14,450 Tonnes a Day: The Plastic Crisis Burying the Himalayas

At Pangong Lake, one of the most photographed landscapes on earth, 300 to 600 vehicles arrive every day and leave their waste behind. It is a miniature of a regional catastrophe that no one is managing.

The road to Pangong Tso climbs through the Chang La pass at 17,590 feet and drops into a valley so still that the lake appears to have been painted onto the earth. The water is a saturating blue, the kind that collapses the distance between camera and subject and has turned this stretch of eastern Ladakh into one of the most Instagrammed landscapes in Asia. Three hundred to six hundred vehicles make the trip daily during the tourist season. They bring sandwiches in multilayered plastic pouches, chips in metallised film bags, energy drinks in PET bottles, and biscuits in polypropylene wrappers. They leave most of it behind.

Along the southern shore, where the most popular photo spots cluster, wind-blown chip packets accumulate in the gaps between rocks. Lay's. Kurkure. Sting Energy. The brands are legible from a distance. Volunteers who participated in the Himalayan Cleanup 2024 recorded what they found: 84.2 percent of all plastic waste at surveyed sites across the Indian Himalayan Region was food and drink packaging. Not construction debris, not agricultural film, not medical waste. Snack wrappers and beverage containers.

Pangong Lake is not an outlier. It is a sample.

The numbers no one planned for

The Indian Himalayan Region -- stretching across twelve states and union territories from Jammu & Kashmir to the northeast -- generates an estimated 14,450 tonnes of solid waste every day, according to figures compiled by NITI Aayog and the World Bank. To visualise the quantity: it is roughly the weight of 2,400 adult Asian elephants, dumped across mountain ecosystems every twenty-four hours.

That number has approximately doubled in the last decade, driven almost entirely by tourism. Uttarakhand and Himachal Pradesh alone have received more than 400 million tourists since 2010. Ladakh, which had negligible tourist infrastructure fifteen years ago, recorded over 525,000 visitors in 2023. In Leh town alone, the daily discard rate during peak season exceeds 50,000 plastic bottles.

The waste is not just voluminous. It is the wrong kind. The Himalayan Cleanup 2024 -- an annual audit conducted by over 15,000 volunteers across more than 450 sites -- found that 71 percent of all plastic waste collected was non-recyclable multilayered plastic (MLP). These are the metallised films used in chip packets, the laminated sachets used for shampoo and gutka, the composite pouches used for instant noodles. They cannot be mechanically recycled. No informal waste picker has an economic reason to collect them. They have no second life in the current Indian waste economy.

This is the structural fact that makes the Himalayan plastic waste crisis different from, say, urban municipal waste in Delhi or Mumbai. In a city, PET bottles and HDPE containers have scrap value. Waste pickers sort them, aggregators buy them, recyclers process them. The informal economy handles a significant fraction of recyclable urban waste. In the mountains, the calculus breaks. The distances are too great, the volumes per settlement too small, and the dominant waste category -- MLP -- is economically worthless. The result is accumulation without exit.

Naming the brands

For three consecutive years, the Himalayan Cleanup's brand audit has identified PepsiCo as the single largest corporate contributor to plastic pollution across the Indian Himalayan Region. Its products -- Lay's, Kurkure, Doritos, and the energy drink Sting -- appear at every surveyed site in quantities that dwarf any other manufacturer. Coca-Cola consistently ranks second.

This is not an activist's accusation. It is a counting exercise. Volunteers photograph, sort, and log the brand name on every legible piece of packaging they collect. The methodology is adapted from the Break Free From Plastic global brand audit, which has identified the same companies as top polluters worldwide for six years running.

The finding matters because it shifts the conversation from consumer behaviour to producer responsibility. Indian law, through the Plastic Waste Management Rules of 2016 and their subsequent amendments, mandates Extended Producer Responsibility (EPR) for companies whose products generate plastic waste. Under EPR, PepsiCo, Coca-Cola, and every other FMCG company selling packaged goods in the Himalayan region are legally obligated to collect and process an equivalent quantity of plastic waste.

In practice, EPR enforcement in the Himalayas is non-existent.

In July 2025, the Ladakh Autonomous Hill Development Council (LAHDC) in Leh took the unusual step of issuing formal warnings to both Coca-Cola and PepsiCo for failing to meet their EPR obligations in the union territory. The companies had been selling products in Ladakh for years without establishing any collection or recycling infrastructure. The warnings were reported in local media but produced no visible change in operations.

Himachal Pradesh went further. On June 1, 2025, the state government banned the sale of single-use plastic water bottles below one litre. The ban was a direct response to the waste crisis in tourist corridors -- Shimla, Manali, Dharamshala, and the highways feeding them. Early reports suggest mixed enforcement: the ban holds in urban centres where municipal police can monitor retail outlets, but collapses on highways and in remote areas where there is no inspection capacity.

