Agricultural plastic pollution is a growing crisis affecting soil health, ecosystems, and farming sustainability worldwide. In 2019, agriculture used 12.5 million tonnes of plastic, with less than 10% recycled. These plastics, including mulch films, irrigation tubing, and seed coatings, often remain in the soil, breaking down into harmful micro- and nanoplastics. By 2030, emissions from agricultural plastics could reach 47 million tonnes of CO₂-equivalent, doubling by 2050.
Key regional insights:
Asia: The largest consumer, especially China, uses plastic film mulching to boost yields but struggles with waste mismanagement.
Europe: Focuses on recycling and stricter regulations, but soil contamination from microplastics persists.
North America: Faces severe microplastic accumulation in soils, with low recycling rates and harmful disposal practices.
Latin America & Africa: Depend on plastics for productivity but lack proper waste systems, leading to open burning and soil degradation.
Global solutions are emerging, such as biodegradable alternatives, lifecycle tracking, and regulatory initiatives like the FAO's 2025 Voluntary Code of Conduct. However, balancing productivity with long-term soil and ecosystem health remains a challenge.
1. Asia
Plastic Usage
Asia stands out as the largest consumer of agricultural plastics globally, with China taking the lead as both the top producer and user of these materials. One of the most transformative practices in the region is plastic film mulching (PFM), particularly in arid and semi-arid areas. In China, around 18 million hectares of farmland are covered with plastic film annually [4], accounting for about 13% of the nation's cultivated land [6].
PFM delivers impressive results: it boosts crop yields by 45.5%, enhances water use efficiency by 58.0%, and reduces weed growth by 95% [4]. In 2012 alone, this technique contributed to the production of an additional 30 million tonnes of wheat, maize, and rice - enough to feed an extra 85 million people [4]. Beyond mulching, Asian agriculture relies heavily on plastic-based solutions like greenhouse covers, polytunnels, irrigation tubes, and microplastics added to fertilisers, pesticides, and seeds to regulate release rates.
Waste Mismanagement
While these plastics drive agricultural productivity, poor disposal practices undermine their benefits. Across Asia, improper handling of plastic waste has led to widespread soil contamination. Practices such as open burning or burying plastics directly in fields cause these materials to break down into microscopic particles.
In 2025, a trial in Lanzhou Province, China, introduced an innovative solution: QR codes printed on agricultural films during manufacturing. These codes allowed the tracking of plastics throughout their lifecycle - from production to field use and eventual disposal - ensuring accountability and reducing soil leakage [4]. However, such systems are still not widely adopted, and biodegradable alternatives remain costly, priced at 2–3 times more than traditional low-density polyethylene films [4]. This gap in management has severe consequences for the environment.
Environmental and Soil Impacts
The long-term accumulation of plastics threatens to reverse the productivity gains that initially made them appealing. Over time, weathering breaks plastics down into secondary micro- and nanoplastics. Particles smaller than 1 μm can behave like colloids, making it easier for them to infiltrate the food chain. Interestingly, even in Northwest China - where PFM use is widespread - soil microplastic levels remain relatively low, suggesting that atmospheric deposition and irrigation also play a significant role in contamination [4].
"The build-up of plastic can have wide-ranging impacts on soil health, biodiversity and productivity, all of which are vital for food security." – Professor Elaine Baker, University of Sydney [5]
2. Europe
Plastic Usage
Europe consumes a staggering 56.5 million tonnes of plastic each year, which breaks down to an average of 107 kg per person. Packaging and construction dominate plastic usage, with agriculture following behind [8]. However, the demand for agricultural plastics, such as greenhouse, mulching, and silage films, is projected to rise sharply. From 2018 to 2030, this demand is expected to grow by 50%, increasing from 6.1 million tonnes to 9.5 million tonnes [7]. This surge in usage is directly tied to growing concerns about soil pollution.
Environmental and Soil Impacts
The widespread use of plastics in agriculture has led to a persistent build-up of micro- and nano-plastics in soils [9]. Beyond direct plastic application, contamination also stems from other sources like organic fertilisers (e.g., sewage sludge and compost) and even atmospheric deposition [9]. These tiny plastic particles disrupt crucial soil properties, alter water retention and flow, and negatively impact soil microbiota. Invertebrates, such as earthworms, are also affected, further disrupting the ecosystem [9].
