How Much Do You Know About The Environmentally Friendly Wheat Straw Tableware That Is Now Popular?

Starch is the second largest natural polymer on the earth after cellulose, it is abundant, renewable and inexpensive, and can be used to produce starch-based plastics through modified plasticization. As an important category of bio-based materials, starch-based plastics have successfully achieved industrial production and application. Starch-based plastic is a kind of plastic product made of starch as the main raw material, modified and plasticized and then blended with other polymers, which is a kind of bioplastic. Starch-based bioplastics can be divided into two categories: bio-based plastics and biodegradable plastics.

Starch-based biodegradable plastics are generally a blend of modified starch and biodegradable polyester, which can be fully biodegradable, compostable, no pollution to the environment, and waste is suitable for composting, landfill and other treatment methods. Starch-based bio-based plastics are generally a mixture of modified starch and polyolefins (such as PP/PE/PS, etc.), and its environmental significance is that it can reduce the use of petrochemical resources, reduce carbon dioxide emissions, and waste is suitable for incineration. Both materials can replace traditional petroleum-based plastics and are widely used in plastic packaging materials, shockproof materials, plastic films and plastic bags, disposable tableware, food containers, toys, etc.

Recently, a wheat straw tableware that claims to be absolutely environmentally friendly, absolutely safe, and absolutely non-toxic has become popular on Internet communication channels. Merchants have repeatedly emphasized and displayed its characteristics: “suitable for children, safe, non-toxic and healthy”. These characteristics have undoubtedly attracted a lot of attention, and many people believe that straw meals can one day replace plastic tableware and reduce the harm of non-degradable materials to the environment.
