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.)

A Bitter Harvest: Poverty and Promise in Assam’s Tea Gardens

Updated: Jan 23

Assam’s Tea Gardens

India’s Northeast, often referred to as the ‘rainbow country,’ is a captivating paradox. It brims with natural beauty, rich biodiversity and a mosaic of cultures yet persistent underdevelopment paints a troubling picture of neglect and missed opportunities. To state the obvious, this region, bordered by five countries—Bangladesh, Bhutan, China, Myanmar, and Nepal—stands as a geopolitical linchpin for India’s security and diplomacy. The culturally diverse ‘Seven Sisters’ region is a treasure trove of resources, enriched by rivers that sustain unique ecosystems. Regrettably, its potential remains stunted by historical isolation, inadequate infrastructure and a deep-seated frustration stemming from poor governance.


Historical Isolation

Connectivity—or the lack thereof—has been a defining issue for the Northeast. A staggering percent of its borders adjoin other countries, rendering it dependent on tenuous land corridors for trade, healthcare, and mobility. This has hindered private investment, exacerbated economic disparities and fuelled the region’s reliance on central government funds.


An uneven distribution of these funds further deepens the divide. Consider Assam, the region’s most populous state. With a population of 3.58 crore as of 2023, Assam accounts for 64 percent of the Northeast’s inhabitants. Yet, its per capita allocation of central funds trails behind other states. For instance, in the 2022–23 financial year, Assam received approximately Rs. 31,253 crore, while the remaining seven states, with just 36 percent of the region’s population, collectively garnered Rs. 37,600 crore. Such disparity undermines developmental efforts in Assam, especially for its most vulnerable communities.


Within Assam, stark inequities persist. While 2.38 crore people reside in cities and towns with relatively better access to education and healthcare, about 1.2 crore people live in abject conditions. Among them are tea garden workers, or Sadanis, descendants of labourers brought to Assam by the British from states like Maharashtra, Madhya Pradesh and Bihar.


Confined to remote tea estates in districts like Lakhimpur, these workers endure squalid living conditions, minimal healthcare, and limited access to education. The average life expectancy among tea workers is a dismal 50 years—18 years below the national average. Malnutrition, alcoholism and generational poverty plague these communities, perpetuating cycles of marginalization and unrest.


The plight of tea workers is emblematic of the Northeast’s broader challenges. Despite their historic loyalty to India, these communities have remained on the fringes of development. Their struggles reflect not only economic neglect but also a failure to integrate their narratives into the mainstream discourse.


The Assam government has initiated measures to uplift its underprivileged populations, but these efforts remain piecemeal. Without a holistic strategy to address structural inequalities, the region risks further alienation. Delays in improving living standards not only harm the marginalized but also jeopardize India’s national security.


Grassroots efforts provide a glimmer of hope. One such laudable effort is that of the Bhaskar Sanskar Kendra, a self-funded unit of the Utthan Charitable Foundation which is an exemplar of what community-led interventions can achieve. Based in Parbatipur No. 2, the Kendra has been working tirelessly since 1988 to improve education, empower youth, and uplift women in tea garden communities.


Run by Ashok and Alka Varnekar, the Kendra’s initiatives are driven by passion and commitment. Their efforts recently earned them the Sewa Gurav Puraskar from the Pune-based Natu Foundation. Yet, much more is needed in the form of volunteers, donations and systemic support to scale such interventions and achieve meaningful change.


Beyond Charity

The story of Assam’s tea workers is not just one of charity but of strategic importance. The Northeast serves as India’s gateway to Southeast Asia, a region crucial to New Delhi’s Act East Policy. Neglecting the region’s socioeconomic fabric risks exacerbating insurgencies and undermining national security.


Empowering marginalized communities is a moral imperative, but also a strategic one. A well-developed Northeast can serve as a bulwark against external threats, foster regional trade and reinforce India’s cultural and geopolitical ties with its neighbours.


The path forward requires a multi-pronged approach. First, the central and state governments must prioritize equitable fund allocation, ensuring that populous states like Assam receive their fair share. Second, targeted programs must address the specific needs of marginalized groups, such as tea garden workers, through better healthcare, education, and economic opportunities.


Third, private investment must be encouraged. By improving connectivity and creating business-friendly environments, the region can attract industries that generate employment and foster local entrepreneurship. Finally, grassroots organizations need greater recognition and support, as they serve as critical bridges between government initiatives and community needs.


The Northeast has long been viewed through the prism of its challenges rather than its potential. It is time to change that narrative. Recognizing the region’s strategic importance, celebrating its cultural diversity, and addressing its systemic inequalities are steps toward a more inclusive and secure India.


For the tea workers of Assam and countless others who endure hardship in silence, development is a necessity. Their future is India’s future, and it is high time we act with the urgency and commitment that this region deserves.
