Moulded pulp fibers for disposable food packaging: A state-of-the-art review

Carbon Neutral Lifestyles and NDCs: Advice and Policy Perspectives

“…Therefore, giving advice to opt for second-hand clothes, or making people understand how ecosustainable fabrics are preferred to non-renewable ones (such as nylon, polyester, and acrylic), can lead to a reduction in emissions in the sector. Likewise, creating greater awareness of the benefits of recycled packaging such as moulded pulp -that comes from wood, bamboo, bagasse, or wheat straw-or "greener" oxo-degradable plastics can contribute to reduced demand on landfills and a drop in pollution (Katherine E. Semple, 2022). This is also valid for electronic devices, which are often thrown away instead of being repaired: extending their useful life by opting for "repair instead of replacement" would have a lower environmental impact.…”

Electrostatically Complexed Natural Polysaccharides as Aqueous Barrier Coatings for Sustainable and Recyclable Fiber-Based Packaging

“…Fossil-derived plastics have been widely adopted in the packaging industry due to their low cost, easy processability, light weight, and desired mechanical and barrier properties . However, most of these plastics are nonbiodegradable, and their production, use, and end-of-life profile show an open-loop life cycle; as a result, they end up in landfills or the natural environment, which will accumulate up to 12 billion metric tons by 2050, causing severe environmental impacts and ecosystem threats. , To tackle this global challenge and align with UN sustainable development goals, the packaging industry is transitioning to renewable, recyclable, and eco-friendly fiber-based packaging solutions, especially in the food and beverage packaging sectors. , However, cellulosic fiber-based materials (e.g., paper, paperboard, and molded pulp) are porous, hygroscopic, and thus susceptible to the permeation of various liquids (e.g., water, oil, and grease) and gases (e.g., moisture, oxygen, and aroma), significantly compromising their barrier performance, which are vital to extending the shelf life and improving the safety and quality of packaged goods. To address the barrier functionality gaps between traditional holistic fossil plastic-based and fiber-based packaging, various barrier technologies have been implemented, including lamination, metallization, extrusion coatings, and polymer dispersion or solution coatings. , However, nonrenewable, nonbiodegradable materials (e.g., synthetic polymer latexes, metals/metal oxides) and the multilayer structural design commonly employed in these technologies adversely impact the recyclability of fiber-based packaging …”

Press-forming molded pulp from repulped liquid packaging board: Role of heat input, pressing force, and defect formation

“…The increased thickness in molded pulp products is connected to improved modulus under bending and tensile modulus (Curling et al 2017). The thickness of the molded pulp products is important in manufacturing thin-walled items (Semple et al 2022), and geometrical accuracy of thermoformed molded pulp products is influenced by their pulp type (Didone and Tosello 2018).…”
