The price of high-density polyethylene (HDPE) has fluctuated significantly from 2017 to 2024, reaching a low of *** U.S. dollars per metric ton in 2020 and a high of U.S. dollars per metric ton in 2018. The price was shown to have decreased slightly from this 2023 value of *** U.S. dollars per metric ton to *** U.S. dollars per metric ton in 2024.

HDPE as a petrochemical derivative

One of the main factors that influences the HDPE market is the price of the raw material ethylene. Ethylene is a petrochemical product that is significantly affected by global oil prices and supply and demand dynamics. In 2021 the global ethylene market size was valued at *** billion U.S. dollars and was forecast to increase to a value of *** billion U.S. dollars by 2030.

Environmental concerns and HDPE alternatives

HDPE poses significant environmental concerns due to its non-biodegradability and challenges in recycling. Since 1950, the global production of plastic materials has exceeded **** billion metric tons, but only **** percent of them have been recycled. The remaining plastic waste has been either discarded in landfills or released into the environment. As one of the most widely manufactured plastics worldwide, HDPE waste can accumulate over time, leading to pollution and adverse health effects for both humans and animals. To address these issues, various alternatives to HDPE are being developed or utilized, such as bioplastics, synthetic paper, and bio-based HDPE. These alternatives aim to mitigate the environmental impacts of HDPE by utilizing renewable resources, biodegradable materials, or minimizing carbon emissions. However, these alternatives also have notable drawbacks, including higher costs, reduced performance, and the potential for competition with food crops.
