What You'll Learn
Plastic's impact on medicine
Plastic has had a profound impact on the field of medicine. Its versatility, durability, lightweight nature, and cost-effectiveness have made it an invaluable material in healthcare.
One of the most significant contributions of plastic to medicine is in the development of disposable medical devices. The invention of the disposable plastic syringe in 1955 revolutionized healthcare by providing a cost-effective and sterile option for drug administration. This not only improved patient care but also helped reduce the spread of diseases associated with the reuse of syringes. Today, single-use disposable devices, such as syringes, intravenous (IV) bags, and tubing, account for 85% of medical equipment. These disposable items are crucial for immediate drug delivery, fluid replacement for dehydrated patients, blood transfusions, and correcting electrolyte imbalances.
Plastics have also found applications in tissue engineering, absorbable sutures, prosthetics, and joint replacements. Absorbable sutures, for example, are made of polymers that can be designed to biodegrade over different periods, eliminating the need for surgical removal and reducing the number of procedures a patient undergoes. Additionally, plastics have been used in the creation of polymer implants and other medical devices, enhancing patient treatment and recovery.
The lightweight and flexible nature of plastics has further benefited the pharmaceutical industry. Plastic packaging helps maintain the sterility of medical instruments and ensures the safe distribution of medications. It also extends the shelf life of pharmaceuticals, making them more accessible to patients worldwide.
While plastic has undoubtedly improved medical practices, concerns have been raised about the potential health risks associated with certain plastic components. For instance, human exposure to endocrine-disrupting chemicals like bisphenol-A (BPA) and di-(2-ethylhexyl)phthalate (DEHP) has come under scrutiny. As a result, there is a growing emphasis on eliminating these harmful uses of plastics and transitioning towards reusable and biodegradable alternatives.

Plastic pollution
Every year, about one to two million tons of plastic waste escapes into the oceans from coastal nations, polluting the water and affecting wildlife and ecosystems. Plastic often contains additives that make them stronger and more durable, but these same properties mean that plastic waste can take at least 400 years to break down. Once in the ocean, plastic can be transported by currents around the world, affecting even uninhabited environments. For example, scientists found plastic items from Russia, the United States, Europe, South America, and Japan on Henderson Island, an uninhabited island halfway between Chile and New Zealand.
The consequences of plastic pollution are dire, with millions of animals killed by plastics every year, from birds to fish to other marine organisms. Nearly 2,100 species, including endangered ones, are known to have been affected by plastics, with plastic found in more than 100 aquatic species, including fish, shrimp, and mussels destined for human consumption. Plastic pollution can also alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting millions of people's livelihoods, food production capabilities, and social well-being.
To combat plastic pollution, improving waste management strategies is crucial. While reducing plastic production is important, improving waste management would do more to reduce plastic pollution. This includes domestic policies to improve waste management and foreign investments in waste management infrastructure in poorer countries, where most ocean plastics originate. Public awareness of plastic pollution and support for government action to address the plastic crisis are also growing, with over 2.1 million people worldwide signing a WWF petition for a global treaty on marine plastic pollution.

Plastic's role in packaging
Plastic has had a significant impact on society, revolutionising packaging, transportation, medicine, and technology. In developed economies, about a third of plastic is used in packaging, and in developing countries, this figure can be even higher—for example, 42% of India's plastic consumption is used in packaging.
Plastic packaging allows us to protect, preserve, store, and transport products in a variety of ways. Its unique combination of benefits, including durability, safety, hygiene, and lightweight strength, has led to its widespread use. Plastic packaging is ideal for foodstuffs, medicines, and pharmaceuticals. It can be moulded into different shapes and sizes, making it suitable for a range of products. Its flexibility and ease of sterilisation also make it perfect for protecting fresh produce, preserving taste and nutritional value, and preventing contamination.
The lightweight nature of plastic packaging reduces fuel consumption and shipping costs, while its transparency enables users to examine the condition of goods prior to purchase, aiding inventory control. Plastic packaging also offers improved storage due to its durability and flexibility, and its tamper-evident and child-resistant closures enhance product safety.
However, the dominance of plastic has also led to widespread environmental problems due to its slow decomposition rate. Plastic collection and recycling have largely been ineffective, with most plastic ending up in landfills or persisting as pollution in the world's water bodies and ecosystems. While initiatives and technologies are working towards reducing single-use plastic and addressing the plastic pollution crisis, a holistic approach to sustainable plastic production, consumption, and waste management is still needed.

