Eco Friendly Trash Bags

Eco-Friendly Trash Bags - What to Look For in Environmentally Friendly Rubbish Bags

Throwing your trash away is an integral part of cleaning up your space. As per most single-use plastics, every time we throw away our trash in the standard black bag, we incur a cost to the environment. Hence we’re going to look at eco-friendly trash bags and the choices you have to bag your trash with less harm to the environment.

Traditional trash bags consist of plastics that end up in landfills. While this may go unnoticed, these bags can take years to decompose, posing harm to our environment.           

Also, plastic trash bags break down into microplastics that can contaminate the ocean and poison its animals. Furthermore, the manufacturing and processing of plastic trash bags contribute to greenhouse gas emissions causing environmental pollution.

To save our environment and reduce these negative effects, eco-friendly trash bags like compostable bags, biodegradable bags, reusable bags, and recycled plastic bags have now become the more sustainable option.

In this article, you will find out all you need to know about eco-friendly trash bags to help you make a more informed decision towards protecting the environment.

We all need some trash bags to get rid of things like kitchen trash, wet food scraps, food waste, pet waste, and other trash around our space.  

However, using single-use plastic trash bags have a major side effect on the environment. 

Manufacturers extract most ‘normal’ plastic bags from fossil fuels which release harmful chemicals into the atmosphere. Manufacturers make regular plastic bags from polyethylene, a common type of plastic derived from petroleum or natural gas. 

These plastic bags can take many years to decompose and contribute to a larger carbon footprint. While these carbon footprints may vary throughout the lifecycle of plastic bags, reports show that plastic could be responsible for over 56 gigatons of the carbon footprint from now till 20505

Each stage of the plastic lifecycle, from fossil fuel extraction to plastic refining and managing plastic waste, releases greenhouse gas emissions leading to global warming and climate change. 

Water pollution is also a significant side effect of plastic production and use. Plastic trash bags break down into microplastics, and these microplastics can contaminate the ocean and poison its animals. It also interferes with the ocean's natural ability to absorb carbon dioxide.

When we investigate these environmental effects, we see the importance of choosing more eco-friendly alternatives. 

What to consider when buying eco-friendly trash bags

While plastic bags are durable, they are not biodegradable and largely contribute to environmental pollution. 

Today, there are several eco-friendly alternatives to plastic trash bags, like compostable trash bags and biodegradable trash bags. 

Here are a few things to consider when you go shopping for an eco-friendly trash bag: 

Sustainable materials 

Manufacturers make eco-friendly trash bags using sustainable materials like plants. Plant-based bags are one of the best options to go for when picking out an eco-friendly trash bag. They release fewer greenhouse gases and won’t contribute to the plastic waste in landfills, making it a more eco-friendly alternative. 

Third-party certifications

Consider eco-friendly trash bags that come with third-party certifications. This ensures you use a trash bag made of sustainable materials sourced and harvested without harming the environment. 

Some of these certifications include ASTM International Standards, TUV AUSTRIA, Biodegradable Products Institute Certification (BPI), OK Compost Home Certified, and so on. 

Leak-proof 

You want to make sure your trash bag saves the planet and gets the job done. Consider trash bags with good sealing properties that keep your trash properly contained and leak-proof. 

Biodegradable and compostable trash bags - what you should know

We often regard biodegradable and compostable trash bags as better eco-friendly alternatives.  Sometimes we use the word ‘biodegradable’ and ‘compostable’ bags interchangeably to mean the same. However, they are not the same. Primarily, not all biodegradable trash bags are compostable. 

In this section, we will carefully examine the difference between these two trash bags.

Biodegradable trash bags

We consider a trash bag biodegradable if it breaks down into smaller materials caused by microorganisms when left in a natural environment. 

Manufacturers typically make biodegradable trash bags using petroleum-based plastics. However, they manufacture it in a way that allows these bags to break down when exposed to living organisms in landfills. 

While this looks marketable on paper, the degradation process can prove vague, and less scrupulous providers may avoid saying how long it takes for biodegradation to happen. Also, microorganisms can break down these plastics into smaller chains of plastic which can still be harmful to the environment.  

Furthermore, the Environmental Protection Agency secures a typical landfill in such a way6 that air, sunlight, and moisture, which are necessary conditions for biodegradation, are blocked out. 

