Plastic is a topic that often comes up in discussions about environmental issues, and for good reason. While plastic waste is a major problem, plastic does have some benefits. One way plastic is helpful is by extending the shelf life of food, which reduces food waste and greenhouse gas emissions. Plastic packaging also helps keep food safe from oxygen, light, temperatures, moisture, microbes, dirt, and pests. Additionally, plastic is used in medical instruments, vaccine syringes, surgical gloves, insulin pens, IV tubes, and catheters, playing a crucial role in protecting our health and fighting diseases. During the COVID-19 pandemic, plastic PPE was essential in safeguarding frontline healthcare workers. Furthermore, lightweight and durable plastic auto parts contribute to improved fuel efficiency and reduced greenhouse gas emissions from vehicles. However, it's important to note that the benefits of plastic should not overshadow the need to reduce, reuse, and recycle plastic products to minimize their environmental impact.

Plastic packaging helps preserve food, reducing food waste and increasing shelf life
Plastic packaging offers a protective barrier for food, preventing defects that occur with other types of packaging. It is particularly useful for protecting delicate items, such as eggs, and preventing spoilage during transportation. Plastic packaging can also be designed to include thermoformed sections to keep different foods separate.
The type of plastic used for food packaging is important. PP (polypropylene) plastic, for example, has a high melting point, making it ideal for storing microwaveable dishes, yogurt, and ice cream. However, it is flammable and susceptible to UV degradation and oxidation. PET plastic is often used for grab-and-go food containers and bottles for condiments, as it is transparent and showcases the food inside.
Overall, plastic packaging helps to extend the shelf life of food products, reducing food waste and minimizing the carbon footprint of the food industry. While there are valid concerns about the environmental impact of plastic, it is important to recognize that plastic packaging plays a significant role in preserving food and reducing waste.

Plastic is used in life-saving products such as helmets, airbags, and medical instruments
Plastic is used in a wide range of life-saving products, including helmets, airbags, and medical instruments.
Helmets are often made with a plastic shell, which provides protection to the wearer. While there have been concerns about the potential leaching of chemicals like BPA from certain types of plastic helmet shells, such as polycarbonate, the benefits of protection are generally considered to outweigh the risks. Helmet manufacturers are also taking steps to address these concerns, with some employing sophisticated lab equipment to test their products for any potential issues.
Airbags are another life-saving product that utilizes plastic. Plastics, such as nylon, are increasingly being used in the production of airbag canister housings, offering advantages such as reduced weight compared to traditional metal housings. This contributes to the overall safety of the airbag system and the vehicles they are installed in.
In the medical field, plastics play a crucial role in the construction of medical devices and equipment. Medical instruments, such as bone hammers and chisels, benefit from plastic components that reduce their weight and improve grip, making them more ergonomic and enhancing performance during surgical procedures. Plastic is also used in single-use disposable items like syringes, surgical gloves, and catheters, helping to ensure sterility and reduce the risk of cross-contamination.
Overall, while there are valid concerns about the environmental impact and potential chemical hazards associated with certain plastics, their use in helmets, airbags, and medical instruments has undoubtedly contributed to advancements in safety and healthcare.

Plastic components enable everyday devices like cell phones and computers
Plastic is a versatile material that can be moulded and formed into almost any shape. It is used in a wide range of electronic products, including computers and cell phones. Plastic components are integral to the functioning of these devices, offering protection, enhanced user-friendliness, and weight reduction through light and compact parts.
Plastic is a popular choice for cell phone manufacturers due to its durability, aesthetic appeal, and cost-effectiveness. Polycarbonate, a type of plastic, is known for its high impact resistance, making it ideal for cell phone housing. It is also fully recyclable and reusable, making it a more sustainable choice. Other types of plastic used in cell phones include ABS, nylon, and polymethyl methacrylate (PMMA). These plastics offer excellent impact and heat resistance, as well as dimensional stability, making them suitable for casings, housings, and structural components.
In addition to enclosures, plastics are used in cell phones for mounting brackets, display frames, backlight guides, insulator sheets, and vibration cushions. The use of plastic in cell phones allows for greater variety in design and colour options, as well as reduced production costs.
Plastics are also commonly used in computer parts, such as monitors, printers, and keyboards. Injection moulding techniques allow for the creation of complex, intricate, lightweight plastic parts that are essential for many electronic applications.
While there are concerns about the environmental impact of plastic use in electronics, some manufacturers are taking steps towards sustainability. For example, Samsung aims to incorporate recycled resin into all of its plastic products by 2050, and Nokia has released a phone with up to 60% recycled plastic and recycled aluminium.

Plastic building materials can seal homes from the elements and reduce energy costs
Plastic building materials can seal homes from the elements and significantly reduce energy costs. Plastic insulation products such as spray foam, rigid foam, and house wrap can fill gaps and seal buildings from unwanted airflow, helping to maintain indoor temperature and comfort. This reduces the energy required for heating and cooling, saving homeowners up to 50% on their energy bills.
Plastic insulation also acts as a moisture barrier, preventing the accumulation of moisture in walls and reducing the chances of mold and mildew growth, thus protecting indoor air quality. Additionally, plastic building materials improve a building's R-value, a measure of how effectively insulation resists the flow of heat. Higher R-values mean better insulation and reduced energy loss, leading to lower energy costs and a reduced carbon footprint.
While modern plastic insulation materials may increase initial construction costs, they pay off in the long run through improved energy efficiency and reduced energy consumption. This not only benefits homeowners financially but also contributes to a more sustainable future by reducing greenhouse gas emissions.
Plastic, therefore, plays a crucial role in sealing homes from the elements and driving down energy costs, making it an essential material in the construction industry's efforts to create more energy-efficient buildings.

Plastic is lightweight and durable, improving vehicle fuel efficiency and reducing emissions
Plastic is an essential material in car manufacturing. It is durable, lightweight, and impact-absorbent. These properties make plastic ideal for exterior car components, such as fenders, bumpers, and mirrors, providing extra resilience and minimising the need for repairs.
The weight of a car is dictated by the mass of its components. Traditional car manufacturing materials such as steel and aluminium are strong and durable, but they are also very heavy. A heavy vehicle requires more fuel to run than a lighter vehicle, and so a heavier car will have worse fuel efficiency and produce more emissions.
The automotive industry is increasingly focused on sustainability and performance. Plastics are being used more and more in car manufacturing to reduce weight and improve fuel efficiency. From 2012 to 2021, the amount of plastic in cars increased by 16%, making up about 50% of the volume of a car but only 10% of its weight. This increase in plastic usage has improved fuel efficiency and reduced carbon emissions from transportation.
The use of plastics in car manufacturing also has other benefits. Plastic car components can be moulded into patterns that improve aerodynamics and increase airflow, further improving fuel efficiency. Additionally, plastic is more resistant to corrosion than metal, reducing the need for repairs and lowering costs for consumers.
