Avocados have become a staple in the diets of many people around the world, with the global avocado market valued at over £7.15 billion in 2021. However, the environmental impact of avocados has come under scrutiny in recent years. While avocados themselves are biodegradable, the plastic and cardboard packaging used to sell them often is not. In addition, the water-intensive nature of avocado cultivation and the heavy use of fertilisers and fossil fuels in avocado plantations contribute to environmental concerns. This paragraph will explore the question: are avocados more wasteful than plastic?
| Characteristics | Values |
|---|---|
| Avocados' environmental impact | Avocados have a high carbon footprint, with a carbon footprint of around 2.5kg of CO2 equivalent per kg, which is more than twice as high as bananas and over five times higher than apples. Avocados are also a water-intensive crop, requiring significantly more water per kilogram than many other fruits and vegetables. |
| Plastic's environmental impact | Plastic takes nearly 700 years to biodegrade, and less than 20% of plastics are recycled. |
| Avocados as a solution to plastic waste | Avocado peels can be used to make biodegradable films, which could potentially replace plastic as a packaging material. These films are robust, transparent, and biodegrade within 30 days at 22% soil moisture. Biofase has also developed a process to transform avocado pits into biodegradable plastics, such as cutlery and straws. |
| Avocados and plastic waste | Avocados are frequently packaged in plastic, contributing to plastic pollution. Pre-peeled, pre-halved avocados sealed in plastic and cardboard have been criticised as an example of wasteful packaging. |

Avocados' carbon footprint
Avocados have become an increasingly popular food item, but their environmental impact is a growing concern. Avocados have a high carbon footprint, with around 0.85 kg of CO2e per pound of avocados. This is primarily due to transportation emissions, as most avocados consumed in countries like the United States and the UK are imported from places like Mexico, Peru, Kenya, and Chile. The large distances that avocados need to be transported contribute significantly to their carbon footprint.
In addition to transportation, avocado production itself has an impact on the environment. Avocado farming is a water-intensive process, requiring 140-320 litres of water per avocado, depending on the region. This high water demand can put pressure on local water supplies, especially in areas with water scarcity. Furthermore, large-scale avocado farming has been linked to soil degradation and deforestation, particularly in Mexico, the world's largest producer of avocados. The expansion of avocado plantations has led to the clearing of forests, contributing to climate change and soil erosion.
However, it's important to note that the environmental impact of avocados is lower than that of most animal products. Well-managed avocado plantations can be sustainable, with some relying on natural, seasonal irrigation or sustainable, high-tech irrigation methods such as drip irrigation. Consumers can also make more sustainable choices by opting for locally grown avocados when possible and consuming them in moderation.
While avocados have a carbon footprint, they are also being explored as a potential solution to plastic waste. Avocado peels and pits can be used to create biodegradable materials, which could replace traditional plastic packaging. These biodegradable films are robust, transparent, and biodegrade within 30 days at 22% soil moisture, making them an environmentally friendly alternative.

Avocados' water consumption
Avocados have become a staple in diets around the world, particularly in the US and Europe. However, the rapid growth of the avocado market has put a strain on local ecologies, especially water resources. Avocado production is highly water-intensive, and countries that grow avocados are facing drought and water shortages.
Avocados are grown in many relatively arid regions, such as Southern California, Northern Chile, and Mexico. In these dry areas, avocado production requires even more water than usual. For example, in the Petorca province of Chile, where water is already scarce, every cultivated hectare of avocados requires 100,000 liters of water per day, equivalent to the daily water consumption of a thousand people. The region has experienced droughts and water shortages, with residents receiving only 50 liters of water per day, a fraction of what avocado trees need.
The water-intensive nature of avocado production is due in part to the large amount of water required to grow a single avocado. According to the Water Footprint Network, it takes 2,000 liters of water to produce one kilo of avocados, or roughly 70 liters per fruit. This is four times the amount needed to produce a kilo of oranges and ten times that of a kilo of tomatoes.
However, it is important to note that well-managed avocado plantations can be sustainable. For example, in Michoacán, Mexico, approximately 61% of avocado orchards rely on natural, seasonal irrigation, and 36% use sustainable, high-tech irrigation methods such as drip irrigation. Additionally, consumers can help reduce the water consumption footprint of avocados by opting for locally grown avocados when possible and consuming them in moderation.

