As the sun rises higher in the sky and South Africa’s stunning coastline beckons with the promise of warm sands and refreshing ocean waves, many are eager to embrace the start of beach season in November. It’s truly a time for relaxation, surfing, and reconnecting with nature.
Yet, beneath the sparkling surface of our oceans lies a growing concern—microplastics. These tiny plastic particles, less than 5mm in size, have infiltrated our waterways at alarming rates, affecting the quality of our drinking water, food, and wildlife. As the beach season begins, it's important to reflect on how microplastics impact our environment and how we can manage plastics responsibly to prevent further harm.
Despite the growing awareness of plastic waste, South Africa’s rivers, streams, and oceans are still plagued by microplastic contamination. Plastics that are not part of a circular economy often end up in our waterways, eventually making their way into the ocean. This pollution affects not only marine ecosystems but also inland bodies of water, such as rivers and dams.
Whether through folly or poor waste management practice, when packaging (and other kinds of plastic products) finds its way into our oceans, it will eventually be broken down into tiny particles due to the heat of the sun, contact erosion, and the current. These particles are known as microplastics, spreading globally with the tides. (Source)
Alarmingly, microplastics have even been detected in tap water, highlighting that plastic waste, if not properly managed, poses a serious threat to human health and environmental sustainability. Circular solutions like those promoted by Mpact are crucial in preventing further pollution and ensuring that plastic waste is managed responsibly.
Microplastics are pervasive in oceans, posing significant threats to marine organisms. These particles often absorb harmful chemicals, becoming toxic and mistaken for food by marine life, leading to health risks. This has been well-documented with research on how these plastics accumulate in marine species and potentially impact humans who consume seafood. (Source)
In addition to seafood, studies suggest that microplastics have made their way into products like honey, beer, and many other consumable products. This widespread contamination leads to growing concerns about the long-term implications of ingesting toxin-laced plastics. (Source)
Microplastic pollution threatens marine life and has significant economic implications for South Africa. The country's economy heavily depends on its water resources for agriculture, industry, and tourism. Polluted rivers, such as the Vaal, which supports nearly half of the country’s GDP, are at risk of further degradation from plastic contamination.
The tourism and fishing industries are highly vulnerable to the effects of plastic pollution. Clean beaches and healthy marine ecosystems are vital for attracting tourists, while seafood contaminated with microplastics threatens public health and the viability of marine-based industries. If the issue persists, it could affect the viability of these industries and the safety of the food they produce. (Source)
To fully address the issue of microplastics, greater public awareness and stronger policies are needed. While recycling campaigns are common, the specific dangers posed by microplastics remain under-recognised. A circular economy approach—where products like plastics are reused and recycled—must be at the forefront of our waste management strategies.
South Africa is fortunate to have companies like Mpact Plastics and Mpact Recycling leading efforts to create sustainable solutions that keep plastics in circulation rather than in the environment. However, individual responsibility also plays a key role. People can contribute by participating in clean-up efforts, and supporting policies that promote circularity and sustainability.
As we head to the beaches, let’s enjoy the sun, sand, and surf and take responsibility for our impact on the environment. By supporting circular solutions, reducing plastic waste, and spreading awareness about the importance of proper plastic management, we can protect South Africa’s beautiful coastline for future generations.
While the environmental challenges posed by plastic are significant, it’s important to emphasise that certain plastics (such as PET) are not inherently harmful. The danger arises when plastics are not properly managed or recycled.
South Africa’s plastics industry, which is essential to daily living and economic growth, produces materials vital for society. However, these materials can quickly become an environmental crisis without responsible disposal and recycling.
Thankfully, Mpact Plastics, in partnership with Mpact Recycling, promotes circular solutions that help keep plastics out of waterways and the broader environment. Our focus on recycling and reusing plastic waste ensures that materials are kept within the collection & recycling value chain, rather than becoming waste. This commitment to sustainable practices highlights how plastics can be beneficial when managed in a way that prioritises recycling and the environment.
As beach season approaches, we must consider the implications of not adopting a recycling regimen. The sand, sea, and surf may be top-of-mind in these warmer seasons, but efforts to keep plastic waste from our oceans (and the greater environment) must be sustained all year round. Through unity, circular thinking, and circular acts, it’s entirely possible to turn the tide.
