A little over 10 years ago, while teaching English in northern Cambodia, Samir Lakhani had a soap epiphany. “I saw a village mom bathing her newborn kiddo, but unfortunately, she was scrubbing him with laundry powder, which can be quite harmful to the skin.” It was all the mother had to use.  According to UNICEF, 2.3 billion people around the world do not have handwashing facilities with running water and soap available at home. This has consequences. It’s estimated that the simple act of using soap to wash hands, for example, can prevent up to one million deaths and can reduce the risk of respiratory illnesses by up to 21 percent in both children and adults. What Lakhani witnessed in Cambodia changed his life. “Ever since I have wanted to work in soap and to connect people with proper soap,” he says. He came up with a smart but simple idea: rescue used soap from hotel trash bins and deliver it to communities where it could save lives.

It’s estimated that globally, five million hotel soap bars are tossed every day. Ending up in the landfill, they join a melee of other products emitting harmful greenhouse gases, such as methane, into the atmosphere. Many of the oils used in the manufacture of soap are biodegradable, but when added to a compacted pile of trash and deprived of air, they do not decay quickly. Some soaps also contain dyes or phosphates that are not naturally decomposable. In 2014, Lakhani founded Eco-Soap Bank, which has since diverted over 14 million pounds of soap from landfills around the world. In its early years, Eco-Soap built a global network of more than 1,000 hotels to intercept this waste. Then came the pandemic, and many of those hotels shut down as people stopped traveling. “We needed to find another source of soap to recycle, and we began to reach out to soap factories,” Lakhani says. “We uncovered a dirty truth.” Annually, about a quarter-billion bars of soap go directly into landfills because of small manufacturing or aesthetic defects that make them unsellable.  Weighed down by negative news?

In Australia, the nonprofit organization Soap Aid collects, sorts, cleans and reprocesses soap from accommodations across Australia and New Zealand into fresh, hygienic soap bars. These soap bars are then redistributed to communities in need throughout the southern continent and the world. Since its inception in 2011, the organization has kept over 380 metric tons of soap out of landfills. A worker sorts soap for Soap Aid.

In Canada, Soap for Hope, based in Victoria, British Columbia, also upcycles soap but uses less rigorous methods. “Bacteria doesn’t grow on soap,” notes the organization’s founder, C. Anne McIntyre. The soap bars received by Soap for Hope are hand-scraped by the organization’s battalion of volunteers, who also sort and repurpose other materials like old hotel linens and amalgamate new bottles of shampoos and conditioners from half-used ones rescued from hotels throughout British Columbia and Alberta. As with Lakhani, it all started when McIntyre had her soap epiphany in 2015. “I used to do international aid and we were sending soap overseas with disaster kits, and [it] just seemed very obvious that people needed that,” she says. However, the liquid amenities such a shampoo sometimes received with the donations of soap could not be sent overseas. McIntrye took it upon herself to take those products to shelters in Victoria. “They were ecstatic to receive it,” she recalls. This joy at receiving a simple bottle of shampoo made her realize that her own community also lacked access to hygiene products. She decided to do something about it. Flash-forward to 2025, and McIntyre has built partnerships with regional hotel chains such as the Fairmont and Marriott, and the nonprofit provides hygiene products to over 500 community service organizations in British Columbia and Alberta. In 2024, Soap for Hope worked with hotels to divert nearly 6,500 pounds of waste from landfills.

According to Caitlen Creaney, food program and participant engagement coordinator, mothers will forgo things such as scented body wash or skin care for themselves to stretch the budget and make sure their children have what they need. This, though, can have dire consequences. In January 2025, Soap for Hope sponsored Canada’s first Hygiene Poverty Survey. Polling their database of service organizations in British Columbia and Alberta, almost 98 percent of respondents reported that their clients experienced negative mental health outcomes, including stress, anxiety and depression, due to hygiene inequity. In addition to basic hygiene products like soap, Soap for Hope also offers body washes and skin care products. Many are collected from hotels, and others from community drives in which bins are set up in local malls and the general public is invited to drop off donations of unused or half-used hygiene products. According to McIntyre, receiving body wash, moisturizer or even shaving lotion goes a long way in helping to restore an individual’s sense of dignity, health and self-confidence.  At Soap for Hope, the motto “nothing goes to waste” extends beyond soap to include the plastic containers that once housed body wash, shampoo or conditioner. Containers that can’t be repurposed by Soap for Hope are sent to a recycling depot, which grinds the plastic down into filaments that can be embedded into cement to make it more durable.

There was, as she points out, little awareness about hygiene waste or the environmental cost of discarded hotel soap. It’s only in recent years that the conversation around sustainability and corporate social responsibility has emerged. In the beginning, according to O’Leary and Carol Bellew, Soap Aid’s general operations manager, just setting up a recycling plant was a significant achievement. Most commercial soap machinery is designed to work with uniform, factory-grade inputs. Recycling bars that vary in size, brand, texture and condition requires fine-tuning. The machinery was sourced from multiple manufacturers and had to be tested multiple times to make sure it could do the job. McIntyre also admits that fundraising to keep Soap for Hope solvent is difficult, especially during economic downturns when, traditionally, donations go down but needs go up. But perhaps her biggest challenge has been proving to the skeptics that she could bridge the gap between sustainability and hygiene inequality. “I can’t tell you how many people told me I was so crazy when we started,” she says. “But it just made such perfect sense to me. Everyone needs soap.” The post What Happens to Leftover Hotel Soap? appeared first on Reasons to be Cheerful.
