Flora & Fauna

Soil microbial communities
Accumulation of microplastics and chemical additives (such as transition metal salts of cobalt or manganese) from oxo-degradable plastics alters soil biophysical properties and disrupts microbial activity.
Aquatic fauna
Microplastics fragmented from oxo-biodegradable waste enter aquatic ecosystems, causing ingestion hazards, physical blockages, and bioaccumulation of toxic chemicals in the food web.

Ecology Impact

The disposal of approximately 12.3 billion sanitary napkins annually in India, classified as domestic hazardous waste under the Solid Waste Management Rules, 2016, poses a severe landfill and pollution challenge. The use of oxo-biodegradable plastics, which fragment into microplastics rather than fully decomposing, threatens terrestrial and aquatic ecosystems by accumulating in soil and water bodies.

Science & Tech Angle

Oxo-biodegradable plastics are conventional polyolefins blended with pro-oxidant transition metal additives that accelerate abiotic oxidative degradation under UV light and heat. However, ASTM D-6954 is a standard guide for testing and does not guarantee complete biological mineralisation, often resulting in persistent microplastics rather than true biodegradation.

Climate Change Link

Traditional sanitary pads contain up to 90% petrochemical-based plastics, contributing to fossil fuel extraction and carbon emissions during manufacturing and high-temperature incineration. Transitioning to truly compostable, plant-based alternatives supports India's climate commitments under the Paris Agreement by reducing the carbon footprint associated with single-use plastic production and waste management.

Sustainable Development

The provision of sustainable menstrual hygiene products directly supports SDG 6 (Clean Water and Sanitation) and SDG 12 (Responsible Consumption and Production) by promoting biodegradable alternatives over single-use plastics. It also advances SDG 5 (Gender Equality) and SDG 4 (Quality Education) by preventing school dropouts among girl students without compromising environmental sustainability.

International Frameworks

Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal
The 2019 Plastic Waste Amendments regulate the transboundary movement of non-recyclable plastic waste, emphasizing the need for environmentally sound domestic management of plastic-containing sanitary waste.
United Nations Environment Assembly (UNEA) Resolution 5/14
This resolution mandates the development of an internationally legally binding instrument on plastic pollution, targeting the entire lifecycle of plastics, including the prevention of microplastic pollution from oxo-degradable materials.
