Title : From mill waste to menstrual dignity: A circular economy model for affordable, plastic-free menstrual hygiene in Peri-Urban Pakistan
Abstract:
BACKGROUND
Menstrual health and hygiene (MHH) access remains a critical public health challenge in Pakistan. A UNICEF cost analysis (2022) found that only 4 million of approximately 60 million women of reproductive age use commercial sanitary napkins meaning 56 million manage menstruation with reused cloth, rags, or other unhygienic materials associated with elevated reproductive tract infection risk. A 2024 UNICEF and WaterAid National MHH Monitoring Assessment confirmed that Pakistan has no national menstrual health policy and MHH is absent from provincial WASH and education budgets. Simultaneously, every commercial pad available in the Pakistani market contains sodium polyacrylate (SAP) a petrochemical plastic polymer classified under EU REACH microplastics regulations that persists in landfill for 500–800 years and is pressed against women’s most sensitive mucosal tissue for hours at a time.
OBJECTIVE
To demonstrate that a commercially viable, circular economy manufacturing model can simultaneously address MHH affordability barriers for peri-urban women in Pakistan and eliminate petrochemical plastic from the absorbent core of sanitary napkins without subsidy or donor dependency for ongoing operations.
METHODS
Kamfit, a Karachi-based social enterprise, developed Mill-Origin Cotton Cellulose™ (MOCC) an absorbent core manufactured from pre-consumer cotton fibre recovered from Pakistan’s textile mill waste stream replacing bleached paper pulp and eliminating SAP entirely. The product is distributed through a PSI Europe-validated community agent network in peri-urban Karachi, using female agents from within target communities. Impact is measured across five pillars: trees saved, water saved, plastic eliminated, landfill diverted, and GHG avoided. A Gold Standard carbon credit project is in preparation across three verified emission reduction mechanisms.
RESULTS
At 50,000 pads per day, the Kamfit model eliminates 36.5 tonnes of SAP plastic annually, avoids 223.7 tonnes of CO2eq per year, saves 4.93 million litres of water, and diverts 127.75 tonnes from landfill. PSI Europe programme validation confirms community uptake and improved MHH outcomes among women previously relying on cloth. Distribution has expanded to four peri-urban Pakistani cities targeting 150,000 women reached cumulatively by October 2026. Because MOCC sourcing costs less than imported paper pulp and SAP, the product is priced accessibly without subsidy demonstrating that the environmental and affordability missions are structurally the same manufacturing decision.
CONCLUSION
The MOCC model proves that plastic-free, body-safe menstrual hygiene can be manufactured affordably at commercial scale using circular industrial waste inputs. This approach addresses the dual failure of the conventional market exclusion of low-income women and environmental harm within a single commercially self-sustaining model. The findings have implications for MHH policy, feminine hygiene manufacturing standards, and circular economy frameworks across South Asia.