Avocados' packaging waste
Avocados have become an increasingly popular fruit in the United States and worldwide. However, their growing demand has led to concerns about their environmental impact, particularly regarding packaging waste.
One example of wasteful avocado packaging is the practice of selling pre-peeled, halved avocados wrapped in plastic and cardboard. This method of packaging avocados has been criticised as wasteful and unnecessary, especially given that avocados are typically sold with natural packaging in the form of their peels.
However, there are ongoing efforts to address the environmental impact of avocado packaging. Researchers have explored the potential of using avocado waste, including peels, pits, and tree pruning residue, to create biodegradable materials that can replace traditional plastic packaging. These avocado-based materials are strong, transparent, and biodegradable, offering a promising solution to the problem of plastic waste.
For instance, a study by Srinivas Janaswamy and Shafaet Ahmed from South Dakota State University found that avocado peels could be used to create biodegradable films suitable for packaging. Their research, funded by the USDA's National Institute of Food and Agriculture, aimed to develop a strong, sustainable, and flexible packaging material that biodegrades quickly and is made from agricultural residues. Similarly, researchers from the University of Cordoba and the University of Girona in Spain have developed a biocomposite material by incorporating avocado pruning fibres, which exhibits increased tensile strength and durability compared to traditional packaging materials.
These innovations in avocado packaging waste show potential in reducing the environmental impact of avocado consumption and contributing to more sustainable practices in the industry.

Avocados' contribution to deforestation
Avocados have become increasingly popular worldwide, with the global avocado market valued at over £7.15 billion in 2021. This popularity has led to a surge in demand, which has had a significant environmental impact. One of the most notable consequences is the contribution of avocado production to deforestation, particularly in Mexico.
Mexico is one of the largest producers and exporters of avocados, with the state of Michoacán being the country's top avocado-producing region. However, the avocado industry in Mexico has been associated with illegal deforestation and environmental degradation. Each year, thousands of acres of forest are cleared to make way for avocado orchards. This practice has led to a loss of carbon sinks, disrupted natural filtration processes, and increased water scarcity in the region.
The high profitability of avocado farming compared to other crops has incentivized farmers to engage in deforestation, even in protected areas. In some cases, this has been driven by criminal organizations and cartels, who have exploited the lucrative nature of the avocado business. Local cartels have been implicated in bribery, extortion, and violence to maintain control over the industry.
To address the issue of deforestation, the Mexican government and environmental organizations have implemented initiatives to promote sustainable practices and certify eco-friendly avocado production. The Pro-Forest Avocado certification program, for example, uses satellites to monitor orchards for signs of clear-cutting and ensure that only sustainably grown avocados are exported.
While avocados have been associated with deforestation, it is important to note that well-managed avocado plantations can be sustainable. Some regions in Mexico, such as Michoacán, utilize natural and sustainable irrigation practices. Additionally, companies are exploring ways to reduce waste by upcycling discarded avocados and using avocado peels and pits to create biodegradable materials and packaging.

Avocados' potential as a plastic alternative
Avocados have become an increasingly popular fruit in the United States and worldwide. However, their environmental impact has been a growing concern, with food waste and plastic pollution being significant contributors. In this context, researchers are exploring the potential of avocados, specifically avocado peels, as a sustainable alternative to plastic packaging.
Avocado peels have been found to contain fibres that can be used to create biodegradable films, which could potentially replace plastic packaging. These films are not only robust and transparent but also biodegrade within 30 days at 22% soil moisture, making them environmentally friendly. This addresses the issue of plastic's inability to biodegrade, which has led to a global waste problem.
The research conducted by Srinivas Janaswamy, an associate professor at South Dakota State University, and Shafaet Ahmed, a graduate research assistant, highlights the potential of avocado peels in developing biodegradable packaging materials. Their work tackles the dual problems of plastic waste and food waste, as avocado peels are often discarded.
Additionally, avocado pruning residue, which is abundant due to the popularity of avocados, has been explored as a sustainable reinforcement for plastic packaging. By mixing the leaves and branches of the avocado tree with soda and refining the pulp, researchers were able to isolate fibres with increased cellulose content. These fibres provide structural stability and can be used to partially replace bio-based polyethylene, reducing the amount of plastic used.
Furthermore, avocado pits have also gained attention as a source of biodegradable plastics. Morelia-based company Biofase, founded by Scott Munguía, manufactures biodegradable straws and cutlery from avocado seeds using a patented process. These products biodegrade within 240 days when exposed to the elements or buried in the ground, significantly faster than their fossil fuel-based counterparts.
