With ever-improving social and medical awareness about menstrual hygiene in India, the demand for sanitary napkins has increased significantly. The utilization of high-quality and environment-friendly raw materials to produce these pads is further supporting the growth of the market. However, with improving demand and usage, the need for proper disposal techniques becomes more relevant, since all of these pads get contaminated with human blood which makes them a biohazard and can cause significant damage to human health and the environment. One sanitary pad takes around 800 years to degrade naturally and the plastic and super absorbent polymers (SAPs) in sanitary pads are non-biodegradable and can take multiple decades to degrade. Waste management technologies such as pyrolysis, gasification, and resource recovery can be adopted to manage tons of sanitary waste. Currently, sanitary waste treatment mainly focuses on landfilling, incineration, and composting, where biohazard wastes are mixed with tons of solid waste. Disposable sanitary pads have a high carbon footprint of about 5.3 kg CO2 equivalent every year. Innovative solutions for sanitary pad disposal are discussed in the manuscript which includes repurposing of derived waste cellulose and plastic fraction into value-added products. Future aspects of disinfection strategies and value addition to waste cellulose recovered from napkins were systematically discussed to promote a circular economy.

BACKGROUND: From menarche until menopause, the average menstruator will use over 11 000 tampons or sanitary pads. Vaginal and vulvar tissue is highly permeable, and chemicals are absorbed without undergoing first-pass metabolism.
OBJECTIVE: To conduct a review of the literature to determine exposure to environmental chemicals in menstrual products.
METHODS: This review identified 15 papers over the past 10 years.
METHODS: Papers that measured chemicals in menstrual products and that measured human biomarkers of chemical exposure were included. Papers had to also be available in English.
METHODS: Reviewers assessed the articles and data provided. Multiple chemical groups were found.
RESULTS: Phthalates, volatile organic compounds, parabens, environmental phenols, fragrance chemicals, dioxins and dioxin-like compounds were detected in menstrual products. Research gaps were identified, including the lack of studies on newer products such as menstrual underwear and cups/discs. In addition to measuring chemicals in these products, future research should focus on clarifying the exposure per menstrual cycle to these chemicals to understand how menorrhagia and cycle length influence exposure from menstrual products.
CONCLUSIONS: Menstrual products contained measurable levels of a range of endocrine disrupting chemicals including phthalates, phenols and parabens. This reflects a potentially important route of exposure to chemicals that can impact women\'s reproductive health.

Many adolescent girls in Ethiopia and elsewhere missed school during their monthly cycles due to a lack of affordable menstrual absorbent materials or money to buy sanitary pads. So far, few studies have looked into the relationship between earning pocket money and maintaining good menstrual hygiene. Hence, this systematic review and meta-analysis aimed to synthesize the best available evidence regarding the association between earning pocket money and menstrual hygiene management among adolescents in Ethiopia.
We systematically searched PubMed, Hinari, Science Direct, Cochrane Library, ProQuest, POPLINE, African Journal Online, Direct of Open Access Journals, and Google Scholar for studies examining the association between earning pocket money and menstrual hygiene management among adolescent girls in Ethiopia, without restriction in a publication year. The Joanna Briggs Institute quality assessment tool for the cross-sectional studies was used to assess the quality of included studies. A prefabricated checklist, including variables: first author, publication year, sample size, type of questionnaire, and the region was used to extract data from the selected articles. A random-effect meta-analysis model was used to estimate the pooled odds ratio (OR) of the association between earning pocket money and menstrual hygiene management. The heterogeneity and publication bias was assessed by using I2 test statistics and Egger\'s test, respectively.
Data from nine studies involving 4783 adolescent girls were extracted. The meta-analysis revealed that adolescent girls who earned pocket money from their parents or relative had 1.64 times higher odds of having good menstrual hygiene management than their counterparts [pooled OR = 1.64, 95% CI: 1.16-2.34, I2:66.7%, n = 7 (number of studies)]. Similarly, the likelihood of having good menstrual hygiene management was lower by 49% among adolescent girls who did not receive any pocket money from their parents compared to their counterparts (pooled OR = 0.51, 95% CI: 0.35-0.74, I2:48.4%, n = 2).
The findings revealed that adolescent girls who earned pocket money were more likely to practice good menstrual hygiene management. Progress toward better menstrual hygiene will necessitate consideration of this factor.
