Plastic waste has become one of the most pressing environmental issues of our time, and Australia is no exception. Each year, the country consumes a staggering one million tonnes of plastic, with 84% of plastic being sent to landfill and only 13% recycled. The vast majority of this plastic is single-use, contributing significantly to the growing waste crisis. The consequences are dire: approximately 130,000 tonnes of plastic leak into the marine environment every year, harming wildlife and disrupting ecosystems.

As awareness of this issue grows, Australians are looking for ways to reduce their plastic footprint. One area where significant progress can be made is in the use of eco-friendly bin liners. Traditional plastic bags, often made from virgin materials, contribute to the plastic waste problem. In contrast, bin liners made from post-consumer recycled materials offer a more sustainable solution, helping to close the loop on plastic recycling and reduce the amount of plastic waste that ends up in landfills and oceans.

The different types of bin liners

Choosing the right bin liner might seem like a small decision, but it can make a big difference when it comes to the environment. There are several types of bin liners available, and each comes with its own set of benefits and environmental impacts. In this section, we’ll take a closer look at the most common types of bin liners and what you need to know before making a choice.

1. Traditional plastic bin liners (virgin plastic)

Traditional plastic bin liners are made from virgin plastic, which means they’re produced from brand-new, non-recycled materials. These bags are strong and durable, which is why they’re commonly used in homes and businesses. However, the environmental downside is that they contribute to the growing issue of plastic waste. Since they’re made from new plastic, they require more resources to produce and can take hundreds of years to break down in the landfill.

Virgin plastic bin liners are not recyclable in most cases, and they often end up in landfills or polluting the environment.

2. Recycled plastic bin liners

Recycled plastic bin liners are a much better option because they are made from post-consumer recycled (PCR) plastic. This means the plastic is repurposed from items that have already been used, like old bottles, containers, and packaging. Recycled plastic bin liners help close the loop on plastic waste by using materials that would otherwise end up in landfills. While the recycling process does require energy, it’s still a more sustainable option compared to using virgin plastic.

Brands like Thinkpac take it a step further by offering 100% post-consumer recycled materials, like their ReCree8® resin, making them a great eco-friendly choice for reducing plastic waste.

3. Biodegradable bin liners

Biodegradable bin liners are marketed as an eco-friendly alternative because they break down faster than traditional plastic when exposed to certain conditions, such as in compost or landfill environments. These liners are often made from plant-based plastics, which are derived from renewable resources like corn starch or sugarcane.

While biodegradable bags do break down faster than traditional plastic, they still have environmental challenges. In landfills, where there’s little oxygen, biodegradable plastics can take years to decompose. If they end up in the ocean, they might break down into microplastics rather than fully decomposing. Additionally, the production of plant-based plastics can sometimes involve significant amounts of water, land, and energy, so the sustainability benefits can vary.

Biodegradable doesn’t always mean better for the planet—it’s important to dispose of these bags properly to ensure they break down as expected.

4. Compostable bin liners

Compostable bin liners are a type of biodegradable bag, but with a key difference—they’re designed to break down into non-toxic organic matter in composting environments. Typically made from materials like cornstarch or PLA (polylactic acid), these bags are perfect for composting food scraps and organic waste.

When disposed of in industrial composting facilities, compostable bags decompose into natural materials that can be used to enrich the soil. However, they won’t break down properly in regular landfill settings, so it’s important to ensure they go to the right place. Compostable bin liners are a great option for those who have access to composting services and want to reduce waste.

Always check if your local area has a composting facility before using compostable bags, as they won’t decompose in regular trash bins.

HDPE vs LDPE

When shopping for bin liners, you may have come across the terms HDPE (High-Density Polyethylene) and LDPE (Low-Density Polyethylene). These are two of the most common types of plastics used in bin liners, and understanding the differences between them can help you make a more informed choice about which is best for your needs and the environment.

What is HDPE (High-Density Polyethylene)?

HDPE is a type of plastic known for its strength, durability, and high resistance to impact. It is made using a more rigid molecular structure, which gives it greater stiffness and strength compared to other types of plastic. HDPE bin liners are typically used for heavier-duty tasks, such as storing industrial waste or sharp objects, as they are more resistant to tearing and puncturing.

Key features:

Stronger and more rigid than LDPE, making it more durable.
Better for heavy-duty use and rougher environments.
Typically thinner and stiffer, which means they’re more efficient at holding waste without stretching or ripping.

While HDPE is more easily recycled than other types of plastic, like LDPE, it is still made from virgin plastic in many cases, which can contribute to plastic waste if not recycled properly. HDPE is a better option than LDPE when it comes to recycling, as it has a higher rate of successful recycling.

What is LDPE (Low-Density Polyethylene)?

LDPE is a type of plastic that has a more flexible and softer structure, making it ideal for products like plastic bags, stretch wraps, and lighter-duty bin liners. Unlike HDPE, LDPE is less resistant to wear and tear, so it’s typically used for lighter waste that doesn’t need the same durability. LDPE bin liners are more flexible, allowing them to stretch and fit snugly into bins of all sizes.

Key features:

Flexible and soft, allowing the bags to stretch easily.
Ideal for lighter waste, such as food scraps, paper, and non-sharp items.
More prone to punctures and tears compared to HDPE bin liners, so they may not be suitable for sharp or heavy waste.

LDPE is more difficult to recycle than HDPE and, in most cases, is not accepted by curbside recycling programs. While LDPE bags can be recycled in specialised facilities, the lack of widespread recycling options means they are more likely to end up in landfills.

Eco-friendly vs biodegradable: What do these terms really mean?

You might come across terms like eco-friendly and biodegradable being used interchangeably. However, it’s important to understand the difference between these two terms as they refer to very different properties, especially when it comes to plastic bags and bin liners.

What does “eco-friendly” really mean?

The term eco-friendly is often used to describe products that are less harmful to the environment compared to traditional alternatives. When it comes to eco-friendly bin liners, it typically refers to products made from recycled materials (like post-consumer recycled plastic), which helps reduce the demand for new plastic production and lowers waste. An eco-friendly bin liner might also be made from sustainable materials that have a lower environmental impact, such as those made from plant-based sources or certified recycled plastics.

Key features of eco-friendly bin liners:

Made from recycled materials, such as ReCree8® resin used in Thinkpac’s eco-friendly bin liners.
Designed to reduce the use of virgin plastic, which helps conserve resources.
Often come with a lower carbon footprint compared to products made from new plastic.
May be reusable or made with less harmful chemicals during production.

Eco-friendly bin liners are generally considered a sustainable choice because they help reduce waste, conserve resources, and contribute to a circular economy by reusing plastic materials that would otherwise end up in landfills.

What does “biodegradable” really mean?

On the other hand, biodegradable refers to products that are designed to break down into natural elements when exposed to environmental conditions like heat, moisture, and oxygen. The idea is that these materials will decompose more quickly than traditional plastics, which can take hundreds of years to break down in landfills. Biodegradable bin liners are often made from plant-based plastics, such as cornstarch or PLA (polylactic acid), which are meant to break down more easily when exposed to the right conditions.

However, it’s important to understand that biodegradable products don’t necessarily break down as quickly or completely as you might think. In landfills, where there’s limited oxygen, biodegradable materials can still take years to decompose. Moreover, biodegradable plastics can still release harmful microplastics if not properly disposed of.

Key features of biodegradable bin liners:

Made from plant-based plastics or materials designed to break down more quickly than traditional plastics.
Designed to decompose into natural elements when exposed to environmental conditions.
Often marketed as an environmentally friendly option due to their faster breakdown time.
