Polystyrene plastic (PS) or polystyrene foam (PSF) is one of the most widely used plastics in the world. He is a thermoplastic, with the third largest output after PVC and polyethylene. Polystyrene and its products are widely used in various packaging materials, advertising decoration, foam insulation materials, cushioning materials and disposable tableware. However, because PSF is mostly one-time application, it is easy to cause waste and its product density is small (usually 0.015-0.03). It is bulky and difficult to degrade. In addition, the toxic substances carried by the waste PS foam itself will pollute groundwater and damage the soil structure, becoming White pollution. It is necessary to recycle and use polystyrene and its products, which can reduce its environmental pollution and save resources to achieve economic benefits. Recycling technology of waste polystyrene foam: As white pollution becomes more and more serious, governments of all countries attach great importance ...

What is bioplastic? Biodegradable bag supplier  introduces you: "Bioplastic" means that all or part of it is made of organic natural materials instead of traditional petroleum. Many bioplastics are biodegradable. This is also one of the biggest advantages of bioplastics. There are three terms about bioplastics that describe "biobased plastics", "biodegradable plastics" and "compostable plastics". Although these terms are similar, they should not be confused. Bio-based plastic This is a very broad term that refers to the extraction of part or all of plastic from plants. Starch and cellulose are the two most common renewable raw materials used to make bioplastics. These ingredients usually come from corn and sugar cane. Bio-based plastics are different from common petroleum-based plastics. Although many people believe that all "bio-based" plastics are biodegradable, this is not the case. Biodegradable plastic bag Whether plasti...

Extensive research conducted by independent research institutions confirms Ecovio's strengths in food production, packaging and transportation, and waste collection, based on the material's certified biodegradability in industrial and domestic compost and soil. Studies have shown that biodegradable bag reduces food waste, returns nutrients to the soil by producing larger volumes of compost, and avoids the accumulation of plastic in the soil. Soil biodegradable mulch for sustainable agriculture Farmers in many countries use PE mulch to increase crop yields. However, after harvesting, it is often impossible for farmers to fully collect these films, especially when they are only a few microns thin. Therefore, PE residues find their way into the soil and accumulate there because they do not break down. Now, a study by the Federal Institute of Technology in Zurich, Switzerland, shows for the first time that soil microorganisms can use films made of plastic polybutylene adip...

Words such as "degradable" and "biomaterials" are easily misunderstood by the public, thinking that these plastics can be easily decomposed in nature and become part of nature like straw and leaves. Therefore, California issued a decree in 2008 to ban businesses from using the name “degradable plastic” for promotion. Biodegradable plastics  may not be recyclable. In addition, some degradable plastics mixed with other recyclable plastics will reduce the quality of recycled materials. (Separate classification and recycling of plastics of the same material can obtain better quality recycled materials. The performance of mixed recycled plastics may be unstable.) The United States of America's North Carolina and Alabama proposed a bill in 2013 that requires plastic products that are degradable, biodegradable, or compostable to be labeled as "non-recyclable" to avoid mixing into other recyclable plastic products. Correct recognition, detailed identifi...

Plastic is difficult to degrade, and it is easy to produce harmful substances when burning, which is a difficult problem for current garbage disposal. Especially film plastics are mostly disposable and difficult to recycle. In order to solve this problem, we have developed degradable plastics-which have the properties of traditional plastics and degradable. Green biodegradable bag wholesaler  to share with you: Degradable plastics may not be bio-based plastics. Green Biodegradable Vegetable Bag Green biodegradable vegetable bags  may use bio-based raw materials, but may also contain petrochemical raw materials (or a mixture of both) that enhance biodegradable additives. Bio-based raw materials are usually natural polymers (such as starch, cellulose, chitin) or agricultural and sideline products produced by microbial fermentation or synthesis of biodegradable polymers, such as thermoplastic starch plastics, polyhydroxy fatty acid esters (PHA), Polylactic acid (PLA)...
