What You'll Learn
Plastic-wrapped hay lasts longer
Plastic film, made from LDPE, is commonly used to wrap bales of hay. It is a flexible, lightweight, strong, and durable material that creates an effective barrier against moisture. It also protects the hay from the elements, ensuring that it stays dry and safe for consumption for months or even years. This is especially important in cold, wet, and windy climates like Iceland's, where hay may need to be stored for extended periods before being used as animal feed.
The use of plastic wrapping has some benefits for farmers. It is cost-effective and widely available, making it a popular and convenient choice. Additionally, plastic film is easy to recycle, which is essential as large amounts of plastic waste can be generated from wrapping hay bales. Recycling programs for farm plastic waste help minimise the environmental impact of plastic use in agriculture.
The colour of the plastic wrapping is also significant. In Iceland, white, black, and light green plastic wrappings are commonly used. White reflects sunlight efficiently, reducing the impact of heat fluctuations on the hay. Darker colours, on the other hand, cause the different layers of wrapping to melt together, creating a solid cover that decreases oxygen penetration into the hay bales.
While plastic-wrapped hay does have its advantages in terms of longevity and hay quality, there are valid environmental concerns. Plastic is not biodegradable, and improper disposal methods, such as burning or burying, can harm the environment. As a result, recycling is the preferred option for responsible waste management.

White plastic reflects sunlight
Hay is a crucial food source for Icelandic livestock, particularly horses and sheep, and is essential for their health and well-being. Icelandic farmers wrap their hay bales in plastic to preserve their quality and ensure they remain in the best possible condition. Plastic film is a flexible, lightweight material that is easy to wrap around the bales, providing an effective barrier against moisture.
The plastic wrapping used in Iceland is usually available in white, black, and light green. White plastic wrapping reflects sunlight more efficiently than other colours, so heat fluctuations have less of an impact on the hay. This is particularly important as high moisture levels can cause the hay to rot and become mouldy, which can be harmful to animals who consume it. The plastic wrapping keeps moisture levels low, ensuring that the hay remains dry and safe for consumption.
Although plastic wrapping helps preserve the quality of the hay, it is not biodegradable and can remain in the environment for hundreds of years. This is a concern for farmers who must dispose of large amounts of plastic wrap after the hay has been used. However, plastic film is easy to recycle, and some companies specialise in recycling farm plastic waste, minimising the environmental impact.

Plastic is not biodegradable
In Iceland, it is a common sight to see rolls of hay bales wrapped in plastic. While this practice may be convenient, it raises concerns about the environmental impact of plastic waste. Plastic is a significant contributor to pollution, and it is essential to understand why it is not biodegradable and the consequences of its persistence in the environment.
Firstly, it is important to recognize that plastic is derived from oil and gas, which are fossil fuels formed from the remains of ancient living organisms. Through a process of heating and catalysis, the propylene in petroleum forms polymers, which are long chains of molecules. These polymers are the building blocks of plastic, and they are not naturally abundant.
The key issue with plastic's biodegradability lies in the fact that the enzymes in microorganisms, which are responsible for breaking down biodegradable materials, do not recognize the bonds that hold these polymers together. As a result, plastic does not biodegrade completely, even over thousands of years. Instead, it breaks down into smaller and smaller pieces, known as microplastics, and eventually, nanoplastics. These tiny particles can infiltrate our environment, releasing harmful chemicals and posing risks to wildlife and human health.
The persistence of plastic waste has severe environmental implications. Landfills, the common destination for plastic trash, eventually leak and contaminate the soil, air, and waterways with toxic chemicals. Incineration, another method of disposal, releases pollutants into the air and leaves behind ash that ends up in landfills. Single-use plastic packaging contributes significantly to this waste, with an average person in the US using hundreds of disposable bags and plastic bottles annually.
While biodegradable plastics have been developed, they are not a perfect solution. These plastics still require specific conditions, such as defined temperatures and microorganisms, to biodegrade effectively. In natural environments, they may only slowly biodegrade or fragment into microplastics. Therefore, the most effective approach to mitigating plastic pollution is to reduce plastic use, promote reuse, and recycle when necessary.
In conclusion, plastic's non-biodegradability stems from the unique chemical structure of polymers and the inability of microorganisms to break them down. This leads to the persistence of plastic waste in the environment, causing severe ecological and health issues. To address this problem, it is crucial to transition to sustainable alternatives, such as refillable containers and reusable packaging, and to advocate for policies that reduce single-use plastic consumption.
