Abstract Paper made from natural fiber of ampel bamboo (Bambusa vulgaris) and nano-activated carbon from sawdust had been tested as food packaging and showed its ability to maintain freshness and nutritive value of foodstuffs. However, as a packaging material, natural degradability of this alternative natural-fiber paper is required to be tested. This study aims to determine the effect of nano-activated carbon on paper’s biodegradation properties. The results showed that paper treated with nano-activated carbon degraded faster in the soil compared to paper made of bamboo fiber only (control) after 8 weeks of observation. The microorganism population density analysis showed that the paper with nano-activated carbon had a lower microorganism density than the control which accompanied by a decrease in paper weight after 12 weeks of observation. This finding demonstrates the potential utilization of nano-activated carbon as an additive to be inserted into paper to accelerate the biodegradation rate of paper in the soil. The ability of paper to be degraded naturally is very important to support environmental sustainability.

Interesting Alternative

Recently, several types of food packaging have been developed which are able to prolong shelf-life of, and maintain the quality and safety of, products. Many kinds of material have been applied to food packaging, in the forms of film, sachets, or pads, to protect, eliminate, or inhibit undesirable changes in food. Based on the increasing concern about environmental sustainability, there have been many attempts to develop a natural biodegradable food packaging. Activated carbon as a multifunctional material is an interesting alternative choice. Apart from its ability to naturally degrade, non-toxicity, and low cost, it possesses remarkable adsorption potential. Its abilities are versatile, and could be used in various application purposes. Thus, its ability strongly depends on its pore structure and surface chemistry. Although it has been known for its effect on hydrophobic substances, the modification of pore size and surface property of activated carbon could improve its affinity to hydrophilic substances. Two means of activated carbon applications in food packaging were classified, according to its adsorption and releasing ability. The first mean is the application of activated carbon for the emission of antimicrobial agents in the vapor phase and nanoparticles inside food packaging. The second mean is the application of activated carbon for scavenging of factors affecting food quality inside packaging, such as water vapor, oxygen, ethylene, and odor. In this paper, the adsorption-releasing mechanism of activated carbon on some of the antimicrobial agents and vapor phase substances are discussed. Additionally, the potential role of activated carbon in food packaging is summarized.

Purpose of the paper: The paper aims to enrich the knowledge on the role of packaging material in influencing the product buying process. Methodology: A between-subjects experimental design was conducted in order to investigate if the product quality judgment and the purchase intention towards the product differ among different packaging materials. Findings: Glass is considered better than other materials, especially in terms of lower perceived risk and higher (a) product quality, (b) intention to buy and (c) willingness to pay. By contrast, plastic does not have a good image. Research limits: Since the perception of the material should be closely related to the product category, caution should be exercised in generalizing the findings to the all food categories. Practical implications: The study has useful insights for manufacturers and product managers in the packaging management, one of the relevant components of the marketing mix. Originality of the paper: Most of the evidence regarding packaging cues focuses principally on elements like colour, shape, graphics and nutritional claims. A limited marketing research has been conducted about the crucial role of the packaging material in the consumers’ evaluation process.

Natural renewable materials can play a big role in reducing the consumption of synthetic materials for environmental sustainability. Natural fiber-reinforced composites have attracted significant research and commercial importance due to their versatile characteristics and multi-dimensional applications. As the natural materials are easily rotten, flammable, and moisture absorbent, they require additional chemical modification for use in sustainable product development. In the present research, jute fibers were treated with rot-, fire-, and water-retardant chemicals and their corresponding polymer composites were fabricated using a compression molding technique. To identify the effects of the chemical treatments on the jute fiber and their polymeric composites, a Fourier transformed infrared radiation (FTIR) study was conducted and the results were analyzed. The presence of various chemicals in the post-treated fibers and the associated composites were identified through the FTIR analysis. The varying weight percentage of the chemicals used for treating the fibers affected the physio-mechanical properties of the fiber as well as their composites. From the FTIR analysis, it was concluded that crystallinity increased with the chemical concentration of the treatment which could be contributed to the improvement in their mechanical performance. This study provides valuable information for both academia and industry on the effect of various chemical treatments of the jute fiber for improved product development.

Specific Influence

The environmental problem generated by the massive consumption of plastics makes necessary the developing of biodegradable antimicrobial materials that can extend food shelf-life without having a negative impact on the environment. The current situation regarding the availability of biodegradable food packaging materials has been analysed, as well as different studies where antimicrobial compounds have been incorporated into the polymer matrix to control the growth of pathogenic or spoilage bacteria. Thus, the antimicrobial activity of active films based on different biodegradable polymers and antimicrobial compounds has been discussed. Likewise, relevant information on biodegradation studies carried out with different biopolymers in different environments (compost, soil, aquatic), and the effect of some antimicrobials on this behavior, are reviewed. In most of the studies, no relevant effect of the incorporated antimicrobials on the degradation of the polymer were observed, but some antimicrobials can delay the process. The changes in biodegradation pattern due to the presence of the antimicrobial are attributed to its influence on the microorganism population responsible for the process. More studies are required to know the specific influence of the antimicrobial compounds on the biodegradation behavior of polymers in different environments. No studies have been carried out or marine media to this end.

Lignocellulose Biomass

The current study stresses on the reuse of waste lignocellulose biomass (rice husk and sugarcane bagasse) for the synthesis of carboxymethyl cellulose (CMC) and further conversion of this CMC into a biodegradable film. Addition of commercial starch was done to form biodegradable film due to its capacity to form a continuous matrix. Plasticizers such as Glycerol and citric acid were used to provide flexibility and strength to the film. Biopolymer film obtained from sugarcane bagasse CMC showed maximum tensile strength and elongation in comparison to the film synthesized from commercial CMC and CMC obtained from rice husk. It has been observed that an increase in sodium glycolate/NaCl content in CMC imposed an adverse effect on tensile strength. Opacity, moisture content, and solubility of the film increased with a rise in the degree of substitution of CMC. Therefore, CMC obtained from sugarcane bagasse was better candidate in preparing biopolymer/biocomposite film.

Bamboo species are an alternative for the composition of forest plantations. However, their potential has not been explored due to the hard time in producing large-scale clonal plants. Thus, the aim this work was to evaluate the in vitro establishment, bud multiplication and ex vitro rooting of Bambusa vulgaris. The first experiment tested different systemic and contact fungicide solutions, based on exposure time, during the establishment phase. Established explants were subjected to evaluation of residual fungicide effect on subcultures during the multiplication and elongation phases. The second experiment evaluated the influence of activated carbon on ex vitro survival and on adventitious rooting. Explant immersion in liquid culture medium added with 1.0 mL of fungicide for 120 hours has favored the in vitro establishment and reduced fungal contamination. On the other hand, it favored the shoot emission of shoots per explant during the multiplication phase. Both rooting induction culture medium and mini-incubator system use were effective in enabling adventitious root formation. The presence of activated carbon in the rooting induction culture medium resulted in a higher clonal plant survival rate.
