“…Although industry played a major role in the evolution of the modern human lifestyle it is being blamed for growing environmental concerns. In 2014, bioplastics represented only 0.2% of the global polymer market . Shifting society's dependence on fossil carbon sources towards renewable biomass resources is generally viewed as an important contribution to the development of a sustainable industrial society and the effective management of greenhouse gas emissions .…”

The replacement of fossil carbon with biomass is currently crucial for ecological, environmental, and economic reasons. Although the use of biomass-derived eco-friendly products is appealing to the public and to industry, research is slow to meet the demand for it. This may be due to lack of awareness and cooperation among different sectors of science and stakeholders. This paper takes a holistic perspective. It discusses the importance of agro-waste as a biomass resource and provides suggestions for its effective utilization to make economical and eco-friendly products. Taking an interdisciplinary approach, it discusses the opportunities for direct, economical, and environmentally friendly research fields such as the modification of plant structure, increasing biomass yield, and conversion of agro-waste to materials and chemicals. It suggests how these various fields can benefit industry and the public, and also discusses the importance of dialogue between the different stakeholders to accelerate growth in innovation, implementation, and development.

In order to toughen Poly(lactic) acid and binary blends with low PBAT content while maintaining a high biodegradability of the final material, poly(lactic) acid (PLA)/poly(butylene-adipate-co-terephthalate) (PBAT)/ polyolefin elastomer grafted with glycidyl methacrylate (POE-g-GMA) extruded ternary blends have been investigated in this work from a thermal, mechanical, and rheological point of view. The two elastomers have been added in different amounts as dispersed phases into the PLA matrix, paying attention to the final objective: the design of a 90% biodegradable formulation according to EN 13432. These ternary blends exhibited improved impact properties but still low elongation at break. Consequently, to the ternary composition with the best compromise of PLA quantity, biodegradability and thermo-mechanical properties (81 wt.% PLA, 9 wt.% PBAT, and 10 wt.% POE-g-GMA) a small quantity (10 wt.%) of a biobased plasticizer was added in order to further increase the impact properties in parallel with the tensile flexibility. Two types of plasticizers were investigated, one not reactive [Acetyl Tributyl Citrate (ATBC)], and one reactive [Glycidyl ether (EJ-400)]. A micromechanical study, in order to investigate the toughening mechanism of these systems, was carried out on the final formulations. They were also examined by dilatometric tests and elastoplastic fracture mechanics correlating the data obtained to the morphology and to the rheological properties. In conclusion, the best compromise between impact, tensile properties and biodegradability content was achieved using the reactive plasticizer (EJ-400) whose interaction with the matrix is confirmed by the FT-IR analysis.

The circular economy policy and the interest for sustainable material are inducing a constant expansion of the bio-composites market. The opportunity of using natural fibers in bio-based and biodegradable polymeric matrices, derived from industrial and/or agricultural waste, represents a stimulating challenge in the replacement of traditional composites based on fossil sources. The coupling of bioplastics with natural fibers in order to lower costs and promote degradability is one of the primary objectives of research, above all in the packaging and agricultural sectors where large amounts of non-recyclable plastics are generated, inducing a serious problem for plastic disposal and potential accumulation in the environment. Among biopolymers, poly(lactic acid) (PLA) is one of the most used compostable, bio-based polymeric matrices, since it exhibits process ability and mechanical properties compatible with a wide range of applications. In this study, two types of cellulosic fibers were processed with PLA in order to obtain bio-composites with different percentages of microfibers (5%, 10%, 20%). The mechanical properties were evaluated (tensile and impact test), and analytical models were applied in order to estimate the adhesion between matrix and fibers and to predict the material’s stiffness. Understanding these properties is of particular importance in order to be able to tune and project the final characteristics of bio-composites.
