Compostable Bags: Everything You Need To Know

Introduction To Compostable Bags

If you're looking for an environmentally friendly way to dispose of your trash, compostable bags might be the perfect option for you. These bags are made from biodegradable materials that can be composted in a compost bin or pile. In this blog post, we will discuss everything you need to know. We're also excited to spotlight Plastno, a trailblazer in the production of 100% compostable plastic bags. And here's the exciting part: Plastno is offering our readers an exclusive discount on their products (see below)!

Ingredients: Natural Materials Like Cornstarch, Vegetable Oil

Compostable bags are an eco-friendly alternative to traditional plastic bags. Unlike plastic, these are made from natural materials like coffee grounds, cornstarch, or vegetable oil. As a result, they break down into compost, which can be used to fertilize the soil. These are also typically stronger than plastic ones, so they can better resist tearing and breaking.

Compostable Is Not Biodegradable

However, these products should not be confused with biodegradable ones. Biodegradable bags are made from synthetic materials that eventually break down into small pieces of plastic. While biodegradable bags may be less harmful to the environment than traditional plastic bags, they still take centuries to decompose completely. In contrast, compostable bags decompose quickly and completely, making them a much more sustainable option.

Why Are Compostable Bags Important

Compostable bags are important because they help to reduce the amount of waste that ends up in landfills. Unlike traditional plastics, these can be broken down by bacteria and other microorganisms. This process, known as composting, results in the production of beneficial compost that can be used to improve soil quality.

In addition to reducing the amount of waste in landfills, these also help to reduce greenhouse gas emissions. The process of decomposing organic matter in the anaerobic conditions of a landfill releases methane, a powerful greenhouse gas. However, when compost is properly managed, it can serve as a carbon sink, helping offset some of the methane emissions from other sources. As a result, compostable bags play an important role in mitigating climate change.

Certification ' How To Evaluate Claims Of Compostability

BPI (Biodegradable Products Institute) Certification and TUV Certification are helpful standards that indicate a product's environmental impact, with a particular focus on its compostability and biodegradability.

  1. BPI Certification: The Biodegradable Products Institute (BPI) is a professional association that promotes the use, development, and acceptance of compostable products. A product that has been BPI Certified has undergone rigorous testing to ensure it will safely compost in a municipal or commercial facility. This certification is based on the standards set by the American Society for Testing and Materials (ASTM), specifically ASTM D and D. Products bearing the BPI logo have been verified to decompose quickly, completely and safely, without leaving any harmful residue.
  2. TUV Certification (2 different certifications): TUV, or Technischer Überwachungsverein, is a German organization that validates the safety and quality of products. TUV provides two key certifications: TUV Austria's OK Compost for industrial composting and OK Compost HOME for home composting. These are based on the European standard EN . Products with these certifications have been tested to ensure they will biodegrade in an industrial composting plant or a home compost heap respectively, within a specified time frame.

Both BPI and TUV certifications are aimed at reassuring consumers that the products they purchase are indeed capable of biodegrading as claimed by the manufacturers, contributing to better waste management and environmental conservation.

Compostable Containers In General

Compostable containers are an essential step in reducing the environmental impact of waste. This not only reduces the amount of waste sent to landfills but also provides a valuable source of nutrients for plants.

While compostable containers are more expensive than traditional plastic bags, they offer a number of advantages that make them worth the investment. In addition to being better for the environment, compostable containers are also stronger and more durable than plastic containers. They can also be used multiple times, which further reduces their environmental impact. For these reasons, compostable containers are an ideal choice for anyone looking to reduce their waste footprint.

Companies Selling Compostable Bags

An increasing number of companies are now selling compostable bags and prices vary widely. Some companies sell certified compostable bags, which have been tested to meet specific standards for compostability. However, not all of these are certified. In general, certified compostable bags will cost more than non-certified ones.

What To Watch Out For When Buying

Compostable bags are a great way to reduce your environmental impact, but there are a few things you need to watch out for when purchasing them:

  1. Make sure the bags are made from plant-based materials like paper or cornstarch.
  2. Check that the bags are certified by a third-party organization.
  3. Be sure to compost the bags within six months of use; otherwise, they will break down just like regular plastic bags.

It's always a good idea to check with your local waste management facility to ensure that your bags will be properly processed. Additionally, company offerings and certifications can change over time, so I would recommend checking the most recent information about these companies and their products.

By following these simple tips, you can be confident that you're using it in the most sustainable way possible.

Going Beyond Bags

Composting is a great way to reduce your carbon footprint, and compostable products can help make the process easier. With the advancement of science, compostable plastic can be used to make a variety of products, including compostable sandwich bags, compostable straws, compostable plates, compostable bags food waste, etc.

