What are the new eco friendly plastics? What are the new eco friendly materials that replace plastic

Using crab shells and wood as raw materials, environmentally friendly films are expected to replace existing food preservation plastics.

The materials the researchers extracted from crab shells and trees were chitin and cellulose, respectively. They alternately sprayed the chitin nanovibrillary fiber suspension and cellulose nanocrystal suspension on the polylactic acid film as the substrate, and after drying, a new type of film composed of chitin nanofiber layer and cellulose nanocrystal layer was formed. The film is not only flexible, transparent, but also biodegradable, making it environmentally friendly.

Thanks to its crystal structure, the new film can effectively prevent oxygen molecules from penetrating and become a barrier material with high air tightness. Compared to petroleum-based polyethylene terephthalate (PET), which is currently commonly used in food packaging, the oxygen permeability of the new film is reduced by 67%.

For food packaging, it is important to effectively prevent oxygen penetration. Theoretically, the less breathable the packaging material, the easier it is to keep the food fresh, so this new film with excellent air tightness is a good food preservation packaging material.

Particles dissolve quickly.

The University of Bath in the United Kingdom recently issued a press release saying that experts in the university's research on sustainable chemical technology use lignin to produce a micro-particle, which can be added to daily chemical products instead of microplastics.

Lignin is a tough fiber that is widely found in plants. The researchers dissolved the lignin and passed the solution through a porous membrane, forming tiny, round droplets, which then solidified into shape.

The researchers say the particles are strong enough for everyday chemical applications, but they are easily broken down by microorganisms into harmless sugars when they enter the sewer system, and can quickly degrade even when they enter the natural environment. They will work with industry to develop methods for mass production of such particles.

The above content reference: People's Daily Online-British scientists have developed environmentally friendly products to replace microplastics.

1. New environmental protection materials include formaldehyde-free wood-based panels, environmentally friendly coatings, insect-proof and mildew-proof coatings, wood wool sound-absorbing boards, plant fiber coatings, green paper-based wallpapers, polyester fiber sound-absorbing boards, expanded aluminum, green stone, antibacterial materials, etc.

2. The new decorative material is a new type of large-slab wall with green, environmental protection, energy saving, thermal insulation and fire resistance, which can be matched with domestic and foreign frame structures, steel structures and special-shaped column structure systems.

That's too much.

Some are integrated into the wall.

There's the wood veneer, or some other place.

Hello Qinqin Your question, here is the answer to your question: "Polypropylene carbonate is referred to as PPC, also known as polymethyl ethylene carbonate, which is a completely degradable environmentally friendly plastic synthesized by carbon dioxide and propylene oxide as raw materials, and it is also one of the most promising environmentally friendly plastics. It can be used in meat products (-80) cling film, degradable foam materials, plates, disposable tableware, disposable medical, food wide packaging materials, etc.

This resin has a low glass transition temperature and is often used to prepare products for use at low temperatures. The resin can also be blended with other types of plastics such as PP, PE, PC, etc., to improve the solvent resistance, oxygen barrier, etc.

1. Environmentally friendly flooring. Grass pavement bricks are one of a variety of porous paving products made from recycled high-density polyethylene. It can reduce storm runoff, reduce surface water pollution, and drain surface water. It is mostly used in public facilities.

2. Environmental protection wall materials. The newly developed aerated concrete bricks can be cut and formed with woodworking tools, masonry with a thin layer of mortar, and the surface is powdered with special brushed pulp, which has the effect of heat resistance and energy storage.

3. Environmental protection wall decoration. Straw wallpaper, hemp wallpaper, gauze wallcovering and other products have a variety of functions such as moisturizing, insect repellent, and health care. The anti-mold wallpaper is chemically treated, which excludes the mildew, foaming, and mildew breeding that occur when the air is humid or the temperature difference between indoor and outdoor is large, and the surface is soft and breathable.

4. Environmental protection pipes. Plastic-metal composite pipe is a high-tech product that replaces metal pipes, and its inner and outer layers are high-density polyethylene materials, and the middle is aluminum, which has the excellent properties of plastic and metal, and is not rusty and pollution-free.

5. Environmentally friendly paint. Bio-latex paint, in addition to easy construction, has a variety of colors, can bring colorful colors to the home. It will emit a fresh fragrance after painting, and it can also be repainted or treated with detergent to suppress mold in the wall.

6. Environmental protection lighting. This is a lighting system that aims to save electricity and protect the environment. Through scientific lighting design, the use of efficient, safe and illuminator products to create a comfortable, economical and beneficial lighting environment.
