Why don't we use biodegradable plastic?

Plastic pollution has become a global environmental crisis, with devastating effects on ecosystems, wildlife, and human health. To combat this issue, many have called for the increased use of biodegradable plastics as an alternative to traditional plastics. However, despite their potential, biodegradable plastics have not gained widespread adoption. In this article, we will explore why we don't use biodegradable plastics and discuss the challenges associated with their implementation.

Firstly, it is important to understand what biodegradable plastics are. Unlike traditional plastics, which take hundreds of years to decompose, biodegradable plastics are designed to break down into natural substances such as water, carbon dioxide, and biomass through the action of living organisms, such as bacteria or fungi. This process is known as biodegradation, and it can occur in various environments, including landfills, composting facilities, and even in the ocean.

One major reason for the limited use of biodegradable plastics is the perception that they are more expensive than traditional plastics. The production of biodegradable plastics requires specialized materials and manufacturing processes, making them more costly to produce. This increased cost is often passed on to consumers, making biodegradable plastics less competitive in the market. Until the cost of biodegradable plastics becomes more affordable for mass production, it may be difficult to justify their widespread use.

Another challenge associated with biodegradable plastics is their limited availability. While traditional plastics are produced on a large scale and readily available, the production and distribution of biodegradable plastics are still relatively limited. This limited availability may be due to the slower adoption of new technologies and the need for greater investment in infrastructure to support biodegradable plastic production and recycling. As a result, many consumers and businesses may not have access to biodegradable plastic options.

Furthermore, the biodegradability of plastics is not a one-size-fits-all solution. There are different types of biodegradable plastics, each with its own set of characteristics and requirements for decomposition. For instance, some biodegradable plastics are designed to decompose only in specific conditions, such as industrial composting facilities with controlled environments. If these plastics end up in landfills or the natural environment, they may not degrade as intended, potentially leading to the same environmental issues caused by traditional plastics. Therefore, the proper management of biodegradable plastics is essential to ensure their effectiveness and prevent unintended consequences.

Additionally, the market demand for biodegradable plastics is still relatively low compared to traditional plastics. Many consumers remain unaware of the environmental consequences of plastic pollution and continue to prioritize convenience and affordability over sustainability. Without sufficient demand, manufacturers may be reluctant to invest in the production of biodegradable plastics, further limiting their availability and affordability.

There is also a concern that the use of biodegradable plastics could inadvertently contribute to increased plastic consumption. If people perceive biodegradable plastics as a solution to the plastic pollution problem, they may feel less motivated to reduce their overall plastic consumption. This could lead to an even greater demand for plastics, both traditional and biodegradable, ultimately exacerbating the issue instead of solving it.

In conclusion, while biodegradable plastics offer potential benefits in addressing the plastic pollution crisis, their limited adoption can be attributed to cost, availability, variability in biodegradability, low market demand, and unintended consequences. To promote the use of biodegradable plastics, it is crucial to address these challenges through technological advancements, infrastructure investments, education and awareness campaigns, and policy changes aimed at incentivizing sustainable alternatives. Only by addressing these issues can we truly harness the potential of biodegradable plastics and work towards a more sustainable future.