Neither measure addresses the fundamental problem: multilayered plastic, which constitutes the majority of the waste stream, is not covered by deposit return schemes, is not collected by any formal or informal system, and has no recycling pathway at any scale in India.

Darjeeling: a case study in systemic failure

Darjeeling, the hill station in northern West Bengal that draws its fame from tea estates and a view of Kangchenjunga, generates between 30 and 45 metric tonnes of solid waste per day. The volume fluctuates with tourist season, peaking during the Durga Puja holidays and the spring bloom.

The town has no waste treatment facility. None. Not a composting unit, not a material recovery facility, not a sanitary landfill. Every tonne of waste generated in Darjeeling is loaded onto trucks and driven more than fifty kilometres downhill to Siliguri, the plains city at the base of the hills.

Siliguri, in turn, is drowning. The city of roughly 800,000 people generates 360 tonnes of waste daily. Eighty-three percent of it is open dumped, according to municipal records. The primary dumping ground, located on the banks of the Mahananda River, has been in continuous use since 1949. It is not a landfill by any engineering definition. It is a heap, subject to flooding during monsoon, leaching into the river year-round, and receiving Darjeeling's waste on top of its own.

The situation in Darjeeling is not a result of negligence by any single municipal official. It is a result of geography and economics. Building waste processing infrastructure in the mountains is expensive. Land is scarce and contested. The engineering requirements for a sanitary landfill on a steep gradient are an order of magnitude more complex than on the plains. And the revenue base of a hill municipality -- dependent on property taxes from a small population -- cannot fund capital-intensive infrastructure.

But neither the state government of West Bengal nor the central government has stepped in with dedicated funding. The Swachh Bharat Mission, India's flagship sanitation programme, has disbursed crores for toilet construction in hill regions but has not financed a single integrated waste management facility in Darjeeling.

The result is a sixty-year-old open dump on a riverbank, growing by 360 tonnes a day, serving as the terminal point for waste from an entire mountain district.

The glaciers are already contaminated

The waste crisis is no longer limited to roadsides and tourist spots. It has reached the ice.

Multiple peer-reviewed studies published between 2020 and 2025 have documented the presence of microplastics in Himalayan glaciers, including glaciers in the Everest region and in the Indian states of Uttarakhand and Himachal Pradesh. The particles -- fragments of polyethylene, polypropylene, and polyester, most smaller than five millimetres -- are transported by wind from lower elevations, deposited on snow and ice surfaces, and incorporated into glacial mass over successive seasons.

The contamination is not merely symbolic. Dark-coloured microplastic particles reduce the albedo -- the reflectivity -- of snow and ice surfaces. Lower albedo means more solar energy is absorbed rather than reflected. More absorbed energy means faster melting. Researchers studying glaciers in the Alps and the Arctic have quantified this effect: microplastic contamination, combined with black carbon and mineral dust, measurably accelerates glacial retreat.

In the Himalayas, this carries a downstream consequence of civilisational scale. The glaciers of the Greater Himalayan range feed the Ganges, the Indus, the Brahmaputra, and their tributaries. These rivers supply water to roughly 1.5 billion people. Microplastics embedded in glacial ice will enter the meltwater. They are already entering the meltwater. A 2023 study found microplastic concentrations in the upper Ganges at Rishikesh -- still within the mountain stretch of the river -- at levels comparable to urbanised river stretches downstream.

The Himalayan plastic waste crisis is not, in other words, a problem of littering. It is a problem of source water contamination for the most densely populated river basin on earth.

What has been tried

Against this backdrop, a handful of organisations have been building alternatives with minimal resources and no policy support.

In Darjeeling, the Zero-Waste Andolan -- a citizens' initiative that grew out of frustration with municipal inaction -- has converted three villages in the district to zero-waste status. The model is labour-intensive but functional. Households segregate waste into as many as 53 categories at a community-run Material Recovery Facility (MRF). Organic waste is composted. Recyclables are aggregated and sold. Non-recyclable MLP is stored, compressed into bales, and sent to cement kilns for co-processing -- the only currently viable disposal route for multilayered plastic in India.

The Andolan's three villages prove the concept. They also illustrate the scale problem. Darjeeling district has over 840 villages and a dozen urban wards. The Zero-Waste Andolan, funded primarily by donations, cannot replicate itself across the district without institutional support that has not arrived.

Waste Warriors Society, founded twelve years ago, now operates in more than ten locations across Himachal Pradesh, Uttarakhand, and Ladakh with over 200 employees. They run waste collection and segregation programmes in towns that lack municipal capacity -- McLeod Ganj, Bir, Spiti Valley, and sections of Leh. Their model integrates informal waste workers into a formal collection system, pays them regular wages, and processes recyclables through their own MRFs.

Waste Warriors has demonstrated that systematic waste management is possible in mountain towns. But like the Zero-Waste Andolan, they operate on grants, donations, and CSR funding. Their annual budget is a fraction of what a single FMCG company spends on advertising in the region where its packaging ends up as waste.

