What are the disadvantages of oxo-biodegradable?

Oxo-biodegradable materials have gained popularity over the years due to their claimed ability to degrade faster than traditional plastics. However, these materials have faced criticism and controversy, as there are several disadvantages associated with their use. In this article, we will explore some of the disadvantages of oxo-biodegradable materials.

Firstly, there is a lack of consensus on the actual biodegradability of these materials. While oxo-biodegradable materials are marketed as environmentally friendly, there are concerns that they may not degrade as quickly and effectively as advertised. The degradation process of oxo-biodegradable materials involves the breakdown of the plastic into smaller fragments, which leads to microplastics pollution. These microplastics can pose serious risks to ecosystems and marine life.

Furthermore, the process of degradation for oxo-biodegradable materials requires specific conditions, such as the presence of oxygen and exposure to sunlight. In environments lacking these necessary conditions, the degradation process may be significantly delayed or even halted altogether. This limitation raises questions about the reliability and effectiveness of oxo-biodegradable materials in various settings and geographic locations.

Another disadvantage of oxo-biodegradable materials is the potential for physical fragmentation. As these materials degrade, they can break down into small, brittle fragments. These fragments can become dispersed in the environment, making them difficult to collect and dispose of properly. This fragmentation can also result in the formation of microplastics, which have been found to accumulate in soil, water bodies, and even in the food chain.

Oxo-biodegradable materials also face criticism for their potential negative impact on recycling systems. The presence of oxo-biodegradable plastics in recycling streams can contaminate the entire recycling process. These materials can compromise the quality of recycled plastic and hinder the production of high-quality products. As a result, the recycling industry has been cautious and hesitant in accepting these materials, which could undermine efforts to promote a circular economy and reduce plastic waste.

Additionally, oxo-biodegradable materials have been met with skepticism from various organizations and institutions. For instance, the European Union's Scientific Committee on Health, Environmental, and Emerging Risks (SCHEER) has expressed concerns over the lack of supporting evidence on the biodegradability claims made by these materials. The committee has pointed out that there is a need for standardized test methods to accurately assess the biodegradability of oxo-biodegradable plastics.

Moreover, there are concerns that the use of oxo-biodegradable materials may lead to a false sense of sustainability. The perception that these materials are environmentally friendly may discourage individuals and businesses from seeking alternative, more sustainable options. This could delay the transition to truly biodegradable or compostable materials, which have been proven to be more effective in reducing plastic pollution.

In conclusion, while oxo-biodegradable materials may appear to offer a solution to the problem of plastic waste, they come with significant disadvantages. The lack of consensus on their biodegradability, the reliance on specific conditions for degradation, the potential for physical fragmentation, their impact on recycling systems, skepticism from experts, and the risk of promoting a false sense of sustainability are all concerns associated with oxo-biodegradable materials. As the world searches for sustainable alternatives to traditional plastics, it is essential to critically evaluate the drawbacks of oxo-biodegradable materials and prioritize long-term, genuinely sustainable solutions.
