Design Specifications

Biodegradable material of banana tree fiber, with plant-based plastics and banana fibre Absorbency level is almost double what current standards asks for.^{Interview with representative} Indian government established standard for absorbency; Saathi pads meet the standard for absorbency and nearly doubles what the standard asks for with the latest design.^{Interview with representative}

Expert comments on biodegradability: Polypropylene nonwovens, which are used for the cover and polyethylene films, which are used for the barrier are not biodegradable, neither are positioning adhesives (i.e. the adhesive to stick the pad to the underwear). Additionally, biodegradability per se does not mean that a product would actually biodegrade under all circumstances. Same as for compostability, the environment for degradation has to be right; e.g. PLA, a corn derived plastic is compostable in commercial hot composting facilities but would not decompose when littered.

Lifecycle

Up to 8 hours, though varies by woman based upon menstrual flow. Typically 4-6 hours of use. ^{Interview with representative}

Manufacturer Specified Performance Parameters

High absorbency capacity to ensure lifecycle is similar to other pads on the market, material is adhesive and thin enough for user comfort and ease, look and feel similar to standard pads, high absorbency level and capacity.

The designers are also aiming to encourage more awareness of sustainability and acceptance of the product. One goal is to make the pad locally accessible, both in the materials used and distribution chain. ^{Interview with representative}

Vetted Performance Status

The product has undergone extensive research and testing, both within India and also in MIT's D-Lab. The Saathi team has ensured that the pads follow government standards and may have plans to run clinical trials with interested gynecologists and other clinicians. ^{Interview with representative}

Compliance with regulations

Saathi follows government standards as set by the Bureau of Indian Standards for sanitary napkins (IS 5405).^{Interview with representative} Experts note that sanitary napkins have to meet the microbiological requirements of the governing body (expressed as a maximum bioburden, measured in CFU).

Evaluation methods

User testing and feedback, research experiments to ensure compliance with governmental standards.^{Interview with representative}

Other Information

Experts note that considering the sparsity of bathroom facilities (or other locations to change the pads outside the home) in India, it's recommended to design pads that can be used at least for 12 hours. The user can put on a pad in the morning and change it at night, both in the privacy of her home.
