Biomaterials are everywhere. From the packaging that wraps your food to the stitches used in surgery, these materials shape our daily lives. But not all biomaterials are created equal. Some break down naturally over time, while others stick around for centuries. This brings us to two main types: biodegradable and non-biodegradable biomaterials. The difference? Biodegradable ones decompose, leaving little to no waste. Non-biodegradable ones last much longer, but they can also lead to pollution. Let’s do a quick Visual Comparison of Biodegradable Vs. Non-Biodegradable Biomaterials.
In this article, we’ll compare these two types side by side, using simple explanations and visual comparisons to make things clear.
Let’s dive in!
Understanding Biomaterials
What are Biomaterials?
Biomaterials are materials designed to work with living systems. They can be natural (like collagen or silk) or engineered (like medical-grade plastics). These materials are widely used in medicine, packaging, construction, and even fashion.
Key Properties of Biomaterials:
- Safe for human or environmental contact
- Durable enough for their intended use
- Can be biodegradable or non-biodegradable
Did You Know?
The first recorded use of biomaterials dates back to 3000 BC, when ancient Egyptians used plant fibers, hair, tendons, and wool threads for surgical stitches!

Why Does Biodegradability Matter?
Not all biomaterials break down the same way. Some decompose naturally within weeks, while others linger in landfills for centuries. This makes biodegradability a key factor in reducing pollution and waste.
The Environmental Impact
🌱 Biodegradable biomaterials help reduce landfill waste and ocean pollution. For example, a banana peel decomposes in about a month, while a plastic water bottle takes 450 years!
The following image shows a Visual Comparison of Biodegradable Vs. Non-Biodegradable Biomaterials.
🚯 Non-biodegradable biomaterials contribute to long-term waste and microplastic pollution. The world produces over 400 million tons of plastic waste annually, much of which is non-biodegradable.
The Economic Impact
💰 Industries are shifting towards biodegradable materials to cut waste disposal costs and meet sustainability goals. The biodegradable plastics market alone is projected to hit $23 billion by 2026!
Quick Thought:
If more companies switch to biodegradable materials, could we see a world with less plastic waste?
Biodegradable Biomaterials: Definition & Characteristics
A biodegradable biomaterial is a material that naturally breaks down over time with the help of microorganisms like bacteria and fungi. These materials decompose into water, carbon dioxide, and organic matter, leaving behind little to no waste.
The speed of decomposition depends on the material type and environmental conditions like temperature, moisture, and microbial activity. Some biodegradable materials break down in weeks, while others may take several months.
Real-Life Example: A paper bag decomposes in about 6 weeks, while a plastic bag can take up to 1,000 years!
Key Characteristics of Biodegradable Biomaterials
Decomposes Naturally – Microbes break it down into harmless substances.
Leaves Minimal Waste – Reduces pollution and landfill waste.
Sourced from Renewable Resources – Often made from plants, algae, or biopolymers instead of fossil fuels.
Examples of Biodegradable Biomaterials
1. Polylactic Acid (PLA)
What is it? PLA is made from fermented corn starch or sugarcane.
Where is it used? Food packaging, 3D printing, medical implants.
Decomposition time? 6 months to 2 years in industrial composting conditions.
2. Starch-Based Plastics
What is it? Plastics made from corn, potato, or tapioca starch.
Where is it used? Disposable cutlery, bags, packaging materials.
Decomposition time? 3 to 6 months under the right composting conditions.
3. Chitosan & Alginate-Based Biomaterials
What is it? Chitosan comes from shrimp shells, while alginate is extracted from seaweed.
Where is it used? Wound healing, food preservation, water purification.
Decomposition time? Weeks to months, depending on moisture and microbial activity.
Did You Know?
PLA plastic can be composted, but it won’t break down in a landfill due to a lack of oxygen and high temperatures. This is why proper waste disposal is key!
Non-Biodegradable Biomaterials: Definition & Characteristics
Unlike biodegradable materials, non-biodegradable biomaterials do not break down naturally in a short time. Instead, they can persist in the environment for decades or even centuries.
These materials are usually made from synthetic polymers, which are engineered for durability. While this makes them valuable for medical, industrial, and packaging applications, it also leads to waste buildup and pollution.
🔍 Real-Life Example: A plastic water bottle made from polyethylene (PE) can take up to 450 years to degrade!
Key Characteristics of Non-Biodegradable Biomaterials
❌ Long Lifespan – These materials can last years to centuries before breaking down.
⚠ Leads to Waste Accumulation – If not recycled, they contribute to landfills and ocean pollution.
🔬 High Durability – Ideal for medical implants, industrial applications, and everyday products.
Examples of Non-Biodegradable Biomaterials
1. Polyethylene (PE)
What is it? The most common plastic, used in grocery bags, bottles, and food containers.
Where is it used? Packaging, pipes, medical tubing.
Decomposition time? Up to 500 years in landfills.
2. Polypropylene (PP)
What is it? A tough plastic used in straws, bottle caps, and furniture.
Where is it used? Automotive parts, medical devices, textiles.
Decomposition time? 20 to 30 years, but remains as microplastics.
3. Silicone-Based Biomaterials
What is it? A synthetic material made from silicon, oxygen, and carbon.
Where is it used? Medical implants, prosthetics, cookware, electronics.
Decomposition time? Hundreds of years, but some medical-grade silicones are reusable and recyclable.
Did You Know?
Over 90% of all plastics ever produced still exist today in some form—either in landfills, oceans, or as microplastics in the environment!