Plastic as a democratising force
Plastic has had a profound social impact, revolutionising industries from packaging and transportation to medicine and technology. Its unique properties, such as being lightweight, durable, flexible, and inexpensive to produce, have led to its widespread adoption.
Plastic has been hailed as a democratising force, making a wide range of goods accessible to the expanding consumption-oriented middle class. Before World War II, plastic was celebrated as a magical material that would bring about a utopia of material abundance and bridge the standard-of-living gap between rich and poor. It allowed for the creation of an infinite number of new objects and devices in various shapes, sizes, and colours, at a very low cost.
The development of modern plastic, Bakelite, in 1907, marked a significant turning point. As the first fully synthetic plastic, it opened the door to a vast family of products based on synthetic polymers. However, it was in the 1950s and 1960s that plastic truly took over, with improvements in manufacturing processes leading to dramatically reduced costs and enabling mass production.
The versatility and durability of plastic have made it a staple in numerous industries. In medicine, for example, the invention of the disposable plastic syringe in 1955 revolutionised healthcare. Plastic is also used in construction, home appliances, medical instruments, and food packaging, enhancing our daily lives and reshaping entire industries.
Despite the benefits, the proliferation of plastic has led to significant environmental concerns. Plastic pollution is widespread, with oceans and ecosystems suffering the consequences of ineffective recycling and disposal practices. However, it is important to note that simply replacing plastic with alternative materials would result in increased greenhouse gas emissions and consumption of packaging. The challenge, therefore, lies in mitigating the negative impacts of plastic while harnessing its benefits.

Plastic's environmental impact
Plastic has had a significant impact on society, and its production, use, and disposal have imposed countless negative impacts on the environment.
The production of plastic releases chemical pollutants and greenhouse gases (GHG) that contribute to climate change and can cause adverse health effects in humans. The refinement of plastics emits an additional 184 to 213 million metric tons of greenhouse gases each year. Landfills, where single-use plastics are disposed of, account for more than 15% of methane emissions. The disposal of more plastics in landfills leads to increases in landfill size and emissions. The extraction of fossil fuels and their transportation to plastic factories also emit greenhouse gases, with the removal of forested land for oil extraction releasing carbon dioxide into the atmosphere.
Plastic waste is either disposed of via processes that release chemical pollutants and contribute to climate change or leaks into the environment, becoming plastic pollution. Plastic pollution is one of the most pressing environmental issues today, with plastic production having almost doubled over the past two decades. Plastic trash has become ubiquitous, with about eight million tons of plastic waste escaping into the oceans from coastal nations each year. This waste is carried by rivers and ocean currents, spreading plastic pollution worldwide. An enormous floating mass of plastic in the Pacific Ocean, twice the size of Texas, continues to grow.
Plastic pollution alters habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting millions of people's livelihoods, food production capabilities, and social well-being. It puts marine species at higher risk of ingesting plastic, suffocating, or becoming entangled. Research indicates that more than 1,500 species in marine and terrestrial environments are known to ingest plastics, with nearly 2,100 species, including endangered ones, affected by plastics. Microplastics have been found in more than 100 aquatic species, blocking digestive tracts or piercing organs, causing death.
The durability of plastic means that the costs of waste management and the environmental and health impacts will be incurred for extended periods. Plastic takes hundreds to thousands of years to fully degrade, breaking down into smaller particles that are challenging to recover and remove from the environment. These microplastics are spread throughout the water column and have been found everywhere, from Mount Everest to the Mariana Trench.
To reduce the environmental impact of plastic, individuals can make small changes, such as using reusable bags, avoiding overly packaged items, repurposing old containers, supporting legislation that reduces plastic use, and buying products from companies committed to reducing plastic use.