The PAPILLONS project, which wrapped up in April 2025, shed significant light on this issue. Over four years, the project brought together 20 partners from 12 countries to conduct a comprehensive survey of microplastic levels in agricultural soils across 70 sites in seven European countries. The findings were presented at the AGRIFOODPLAST conference in Brussels and played a key role in shaping the upcoming EU soil monitoring law, which will now include microplastic levels as a soil health criterion [9]. A warning from the project’s report highlighted the gravity of the situation:
"Negative effects can already be seen at concentration levels that are not uncommon in European soils, ringing an alarm bell" [9].
Plastic pollution also varies across European waters. The Mediterranean and Black Seas are particularly affected, showing higher litter concentrations compared to the North-East Atlantic and Baltic Seas [8]. In 2019 alone, between 0.7 million and 1.8 million tonnes of microplastics were released within the EU [8]. Even biodegradable plastics, often seen as a solution, may linger in Europe’s cooler climates [9].
3. North America
Plastic Usage
In North America, agriculture relies heavily on plastics like polyethylene (PE), polystyrene (PS), polyethylene terephthalate (PET), and polyester (PLY). These materials are used in a variety of applications, such as mulch films, seedling trays, irrigation tubing, livestock feed bags, and greenhouse covers, among others [1][5]. Additionally, farmers use microplastics as coatings for fertilisers, pesticides, and seeds to improve nutrient absorption [1][5]. While the region’s use of plastic mulch films is lower - averaging 10–20 kg per hectare compared to Europe and Asia’s 40–50 kg per hectare [2] - these plastics have become a significant contributor to microplastic accumulation in North American soils.
Microplastic Growth
Shockingly, North American soils contain nearly 23 times more microplastics than the world’s oceans [10]. The density of these particles varies widely, ranging from a few hundred particles per kilogramme in rural areas to over 200,000 particles per kilogramme in areas of intensive use [10]. Joseph Boctor, a PhD candidate at Murdoch University, highlighted the severity of the issue, stating, "these microplastics are turning food-producing land into a plastic sink" [10]. High concentrations of plastic residues - more than 240 kg per hectare - have been shown to harm soil productivity and plant growth [2]. By 2040, microplastics are expected to account for 79% of all plastic pollution in high-income economies [12]. This alarming trend signals significant environmental challenges ahead.
Waste Mismanagement
The issue of plastic waste mismanagement further exacerbates the environmental burden in North America. Littering alone accounts for 53% of debris emissions in the Global North, contributing to the region's plastic pollution [11]. North America emits approximately 0.03 million tonnes of plastic debris annually, with an average of 0.09 kg per person per year [11]. Rigid plastics dominate the waste streams, making up about 67% of the total, compared to 33% for flexible plastics [11]. In the United States, food and its packaging contribute to over 45% of solid waste [3]. Recycling rates for agricultural plastics remain low, with most being buried, landfilled, or incinerated [1].
Environmental and Soil Impacts
As seen globally, plastic residues in North American soils disrupt critical processes. They impede water infiltration, reduce water retention, and degrade soil fertility [2]. Microplastics and nanoplastics, along with chemical additives like phthalates and bisphenols, negatively affect soil microbes and larger soil organisms [2]. Sewage sludge, or biosolids, used as fertiliser is another major pathway through which micro- and nanoplastics, along with harmful chemicals, enter agricultural soils [3]. Professor Elaine Baker from the University of Sydney, a co-author of a Foresight Brief, emphasised:
"We are starting to understand that the build-up of plastic can have wide-ranging impacts on soil health, biodiversity and productivity, all of which are vital for food security" [5].
Regulatory measures in the region remain insufficient to tackle the problem. For instance, the U.S. FDA has not updated its guidelines on BPA since 2013, while the European Union has already begun restricting certain polymers in fertilisers [5][10].
4. Latin America and Africa
Latin America and Africa, like many other regions, face a tough balancing act when it comes to plastics. On one hand, plastics are vital for agricultural productivity; on the other, they contribute to significant environmental challenges.
Plastic Usage
In these regions, plastics play an important role in agriculture. Farmers use them for seedling trays, irrigation systems, and mulch films, which are critical for many farming operations. The banana industry, in particular, is a significant user, employing plastic sheathes or sleeves to protect fruit during growth and transport [1]. These applications help farmers maintain economic stability by reducing pest damage and water stress [3]. However, the heavy reliance on plastics comes at a cost, as effective disposal systems are often lacking.
