The growing awareness about environmental pollution and plastic waste has significantly increased the demand for sustainable alternatives across industries, including the menstrual hygiene sector. Traditional sanitary napkins are composed of plastics and synthetic materials that can take hundreds of years to decompose, contributing to serious ecological issues. As a result, biodegradable sanitary napkins have emerged as a promising and eco-friendly alternative. These napkins are not only safe for the environment but are also better for the skin, reducing the risk of rashes and infections caused by synthetic materials.

Why Switch to Biodegradable Sanitary Napkins?

The need for biodegradable sanitary napkins stems from the environmental damage caused by conventional pads. On average, a woman uses more than 10,000 sanitary pads in her lifetime. If each of these pads is made of plastic, the cumulative waste becomes alarming. Regular sanitary napkins consist of up to 90% plastic and take 500–800 years to degrade. These products often end up in landfills or are incinerated, both of which harm the environment.

On the other hand, biodegradable sanitary napkins are made using natural, organic, and compostable materials. They decompose much faster—usually within 6 months to 1 year—and cause no harm to the soil, water, or air. Moreover, they are chemical-free, making them safer for intimate use.

Key Materials Required

Creating biodegradable sanitary napkins involves using materials that are safe, absorbent, and environment-friendly. Here are the main components:

1. Absorbent Core

• Banana fiber: Derived from banana plants, this is a highly absorbent and renewable material.
• Bamboo fiber: Soft, antibacterial, and extremely absorbent.
• Cotton: Organic cotton is preferred for its softness and breathability.

1. Top Sheet (the layer in contact with the skin)

   • Non-woven organic cotton or bamboo fabric.

   • Cornstarch-based film can also be used to enhance comfort.

2. Back Sheet (leak-proof layer)

   • Made from biodegradable bio-plastic or cornstarch film.

   • Must be water-resistant but compostable.

3. Adhesives

   • Natural, non-toxic glue or plant-based gum for holding the layers together.

4. Packaging

   • Recycled paper or biodegradable plastic wrappers.

Step-by-Step Process to Make Biodegradable Sanitary Napkins

Step 1: Collect and Prepare Materials

Ensure that all raw materials, especially cotton or banana fiber, are clean and free from any harmful substances. If you are using natural fibers like banana or bamboo, they need to be dried and processed into soft, fluffy fiber.

Step 2: Form the Absorbent Core

Card the fibers (like banana, bamboo, or cotton) into a consistent sheet using a fiber carding machine or manually. The thickness of the sheet will determine the absorbency level. The sheet should be thick enough to absorb menstrual flow effectively.

Step 3: Layering

Layer the absorbent core between a soft top sheet and a waterproof biodegradable back sheet. Ensure all layers align properly and there are no gaps. This step is crucial for maintaining the structure and functionality of the biodegradable sanitary napkins.

Step 4: Shaping and Cutting

Using a template, cut the layered sheets into the desired shape and size. Typically, sanitary napkins are around 240 mm in length. Different sizes can be made to suit varying flow levels.

Step 5: Sealing the Edges

Use heat or pressure sealing (if you have the equipment) or stitch the edges with biodegradable thread. This step helps hold the pad together and prevents leakage.

Step 6: Adding Adhesive

Apply non-toxic, plant-based adhesive on the back sheet to help the pad stick to the underwear. Allow it to dry completely before packaging.

Step 7: Sterilization

This step ensures hygiene and safety. Sterilize the pads using UV light or steam. This eliminates any bacteria or microbes that may be present.

Step 8: Packaging

Pack each pad individually using biodegradable paper or plastic. Proper labeling can also include manufacturing date, expiry date, and disposal instructions.

Advantages of Making Biodegradable Sanitary Napkins

1. Eco-Friendly
   These pads reduce landfill waste and pollution. They decompose naturally, contributing to a healthier planet.

2. Safe for Health
   Made from organic and chemical-free materials, they reduce the risk of rashes, infections, and allergies.

3. Entrepreneurial Opportunity
   There is growing market demand, especially in rural and semi-urban areas. Low-cost production units can be set up with minimal investment.

4. Support for Women’s Health
   Community-based production of biodegradable sanitary napkins empowers local women by providing jobs and promoting menstrual hygiene awareness.

5. Government and NGO Support
   Many governments and NGOs provide subsidies and support to initiatives that promote eco-friendly menstrual hygiene products.

Market Potential and Demand

The global biodegradable sanitary napkin market is growing rapidly, driven by increased awareness and environmental regulations. In countries like India, where the government actively promotes menstrual hygiene programs, the potential is huge. Urban consumers are also shifting toward sustainable living and are willing to pay a premium for eco-friendly products. Moreover, bulk orders from schools, offices, and NGOs provide a stable business opportunity.

Challenges in Production

Despite the benefits, there are some challenges in the production of biodegradable sanitary napkins:

• Raw Material Sourcing: Quality organic materials can be hard to find in some regions.
• Short Shelf Life: Being natural, the pads have a limited shelf life and may degrade faster in humid conditions.
• Cost: Initial production cost may be higher compared to conventional pads, although this is gradually reducing with scale.
• Consumer Awareness: Many consumers are unaware of the advantages of biodegradable products, which necessitates ongoing education and marketing efforts.

Tips for Starting a Small-Scale Unit

1. Conduct Market Research: Understand the demand, competition, and customer preferences in your area.
2. Choose the Right Equipment: Semi-automatic machines are ideal for small units and can produce 1,000–2,000 pads per day.
3. Train Your Staff: Ensure your team understands hygiene, quality control, and sustainability standards.
4. Branding and Marketing: Create a strong brand identity highlighting the eco-friendly and health-safe aspects of your product.
5. Get Certifications: Obtain eco-certifications and health approvals to gain consumer trust.

Environmental and Social Impact

Producing and using biodegradable sanitary napkins contributes to multiple Sustainable Development Goals (SDGs), including gender equality, good health and well-being, and responsible consumption. It addresses environmental degradation while also empowering women with employment and hygienic menstrual practices.

Conclusion

The future of menstrual hygiene lies in sustainability, and biodegradable sanitary napkins are a vital part of this shift. By choosing to manufacture or use these eco-friendly alternatives, we can protect the planet while promoting better health and dignity for women. Whether you’re an entrepreneur seeking a meaningful business opportunity or an individual looking to make environmentally responsible choices, biodegradable sanitary pads offer a solution that aligns health with sustainability.

As awareness and accessibility improve, the use of biodegradable sanitary napkins is expected to become mainstream—transforming lives and landscapes, one pad at a time.
