Disposal of plastic lunch boxes and biodegradable lunch boxes

Affected by the global “plastic restriction” and “plastic ban” laws, large-scale plastic restrictions have begun in some parts of the world and domestic plastic ban policies have been gradually implemented, and the demand for degradable plastics continues to grow. According to statistics from IHS Markit, the global production of degradable plastics in 2019 was 1.174 million tons, and it is expected to reach 1.334 million tons in 2024. In January 2020, the National Development and Reform Commission and the Ministry of Ecology and Environment issued the “Opinions on Further Strengthening Plastic Pollution Control”, clearly proposing to ban and limit the use of disposable plastic products step by step and by field, and promote and apply degradable packaging films and plastic bags. , plastic film and other alternative products, the policy has been upgraded from “restricted” to “banned”. It will be divided into three time periods of 2020, 2022, and 2025 to clarify the phased task objectives of strengthening plastic pollution control. In order to further promote the implementation of plastic pollution control, in July 2020, nine departments jointly issued the “Notice on Steadily Promoting Plastic Pollution Control Work” to coordinate the prevention and control of epidemics and plastic pollution control to ensure that plastic pollution by the end of 2020 will be completed as scheduled. Manage various phased objectives and tasks. Under the background of favorable policies and technological progress, non-degradable plastic alternative materials will welcome development opportunities. Just like our pp lunch box is replaced by a biodegradable lunch box.

Biodegradable plastics are the mainstream materials to achieve degradation and substitution, but they have become a bottleneck in the realization of substitution decisions. Raw plastics are one of the most important products in the chemical industry. Due to their strong functionality, good processability, and ease of large-scale production, plastics continue to create new applications and continue to replace other traditional materials. In 2019, the global plastics The output has reached 400 million tons, and it is the most important material for building human society. Traditional materials such as wood, stone, glass, and metal will decompose into various forms and return to the natural cycle after a period of time, but plastics are completely man-made, and most of them are difficult to decompose after hundreds of years. Form the “white pollution” problem that the society is very concerned about now. In order to not only enjoy the performance and cost advantages of plastics, but also alleviate the harm of waste plastics to the environment, degradable plastics have emerged as the times require.
