The advantages and applications of bioplastics

At present, the quality of bioplastics is constantly improving and gradually becomes an advanced and practical packaging material. Their performance can be compared with existing synthetic plastics. When they are processed, they can be degraded into low molecular products, which can be decomposed by naturally occurring microorganisms.

Quality In a project entitled "Industrial Crops and Applications", the European Plastics Association conducted a study on the market for degradable plastic materials and found that industrial degradable plastics are far superior to synthetic plastics in terms of quality. Biodegradable plastics should be considered for those markets where recycling is difficult and where the service life is short. Biodegradability is an application requirement or design requirement and it has characteristics that are most suitable for its intended application.

Environment There is no single but simple method for waste management, but there is a fairly wide range of options that include reducing the quality of goods entering the waste range and studying those biodegradation treatments. Synthetic plastics have durability and resistance to all types of degradation (including biodegradability). In addition, a large number of application features with various cost performances are also provided. However, when long-lasting plastics are used for short life cycle applications, the environmental burden will increase. Sustained development shows that the application of daily necessities design, production, consumption and special projects should consider their interaction with the environment so as to select the most suitable material.

Regulations Biodegradable plastics can save energy and benefit the environment. Its characteristics make this material compatible with European waste management policies. There is currently a need to establish a definition that includes all possible types of environmentally degradable plastics, as well as related standards and test drafts, the characteristics and results of which are key issues for acceptable degradable plastics.

European testing standards for measuring biodegradability under synthetic conditions are currently being established. The question that needs to be asked is whether the current testing standard accurately reflects the biodegradability of a substance in the real situation. The most critical issue is whether the biodegradable material is harmful to the environment. European CEN (European Standards Committee) and DIN (Deutsche Research fur Norcnung eV) have proposed joint standards. The CEN standard has become a guide for European packaging, and has successfully and effectively defined different methods and methods for the degradation of atmospheric microorganisms and anaerobic microorganisms. Coordinated.

Applications Bioplastics are expanding in scope and increasing in number. These include fast food packaging, foam packaging materials, sanitary cleaning products, disposable cutlery, bags, and food packaging films. The design and application of these packaging materials and supplies both consider and require biodegradability. Related applications include waste bags, paper laminate structures, hot melt adhesives and medical devices.

The Challenge In theory, in many applications, bioplastics can replace conventional synthetic plastics. In fact, these alternatives are often practicable. Technical work must be adapted to economic work, which depends not only on the investment required for materials, product development and production, but also on the added value of bioplastics in particular applications. There is only one clear value, that is, the impact on the environment can enable consumers to choose bioplastics at a price higher than that of normal plastics. Taking into account the added value of bio-plastics, the legislation that is appropriate to it will ensure that people will benefit from it.

In short, bioplastics are accepted by people, mainly relying on the ratio of price to environmental value, legislation, biodegradability, and the establishment of collection, use, and disposal of biodegradable polymer systems.
