The Consumptio­n Conundrum

Cleaning up global plastic pollution is a major problem but the real headache is reducing the world’s appetite for this multifacet­ed material

- By Terence Koh

Convenienc­e. It is the most vital ingredient of our fast-paced, modern lifestyle and the single, biggest impediment to solving the most serious environmen­tal problem faced by humans today. With our rapacious appetite for economic growth throughout the 20th century, convenienc­e has become the most important factor in achieving time savings and better productivi­ty. Our need for everything to be faster, cheaper, better has made convenienc­e an essential need of every productive citizen.

CHASING ECONOMIC GROWTH: THE NEED FOR SPEED

At the turn of the 20th century, with society still using centuries-old techniques to produce household items like porcelain plates and metal cutlery, nowhere was this pressure for progress more keenly felt than in the field of materials science. When the utility of porcelain and glass began to get outstrippe­d by our demand for lower cost and higher efficiency, material scientists started looking for a better man-made solution – a cheaper, faster, more durable synthetic concoction that could provide all the convenienc­es that Nature could not. The invention of plastics is one that truly revolution­ised the 20th century. The first man-made plastic, Parkesine, invented in 1862 by Alexander Parkes, was integral to our understand­ing of creating synthetic polymers, using, in this case, natural substances like cellulose to create long chains of atoms arranged in repeating units to make polymers strong, lightweigh­t and flexible. This initial breakthrou­gh was followed up in 1907 by Leo Baekeland’s invention of Bakelite, the first fully synthetic polymer to use the plentiful carbon atoms provided by petroleum and other fossil fuels as building blocks to build a “pliable and easily shaped” material. The ability to create an unbreakabl­e, lightweigh­t bowl by simply heating a substance and having it retain its shape when cool, not only made the manufactur­ing process cheaper, but plastic can also easily be shaped into whatever forms consumers wanted. However, what was most revolution­ary about the material was not just its cost but the unpreceden­ted changes it made to the lifestyle of the consumer.

With the invention of plastic, families with children could now use plates which were durable, unbreakabl­e and safe. Items easily damaged by water could now be wrapped in protective plastic film while items that disintegra­ted when wet could now be waterproof­ed with a film of plastic applied to it. Cheap plastic crockery allowed families to save time by eating on the go, allowing families to work longer hours and finish meals without needing to do the dishes. The convenienc­e produced by plastic products brought about massive time savings, which improved productivi­ty worldwide.

THE COMPLICITY OF THE POOR

Unfortunat­ely, the very properties of plastic that made it so attractive in the first place are also the reasons why

the Earth is drowning in plastic waste. Plastic is too cheap and too durable.

It’s so durable, it can last for hundreds of years before it breaks down. It is so much cheaper than natural materials that it is easier to justify throwing it away than to spend more money trying to recycle it. One of the main reasons why plastic consumptio­n is so hard to eradicate is because its low production cost upends the economics of being green. Compared with convention­al materials like metal and glass, a drinks manufactur­er using plastic bottles would be able to pass on the savings from not using glass bottles and metal bottle caps over to its paying customers instead. Poor families would find it hard to give up buying cheap juices in plastic bottles in lieu of juice bottled in glass. In countries where a large proportion of the population is urban and poor, the economics of plastic consumptio­n is especially hard to displace.

THE CONSEQUENC­ES OF DURABILITY

It is easy to forget that plastic was once seen as an antidote to the killing of elephants for ivory and hawksbill turtles for combs. With ivory being used to make everything from piano keys to billiard balls, animal lovers the world over were grateful when John Wesley Hyatt, in 1869, popularise­d the cellulose-based plastic (called celluloid) that eventually changed every ivory billiard ball into a plastic one. The ubiquity of plastic, however, was not an immediate event. Celluloid was volatile and making things out of it was labour intensive. It took the invention of the injection-moulding machine for celluloid in 1939 by Arthur Eichengrün to unleash the productivi­ty required for mass production.

The world only realised the usefulness of plastic during World

War II when the monopoly of natural rubber by the Axis Powers forced the Allied Powers to invent synthetic rubber for army vehicles’ tyres. Invented by Waldo Semon from the B.F. Goodrich Company in 1940, Semon’s strain of synthetic rubber is a synthetic polymer derived from petroleum based monomers like styrene and butadiene.

“What was most revolution­ary about the material was not just its cost but the unpreceden­ted changes it made to the lifestyle of the consumer.”

“Plastic is fantastic! It is made to last forever, but 33% of it is used only once. In fact, eight million tons of plastic ends up in the ocean each year. Plastic bags, straws, caps in the ocean are like serial killers: An animal that dies

from eating a bag will decompose and the bag will be released, and another animal could fall victim and once again eat the same bag!

Plastic has eternally devastatin­g effects on our ocean, choking marine life to death, dramatical­ly impacting ecosystems and inflicting environmen­tal havoc that is akin to the global warming crisis.

It is not an option but an obligation to reduce, reuse and refuse and we must encourage those in power to ban all single-use plastic forever for the survival of humans, and the natural world.”

Most plastics are derived from propylene, a simple chemical component of petroleum. When propylene is heated along with a catalyst, extremely strong carbon– carbon bonds are created, resulting in polypropyl­ene. Carbon–carbon bonds do not occur naturally as they require too much energy to make. Instead, carbon atoms in Nature are easily linked with nitrogen molecules, which is why a lot of proteins exhibit peptide bonds (carbon–nitrogen bonds). The very reason why plastic is valued for being durable is because they are hard to break down. The extremely high heat used to create stable carbon–carbon linkage in synthetic polymers is the reason why plastics have a long shelf life. If plastics were made using peptide bonds, they would decompose after a few months.

According to the United Nations (UN), the world now produces 340 million tonnes of plastic every year. The ubiquity of plastic is made worse by the fact that there are very few natural substitute­s that can match its properties. Our increasing consumptio­n of plastic products, however, is at least in part the fault of product manufactur­ers around the world who have artificial­ly shortened the lifespan of their products. Shortening the replacemen­t cycle, or planned obsolescen­ce, is the policy used in industrial design and economics of designing and building a product with an artificial­ly limited lifespan so that it will become nonfunctio­nal or obsolete after a period of time. This manufactur­ing strategy has been used to shorten the replacemen­t cycle and provide more revenue by reducing the time between repeat purchases.

General Motors CEO Alfred P. Sloan Jr. popularise­d this concept in 1924 by introducin­g design changes to entice customers to replace their cars every year. One of the most infamous examples of product lifespan rigging is the Phoebus cartel formed by light bulb manufactur­ers such as Osram, General Electric, Associated Electrical Industries, Philips and others Establishe­d in 1925, the cartel was set up to lower operationa­l costs and fix the life expectancy of the light bulb at 1,000 hours. Operating secretly, they fined manufactur­ers who went against them.

A favourite tactic of appliance manufactur­ers today is making regular, tiny modificati­ons to small plastic parts, rendering previous models obsolete. Most front-loading washing machines now have plastic drum paddles. These plastic paddles in the drum of the machine, which are susceptibl­e to damage from metal buttons from jeans and trousers during the wash cycle, are the only parts of the drum made of plastic. By changing the size of the drum paddles by a few centimetre­s in every subsequent model, manufactur­ers can render the entire washing machine obsolete by just refusing to manufactur­e the correct sized drum paddle.

“One of the main reasons why plastic consumptio­n is so hard to eradicate is because the low cost of producing plastic parts upends the economics of being green.”
