This article examines the environmental, economic, and public-health implications of menstrual hygiene products within a One Health perspective, highlighting how individual choices can contribute to sustainability. Menstrual products—used monthly for roughly 40 years of reproductive life—generate significant waste due to their widespread use and high plastic content. Historically, menstrual management evolved from rudimentary natural materials to industrial products shaped largely by male-driven design choices, leading to a proliferation of disposable items with heavy reliance on plastics, applicators, and individualized packaging. Today, most disposable pads and tampons contain multiple plastic components, contributing substantially to non-recyclable waste. In Italy, absorbent hygiene products account for about 3% of total non-recoverable waste—approximately 900,000 tonnes per year. Growing awareness has led to increasing interest in sustainable alternatives such as menstrual cups, absorbent washable underwear, reusable cloth pads, biodegradable pads, and, to a lesser extent, sea-sponges, though the latter raise hygiene and ecological concerns. Political initiatives, including reduced VAT on biodegradable or reusable menstrual products and local programs distributing menstrual cups and washable nappies to families, promote cultural and behavioral change. Economic analyses reveal that women use 10,000–14,000 pads or tampons over a lifetime, spending around €5,000, with “period poverty” affecting socially vulnerable groups lacking access to adequate products and sanitation. The article also addresses the environmental impact of condoms, widely used for contraception and STI prevention. Although essential for sexual health, condoms—whether latex or synthetic—are not compostable and must be disposed of as general waste. Their production involves significant environmental costs due to synthetic additives and small, non-recyclable aluminum or composite packaging. Overall, sustainable menstrual and sexual health practices require informed consumer choices, supportive public policies, improved product design, and accessible education on proper waste disposal.
