In this study, we developed a pathway to valorize sugarcane bagasse left from sugar production to food-related end products through pulp molding, which represents a sustainable material and clean manufacturing. The sugarcane bagasse from the sugar industry is naturally safe for food-related applications. The produced tableware is fully biodegradable, renewable, and environmentally friendly. We also developed a hybrid fiber strategy that long bamboo fibers were blended with short sugarcane fibers, which formed abundant physical interwinding in the obtained tableware with superior performances as required for food containers, including high tensile strength, superior oil stability, excellent hydrophobicity, and low heavy metal content. Of note, our tableware was mostly biodegraded under natural conditions within 60 days, which is largely shorter than the degradation time for synthetic plastics. Moreover, in comparison with polystyrene production, pulp molding produced much less CO₂ emission. The tableware made from biomass thus represents an eco-friendly, low cost, and biodegradable alternative to synthetic plastics for food packaging.

在这项研究中，我们开发了一种途径，以通过制浆成型来增值从制糖业到与食品相关的最终产品的甘蔗渣的价值，这是一种可持续的材料和清洁生产。制糖业的甘蔗渣自然对食品相关应用是安全的。所生产的餐具是完全可生物降解的，可再生的且对环境友好的。我们还开发了一种混合纤维策略，即将长竹纤维与短甘蔗纤维混合，在获得的餐具中形成丰富的物理缠绕，具有食品容器所需的优越性能，包括高拉伸强度，优异的油稳定性，优异的疏水性和低重金属含量。值得注意的是，我们的餐具大多在自然条件下于60天内被生物降解，这大大短于合成塑料的降解时间。此外，与聚苯乙烯生产相比，纸浆模塑生产的二氧化碳要少得多₂发射。因此，由生物质制成的餐具代表了食品包装用合成塑料的环保，低成本和可生物降解的替代品。