Waste Mismanagement
The absence of proper waste management systems amplifies the environmental problems caused by agricultural plastics. In many low-resource areas, plastic waste is either buried, dumped in landfills, or burned in the fields due to the lack of formal collection and recycling infrastructure [1]. Open burning is especially harmful, releasing toxic dioxins and particulate matter that pose risks to both human health and ecosystems. As highlighted in a study published in Nature:
"In resource-constrained settings waste management is often limited to open burning which forms highly toxic, persistent dioxin compounds and particulate matter that imperil livelihoods, ecosystems and public health" [3].
In Kenya, for example, the growing use of plastic mulch and seedling tubes in horticulture has been linked to worsening land degradation [13].
Environmental and Soil Impacts
The environmental consequences of plastic misuse extend beyond just waste. Micro- and nanoplastics are accumulating in agricultural soils, disrupting soil structure and biodiversity. This also reduces the soil's ability to retain carbon. Additionally, harmful chemicals leach from plastics into the soil, potentially entering the food chain through crops [3]. These issues further strain local ecosystems and public health.
Emerging Solutions
Efforts are being made to tackle these challenges. In 2024, the Food and Agriculture Organization (FAO) and the Global Environment Facility (GEF) introduced the "Financing Agrochemical Reduction and Management" (FARM) programme. This five-year initiative in Kenya and Uruguay aims to create regulatory frameworks and promote sustainable alternatives to harmful agricultural plastics [1]. Another GEF-supported project in the banana industry is repurposing banana waste into textiles, reducing the need for virgin plastics and eliminating the open burning of plastic sheathes [1]. In October 2025, UNCTAD explored alternatives for Ghana and Nigeria's cocoa industries, suggesting biodegradable jute liners and seaweed-based bioplastics as substitutes for traditional plastic packaging [13].
These programmes highlight the growing momentum toward addressing plastic-related issues in agriculture across Latin America and Africa.
Comparing Regional Approaches
The way Europe and Asia tackle agricultural plastic pollution reveals their differing priorities and strategies. Europe leans heavily on a circular economy model, implementing mandatory Extended Producer Responsibility (EPR) schemes to manage waste effectively [7][2]. In January 2026, the European Commission introduced pilot actions aimed at speeding up recycling efforts and bolstering markets for recycled plastics [7]. This approach has led to high collection rates and a move towards banning non-biodegradable polymer coatings [2]. These measures reflect Europe's focus on environmental protection but come with economic trade-offs.
In contrast, Asia places a stronger emphasis on increasing agricultural productivity, often at the expense of environmental concerns. For example, China uses extensive film mulching, covering 13% of its farmland. This practice has helped avoid converting an additional 3.9 million hectares into agricultural land, demonstrating its effectiveness in boosting food production. However, this reliance on plastics has significant environmental downsides [2][3]. According to the FAO, "only small fractions of agricultural plastics are collected and recycled, predominately in developed economies. There is evidence that elsewhere most plastics are burned, buried, or landfilled" [7].
Regional Comparison Table
Feature | Europe | Asia |
Primary Goal | Circular economy and environmental protection [7] | Food security and agricultural productivity [3] |
Management Strategy | Mandatory EPR schemes and fiscal incentives [7] | Rapid adoption of "plasticulture" with limited waste management [2][3] |
End-of-Life Treatment | High collection rates; mechanical recycling [7] | Burning, burying, or field abandonment [7][1] |
Regulatory Tools | Bans on non-biodegradable coatings [2] | International research collaborations [1] |
Advantages | Reduced soil contamination; clear policies [7][2] | Higher yields; improved water efficiency; cost-effective for smallholders [2][3] |
Disadvantages | Higher compliance costs for farmers [14] | Severe soil pollution (up to 240 kg/ha); microplastic leakage; long-term soil degradation [7][2] |
The contrast between these regions becomes even more evident when considering the long-term effects. Europe’s stringent regulations reduce soil contamination but drive up costs for farmers and manufacturers. Meanwhile, Asia faces what researchers call a "plastic toxicity debt", where residues from plastic use accumulate in the soil, threatening future productivity [2]. Although both regions apply agricultural plastics at rates of 40–50 kg/ha, their disposal methods - Europe’s focus on recycling versus Asia’s reliance on burning or burial - lead to vastly different environmental outcomes [2].
