The hope against plastic pollution

As I sit here writing, various items lie before me - my laptop, a water bottle, a damaged calculator, a car key, and an earbud. The common link between all these objects is plastic. The casing of my laptop is plastic, the water bottle is plastic, the calculator’s casing is plastic, the car key has a plastic handle, and even the earbud casing is plastic.

Our World is Simply Dominated by Plastics

When these objects reach the end of their usefulness, the plastic either gets recycled or discarded into the environment. I'm in Nigeria, and the chances that these plastic wastes will be recycled are almost zero. This widespread reliance on plastic has become a pressing concern due to its environmental impact, especially in the form of pollution.

In developed countries, the recycling of plastic averages between 9% and 15%. For example, in the United States, only about 9% of plastic waste is recycled, while Europe achieves a slightly higher recycling rate, averaging around 15%. This disparity in recycling rates can be attributed to the advanced waste management systems in Europe.

In contrast, developing countries, such as Nigeria, face much lower recycling rates, often struggling to reach even 5%. This issue arises mainly due to the lack of infrastructure and the scarcity of resources necessary for effective waste management and recycling initiatives.

The severity of the plastic problem becomes more apparent when we examine the statistics surrounding plastic waste. Developed countries contribute a significant share of global plastic waste, with the nations of the Organization for Economic Co-operation and Development (OECD) accounting for approximately 53% of the world’s plastic waste. In total, high-income countries generate about 683 million tonnes of municipal waste each year, with a considerable portion of this being plastic.

Although developing nations produce less plastic waste per capita, they face even more challenges with waste management. As previously noted, Asia alone is responsible for 80% of the plastic waste that enters the world’s oceans. Plastics are made from petrochemical compounds, which are resistant to decomposition, and as a result, they accumulate in the environment for extended periods. The remainder of this plastic waste is typically sent to landfills, incinerated, or disposed of improperly, further exacerbating pollution.

Given that more than 99% of the world’s plastics are non-biodegradable, the current state of our oceans comes as no surprise. Plastics not only make the oceans unsightly but also pose a significant threat to aquatic environments, disrupting human activities such as fishing and navigation. Plastic waste in the water causes long-lasting damage, both to marine ecosystems and the livelihoods that depend on them.

One of the most devastating effects of plastic pollution is its impact on marine biodiversity. Marine animals often become entangled in plastic waste or mistake it for food, leading to injury, malnutrition, or poisoning. Additionally, plastics disrupt critical habitats, such as coral reefs and seagrass beds, releasing toxic chemicals that accumulate in the food chain.

These chemicals harm aquatic life, and the presence of microplastics further exacerbates the problem. These tiny particles infiltrate the food web, affecting organisms as small as plankton, which in turn threatens the stability of entire ecosystems. As a result, the biodiversity of our oceans is in peril, endangering various species and disrupting the balance of marine ecosystems.

However, there is hope on the horizon. Recently, researchers from Japan's RIKEN Centre for Emergent Matter Science announced a breakthrough in the development of a biodegradable plastic that dissolves in seawater within hours.

Unlike conventional plastics, which persist in the environment for centuries, this new material is designed to break down rapidly, offering a promising solution to the ever-growing problem of plastic pollution. The plastic is not only non-toxic but also food-safe and highly versatile, making it suitable for various applications, including packaging and medical devices. Its ability to degrade quickly in natural environments, whether in the ocean or on land, makes it a more sustainable alternative to traditional plastics.

In soil, this innovative plastic decomposes within just ten days, converting it into organic matter that enriches the soil and restores its carbon content. This decomposition process boosts soil fertility and does not contribute to the emission of greenhouse gases, unlike conventional plastics that release carbon dioxide as they break down.

As a result, this new biodegradable plastic presents a dual benefit: it reduces plastic waste and offers a potential solution to the challenges posed by climate change. The material could significantly impact waste management strategies, with potential applications in eco-friendly packaging and healthcare industries.

While this discovery offers a glimmer of hope, the critical question remains: will this breakthrough lead to widespread adoption and practical use of biodegradable plastics, or will it be relegated to the realm of unfulfilled potential? Only time will tell if this revolutionary material can scale up and address the pressing environmental challenges posed by plastic pollution, but it represents a significant step forward in the pursuit of sustainable solutions.
