What is the degradation process of Biodegradable Bags?

The degradation process of biodegradable bags involves the breakdown of these bags into simpler compounds through natural environmental processes. However, it's important to note that the specific degradation process can vary depending on the material and formulation of the biodegradable bag. Here's a general overview of the degradation process for biodegradable bags:

Exposure to Environmental Factors: Biodegradable bags are designed to break down when exposed to various environmental factors, such as sunlight, moisture, oxygen, and microbial activity. These factors initiate and accelerate the degradation process.

Hydrolysis: In the presence of moisture (water), the chemical bonds within the biodegradable bag's polymer chains begin to break. This process is called hydrolysis. Water molecules infiltrate the bag's structure, causing it to weaken and eventually fragment into smaller pieces.

Microbial Action: Microorganisms, such as bacteria, fungi, and enzymes, play a crucial role in the degradation of biodegradable bags. These microorganisms consume the bag's organic components as a source of energy, breaking down the polymer chains into simpler compounds. This microbial activity is especially important in natural settings where microorganisms are abundant.

Fragmentation: As the bag's polymer chains are broken down into smaller molecules, the bag gradually loses its structural integrity. This leads to the fragmentation of the bag into smaller pieces, which can further facilitate microbial and chemical degradation.

Conversion into Humus: The degraded components of the biodegradable bags can be converted into humus-like substances. Humus is a stable organic material that becomes part of the soil and can improve its quality. These substances integrate into the natural ecosystem without causing long-term environmental harm.
