Plastic bags have been a part of our lives for decades because they are convenient and easy, but their effects on the environment are very alarming. These days, we use plastic at every step of life. We use plastic without concern from morning to night. Our toothbrush, shampoo bottle, milk, and in many products, plastic uses. Materials made with plastic pollute our land, clog our waterways, and take hundreds of years to decompose.

However, there are various eco-friendly alternatives available, and each has its own benefits along with its own degradation’s process. Let’s take a look into these alternatives, see how they degrade biologically, and why they’re better for the planet than those traditional plastic bags. Some countries, like California, ban single-use plastic bags.

5 Eco-Friendly Alternatives

1. Cloth Bags (Cotton and Jute Bags)

Why Choose Cloth Bags?

Cotton or jute bags consist of natural fiber. Help of these fibers, making them sturdy, reusable, and environmentally friendly. They are used for shopping and carrying groceries and produce because they are very durable. These bags were even washed and reused many times, which makes them sustainable as well.

How Do Cloth Bags Degrade?

These bags made of cloth are biodegradable because they have natural fibers easily broken down in the soil by microorganisms. Here is how it happens:

1. Cotton Bags

• Cotton has cellulose in it mainly as a carbohydrate; microorganisms that include fungi and bacteria eat these.
• With some moisture and oxygen, the cotton bag decomposes to carbon dioxide, water, and organic matter.
• This process takes 1–5 years under natural conditions but may be faster under composting environments.

1. Jute Bags:

• The jute fibers, like the burlap fibers, are full of cellulose and lignin. The microorganisms feed upon these components and totally break them within 5–6 months, given ideal conditions of composting.

Benefits of Cloth Bags:

• No harmful residues are left after throwing it.
• They are durable and also last for years if we maintain them well.
• Cotton bags reduce dependence on single-use plastic.

2. Paper Bags

Why we Choose Paper Bags?

Paper bags are light weighted, biodegradable, and recyclable. They are manufactured from renewable sources such as wood pulp and are applied to packaging, groceries, and takeaways. These are easy to make. We can reuse newpaper for making paper bags.

How Do Paper Bags Degradate?

Paper bags degrade or decompose much faster than others because of their organic nature.

• Paper is made from trees. When paper starts to deteriorate, bacteria and fungi eat away all the cellulose fibers in the paper.
• Paper bags decompose into carbon dioxide, water, and humus within 2–5 months when subject to soil, water, and oxygen.

Mechanism of Decomposition:

How Decomposition Takes Place:

Step 1: Hydration: Firstly Water makes paper soft due to the presence of cellulose fibers.

Step 2: Action by Microorganisms: Microorganisms produce enzymes that break down cellulose into compounds such as glucose.

Step 3: Final Decomposition: The glucose is further utilized by microbes, and carbon dioxide and water are produced as side products.

Advantages of Paper Bags:

• It is highly biodegradable and compostable in industrial and home composting systems.
• Paper bags are recyclable and renewable.
• It can reduce plastic pollution.

But paper production is resource-intensive. When making paper bags, loads of water and energy are needed. This paper bag can also be made from recycled paper bags.

3. Biodegradable Plastic Bags (Plant-Based Bags)

Why Choose Biodegradable Plastic Bags?

Biodegradable plastic bags can also be manufactured using natural resources such as cornstarch, cassava, sugarcane, tree pulp, bamboo fiber, polylactic acid (PLA), etc. They resemble the plastic but are biodegradable.

How Do Biodegradable Plastic Bags Biodegrade?

Biodegradable plastic bags degrade faster than traditional plastic bags we use on a daily basis. It is because biodegradable plastic is destined to degrade by microbes in the environment. It involves several steps for the degradation:

• hydrolysis: in the first step, the chemicals of the bags break down into small pieces when it comes to content with water molecules.
• Microbial Degradation: The microbes use the smaller piece to produce carbon dioxide, water, and biomass.
• The end products are non-toxic and environmentally safe.

Mechanism of Degradation:

• Starch-Based Bioplastics: Microbes break the starch to simpler sugars like sucrose fructose, and microbes metabolize those sugars further into carbon dioxide and water.
• PLA Bags: Polylactic acid first goes through hydrolysis, then it breaks down to lactic acid. Microbes feed on this.

Advantages of Biodegradable Plastic:

• The decompose takes months to some years, depending on the composting conditions.
• They are less harmful to wildlife and ecosystems than usual plastic.
• Compostable varieties add nutrients to the soil.

However, they often need industrial composting facilities in order to degrade fully and may not decompose well in landfills.

4. Reusable Mesh or Net Bags

Why Choose Mesh Bags?

Mesh bags are made from cotton or hemp. They are lightweight and breathable. Thus, mesh bags are very appropriate for fresh produce. The bag is also reusable and can be washed to decrease the amount of disposable bags used.

How Do Mesh Bags Degradate?

Mesh bags degrade naturally as cloth bags because they are composed of organic fibers. This is how it happens:

• Moisture Absorption: when fibers absorb water.It became softened and broke the structure.
• Microbial Action: The microorganisms absorb the broken piece (organic matter), leaving behind water, carbon dioxide, and organic residue.

Benefits of Mesh Bags:

• Mesh bags are completely biodegradable and leave no toxic residues.
• Encourage sustainable practices and reduce single-use plastic.
• Lightweight and easy to carry.

5. Bamboo and Palm Leaf Bags

Why Choose Bamboo or Palm Leaf Bags?

These bags are made of dried palm leaves or bamboo fibers and are an excellent eco-friendly alternative. They are mostly handcrafted, fashionable, and long-lasting.

How Do Bamboo and Palm Leaf Bags Degrade?

Bamboo Bags:

• Bamboo fibers contain a high amount of cellulose and lignin that is readily consumed by microbes.
• Bamboo bags decompose completely within 2-3 months under composting conditions.

Palm Leaf Bags:

• Palm leaves decompose much faster, and the process takes 6–8 weeks in a composting setup.

Benefits of Bamboo and Palm Leaf Bags:

• They decompose much faster than synthetic materials.
• They are nutrient enriching when composted.
• They help local artisans and promote sustainable livelihoods.

Why Are Plastic Bags Non-Biodegradable?

Plastic bags are manufactured from polymers, such as polyethylene, which are based on petroleum and have a long chain structure that microorganisms cannot decompose. Here’s why they don’t go away:

• Chemical Stability: The polyethylene has an intrinsically resistant chemical and biologic structure.
• Fragmentation: After hundreds of years, plastic bags ultimately break into microplastics because of physical forces like sunlight and wind, but they stay in the environment for hundreds of years.

Environmental Impact of Plastic Bags:

• Harmful to wildlife because animals mistake them for food.
• Pollute soil and waterways, disrupting ecosystems.
• Release toxic chemicals when burned, contributing to air pollution.

How Do Alternatives Compare to Plastic Bags?

The pollution and devastating effects on the environment can be minimized by using eco-friendly alternatives such as cloth, paper, or plant-based bags. These alternatives are biodegradable and make people adopt other sustainable habits like recycling and composting. For better understanding and knowledge of how these materials break down, their benefits over using plastic bags that take up to hundreds of years to decompose and leave toxic residues are pinpointed.

Adopting these green options is the smallest step one can take to ensure that our earth is preserved for the future.
