. The results revealed that the tensile strength and elongation at break of the compatibilized nanocomposites decreased after 80 days of land burial test compared to the initial period.