These products can be used for a variety of purposes and are available in a variety of sizes and colors and can be custom-printed with logos or other designs. These are an environmentally-friendly alternative to traditional plastic products and can help to reduce the amount of plastic waste.

Compostable Sacks

Compostable sacks are an important composting tool. They are used to line compost bins and keep food scraps and other organic matter from coming into contact with the bin. This helps to prevent pests and odors.

Compostable Bowls

Unlike paper or plastic bowls, compostable bowls can be broken down by bacteria and fungi into nutrient-rich compost that can be used to fertilize the soil. Compostable bowls are also available in different sizes and shapes to fit your needs. Compostable bowls can also be used to store food in the fridge or freezer. These are made from PLA, a biodegradable plastic derived from cornstarch.

Compostable Trash Bags

Compostable trash bags are an important step in reducing the amount of waste sent to landfills each year. Since it is made from plant-based materials, it decomposes quickly in a compost heap. This means that they won't take up valuable space in a landfill and will instead break down into nutrient-rich compost that can be used to improve your garden soil. Compostable trash bags are also more durable than traditional plastic trash bags, so you won't have to worry about them tearing or spilling during use. And, best of all, they cost about the same as regular trash bags.

Compostable Plastic Bags

Unlike conventional plastic bags, which can take hundreds of years to break down, compostable plastic bags will break down in just a few months when exposed to the right conditions. These bags are also much stronger than conventional plastic bags, so they're less likely to tear and leak. And because they're made from renewable resources, these are a more sustainable choice than conventional plastic bags. A lot of stores have been offering these as an alternative to plastics which are worth more than you realize.

Compostable Poop Bags For Your Dog

Compostable poop bags are an earth-friendly way to dispose of your dog's waste. And unlike paper bags, these will not turn to mush when they get wet. Most brands are sturdy and leak-proof, making them ideal for scooping up messes on walks and in the backyard. Plus, many brands offer larger sizes, so you can use them for small trash cans or larger dog waste bins. Composting your dog's waste is a simple and earth-friendly way to dispose of it.

Composting dog poop is generally not recommended if you intend to use it for growing vegetables as it can introduce pathogens into the compost pile. However, if you are absolutely sure that you won't use your compost soil for growing things, and you are taking all necessary safety and sanitation precautions, then composting dog poop may be an option. Another possibility is to make a separate compost pile for the dog waste and to ensure that the compost pile is properly maintained.

Conclusion

Compostable Produce Bags: All You Need to Know

With the global climate crisis threatening the world in which we live, many people are looking for ways to do their part to help the environment. While big shifts are necessary if we hope to avoid disaster, small changes can add up as well. There are so many tiny steps each of us can take in our daily lives, and every little thing helps. One easy adjustment to make involves the bags we use and the impact they have on our environment.

Everyone knows that plastic takes ages to degrade and has a severely negative impact on our planet in all forms. Single-use plastic grocery and produce bags are an easy place to make a change. Many grocery stores are swapping out their standard plastic grocery and produce bags for biodegradable or compostable options.

The Difference Between Compostable and Biodegradable

Compostable produce bags are made from 100% plant-based materials. These break down at the same rate as other food waste and can be disposed of in a standard composter. They are a great alternative to plastic bags and an easy change to make. You can start by using these bags for your food waste and slowly extend from there. However, there are still better options available, which we will get to shortly.

Biodegradable bags are not nearly as great as their name suggests. Technically, compostable produce bags are a type of biodegradable bag. However, the other bags that fall in this category are not nearly as eco-friendly. Standard biodegradable bags are still made from plastic. The difference is that it contains additional materials to break down much faster than other plastic bags. 

The company is the world’s best custom compostable bags supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

These bags may not continue to occupy space in a landfill for as long as normal plastic bags, but that is really their only good quality. Producing biodegradable bags is still incredibly harmful.

Not All Compostable Produce Bags Will Break Down in Your Home Compost

Some bags are labeled as compostable but will only break down correctly in high enough temperatures. Your home compost system may not do the trick. These bags may need to be processed in special facilities where the compost is guaranteed to reach the desired levels.

Some bags are specifically marked as 'home compostable.' These should meet the necessary conditions to be composted at home. However, if your bag does not have that labeling, it can be challenging to know if the bag will break down in your home system as you desire.

Compostable Produce Bags Are Still Single-Use

While compostable produce bags are a far better option since they are made from plant-based materials, they are still single-use bags. One of the biggest problems with our consumer-based economy is that we treat nearly everything as disposable. With the products we purchase, there is always a new and better version right around the corner. 

