The reasons for using biodegradable particles in disposable environmentally friendly tableware are as follows:

环保理念：可降解颗粒是以天然植物淀粉、纤维素等为原料制成的，相对于传统的塑料材料更加环保。使用可降解颗粒可以降低对环境的影响，减少塑料垃圾的产生和对土壤、水源等资源的污染。

Environmental protection concept: Biodegradable particles are made from natural plant starch, cellulose, and other raw materials, which are more environmentally friendly compared to traditional plastic materials. The use of biodegradable particles can reduce the impact on the environment, reduce the generation of plastic waste, and pollute resources such as soil and water sources.

可降解性：可降解颗粒在自然环境中会发生生物降解过程，通过微生物的作用可分解为二氧化碳和水等无害物质，不对环境造成持久性污染。相比之下，传统塑料制品需要数十年甚上百年才能降解，大量塑料垃圾积累会给环境带来严重问题。

Biodegradability: Biodegradable particles undergo a biodegradation process in the natural environment, which can be decomposed into harmless substances such as carbon dioxide and water through the action of microorganisms, without causing persistent pollution to the environment. In contrast, traditional plastic products take decades or even hundreds of years to degrade, and the accumulation of a large amount of plastic waste can cause serious environmental problems.

卫生：可降解颗粒通常符合食品级标准，在接触食品时不会释放有害物质，且不易滋生细菌。相比之下，一些常见的塑料餐具可能含有对人体健康有潜在风险的化学物质，因此使用可降解颗粒制成的餐具更利于食品。

Safety and hygiene: Biodegradable particles usually meet food grade safety standards, do not release harmful substances when in contact with food, and are not prone to bacterial growth. In contrast, some common plastic tableware may contain chemicals that pose potential risks to human health, so using tableware made of biodegradable particles is more conducive to food safety.

可替代性：可降解颗粒可以与传统塑料颗粒进行混合使用，生产一次性环保餐具具有与传统材料相似的性能和外观。这意味着生产工艺上可以更容易地实现转变，不需要更换现有的生产设备，节约生产成本并推动环保产品的普及和应用。

Replaceability: Biodegradable particles can be mixed with traditional plastic particles to produce disposable environmentally friendly tableware with similar performance and appearance to traditional materials. This means that the production process can be more easily transformed, without the need to replace existing production equipment, saving production costs, and promoting the popularization and application of environmentally friendly products.

总的来说，使用可降解颗粒制作一次性环保餐具是为了实现对环境的保护，减少塑料垃圾污染，并确保食品和卫生。

Overall, the use of biodegradable particles to make disposable environmentally friendly tableware is aimed at protecting the environment, reducing plastic waste pollution, and ensuring food safety and hygiene.
