From PVC to LDPE: The Plastics Hidden in Everyday Life

From packaging to household goods, RIC 3 and 4 plastics are everywhere. Learn how to identify them at a glance. Dear Reader,In my previous article, we explored the first two Resin Identification Codes— RIC 1 (PET) , commonly used in beverage and food containers, and  RIC 2 (HDPE) , found in sturdy household bottles and a wide range of utility products. Both plastics are among the easiest to recycle, making them central to responsible waste management and to the broader shift towards more sustainable patterns of consumption. With this foundation in place and a clearer understanding of how these codes guide our daily choices, let us now move on to the remaining classifications in the Resin Identification System and understand what each one signifies. Code 3: PVC (Polyvinyl Chloride) Code 3 refers to products made from polyvinyl chloride, or PVC—a remarkably versatile and inexpensive plastic valued for its durability, water resistance, and excellent electrical insulation. As the world’s third most produced plastic, PVC is manufactured in both rigid and flexible forms, each designed to meet a wide array of everyday needs. Flexible PVC, produced using plasticisers, appears in raincoats, boots, shower curtains, handbags, and imitation leather upholstery. It is also used in bottles for non-food items such as shampoos and cosmetics, in clear blister packaging for medicines, and in cling film that helps preserve the freshness and quality of food. Rigid PVC, prized for its strength and longevity, is used to manufacture credit cards, debit cards, national identity cards, and various inflatable items—from pool toys and floats to air mattresses. It is also present in yoga mats, sports equipment, and numerous DIY and craft materials that require durability and ease of handling. One of the most significant industrial uses of PVC is in piping. Rigid PVC pipes have increasingly replaced metal pipes in water supply, sewage, and drainage systems due to their resistance to corrosion, leakage, and environmental wear. Unplasticised PVC (uPVC) is widely used for window and door frames, offering excellent insulation, weather resistance, and minimal maintenance requirements. Vinyl flooring—produced as tiles, sheets, or planks—is another major PVC-based product, valued in homes, offices, and hospitals for its durability, affordability, and ease of cleaning. PVC’s strong insulating properties also make it ideal for coating electrical wires and cables, while PVC membranes and siding provide long-lasting, weather-resistant coverings for roofs and exterior walls. Although PVC can be recycled, the process is considerably more complex than with many other plastics. The numerous additives used to improve its flexibility, strength, and stability often interfere with the recycling process and can reduce the quality of the recycled material, limiting its suitability for certain applications. Code 4: LDPE (Low-Density Polyethylene) Code 4 identifies products made from low-density polyethylene, or LDPE—one of the most widely used plastics thanks to its lightness, flexibility, and overall durability. LDPE is commonly found in stretchable grocery bags, shopping bags, and general-purpose garbage bags. It is also extensively used in milk pouches, bread and frozen-food packaging, cling film, snack and toiletry pouches, and other everyday wrapping materials. Many squeeze bottles for glue, paints, condiments, and household liquids are made from LDPE, as are numerous lids and caps. Additionally, LDPE forms the waterproof inner lining of juice and milk cartons, helping protect the contents and extend shelf life. Beyond packaging, LDPE serves as a protective coating in various products, appears in trash-can liners, and is widely used in children’s toys such as buckets and play balls due to its resilience and safety profile. Some household goods—including certain cutting boards—are also manufactured from LDPE, benefiting from its strength and ease of cleaning. Despite its versatility and widespread use, LDPE poses notable challenges for recycling. Rigid LDPE products are somewhat easier to process, but thin bags, wraps, and cling films are difficult to collect, separate, and recycle efficiently. As a result, a significant proportion of these items unfortunately ends up in landfill. Our discussion will continue in next week’s instalment, where we will explore the remaining Resin Identification Codes in greater depth and understand how they influence recycling practices. Until then, I wish you a pleasant and enjoyable weekend.   (The author is an environmentalist. Views personal.)

Fatal Friendships: The U.S., Ukraine and the Limits of American Loyalty

Updated: Mar 4

The unsavoury diplomatic row between Zelenskyy and Trump was a reminder for the world that U.S. foreign policy remains as transactional as ever.

Zelenskyy and Trump

Henry Kissinger once remarked that being America’s enemy is dangerous, but being its friend is fatal. Ukraine, like so many before it, is learning this the hard way.


