Biodegradable” and “compostable” are two terms for environmentally friendly materials. These bags can replace traditional plastic. In the era of plastic reduction, these two materials are often considered eco-friendly product choices. While they may seem similar at first glance, they are actually quite different. This article will examine biodegradable vs compostable bin bags. For more details, see the article below!
The definition of Biodegradable vs Compostable Bin Bags
The first difference lies in the definition. Biodegradable means a material can be broken down by microorganisms under natural aerobic or anaerobic conditions indefinitely. Natural materials that can be biodegraded include wood, leaves, paper, and food waste. This means these trash bags are made from natural materials like cassava.
Meanwhile, compostable materials are defined as materials that can be broken down by microorganisms in a composting environment. These materials are converted into natural elements that are harmless to the environment, including carbon dioxide, water, and nutrients.
Since composting is done by humans, the temperature, humidity, and decomposition time of the materials can be controlled. Currently, many companies have obtained certification for their compostable trash bag products.
Differences Between Biodegradable and Compostable Bin Bags
Here are some of the differences between biodegradable and compostable bin bags:
Final Result
The final result of biodegradable vs compostable bin bags also differs. Biodegradable bags can leave behind harmful residues or microplastics. This, of course, depends on the raw materials. Compostable bags, on the other hand, produce non-toxic compost that is actually beneficial to the soil.
Decomposition Time
Turning to the decomposition time, there is no fixed standard for biodegradable bin bags. In fact, it can take a long time. Decomposition can occur in natural environments such as soil and water under certain conditions. Compostable bin bags, on the other hand, can decompose within a certain timeframe. For example, 90 days in a composting facility. However, decomposition requires special conditions, such as an industrial composting facility or a heated home composter.
Certification
The difference between biodegradable and compostable bin bags is also significant. Biodegradable trash bags don’t always require official certification. This is because standards and labeling requirements for “biodegradable” products vary across regions and even countries.
Compostable bin bags, on the other hand, must have official certification, such as OK Compost, to substantiate their product claims. This certification ensures that the “compostable” claim on the product packaging is true and can be independently verified by a trusted third party. Without certification, consumers have no assurance that the product will decompose properly.
Environmental Impact
Compostable bin bags offer several positive environmental impacts compared to conventional plastic bags, but their use also presents challenges and limitations. These products typically produce lower levels of carbon dioxide, a greenhouse gas, and can enrich the soil.
Biodegradable bin bags, on the other hand, can potentially produce methane and microplastics as they decompose. This poses significant environmental risks, especially if not properly managed in industrial facilities or specially designed landfills.
The main difference between biodegradable vs compostable bin bags lies in the final product and the rate of decomposition. Biodegradable means the waste can be broken down naturally by microorganisms, but it doesn’t necessarily convert to compost and can leave quite harmful residues. In contrast, compostable means the waste completely decomposes into compost (CO₂, water, and biomass) within a certain timeframe, for example, around 90 days without leaving any toxic residues, and requires specific composting conditions.
