Biodegradability has emerged as a critical factor in creating a sustainable future. The need for eco-friendly alternatives has led to the development of various types of biodegradable materials, including oxo-biodegradable materials. In this article, we will explore the differences between biodegradable and oxo-biodegradable materials, their impact on the environment, and their potential applications.
Biodegradable materials are substances capable of breaking down and decomposing naturally by the action of microorganisms, such as bacteria or fungi, over a period without causing any harm to the environment. These materials are often made from organic compounds, such as plant-based materials like corn starch or cellulose. Biodegradable products include items like compostable food containers, cutlery, and packaging materials.
On the other hand, oxo-biodegradable materials are conventional plastic materials that contain additives that accelerate their degradation process. These additives make the plastic undergo a process of fragmentation instead of complete degradation. Oxo-biodegradable plastics generally contain metal salts, such as manganese or iron, which act as catalysts to speed up the oxidation of the plastic when exposed to sunlight or heat.
The main difference between biodegradable and oxo-biodegradable materials lies in the end result of their degradation process. Biodegradable materials completely break down into natural elements, like carbon dioxide, water, and biomass. This process is often facilitated by the presence of microorganisms in the environment. In contrast, oxo-biodegradable materials break down into smaller fragments, but they do not fully decompose into natural elements. These fragments can persist in the environment for a significant period and may contribute to microplastic pollution.
While both biodegradable and oxo-biodegradable materials offer potential environmental benefits compared to traditional plastics, there are concerns regarding the long-term impact of oxo-biodegradable materials. The fragments left behind by oxo-biodegradable plastics can persist in the environment for many years, potentially causing harm to wildlife and ecosystems. These fragments can also enter the food chain through ingestion by marine animals, leading to potential health risks for humans.
Several countries have taken measures to address the concerns surrounding oxo-biodegradable plastics. For instance, the European Union has restricted the use of oxo-biodegradable plastics in certain applications due to the lack of evidence supporting their complete degradation without harming the environment.
When considering the application of biodegradable or oxo-biodegradable materials, it is essential to evaluate their specific use case and potential environmental impact. Biodegradable materials are well-suited for single-use items like disposable cutlery and packaging, as they will decompose within a short period and leave minimal harm to the environment. However, in applications where longer durability is required, such as in construction or automotive industries, alternative materials or recycling options may be more suitable.
The choice between biodegradable and oxo-biodegradable materials ultimately depends on the specific environmental goals and considerations. While biodegradable materials offer a more sustainable solution that promotes the restoration of natural resources, oxo-biodegradable materials can provide a transitional option for industries looking to reduce their environmental footprint without compromising on conventional plastic properties. Nevertheless, further research and developments are needed to address concerns associated with the persistent fragments of oxo-biodegradable plastics.
In conclusion, both biodegradable and oxo-biodegradable materials represent viable alternatives to traditional plastics by offering potential benefits for reducing environmental impacts. Biodegradable materials fully decompose into natural elements, while oxo-biodegradable materials break down into smaller fragments but may persist in the environment. The choice between these materials should be made considering their specific applications and environmental implications, with the ultimate goal of minimizing harm to ecosystems and promoting a sustainable future.
