What You'll Learn
Plastic in healthcare
Plastic has indeed become an integral part of our lives, and its usage in the healthcare industry is no exception. The use of plastic in healthcare is extensive and ranges from packaging, personal protective equipment, syringes, blood bags, gloves, tubing, sample tubes, and intravenous administration products to sterilization wraps and medical devices.
The global medical plastics market is currently valued at US$22.26 billion, or 2% of total plastics production by value, and is growing by 6.1% per year. The US consumes the most medical devices globally, followed by Europe and Japan. The growth in this sector is likely driven by the increasing demand for healthcare in developing countries. The manufacture of plastics accounts for 8% of global oil production, with oil being used as a feedstock and fuel.
The COVID-19 pandemic and the surge in the manufacturing, use, and demand for masks, gloves, and auto-tests have significantly increased plastic waste in the healthcare industry. The NHS in the UK, for example, produces around 2,500 tonnes of plastic waste daily, constituting 22.7% of its total waste. In Europe, 36% of healthcare waste is reportedly made of plastic, and in the US, it is estimated that around 1.7 million tonnes of plastic waste are produced annually by the healthcare sector.
The environmental impact of plastic waste in healthcare is significant. Plastic fragments comprise 50%–80% of shoreline debris, and while the exact proportion of medical waste in this figure is unknown, it is clear that plastic waste from the healthcare industry is contributing to this issue. Additionally, 42% of the plastic waste generated by the healthcare sector is burned, negatively impacting the climate and the environment.
While plastic has improved sterility and saved lives, it is essential to address the plastic waste problem in healthcare. Some possible solutions include reducing, reusing, repairing, and recycling plastic products, as well as proper disposal methods. Discussions and initiatives, such as the United Nations Environment Assembly resolution in March 2022, aim to develop legally binding instruments to address plastic pollution throughout its life cycle. Healthcare professionals are also taking steps to limit plastic purchases, encourage recycling, and engage with manufacturers about their plastic use and sustainability.

Plastic alternatives
While a world without plastic seems ideal for the planet, it is unrealistic. Plastic has improved our quality of life and fuelled innovation in many ways, from food security to medical equipment. However, we can certainly reduce our dependence on single-use plastic and adopt more sustainable alternatives.
One of the biggest sources of plastic waste is packaging, including food wrappers, bottles, and shipping materials. Sustainable alternatives to plastic packaging include biodegradable algae-based packaging. For instance, the Norwegian startup B'zeos uses seaweed to create biodegradable condiment packets, cutlery, drinking straws, and plastic wrap. Another leader in seaweed-based products is the 2022 Earthshot winner Notpla, which produces seaweed-based compostable takeout containers and cutlery.
Other alternatives to plastic packaging include natural fibres such as coconut fibre, hemp, husk, oat hulls, cotton burs, and jute. In 2022, scientists at Rutgers University, in partnership with Harvard University, developed an antimicrobial and biodegradable spray-on protective coating for produce and other food items. This coating, made from plant cellulose, is designed to be rinsed off with water and degrade in soil within 3 days, eliminating the need for plastic packaging for fruits, vegetables, and even meat.
When it comes to replacing polyester and nylon clothing, traditional alternatives include cotton, wool, linen, and hemp. However, scaling up production to meet current demand would be costly, as cotton already accounts for 16% of insecticide use and 2.5% of arable land worldwide. Instead, we should opt for more durable clothing items and move away from fast fashion.
In the healthcare industry, many plastic medical items are essential and have helped save lives, especially during the COVID-19 pandemic. However, there are proposed solutions to increase recycling in medical contexts, such as using 3D printing to create plastic ventilator valves.
While plastic is lightweight and inexpensive, it is important to consider the entire lifecycle of plastic products, from the extraction of raw materials to their end-of-life impacts. By reusing and refilling packaging, buying unpackaged goods, and supporting innovative alternatives, we can reduce our plastic consumption and transition towards a more sustainable future.

