Biodegradable plastics refers to a type of plastic that is degraded by the action of microorganisms in nature, such as bacteria, molds (fungi) and algae. The ideal biodegradable plastic is a kind of polymer material with excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and finally inorganicized to become a component of the carbon cycle in nature. "Paper" is a typical biodegradable material, while "synthetic plastic" is a typical polymer material. Therefore, biodegradable plastics are polymer materials with both "paper" and "synthetic plastics" properties.
1. BSR fully degradable resin can be completely degraded 100%, and the degradation time is short.
2. The temperature resistance can reach 102-115 degrees, which greatly improves the usability of biodegradable materials.
3. Significant cost reduction: plant fiber has a wide range of sources, and the cost can compete with traditional plastics. It is currently the lowest cost fully biodegradable material on the market.
4. Improved physical properties: The physical properties of plant fibers are brought into BSR materials, making some BSR materials even better than traditional plastics, such as film products with higher strength, injection molding materials and sheet materials with better temperature resistance, etc.
5. Good processing and forming: small shrinkage, non-sticky, good toughness, high strength, good dimensional stability, not easy to embrittlement.
6. Material density reduction: It is the characteristic of the BSR material itself, the density of some products is lower than that of traditional plastics, thereby further reducing the cost of the product.
will not.
International standards have a unified and scientific definition of "biodegradation": it can be completely decomposed by molds secreted by microorganisms in nature in a certain temperature and humidity environment. In other words, under normal storage conditions (no material or product provided with high temperature, high humidity and microbial environment), it will not disappear by itself.
BSR Will not produce toxic substances and cause secondary pollution to the environment.
EN13432, ISO14855, ASTM6400 and other international biodegradation testing and experimental method standards have strict tests on whether the decomposed materials will cause secondary pollution to the environment.
It is not recommended to use in a microwave oven.
The correct statement should be: under normal storage and transportation environment, the shelf life of BSR products ranges from 6-12 months (depending on the product type); when the product is discarded, under the conditions of composting domestic waste (temperature, Humidity and mold quantity reach a certain standard), complete biodegradation in 2-6 months.
This interpretation is incomplete. Compostable is also called composting. Refers to the biochemical process of using microorganisms that are widespread in nature to control the conversion of degradable organic matter in solid waste into stable humus.
Composting is a process of producing organic fertilizer. It contains rich nutrients and has a long and stable fertilizer effect. It also promotes the formation of soil solid structure, and can increase the soil's ability to retain water, heat, air, and fertilizer. Mixed use can make up for the shortcomings of the single nutrient contained in chemical fertilizers. Long-term single use of chemical fertilizers will harden the soil and reduce water and fertilizer retention performance. Composting is the use of various organic wastes (such as crop straw, weeds, leaves, peat, organic household waste, food waste, sludge, human and animal manure, distiller’s grains, fungus chaff, and other wastes) as the main raw materials, and decomposed into organic fertilizer.
Compost: Refers to a specific environment. For example, domestic waste composting refers to “composting with representative microbial populations and their concentrations contained in the sludge formed by municipal waste over the years under a specific temperature and humidity environment”.
Burying: refers to burying certain materials in the natural environment. It is not scientific (reproducible) and standardized (how deep is it buried? Is it buried in the desert or in the woods? Junkyard?).
The cost/price of fully biodegradable materials around the world is much higher than that of similar ordinary plastics, generally 3-4 times. BSR is the biodegradable material with the lowest cost and the most cost-effective among many completely biodegradable materials.
Neither BSR nor other biodegradable materials belong to any of the recycling category, but belong to the category of "biodegradable materials".
Yes, it will. Any mixed waste is difficult to sort or detect simply because of the different properties of various materials. Therefore, the finished product of biodegradable materials can be discarded as general garbage, and do not enter the recycling system.
BSR does not have special property to resist acid and alkali.
Certain thick products (such as toothbrushes, mugs, toys,etc.) can of course be used repeatedly until the end of the product life cycle; some products are not suitable for repeated use (such as used garbage bags, greasy lunch boxes, etc.).
Yes, it will decompose by themselves, in accordance with international standards: the weight loss rate of products exceeds 90% within 180 days.
