An ordinary supermarket could dispense thousands of carrier bags every day, not to mention those used for e-commerce, restaurants, and take-away snack foods. It’s not a concern if carrier bags made of traditional plastics are used very little daily, however, as time goes on, it’s now already become a major concern in people’s lives. Especially in the Garbage dump, people who saw it would never forget the hellish conditions. Without plastics, the general rubbish could decay immediately during the period bringing from the location of the dustbin to the Garbage dump.
Traditional plastic bags are now harming people’s lives, increasing the cost for governments and society to take care of garbage pollution, as well as causing problems that influence people’s health. To prompt the use of biodegradable carrier bags, we need to have a brief understanding of how it is and what benefits it would bring to people’s lives?
Biodegradable carrier bags are made from materials that can decompose naturally through the action of microorganisms, such as bacteria and fungi, under specific environmental conditions. Unlike conventional plastic bags, which can take hundreds of years to degrade, biodegradable bags break down into water, carbon dioxide, and biomass within a much shorter period. Common materials used in their production include cornstarch, polylactic acid (PLA), and polybutylene adipate terephthalate (PBAT).
Benefits of Biodegradable Carrier Bags
1. Reduced Environmental Impact:
Traditional plastic bags are notorious for polluting oceans, harming wildlife, and clogging landfills. Biodegradable bags, on the other hand, minimize these issues by decomposing naturally and leaving behind no toxic residues.
2. Renewable Resources:
Many biodegradable bags are made from plant-based materials like cornstarch or sugarcane, which are renewable and sustainable. This reduces reliance on fossil fuels, the primary raw material for conventional plastics.
3. Lower Carbon Footprint:
The production of biodegradable bags typically generates fewer greenhouse gas emissions compared to traditional plastic bags. Additionally, their ability to decompose reduces the long-term environmental burden.
4. Versatility and Functionality:
Biodegradable bags are just as durable and functional as traditional plastic bags, making them suitable for a wide range of uses, from grocery shopping to packing lightweight items.
Challenges and Considerations
While biodegradable carrier bags offer many benefits, they are not without challenges:
1. Decomposition Conditions:
Biodegradable bags require specific conditions, such as sunlight, oxygen, and microbial activity, to break down effectively. In landfills, where these conditions are often lacking, they may not decompose as quickly as expected.
2. Cost:
Biodegradable bags are generally more expensive to produce than traditional plastic bags. This cost is often passed on to consumers, making them less accessible to some.
3. Misconceptions and Misuse:
There is a common misconception that biodegradable bags can be littered without consequences. However, improper disposal can still harm the environment, and these bags should be disposed of responsibly.
4. Recycling Issues:
Biodegradable bags cannot always be recycled with conventional plastics, as they can contaminate the recycling stream. Clear labeling and education are essential to ensure proper disposal.
How to Use Biodegradable Bags Responsibly?
To maximize the benefits of biodegradable carrier bags, it’s important to use them responsibly:
- Dispose of them properly: Use designated composting facilities or follow local waste management guidelines.
- Reuse them: Just like traditional plastic bags, biodegradable bags can be reused multiple times to extend their lifespan.
- Educate others: Spread awareness about the proper use and disposal of biodegradable bags to encourage broader adoption.
As technology advances, the production of biodegradable bags is becoming more efficient and cost-effective. Innovations in materials science, such as the development of fully compostable bioplastics, are paving the way for even more sustainable options. Governments, businesses, and consumers all have a role to play in promoting the use of biodegradable bags and reducing plastic waste.
Biodegradable carrier bags are a step in the right direction toward a more sustainable future. While they are not a perfect solution, they offer significant environmental benefits compared to traditional plastic bags. By choosing biodegradable bags, using them responsibly, and supporting sustainable practices, we can collectively reduce our environmental footprint and protect the planet for future generations. Every small change counts and biodegradable bags are one way to make a big difference.
Let’s embrace this eco-friendly alternative and work together for a greener, cleaner world! 🌱
