“…Due to their mechanical strength and intermolecular interactions, composites and mixed materials are stronger than the TS matrix alone. However, TS seems to be less vulnerable to soil microorganisms [ 51 , 52 , 53 ]. These results demonstrate that the degradation rates of the TSP-3.0 and TSP-5.0 were greatly affected by the addition of fn-POSS [ 54 ].…”

Rapid advancements in materials that offer the appropriate mechanical strength, barrier, and antimicrobial activity for food packaging are still confronted with significant challenges. In this study, a modest, environmentally friendly method was used to synthesize functionalized octakis(3-chloropropyl)octasilsesquioxane [fn-POSS] nanofiller. Composite films compared to the neat thermoplastic starch (TS) film, show improved thermal and mechanical properties. Tensile strength results improved from 7.8 MPa to 28.1 MPa (TS + 5.0 wt.% fn-POSS) with fn-POSS loading (neat TS). The barrier characteristics of TS/fn-POSS composites were increased by fn-POSS by offering penetrant molecules with a twisting pathway. Also, the rates of O2 and H2O transmission were decreased by 50.0 cc/m2/day and 48.1 g/m2/day in TS/fn-POSS composites. Based on an examination of its antimicrobial activity, the fn-POSS blended TS (TSP-5.0) film exhibits a favorable zone of inhibition against the bacterial pathogenic Staphylococcus aureus and Escherichia coli. The TS/fn-POSS (TSP-5.0) film lost 78.4% of its weight after 28 days in natural soil. New plastic materials used for packaging, especially food packaging, are typically not biodegradable, so the TS composite with 5.0 wt.% fn-POSS is therefore of definite interest. The incorporation of fn-POSS with TS composites can improve their characteristics, boost the use of nanoparticles in food packaging, and promote studies on biodegradable composites.

The circular economy (CE) has gained global attention for its potential to promote sustainable production and consumption through continuous growth and the efficient use of resources. Despite several reports highlighting its benefits, there is still a lack of concrete and proven studies examining the importance of institutional pressures for the transition towards CE in food supply chains. This study aims to address this gap by conducting a Systematic Literature Review (SLR) to identify the drivers and barriers to the institutionalisation of CE in food supply chains, and to propose practical and managerial implications for achieving this transition through institutional pressure. We reviewed 25 studies and conducted a descriptive analysis of papers per year and journal, followed by a categorical thematic analysis. The results indicate that normative pressures were the most frequently identified among the different institutional pressures, followed by mimetic and coercive pressures. Therefore, promoting CE in food supply chains may require the implementation of laws, policies, and strict governance to reduce risks. This paper contributes to the existing literature and provides valuable insights for researchers and practitioners interested in the transition towards a CE in food supply chains.

“…As the most abundant organic waste on earth, food waste includes household, food processing, canteen, and restaurant waste, which mainly contains carbohydrates such as starch and sugar, proteins and lipids. With this composition, food waste had great potential for biogas production using the AD system and the benefits of organic waste reduction ( Cohn et al, 2022 ; Onyeaka et al, 2022 ; Qian et al, 2022 ). On the other hand, Napier grass, which is classified as lignocellulosic biomass, has cellulose, hemicellulose, and lignin as its main organic components.…”

The co-digestion of untreated Napier grass (NG) and industrial hydrolyzed food waste (FW) was carried out in the batch reactor to investigate the effect of substrate ratios on biogas production performance. Two-stage anaerobic digestion was performed with an initial substrate concentration of 5 g VSadded/L and a Food to Microorganism Ratio (F/M) of 0.84. The 1:1 ratio of the NG and FW showed the optimum performances on biogas production yield with a value of 1,161.33 mL/g VSadded after 60 days of digestion. This was followed by the data on methane yield and concentration were 614.37 mL/g VSadded and 67.29%, respectively. The results were similar to the simulation results using a modified Gompertz model, which had a higher potential methane production and maximum production rate, as well as a shorter lag phase and a coefficient of determination of 0.9945. These findings indicated that the co-digestion of Napier grass and hydrolyzed food waste can enhance biogas production in two-stage anaerobic digestion.
