    Description
    Title of the invention: BIODEGRADABLE DRINKING STRAW [0001] BACKGROUND
    Technical Field [0002] The present invention relates to drinking straws, and, more particularly, a biodegradable drinking straw which contributes to the protection of the environment.
    Description of the Related Art [0004] At present, commercially available drinking straws can be divided into three types by material, namely plastic, glass and stainless steel.
    Most of the existing plastic drinking straws are made of a material extracted from petroleum. When used to consume drinks at high temperatures, such a plastic drinking straw can release toxic components such as a plasticizer. Plastic drinking straws are also suspected of becoming a source of toxicity when exposed to and eroded by acidic beverages. In particular, organic fruit juice bars where most drinks contain abundant fruit acids are more vulnerable to the potential toxicity of plastic drinking straws.
    Glass drinking straws are made of silica (SiO 2 ) and other auxiliary components mixed in different proportions by different processes depending on their end applications. During their manufacture, glass drinking straws are formed at a temperature as high as 1600 ° C, then baked in an annealing oven. However, the high fragility means that drinking straws in glass tend to break accidentally and lead to loss of production.
    [0007] Stainless steel drinking straws are made with high energy consumption. Three of the four ovens used in the manufacturing process must be heated to around 1500 ° C. Although some modern factories have their own co-generation systems and / or waste heat recovery systems, there is still a considerable amount of waste gas and waste heat emitted to the environment. The fact that steel requires an enormous amount of energy to carry out a transformation means that such a product inevitably requires high environmental costs.
    From a manufacturing point of view, both glass drinking straws and stainless steel drinking straws consume a huge amount of energy from the input of the material to production. This energy consumption exploits natural resources terribly and exacerbates the greenhouse effect. In addition, plastic drinking straws can contain a large amount of plasticizer, which can be dissolved by and enter beverages at high temperature or containing esters. The human body may have difficulty breaking down or excreting the plasticizer it ingests. Like other plastic products, drinking straws containing a plasticizer, when in long-term contact with children, can induce early puberty and sterility and increase the risk of asthma and allergies, raising health and safety concerns.
    [0009] Consequently, the manner of treating the problems and defects mentioned above observed in the prior art is a question which arises for the inventor of the present invention and for persons in the industries concerned.
    SUMMARY OF THE INVENTION The objective of the present invention is to provide a biodegradable drinking straw mainly made of a powder of vegetable fiber powder and of a polymer, which eliminates the use of traditional plastics in the manufacture of straws and can be rapidly biodegraded in nature, thus making it possible to minimize the resulting impact on the environment and to maintain environmental protection.
