　　Plastic is one of the greatest inventions of the 20th century, but because it is “not environmentally friendly”, it has now been banned or abandoned in many fields. One of the products that replaced it is “degradable plastic”, such as compostable PLA straws. However, is degradable plastic definitely more environmentally friendly? How can it be degraded? How long does it take? Today we will learn more about the knowledge of degradable plastics.The data shows that, recycle trash bags Its development potential should not be underestimated, and it is also the inevitability of its existence. https://biodegradable-gd.com

　　If “degradable” is understood as an absolute concept, then all kinds of plastics can basically be degraded in some way in a long or short period of time and in some environment. If this discussion is meaningful, “degradable” should be understood as a relative concept-what substance (toxic or not) can be degraded in what way and in what environment in how long?

　　At present, the more authoritative definition of degradable plastics is: a type of plastic that can eventually be completely degraded into carbon dioxide (CO2) or/and methane, water (H2O) and mineralized inorganic salts of its elements and new biomass under various conditions in nature. In the definition, various conditions in nature are generally divided into six categories: soil, compost (including traditional compost and garden compost), marine environment, freshwater environment, sludge anaerobic, and high solid anaerobic. Therefore, for the definition of degradable plastics, we can summarize it in one sentence: most of the components of degradable plastics can be almost completely degraded into common substances in nature in the corresponding natural environment.

　　PLA is a biodegradable and bioactive thermoplastic derived from renewable resources such as corn starch, sugarcane, or cassava. Unlike petroleum-based plastics, PLA is designed to break down more readily under specific conditions. The process of making PLA involves fermenting the sugar from these renewable resources to produce lactic acid, which is then polymerized to form polylactic acid.

　　Degradable plastics on the market generally refer to biodegradable plastics. Biodegradation usually refers to the ability to completely degrade into carbon dioxide, water, inorganic salts and new biomass with the participation of microorganisms in nature. This is also the reason why everyone thinks biodegradable plastics are more environmentally friendly.Depending on the raw materials of plastics, biodegradable plastics can be divided into “bio-based biodegradable plastics” and “fossil-based biodegradable plastics”. The former is commonly polylactic acid PLA (mostly used for disposable straws), the raw materials are mainly corn starch, and may also be other biomass; the latter is commonly PBAT, which is made from petrochemical resources (including coal and oil). If you have biodegradable plastic bags at home, you can look at the product logo, which generally contains PBAT.

　　It can be seen that, whether bio-based or fossil-based, these biodegradable plastics are not like fallen leaves that can be completely degraded by simply throwing them on the ground. In theory, biodegradable plastics can be degraded or recycled in a variety of environments, but the best is to use industrial high-temperature composting to completely degrade them in a shorter period of time. According to this idea, degradable plastic waste should be thrown into kitchen waste bins or wet garbage bins, and then sent to industrial composting equipment.

　　Biodegradable PLA straws have the potential to degrade under specific conditions, primarily in industrial composting facilities. While they offer an improvement over traditional plastic straws in terms of environmental impact, their real-world effectiveness is limited by infrastructure and disposal challenges. To truly capitalize on the benefits of PLA straws, we must invest in better waste management systems, educate consumers, and continue to innovate in the field of sustainable materials. By doing so, we can move closer to a future where single-use items have minimal environmental impact.

　　Electroplating process – chrome plating

　　Chromium is a silvery-white metal with a slight sky blue tint. The chrome layer has high hardness, good wear resistance, strong reflective ability, and good heat resistance. There is no obvious change in gloss and hardness below 500＜C; it begins to oxidize and discolor when the temperature is greater than 500＜C; it begins to soften when it is greater than 700＜C. Due to the excellent performance of the chrome plating layer, it is widely used as a protective, decorative coating system’s surface layer and functional coating.

　　Custom made trophies and medals.jpg

　　Electroplating process – copper plating

　　Copper is easy to oxidize, and the oxidized patina is no longer conductive; copper plating is easy to lose its luster in the air, and reacts with carbon dioxide or chloride to form a layer of basic copper carbonate or copper chloride film on the surface. It will generate brown or black copper sulfide when it is exposed to sulfides. Therefore, as a decorative copper plating layer, an organic coating layer needs to be coated on the surface.

　　Price of metal medal production

　　The material is very important in the production of metal medals. One cent for one product has always been the value law of any industry and any commodity. It is difficult to get high-end products at a very low price.