This means that a biodegradable trash bag could be sitting exposed in landfills, unable to decompose completely. 

Compostable trash bags 

Compostable trash bags are a better version of biodegradable bags. Compostable bags come from plant matter like corn starch instead of petroleum-based plastics. When a compostable trash bag is exposed to sufficient moisture and heat, it composts easily alongside other organic materials like food scraps and yard waste. 

However, it is important to note that we must dispose of compostable bags under the right conditions. These bags do not give off toxins or chemicals that can be harmful to the environment. If these bags end up in landfills, they become equally toxic. A compostable bag should be disposed of in an industrial compost facility, or you can create a home compost pile. 

If waste goes through high heat in an industrial facility, it should break down rather quickly. However, a home compost pile decomposes much slower and could take up to a year, depending on the size and conditions. 

We have a more detailed breakdown of the difference between biodegradable and compostable over here for further information.

Pros and cons of compostable trash bags 

Pros

  • Compostable trash bags do not produce toxic by-products making them more environmentally friendly than the typical plastic bag.
  • Manufacturers make them from renewable plant matter like corn starch. 
  • They break down into soil nutrients under the right conditions.  

Cons 

  • Compostable trash bags are more expensive than standard plastic bags.
  • They are sometimes thin and are likely to leak off when overstuffed with trash. 
  • It can dissolve into your trash can if exposed to too much moisture.

What certifications should you look out for?

There are some third-party certifications to look out for when purchasing a compostable garbage bag. These certifications validate that the garbage bag is compostable and can decompose in an eco-friendly way. 

  1. ASTM International Standards: ASTM is an international standard organization that provides third-party certifications for many products, including eco-friendly trash bags. Compostable trash bags have to meet these fundamental requirements of the ASTM D6400 to be legally compostable4:  
    - In a compostable environment, the product must completely decompose to a point where it cannot be distinguished from the finished compost product. 
    - Microorganisms must break down the product at a rate that is similar to other known compostable materials. 
    - The final compost product must be environmentally friendly and must contribute to plant growth. 
    - According to ASTM, industrial composting in a well-managed facility should take 84 days for product fragmentation and 180 days to completely mineralize into the soil2.
  1. Biodegradable Products Institute Certification (BPI): The Biodegradable Products Institute is one of the most prominent certification organizations in North America. It issues certifications for compostable products and indicates that the products meet the ASTM D6400 (for products including a trash bag) and ASTM D6868 (for packaging).
  2. TUV AUSTRIA: This certification organization is similar to BPI but in Europe. They offer several certifications, including the OK compost industrial and OK compost home. The OK compost industrial certification confirms that a product will decompose appropriately in an industrial facility. 

The OK compost home certification confirms that a product will decompose in a home composting system. They consider factors applicable in a garden compost heap, including lower temperatures and other conditions. 

  1. European Bioplastics Standard: The European Bioplastics Standard (EN 13432) requires that compostable plastics break down after 12 weeks and completely biodegrade after six months. This means that 90% of plastics should convert to CO2 while the rest convert to biomass and water3.
  2. Austrian Standard Logo: The AS5810 indicates home compostability. In comparison, the AS4736 indicates that the product is suitable for a commercial composting facility. 

Can biodegradable and compostable trash bags be recycled? 

Unfortunately, manufacturers cannot process both biodegradable and compostable bags in recycling facilities. When these garbage bags mix with other petroleum-based plastics, they could contaminate recyclable materials and disrupt the entire recycling process. 

Biodegradable bags should be discarded as trash, while compostable bags should be used as compost material.  

Biodegradable trash bags vs. compostable trash bags - which is better? 

While a zero-waste lifestyle presents the best option, avoiding waste altogether, when using trash bags, compostable is a better choice. They are legally approved and do not produce plastics or toxic by-products. They are also legitimately disposed of in a compost facility.  Alternatively, you can compost it in a backyard compost bin. 

Researchers conducted a study to examine regular plastic bags, biodegradable bags, and compostable bags in different environments. Studies revealed that plastic and biodegradable bags could still hold weight after three years in the soil1. On the other hand, compostable bags couldn’t hold out the weight. In a marine environment, compostable bags decomposed in three months.