What works elsewhere

India is not the first country to confront waste management in mountain environments. The solutions that have worked elsewhere share a common structure: they make the producer or the consumer pay at the point of sale, and they create an economic incentive for return.

Nepal's Sagarmatha (Everest) region has operated a deposit system for mountaineering expeditions since 2014. Every summiteer pays a deposit of $4,000, refunded only upon return with at least eight kilogrammes of waste. The system has removed tonnes of accumulated garbage from the mountain's upper camps. It works because the enforcement point is narrow -- there is a single permit office -- and because the deposit is large enough to change behaviour.

Bhutan, India's neighbour to the east, has committed to a national Zero Waste by 2030 goal. The country's small population and strong central governance make enforcement feasible in ways that may not translate to Indian federalism, but the policy signal is clear: waste in mountain ecosystems is treated as a first-order environmental threat, not an afterthought of tourism promotion.

Switzerland, a useful comparison because of its alpine geography and its tourism volumes, recycles 80 percent of its PET bottles -- without a mandatory deposit return scheme. The system relies on a voluntary industry agreement backed by the implicit threat of legislation. Retailers host collection points. A dedicated logistics network handles reverse transport from mountain valleys to lowland recycling facilities. The key feature is that the cost of collection and recycling is built into the product price. Swiss consumers pay roughly two centimes per bottle into the recycling fund. The system is invisible at the point of purchase and near-total in its coverage.

India has none of these mechanisms operating in the Himalayan region. There is no deposit return scheme for any packaging type. EPR obligations exist on paper but are not enforced in any mountain state or union territory. There is no reverse logistics network for packaging waste. The cost of waste management is borne entirely by municipalities that lack the revenue to manage it, by NGOs that lack the scale, and by ecosystems that lack a voice.

What it would take

The arithmetic of the crisis is not complicated. The Indian Himalayan Region needs three things, and it needs them simultaneously.

First, a deposit return scheme for beverage containers, operational across all twelve Himalayan states and union territories. The design is well understood. A deposit of two to five rupees per bottle or can, collected at point of sale and refunded at automated collection points, would create an economic incentive for return and a revenue stream for collection infrastructure. Multiple countries have demonstrated that deposit return schemes achieve collection rates above 90 percent within three years of implementation. India's FMCG lobby has resisted such a scheme nationally for a decade. The Himalayan states could implement it regionally if they chose to -- Himachal Pradesh's plastic bottle ban demonstrates the political will exists. A deposit return scheme would be more effective and less economically disruptive than an outright ban.

Second, enforced EPR with teeth. The Central Pollution Control Board must audit EPR compliance by brand and by geography. Companies selling packaged goods in the Himalayas must be required to fund collection and processing infrastructure proportional to their sales volume in the region. Non-compliance should result in sales bans, not warnings. The LAHDC Leh warning to Coca-Cola and PepsiCo in July 2025 was a start. It should be the template, not the exception.

Third, dedicated central funding for mountain waste infrastructure. The Swachh Bharat Mission's next phase must include a Himalayan component that accounts for the higher per-capita cost of waste management in mountain geographies. This means MRFs in every district headquarters, composting facilities in every block, and engineered sanitary landfills -- or, better, waste-to-energy or co-processing arrangements -- that eliminate the need to truck waste to plains cities. The alternative is the Siliguri model: mountain waste piled on riverbanks, leaching into the water supply of the Indo-Gangetic plain.

None of this is technologically novel. None of it requires innovation. It requires expenditure, enforcement, and the political recognition that the mountains are not a dumping ground with a view.

The weight of inaction

The 14,450 tonnes generated today will be generated again tomorrow. And the day after. The tourists will keep coming -- India's domestic tourism is growing at 15 to 20 percent annually, and every state tourism board in the Himalayan region is spending money to accelerate that growth. Every new hotel, every new road, every new Instagram post of Pangong Lake or Rohtang Pass or Valley of Flowers is a vector for more packaging waste entering an ecosystem with no capacity to handle it.

The Himalayas are not resilient to this. They are not a forest that regenerates after a fire. Glaciers contaminated with microplastics do not clean themselves. Rivers carrying plastic fragments from 4,000 metres do not filter themselves. Soil in alpine meadows where MLP fragments have been trodden into the earth does not recover on human timescales.

PepsiCo's 2025 annual report describes the company's commitment to "a world where packaging never becomes waste." In the Indian Himalayan Region, where its branded packaging is the single most commonly found item of plastic litter for the third consecutive year, that sentence reads less like a commitment and more like a punchline.

The question is not whether the Himalayas have a plastic waste crisis. The data settled that years ago. The question is whether anyone with the authority and the budget to act will do so before the damage becomes irreversible -- or whether the mountains will continue to serve as both India's most marketed landscape and its most neglected dumping ground.

At Pangong Lake, the water is still blue. The chip packets are still legible. The trucks are still climbing the pass.
