Biopolymeric materials have increased their uses and applications in the past years since more advanced preparations have been implemented to find the best formulation for a particular application. Holocellulose from spent coffee grounds (HOLO‐SCG) is a unique material with scarcely studied peculiarities. A detailed study of the flow behavior, microscopy, thermal, and local mechanical properties needs to be performed on biopolymeric films to open the understanding of polymer responsiveness, which is essential for the final design of the composites when fitting characteristics on macroscopic and microscopic scales are achieved. This manuscript aims to obtain biopolymer blends and films based on chitosan (CS) and polyvinyl alcohol (PVA) and reinforced with micro HOLO‐SCG. It seeks to investigate their compatibility and physicochemical properties in liquid states by rheological measurements and solid states using physicochemical, thermal, and mechanical experiments. The results indicate that the prepared CS : PVA films reinforced with HOLO‐SCG under controlled size provide an excellent biopolymeric structure with enhanced thermal and mechanical properties, which brings a stable product to be used as an alternative plastic due to their noticeable lower wettability. The biopolymeric film could be introduced as a bio‐composite material in food packaging applications in further experiments.

The pollution caused by petroleum‐derived plastic materials has become a major environmental problem that has encouraged the development of new compostable and environmentally friendly materials for food packaging based on biomodified polymers with household residues. This study aims to design, synthesize, and characterize a biobased polymeric microstructure film from polyvinyl alcohol and chitosan reinforced with holocellulose from spent coffee grounds for food‐sustainable packaging. Chemical isolation with a chlorite‐based solution was performed to obtain the reinforced holocellulose from the spent coffee ground, and the solvent casting method was used to obtain the films to study. Physicochemical and microscopic characterizations were conducted to identify and select the best formulations using a simplex‐centroid design analysis. The response surface methodology results indicate that the new packaging material obtained with equal amounts of polymers and reinforced material (1:1:1) possesses the appropriate barrier properties and microstructural character to prevent water attack and hydrophobic behavior and thus could be used as an alternative for food packaging materials.

Nowadays, non‐timber sources are of greater interest as they avoid deforestation and the pollution which occurs with cellulose obtention. An emerging alternative is using weeds such as windmill grass (Chloris spp.) to isolate cellulose since the plant grows in large quantities near crops or landfills used for farming. The present study aims to explore windmill grass as an alternative source of cellulose for applications as reinforcement in biopolymeric matrices. Treatment was conducted using the peroxyformic pulping method, varying the formic acid (FA) and hydrogen peroxide (HP) concentration to obtain an optimum cellulose extraction condition. The isolated celluloses were analyzed for chemical composition, yield, chemical functionality, crystallinity, and morphology. The optimum pulping condition (FA = 87.5%, HP = 3%) shows the gradual removal of non‐cellulosic components by microscopy. X‐ray diffraction analysis revealed a high crystallinity index (89.63%) with a characteristic cellulose type I pattern. To evaluate the reinforced effect of Chloris spp. celluloses, film formulations were made using sweet potato starch, glycerol, and cellulose at different concentrations (2.5, 5.0, and 7.5% w/w). The films' mechanical, physicochemical, and thermal properties were measured, and results indicate that adding cellulose fibers significantly improves these properties of sweet potato starch films, revealing further applications and non‐wood windmill grass added value with potential applications in the packaging sector.Highlights Windmill grass (Chloris spp.) is presented as a non‐wood source of cellulose. The peroxyformic method is reported as a less polluting cellulose extraction process. Optimal cellulose pulp presents enhanced physicochemical properties after bleaching. Cellulose‐reinforced sweet potato starch films exhibit a stable biopolymeric matrix. The films produced show enhanced water barrier and mechanical/thermal properties.
