Disposable biodegradable tableware common in the market

Although disposable tableware is convenient, it will cause environmental pollution, and ordinary plastic tableware will also have adverse effects on human health. To replace these plastic cutlery, researchers around the world are looking for other solutions. One of the solutions is to develop biodegradable tableware. The following are currently common disposable biodegradable tableware.

Using sugarcane, reed and other plant fiber pulp as raw materials, after scientific and technological treatment, food-grade waterproof and oil-proof agent is used, which has the characteristics of environmental protection, sanitation, non-toxic and harmless, waterproof and oil-proof, no deformation and no leakage, and can be used for microwave oven baking. , Refrigerator frozen preservation, with recycling value.

This eco-friendly meal has the following features:

1. Resistant to 120°C hot oil and 100°C hot water, no water leakage or deformation for two hours.

2. Suitable for microwave oven baking, refrigerator freezing and fresh-keeping.

3. Clean, hygienic, non-toxic, harmless, healthy and safe.

4. It has recycling value, renewable paper, recyclable and resource protection.

5. Natural degradation returns to organic fertilizer and returns to nature (180 days for natural degradation).

Due to the edibility of sugarcane, sugarcane tableware has more significant external advantages than wood pulp, straw pulp, reed pulp and other raw materials in terms of material; When the finished product is finished, there is no need to add auxiliary agents due to molding problems, and the performance, decomposability and degradability of the product can be fully guaranteed.

corn polylactic acid disposable biodegradable tableware

corn flour polylactic acid

Lactic acid is produced by fermentation of corn starch, which is produced through a special polymerization process.

This eco-friendly meal has the following features:

1. The corn starch extract is extracted with high technology, does not contain any chemical toxins, and is highly safe for the human body.

2. Due to the excellent biocompatibility of corn polylactic acid, it is approved by the US FDA for medical surgical sutures, injection capsules, etc.

3. After testing, the tableware material (PLA) is weakly acidic and has plant antibacterial and bactericidal functions.

4. Pure natural biological manufacturing, degradable after disposal.

Corn plastic has the advantages of good biodegradability, good mechanical and physical properties, and good compatibility. However, compared with the readily available sugarcane pulp, the yield of corn PLA is still not high. Moreover, corn is also a staple food. The production of polylactic acid in large quantities will consume a large amount of corn, thereby increasing the price of food.

starch food disposable biodegradable tableware

Hard biscuit utensils made from starchy materials such as sorghum, rice and whole wheat flour, such as ready-to-eat spoons. Plates, chopsticks, etc., may be more in line with people's definition of edible tableware. The practice of edible tableware in this way is not difficult, only four steps: mixing - pouring - coal burning and forming - completion.

This eco-friendly meal has the following features:

1. You can eat it all after eating, it is delicious and fun, and it will be very popular with children.

2. A variety of products can be developed according to people's tastes: sugar, cinnamon, ginger, garlic, fennel, mint, ginger, carrot and other flavors.

3. Put it in the food for 10 to 15 minutes to soften, and put it in hot water for 20 minutes without soaking. If you don’t want to eat it after use, throw it away and I heard that it only takes 4 to 5 days to decompose naturally. Compared with the above two materials, the degradation rate is undoubtedly the fastest.