Most people make very few of their purchases with the future in mind. It is all about the latest technology, and society pressures people to have the most up-to-date version. Because of this, we quickly use up and dispose of products, and we package all these items in similarly disposable containers. This view pervades all areas of our modern lives.

When people go to the grocery store, they have been conditioned to put their fruits and vegetables in the plastic produce bags provided by the shop. Then they put those plastic bags into other plastic bags at check-out. Even though many stores are replacing their plastic bags with compostable ones, the larger issue is not really being addressed. 

Before plastic came into common use, paper bags were all the rage in grocery stores. Before paper bags, goods were typically moved around in various reusable bags. The paper bag was invented in the first half of the 19th century and quickly gained popularity due to its ease to produce and convenience to use.

That is over 200 years of conditioning we have to overcome to return to regular usage of reusable shopping bags. While we are all aware that it is the best thing to do, bad habits can be hard to break. We must refocus on sustainability over convenience.

Making Compostable Produce Bags Takes Energy

While making a compostable produce bag may use relatively little energy compared to the production of many other bags, the cost is still there. Creating a single reusable canvas tote bag has a greater environmental impact in the production phase than creating a single compostable bag. 

However, one reusable canvas tote bag can replace hundreds and even thousands of compostable produce bags otherwise used by a consumer. The energy used to create that one canvas bag pales compared to the amount necessary to replace it with compostable bags.

Even though compostable produce bags come from renewable plant-based materials, they still require far more resources in the long run to make enough to replace one reusable canvas grocery bag. 

The three R's in conservation are Reduce, Reuse, and Recycle. While they all help the environment, recycling is by far the least efficient of the three. Reducing and reusing products should be the greater focus of our energies, but compostable containers are centered around recycling. They are a good step in the right direction, pushing to eliminate plastic bag usage. However, they are far from an ideal solution.

The Cost of Reusable Bags

It is hard to find a grocery store that does not sell reusable grocery bags, and many grocers also stock reusable produce bags. While there is a cost to purchasing these bags, they can be used for years, and the larger grocery bags can serve many different functions. Unlike most products, reusable bags are not designed for obsolescence. Because of this, purchasing a few reusable grocery bags and reusable produce bags should not be a big hit to your finances. 

If you are fine with simplicity, a one-time expenditure of $20-$30 can set you up with several bags that can last for decades. Even if you desire a fancier bag, the cost certainly shouldn't leave you struggling to pay your bills. In the long run, you may even save money as some grocery stores reward customers who bring their own shopping bags with a small discount (usually five cents per bag).

Compostable Produce Bags Can Contaminate Recyclables

Another drawback of compostable produce bags is that many people do not dispose of them properly. These bags often end up in landfills or enter the recycling system. When compostable packaging breaks down in a landfill, it adds to methane produced by the other organic material. When these bags enter the recycling system, the consequences are even worse, as they can contaminate a whole batch of recyclable material.

Introducing compostable materials into people's everyday lives will only help so much. Consumers also need to be educated about these products. Proper disposal of compostable produce bags is an essential step in the process of making these products a truly better alternative.

The World Is Changing: We Have to Adapt

Compostable produce bags are just one of several innovations focused on sustainability that we have seen grow in popularity over the past several years. The danger posed by climate change has become more pronounced as we continue to see more and more of the effects on our planet each year. People around the world are finally taking notice of the warnings that environmentalists have been making for decades.

Unfortunately, since it took so long for most people to acknowledge these warnings, we have gotten ourselves into a very dangerous position. Even now, many still ignore these issues. While among those who have begun to pay attention, many behaviors persist that are counter to sustainability. 

We need to all look at our lives and assess the ways in which we can reduce our carbon footprint. We need to look at the areas in which we can improve and also at all of the different options within those areas. Choosing a compostable bag at the grocery store is certainly better than using a plastic one. However, buying a reusable canvas tote and bringing it with you each time you shop is the best option.

Compostable Produce Bags Are a Good Starting Point

Compostable bags are a move in the right direction, and stores that have swapped out their plastic bags for these more eco-friendly alternatives should be commended. However, they are just a small step and one that, like so many of the products we use today, will hopefully soon be obsolete. 

Compostable produce bags are a short-term solution to a long-term problem. Our real focus needs to be eliminating single-use bags altogether. For centuries reusable bags and baskets were the standards, and single-use options were nonexistent. While innovation often leads to progress, there are certainly instances where humanity has taken a misstep.

We once functioned without single-use bags, and we can do it again. To prepare for the future, we must sometimes look to the past. We need to get back to basics and make forward-thinking choices, rather than focusing on what is the most convenient option for the moment. Our planet and children will appreciate the small sacrifices we make to get the world back on track.