Plastic pollution
Plastic has become an integral part of our lives, with its use in various industries, including food, healthcare, and transportation. However, the ever-increasing plastic pollution has led to devastating environmental impacts, and there is a growing need to address this global issue.
The impact of plastic pollution extends beyond environmental degradation. It harms ecosystems, increases human health risks, accelerates climate change, and exacerbates societal inequities. The production, use, and disposal of plastic have severe consequences, and it is essential to address this issue through a collaborative approach.
To combat plastic pollution, a transition to a circular economy is proposed. This involves moving away from single-use items and redesigning products to be more durable, reusable, repairable, and recyclable. It also entails changing consumer behaviour and working with governments and businesses to build a sustainable future.
Additionally, a globally coordinated approach, such as an international treaty, is vital to reducing plastic production and refining the types of plastics to be more recyclable. Negotiators and leaders have the ability to significantly reduce plastic pollution by 2050 through policy interventions and global agreements.

Plastic production
Plastic is made from natural materials such as cellulose, coal, natural gas, salt, and crude oil. The production of plastics begins with the distillation of crude oil in an oil refinery, which separates the heavy crude oil into lighter components called fractions. One of these fractions, naphtha, is crucial for plastic production. The two main processes used to produce plastics are polymerisation and polycondensation, both of which require specific catalysts.
The world's first fully synthetic plastic was Bakelite, invented in 1907 by Leo Baekeland, who coined the term "plastics". Since then, dozens of different types of plastics have been produced, including polyethylene, commonly used in product packaging, and polyvinyl chloride (PVC), used in construction and pipes for its strength and durability.
The success and dominance of plastics have had major benefits for mankind, from medical devices to lightweight construction materials. Plastic has improved food security, increased the sterility of medical equipment, contributed to safety equipment, enhanced energy efficiency through insulation, and reduced weight in transportation.
However, the environmental problems caused by plastic pollution have overshadowed these advantages. Plastic waste is widespread, with microplastics found in Antarctic sea ice, the deepest ocean trenches, and drinking water worldwide. The annual production of plastics has increased nearly 230-fold in the last seven decades, with the world producing about 350 million tonnes of plastic waste each year. While it is challenging to recycle plastic, the key to a sustainable future lies in reducing plastic production and building a circular economy through collaboration between governments, businesses, and consumers.

Plastic recycling
Plastic has become an integral part of our lives, from food security to medical equipment, and even in safety equipment. However, the environmental impact of plastic waste is undeniable, and the world is now awash with plastic pollution. Plastic recycling is the process of converting plastic waste into other products, reducing the amount of waste that ends up in landfills and protecting the environment from pollution and greenhouse gas emissions. While recycling has been advocated since the 1970s, it has faced economic and technical challenges, and the plastic industry has been criticised for not doing enough to address the waste problem.
The process of plastic recycling typically involves melting and reforming plastic into new items. This can be done with most types of plastic, including polyethylene terephthalate (PET) and polypropylene, which are commonly used in food packaging. However, special processing is required to ensure these recycled materials are safe for food contact, and this adds to the cost. Feedstock recycling is another method, where plastic waste is converted back into its starting chemicals, which can be used to create fresh plastic. This process, however, requires higher energy and capital costs.
Despite these challenges, many local authorities are now offering recycling programmes for plastic bottles and mixed plastics packaging. In the UK, 99% of local authorities collect plastic bottles, and many are also collecting mixed plastics such as pots, tubs, and trays. Additionally, there are ongoing investments in technology to expand the range of plastics that can be recycled, including flexible pouches.
While recycling is an important part of reducing plastic waste, it is not the only solution. To truly address the global problem of plastic pollution, a more comprehensive approach is needed, including reducing plastic consumption, reusing plastics whenever possible, and advocating for policies and treaties that promote sustainable practices and hold companies accountable for their plastic waste. Individual actions, such as rejecting single-use plastics, can also have a significant impact and send a signal to businesses to change their practices.
