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.)

The Brewing Tempest: India’s Looming Multi-Front Challenge

India’s Looming Multi-Front Challenge

In the annals of India’s strategic concerns, the notion of a multi-front war has always loomed as a theoretical worst-case scenario. Today, it seems less theoretical and more a stark possibility. India now finds itself in a precarious position, navigating strained relations with China, Pakistan, and Bangladesh, while domestic turbulence threatens to undermine its internal stability. The prospect of a ‘three-and-a-half-front war’ has moved from the realm of policy seminars to the reality of national security briefings.


India’s immediate worry lies to the east, where its relationship with Bangladesh has taken a sharp and disconcerting turn. The August 2024 U.S.-backed ousting of Sheikh Hasina from power was a watershed moment. Using student protests as cover, a democratically elected government was replaced with one led by the Nobel laureate Mohammad Yunus. While Yunus’s credentials may shine abroad, his ascent has sown discord at home and abroad. Sheikh Hasina, now in exile in India, remains a polarizing figure—a living symbol of a broken democratic covenant in Dhaka.


Under Yunus’s interim administration, Bangladesh has adopted policies that cut deeply into the ties that once bound the two nations. Trade restrictions have bruised Indian industries. Dhaka’s narrative, now laced with accusations of Indian interference, disregards India’s critical role in Bangladesh’s independence in 1971. To further exacerbate tensions, the new regime has demanded Hasina’s extradition, a move calculated to inflame bilateral relations.


Adding a troubling dimension to the equation is Bangladesh’s evolving military posture, supported by a trio of regional players—China, Pakistan, and Turkey. Beijing is readying supplies of advanced fighter jets and attack helicopters. Islamabad has offered training for Bangladeshi forces, while Ankara has provided drones and missile systems, with promises of more. These developments are no mere armoury upgrades but signal the creation of a strategically fortified Bangladesh, potentially aligned with adversarial forces.


But it is not just external threats that keep Indian strategists awake at night. The ‘half front’ is a vexing and amorphous challenge rooted in the nation’s domestic fissures.


India’s internal security apparatus faces mounting pressure from cross-border terrorism, much of it orchestrated by Pakistan’s Inter-Services Intelligence (ISI). Recent investigations into unrest in Manipur have revealed links to Arakan and Chin insurgent groups. Refugee influxes, particularly from Bangladesh, have brought with them not only humanitarian challenges but also security risks, with reports of terror plots linked to some of these migrants. Foreign-funded civil society organizations, while vital to democracies, have been accused of advancing anti-national agendas, channelling resources into protests, propaganda, and even electoral interference.


The economic dimension of the ‘half front’ is equally troubling. China’s economic encirclement of India has shifted from borders to boardrooms. By dumping cheap goods into the Indian market and leveraging opaque collaborations with domestic companies, Beijing continues to destabilize local industries. The $4 billion Chinese investment in Indian startups, once seen as a sign of bilateral economic integration, now appears as a potential Trojan horse.


On top of these challenges are the festering domestic grievances that simmer across India’s social and political landscape. From ethnic tensions and agrarian distress to religious discord and the proliferation of drugs, these issues create fertile ground for unrest.


So, how does India chart a course through this storm? The first step lies in diplomacy. India must recalibrate its foreign policy to counter the growing nexus of China, Pakistan, and Bangladesh. Strengthening ties with countries like Japan, Australia, and the United States will be crucial. Multilateral forums, such as the Quad, offer platforms for India to project influence and build strategic deterrence.


Modernizing the armed forces and intelligence apparatus is another urgent priority. While India’s military remains a formidable force, the threats it faces are evolving rapidly. Cybersecurity, unmanned systems, and artificial intelligence must take centre stage in defence planning. Border infrastructure, often overlooked in times of peace, must be bolstered to ensure rapid mobilization and supply chain resilience.


Domestically, the government must eradicate corruption in security, tackle root causes of unrest with equitable economic reforms, counter radicalization through education, and foster unity with targeted community outreach.


Civil society, too, has a role to play. Instead of vilifying these organizations wholesale, the government should work with credible groups to foster a sense of shared purpose and responsibility. A vigilant citizenry, armed with critical thinking and media literacy, can act as a bulwark against the tide of disinformation.


Finally, India must recognize the delicate balance between strength and restraint. To quote Sun Tzu from The Art of War: “In the midst of chaos, there is also opportunity.” The chaos India faces today is undeniable, but so, too, is the opportunity—to redefine its security paradigm, to reinvigorate its democratic institutions and reaffirm its role as a stabilizing force in a volatile region.


The stakes could not be higher. India’s ability to navigate this tempest will determine not only its own future but also the trajectory of an entire region. As history has shown, nations that weather their storms often emerge stronger, tempered by adversity and fortified by resolve. For India, the time to act is now.