Global efforts, such as the United Nations-led Global Plastics Treaty negotiations and the FAO's Voluntary Code of Conduct introduced in February 2025, are beginning to influence both regions [3][1]. These initiatives signal a potential shift towards shared solutions, but economic and agricultural differences will likely continue to shape each region’s path. The comparison highlights the complexity of addressing agricultural plastic pollution on a global scale.
Conclusion
Europe has taken a proactive stance on managing agricultural plastics, implementing mandatory Extended Producer Responsibility schemes and banning non-biodegradable coatings. Meanwhile, Asia - particularly China - has focused on productivity, using extensive plastic film mulching to avoid converting an additional 3.9 million hectares into farmland. However, this approach has led to significant soil contamination[2][3]. In 2019 alone, agricultural value chains used 12.5 million tonnes of plastic products, with less than 10% being recycled[1]. This stark contrast highlights the need for solutions that balance productivity with environmental responsibility across different regions.
Moving forward, targeted waste management and material innovation are critical. For plastics that can be collected, such as irrigation pipes and storage crates, the focus should be on reuse and mechanical recycling. However, for items like thin mulch films (under 25 micrometres), transitioning to certified soil-biodegradable polymers is essential to minimise microplastic pollution[2]. In resource-constrained areas, particularly in the Global South, challenges are compounded by the prevalence of open burning, which releases toxic dioxins and fine particulate matter[3].
To address these issues globally, harmonised standards and policies are urgently needed. Initiatives like the FAO's Voluntary Code of Conduct, introduced in February 2025, and the ongoing UN Global Plastics Treaty negotiations are promising steps towards international alignment[1][3]. Meanwhile, programmes such as the Financing Agrochemical Reduction and Management (FARM) in Kenya and Uruguay illustrate how effective regulations can drive investment in sustainable alternatives[1].
"The sustainable management of plastics through a circular economy model in the food sector can offer significant environmental advantages, provided that food safety considerations are thoroughly addressed"[1].
With annual greenhouse gas emissions from agricultural plastics projected to hit 47 million tonnes CO₂eq by 2030 and 98 million tonnes by 2050[1], the path forward requires a combination of strict "essential use" criteria, effective collection systems, and investment in biodegradable alternatives. Only through coordinated global efforts can we manage agricultural plastics effectively and ensure long-term food security.
FAQs
How do agricultural plastics harm soil and ecosystems?
Agricultural plastics gradually degrade, releasing microplastics and chemical additives into the soil. These tiny particles and chemicals can interfere with the soil's natural structure, reduce its fertility, and even contaminate crops. Such contamination not only threatens human health but also impacts surrounding ecosystems.
The build-up of plastics in farmland has another serious consequence: it harms biodiversity. Soil organisms, essential for maintaining healthy soil, struggle to survive in polluted conditions. This growing problem underscores the urgency for eco-friendly alternatives and better regulation of plastic use in agriculture.
What are the key challenges in managing agricultural plastic waste around the world?
Managing plastic waste in agriculture is a complex issue that varies widely across different regions. One of the biggest hurdles is the high cost of collection and recycling, which hits rural areas and small-scale farmers particularly hard. These communities often lack the necessary infrastructure to deal with the problem effectively. Adding to the challenge is the widespread use of plastic products like mulch films, silage wraps, and greenhouse covers, which are scattered across vast areas, making collection even more difficult.
In many places, waste management systems aren't designed to handle agricultural plastics. This often results in soil contamination, loss of biodiversity, and environmental damage. Over time, these plastics can break down into microplastics, releasing harmful chemicals into the soil and jeopardising its long-term health. Addressing these problems calls for localised solutions that take into account the available resources, infrastructure, and specific environmental conditions of each region.
What are some global strategies to tackle agricultural plastic pollution?
Efforts to tackle agricultural plastic pollution worldwide centre around a few vital strategies. One approach is the creation of biodegradable plastics that can naturally decompose, helping to minimise long-term waste. Another is improving recycling systems to ensure agricultural plastics are effectively collected and repurposed, reducing the need for new materials. There's also a push towards sustainable packaging alternatives, offering eco-friendly options for farmers and suppliers.
In addition, many programmes advocate for circular economy principles, which focus on reusing materials and making better use of resources. Governments and organisations are also stepping up efforts to eliminate unnecessary single-use plastics by introducing forward-thinking policies and leveraging new technologies. Together, these strategies aim to lessen the environmental burden of plastic use while paving the way for a greener, more sustainable future.
