“…The cellulose content is related to the oxygen proportion and is associated with the resistance degree of the fiber. In this sense, lignocellulosic materials with a higher oxygen content or a higher value in the O/C ratio will have a better mechanical performance [54][55][56][57]. CHF presented a higher cellulose content On the other hand, CHF and CCF fibers addition generate slight improvements (1 and 8%) on the flexural strength (FS) compared to neat r-PP.…”

In this work, biocomposites based on recycled polypropylene (r-PP) and two different natural fibers (coffee husk-CHF and coconut coir-CCF fibers) were prepared using extrusion and injection molding processes. Also, the addition of maleated polypropylene (MAPP) as a coupling agent on the biocomposites was explored. Recycled polypropylene and its biocomposites were tested following ASTM standards in order to evaluate tensile and flexural mechanical properties. Also, thermal behavior and the morphology of these materials have been studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and scanning electronic microscopy (SEM). The experimental results showed that the addition of CHF and CCF to the r-PP resulted in an increase in the flexural modulus and thermal properties of the composites but resulted in poor impact properties. Thermal characterization showed that CHF possesses a better thermal stability compared to CCF. However, both fibers act as nucleating agents and generate an increase in the thermal stability of the r-PP phase. Finally, it was observed that addition of 4% of MAPP significantly improved the mechanical strength and impact behavior of the biocomposites. Regarding environmental issues, a cradle to gate life cycle assessment was made in order to define the carbon footprint of the materials.

In a world seeking environmentally sustainable products, bio-resources are investigated as suitable replacements to oil-derived products. Tannin extracts represent one of the most abundant phenolic resources of the earth, with more than 200,000 T/year. These extractives are constituted mainly of polyphenolic compounds and they are used industrially for various purposes, including leather tanning, wine-making, and water clarification. However, condensed tannin extractives can also be easily polymerized, and the resulting bio-macromolecule can be exploited for other applications such as adhesives and coatings. In recent years, tannin-based polymers have also been used for the synthesis of fire-resistant insulation foams and outdoor wood preservatives. This bio-resource imparts also outstanding water resistance to wood plastic composites (WPCs) and gives great antioxidant activity to nanofibrillated cellulose films, which become an interesting material for "active packaging". This literature review covers these four innovative solutions made from tannin extractives from mimosa or black wattle (Acacia mearnsii) industrial powder and provides some basic information about the purification of the industrial tannin extract that can be suitable for more chemically specific usages.

“…Właściwości mechaniczne włókien naturalnych, takich jak: konopie, sizal, juta, len, mączka drzewna uzasadniają ich stosowanie w charakterze napełniaczy tworzyw termoplastycznych. Ich właściwe związanie z łańcuchami polimeru próbuje się osiągnąć w wyniku doboru rodzaju i ilości kompatybilizatora, a także obróbki fizycznej bądź chemicznej [10,[17][18][19][20]. Najbardziej zaawansowane technicznie zastosowania takiego napełniacza są możliwe przy użyciu wyselekcjonowanych włókien roślinnych, co bez wątpienia rzutuje na koszty procesowe.…”

Artykuł stanowi wieloaspektową analizę celowości i możliwości zastępowania kompozytów tworzyw termoplastycznych z napełniaczami mineralnymi kompozytami zawierającymi włókna roślinne. Analizę przeprowadzono w odniesieniu do kompozytów polipropylenu, szeroko stosowanych i dobrze scharakteryzowanych pod względem właściwości użytkowych. Wykazano, że entuzjastyczne oczekiwania związane z możliwością wykorzystania termoplastów napełnionych włóknami roślinnymi z szeroko dostępnego odnawialnego surowca, jako tanich materiałów o atrakcyjnych właściwościach, nie są w pełni uzasadnione. Realnym rozwiązaniem jest natomiast otrzymywanie takich kompozytów do niezbyt wyrafinowanych zastosowań z odpadowych poliolefin i odnawialnego materiału włóknistego, pochodzącego z odpadów przemysłu rolnego i leśnego.
