200422235 V. Description of the invention (1) <Technical field to which the invention belongs> The present invention relates to a biodegradable container and a manufacturing method thereof, particularly a natural material mainly composed of plant materials and supplemented by mineral materials. Physical and chemical methods are processed and die-casted to obtain low-cost, pollution-free, naturally decomposable containers. <Hepatitis transformation in the first district is convenient and common. ) The rate-up of the box made the country ’s pre-polybenzene technology. According to the Asian region is the region where hepatitis is prevalent in the world, so Asian countries are very active in preventing the occurrence of hepatitis, and Taiwan originally proposed to use it for prevention. Disposable tableware policy. With the development of the economy, after the industrialized society, such disposable tableware or containers, because of their high sex, make it impossible for modern people to replace them. At present, disposable containers on the market are mainly made of polystyrene, plastic, or paper (Po1ystyrene, PS). They are made of petroleum-based foaming trays, instant noodle bowls, and thinner oils. The chemical formula is (C8H8) n. See the residue, the current US regulation is 5 0 0 PPM, I will release suspected carcinogenic properties, which may increase the liver load. Polystyrene foam currently used is polystyrene. After the agent is heated, the foaming is different from ten to twenty times. It can be made into disposable tableware, raw containers and industrial packaging supplies. Polystyrene is a plastic raw material composed of carbon and gas. Polystyrene is a polystyrene container. The most common residual limit of styrene in Polytron tableware is 100 ppm. Polychloride is not resistant to acid and heat. It has a hepatotoxicity in ethylene and other organic substances in South Vancouver.

Page 4 200422235 V. Description of Invention (2). Therefore, Polyuron tableware food or oily food is wrapped to avoid causing polystyrene residue. Polyuron tableware is filled with hot food and because the annual output of Polyuron materials is about 91,000 tons, the foundation's recycling treatment system furnace . In the absence of sunlight, Polyrons cannot be buried for decades. Even if the Polylons are fully burned in the temperature, they will burn completely, which will release black smoke and irritating gas. Therefore, in addition to the polystyrene and membrane in Polyron, it can not be decomposed in the body, such as inhibiting the central nervous system and causing damage to the body. It also causes the dark red color made by other than Polyron containers). Plastic food, when consumed, will still produce food and hot soup, liver cancer, lethargy and other diseases. Dioxins are also manufactured in assimilation furnaces. It is safe to put them in food containers for safe use. It is still very common. In a large number of 45-year-old garbage that flows into the air, it causes serious field treatment, which requires carbon dioxide and <Dioxin>. Ying Sheng Baolong will ensure that there are about a hundred cases. The rest, water, decomposes, turns into incineration and turns into sex gas. It will soften and deform when exposed to high heat. Foaming agent Ding Shui will irritate arrhythmia, headache, and it is not easy to recycle. For environmental pollution, containers are also used in the market. However, when this kind of raw polyvinyl chloride and other toxic chemicals such as toxic are used up, they are discarded and placed in a microwave oven with a Baidu Baidu temperature of more than one hundred degrees. However, At present, the people use it, and Polyron enters the Baoguang landfill or incineration landfill, even if it is white pollution. High water above 70 ° C. Otherwise, it will burn in the open air1, severely pollute the air, and in the long term, the eyes and respiratory tract will become tired and liver and kidney functions will be regenerated, which will cause problems in the landfill. Polyethylene (PVC containers containing thermochemicals that are slightly soluble and infiltrate the council will cause the plastic material to be discarded in the human body.

At present, polyethylene (PE) plastic bento boxes and food commerce unions "have tens of thousands of paper bento boxes, &gt; grow into trees <about one each. So Taipei only. When a lot of trees are cut down, when Taiwan rains heavily, it becomes a severe global temperature or random discharge of waste water. The cultivation of crops and paper containers with bacteria or wet hair is not easy to remove. This makes it easy for the EPA to remove, dispose of, and to sum up, the convenience of Polyron containers has caused a lot of people ’s use and environmental pollution. Therefore, the government has actively announced the use of Polyron containers. And because of the environmental and other problems of plastics and polystyrene containers, paper containers used for paper containers or tableware are gradually made of a layer of adhesive film or wax coated with virgin pulp. They are widely used in disposable trays. , Beverage paper cups, trays. According to "Taipei Food Report, the average daily consumption of the Greater Taipei area is 100, and only 1 million bento boxes need to be cut down 3 4 5 pieces: 8 meters high, 16 cm in diameter, 2 0 -40 Seniors> Paper bentons need to be cut down more than 250 hectares of forest trees a year, which will cause soil loosening and ground loss. For this reason, problems such as soil and rock flows are common, and the room effect is invisible. In addition, the papermaking process If the waste water is not prepared well, it will also cause water and marine pollution, so that the soil has no marine resources. In addition to the above-mentioned defects, in order to prevent the virgin pulp from becoming moldy, the paper container (PE) will be used in the manufacture of paper containers. Or polypropylene (PP) film, but this kind of decomposition, so the paper container after use is not easy to return on August 17, 1982 announced such paper products as "the long-term non-perishable ingredients in general Waste. " Disposable containers currently on the market have the following disadvantages:

Page 6 200422235 V. Description of the invention (4) 1. Polyurethane and plastic containers begin to soften heat-resistant food at 95 ° C. 2.
