Full biodegradable plastic innovation on the market!

It is understood that the EU produces 25 million tons of plastic waste every year, but only 1 / 10 of it is recycled. In order to solve the problem of a large number of plastics being discarded, the European Parliament has passed a bill to completely ban disposable plastic products. In fact, different countries or regions have similar bans. For example, South Australia and France have banned the sale of disposable straws, tableware and mixing rods since 2021; The Chinese mainland also banned the production and sale of disposable foam plastic tableware in 2021.

Among the first batch of "no plastic" lists, disposable bags containing non biodegradable polymer materials include shopping bags, daily plastic bags, paper plastic composite bags and garbage bags; Disposable tableware containing non biodegradable polymer materials, including boxes (including covers), bowls (including covers), dishes, plates, beverage cups (including covers) and other products, are listed in the "blacklist". In the supplementary catalogue of "plastic prohibition", there are ultra-thin agricultural film, disposable knives, forks and spoons, plastic cotton swabs and washing products containing plastic beads.
Facing the increasingly serious "plastic ban order", the market began to be filled with a variety of alternatives. Some of these substitutes boast that the materials are natural, some boast that they are all biodegradable plastics, and others are degradable plastics. What exactly does these boast represent? Is the so-called environmentally friendly plastic really environmentally friendly?
What is "fully biodegradable plastics"?
Under natural conditions or artificial control, organic substances can be decomposed and transformed into small molecular substances under the action of biological life activities.
Under natural conditions, affected by temperature, water, light, oxygen and other factors, it is different from biodegradable plastics. Fully biodegradable plastics do not contain biodegradable components, so they can be completely decomposed by microorganisms without residue, which is fully biodegradable plastics.
What is the difference between "fully biodegradable plastics" and "degradable plastics"?
Degradation is PE + degradation agent; Or add starch, stone powder, etc. Although it can be degraded, it can not be completely degraded. It still contains plastic and other related components. Only part of it can be degraded under natural conditions. If it is buried or burned, it will still cause harm to the environment and indirectly aggravate the greenhouse effect. That is, when people choose or use this degradable plastic, It will also pollute the environment like traditional plastic bags.
Fully degradable plastics refer to: under natural conditions, such as soil and / or sandy soil, and / or specific conditions, such as composting, anaerobic digestion or aqueous culture medium, they are degraded by the action of microorganisms existing in nature, such as bacteria, molds and algae, and finally completely degraded into carbon dioxide (CO2) or / and methane (CH4) Mineralized inorganic salts of water (H2O) and its elements and plastics of new biomass. Therefore, "degradable plastic" is only "degradable plastic" and is equal to "fully biodegradable plastic".
So "all biodegradable plastic" is the real environmental protection plastic!
It is understood that all biodegradable plastics have appeared in the market, including Junyi all biodegradable materials. It can complete all biodegradation in 1-6 months in the natural environment. It can also adjust the degradation period according to the demand, and there will be no pollution during the period.
What kinds of biodegradable plastics are there in China at present?
Fully biodegradable plastics: the leading product is PLA. Biodegradable plastics refer to biodegradable plastics based on natural polymers or polymers synthesized from natural monomers. At present, this kind of plastics mainly include polylactic acid (PLA) and polyhydroxyalkanoate (PHA).
What are the characteristics of all biodegradable plastics in the market?
This new type of fully biodegradable plastic has good ductility and heat resistance. It is widely used in agricultural film, packaging bags, fast food and other fields. According to incomplete statistics, China's takeout industry alone uses more than 60 million plastic lunch boxes every day, that is, more than 20 billion plastic lunch boxes and 1 billion instant noodle bowls are produced every year, Waste plastics account for about 7% of domestic waste. Amazing data bring a huge market to all biodegradable plastics. At present, Junyi biodegradable composite membrane material has completed the product demonstration production line and will enter the industrial market.
Its fully biodegradable packaging film has soft feel, strong tensile force, good sealing, good texture and environmental protection; The microorganism that can breed in the agricultural plastic film has the function of agricultural slow-release fertilizer, which can improve the soil temperature and maintain the soil moisture: the shopping bag and garbage bag film introduced to the market can be moderately waterproof, stable quality, high production efficiency, exquisite printing, moisture-proof, 80 ℃ temperature resistance and cold resistance. Under the premise of high efficiency and high quality of biodegradable materials, Quanyi has rich production experience.
