Controlling Hazards Release of Biomass‐Based Melamine Composite Tableware‐Based on the Synergistic Effect of Corn Starch and Bamboo Fiber

With the enhancement of environmental concerns, tableware made with renewable resources are in high demand. However, it is found that for biomass‐based melamine tableware (CMFs), there is a risk of accelerating the release of melamine and formaldehyde, leading to potential hazards when in contact with hot food and beverages. This study aims to use a combination of two biomasses to fabricate melamine tableware with eligible hazards. The results show that the ether bondings in CMFs increase the risk of formaldehyde and melamine adsorption and the release during use, while these release values can be regulated by the ratio of corn powder and bamboo fiber. When ratio of corn powder and bamboo fiber reaches 1:1, the CMFs demonstrate minimized surface tension (40.07 mN m −1 ), intact microstructures, and porosity is 3.45%. The release of formaldehyde reaches 5.62 mg kg −1 , and the release of melamine is 0.55 mg kg −1 , eligible for standard GB 4806.6‐2016. This study provides design guidelines for sustainable yet safe melamine tableware for industrial application.