If there is a moment that encapsulates the fickleness of American foreign policy, it is the latest diplomatic spat between President Trump, Vice President J.D. Vance and Ukrainian President Volodymyr Zelenskyy during the latter’s visit to the Oval Office. The once-celebrated wartime leader, who was paraded across Washington as a symbol of democratic resilience, now finds himself cast aside like so many other American allies before him. The drama played out in full view of the world, with Trump and Vance publicly dressing down Zelenskyy, demanding gratitude, and pressing for long-term access to Ukraine’s natural resources in exchange for continued support. For Zelenskyy, this was a humiliating moment; for the world, it was a reminder that U.S. foreign policy remains as transactional as ever.


To anyone familiar with American diplomacy, this episode was hardly surprising. The United States has a long history of intervening in the affairs of other nations, often in pursuit of its own strategic interests. Between the 1848 annexation of Mexico and the countless regime-change operations of the Cold War, Washington has prided itself on shaping global politics to its advantage. Now, Ukraine finds itself on the receiving end of this history, left to reckon with the harsh reality that the U.S. does not sustain friendships but exploits them.


To understand how Ukraine arrived at this precarious juncture, one must rewind to the 1990s, when the seeds of today’s conflict were sown. In 1990, as the Soviet Union crumbled, a tacit agreement was made between President George H.W. Bush and Soviet leader Mikhail Gorbachev: NATO would not expand eastward. That promise was swiftly broken. Nineteen times, the U.S. welcomed former Soviet states into NATO, tightening the noose around Russia’s sphere of influence. Moscow protested, but its grievances fell on deaf ears until Ukraine became the next domino.


By 2014, tensions boiled over. In what became known as the Revolution of Dignity, Ukraine’s pro-Russian president, Viktor Yanukovych, was ousted in a U.S.-backed uprising. Western leaders celebrated this as a victory for democracy, but to Moscow, it was yet another American betrayal. Russia responded by annexing Crimea, an act widely condemned but entirely predictable. What followed was a drawn-out war in Ukraine’s eastern provinces, with separatist groups in Donetsk and Luhansk declaring independence - moves backed by the Kremlin.


Even then, there remained a narrow path to peace. Russia had no objections to Ukraine joining the European Economic Community; its red line was NATO membership. A grand diplomatic bargain was possible, one in which Ukraine could integrate with the West economically while remaining militarily neutral. But American policymakers, eager to consolidate Ukraine as a client state, rejected such an approach. They doubled down on military aid and encouraged Zelenskyy to pursue NATO ambitions, despite Russia’s clear warnings that this would provoke war.


By 2022, the inevitable happened: Russia invaded Ukraine. Washington responded with sanctions, weapons shipments, and financial aid packages that, while substantial, were not entirely altruistic. The U.S. supplied Ukraine with arms, but these weapons were purchased from American manufacturers, ensuring billions of dollars flowed back into the U.S. economy. The Biden administration painted its support as a moral crusade, yet in reality, it was a profitable venture wrapped in the language of democracy.


Enter Trump, back in the White House, bringing his characteristic disdain for multilateralism. While Biden had embraced Ukraine as a moral cause, Trump sees it as a business transaction. Zelenskyy’s recent visit to Washington underscored this shift. Far from being welcomed as a heroic figure, he was reprimanded like an ungrateful client. Trump and Vance not only questioned the extent of U.S. aid citing a wildly inflated figure of $300 billion, when in reality, the Kiel Institute places it at $119.7 billion but also demanded that Ukraine reward American generosity with long-term contracts granting U.S. firms access to its valuable mineral resources.


For Zelenskyy, the humiliation was complete when the U.S. refused to offer Ukraine any security guarantees. The man who once stood before Congress to thunderous applause was now walking away from meetings empty-handed. If there was any lingering doubt about the transactional nature of America’s commitment, it had been dispelled.


Predictably, this diplomatic fiasco has deepened divisions within the Western alliance. European leaders, already sceptical of Trump’s foreign policy instincts, have openly criticized the U.S. for its heavy-handed treatment of Ukraine. Meanwhile, Russia is watching closely, sensing an opportunity to exploit the cracks in Western unity. Moscow does not need to defeat Ukraine on the battlefield if it can win the war by eroding international support for Kyiv.


Ukraine’s predicament raises a larger question: What does it mean to be America’s ally in the 21st century? The answer, it seems, is that alliances with Washington come with an expiration date. Today, Ukraine faces the same fate as past U.S. partners - betrayed, abandoned and left to navigate a crisis alone.


Perhaps Zelenskyy should have taken Kissinger’s warning to heart: America’s enemies may suffer, but its friends are doomed.
