Sustainable packaging is becoming popular in today’s environment. This is more so because 51 trillion microplastics and 25 trillion macroplastics fill our oceans. At the same time, 79% of plastic waste fills landfills.
Therefore, to reduce this issue of environmental damage, sustainable packaging solutions come in handy. And one of these solutions is the PET bottles. These PET bottles are environmentally conscious.
They ensure that you can reduce your carbon footprint. Let’s learn more below.
Advantages of PET bottles over other packaging materials
There are many benefits that come with using PET bottles over other packaging materials. They include the following:
They are Lightweight
One of the main reasons why PET bottles are popular today is because they are portable and lightweight. These features make them better than the traditional glass bottles. Traditional glass bottles are heavier and not convenient to carry around.
This is especially if you want to fill them with your daily beverages, such as water. So, the PET bottles make the perfect packaging solution. They are lightweight, which means that they are easier for consumers to carry around.
Also, the lightweight feature ensures less energy consumption and lower transportation costs, especially if you intend to carry many bottles at once.
They are Shatter Proof
Unlike the glass bottles, PET bottles are shatter proof. This means that when they fall down, they will not easily break down. So, for businesses, using a PET bottle for packaging can be incredibly beneficial.
You will not suffer the risk of your bottle’s content spilling out and causing you a loss. At the same time, consumers can enjoy the portability of the bottle without fearing that a breakage will occur.
They are Eco-friendly
PET bottles are the perfect packaging material for any eco-conscious supplier, consumer, and manufacturer. As mentioned earlier, these bottles are lightweight.
What does that indicate? It shows that they’ll use less energy during transportation. Therefore, they ensure less carbon emission. At the same time, they are recyclable. Also, they use less energy and water and generate less emissions than aluminum and glass during production.
They are Transparent
Unlike an aluminum bottle, a PET bottle allows you to see its contents clearly. This means that businesses can showcase their beverages or other content attractively. On the other hand, consumers can inspect the color, quality, and freshness of the bottle’s content.
In short, the transparent bottle can help in purchase decisions.
They are Safe and Durable
PET bottles have non-toxic properties. This makes them ideal for food storage. Also, they are great barriers against gases such as hydrogen, CO2, oxygen, or any other atmospheric gases. So you don’t have to worry about food contamination.
In addition to the safety, the bottles are pretty durable. As mentioned earlier, they are shatter proof. So, they’ll maintain their integrity during transportation.
Innovations in sustainable PET bottle design
There are many current innovations in sustainable PET bottle design. One of the most popular innovations is lightweight design. Today, companies like Coca-Cola are introducing bottles that use less material.
This ensures that they reduce the weight of the bottle, conserve resources, and reduce their carbon footprint. In addition to the ultra-light-weight design, there is also the innovation of bio-based PET.
Bio-based PET bottles are made from plant based materials,like sugarcane. This makes them more environmentally conscious that the traditional petroleum based PET.
Another innovative design is the use of recycled PET bottles. What does this mean? It means that manufacturers don’t engage in virgin production of PET bottles. Instead they use the recycled ones to make new bottles with different shapes and sizes.
Impact of PET bottles on carbon footprint
As indicated earlier, PET bottles are more eco-friendly compared to other packaging materials. They produce less carbon footprint compared to aluminium and glass. This is because manufacturers use materials and energy more efficiently during production.
That energy and material efficiency means low greenhouse gas emission. And it supports the global effort to decrease the impacts on climate change.
In addition to that, PET is a great candidate for closed-loop recycling system. It means that manufacturers can recycle the used bottles many times and they will still maintain their integrity.
That process ensures the reduction of plastic wastes in landfills and waterways. Also, it reduces carbon emissions by about 42%. Therefore, recycling PET promotes environmental preservation.
In addition, it reduces environmental degradation and encourages a more sustainable manufacturing model.
Recycling programs enhancing PET sustainability
As mentioned earlier, PET bottles are one of the most sustainable packaging materials available today. One contributor to this is that they are recyclable. Below are some of the recycling programs that enhance PET’s sustainability;
- PET Recycling Coalition. This program encourages PET recycling and the acceptance of non-bottle PET items, like trays and cups.
- PET Partnership. It works towards improving PET bottle recycling rates, now at 28%.
- Closed-loop systems. They help to reduce virgin PET production. These systems encourage the use of recycled PET (rPET) to make new bottles.
- Nationwide Bottle Deposit System that encourages countries to meet their recycling targets.
How consumers can choose sustainable PET packaging
Eco-conscious consumers can also play an essential role in promoting environmental sustainability. They can do this by choosing sustainable PET packaging. Below are some ways to choose sustainable PET packaging;
- Choose products packaged in rPET. You can check for labels or statements that show the use of recycled materials. When you do that, you will promote the closed-loop system of recycling.
- Support brands that use recycled PET to reduce their packaging waste.
- Go for ultra-light PET packaging materials as they use less material.
- Choose the smallest packaging size that meets your needs. This will help to reduce material wastage.
- Consider reusable PET containers.
- Check for clear recycling symbols on the packaging to ensure that you can recycle them in your area.
