Seattle Public Utilities' waste-pumping program has cut sewage spills from homeless people's RVs in half

Billions of people around the world lack access to safe sanitation, causing disease and deaths. In Ecuador a foundation developed a cheap, dry, composting toilet for poor rural families.

The Flint crisis displayed the deficiency of knowledge by medical doctors to environmental health concerns. In response, the national medical community is bringing more awarenesses and education to current and future doctors about the importance of long-term effects of the environment on health. More research in this area is necessary as well as more classes in medical schools. Universities across the U.S. are now developing such courses to change the future of patient care and crisis prevention.

Uganda’s education ministry requires all schools to have incinerators to burn used sanitary pads. Lack of funding limits schools’ ability to comply. Even when incinerators exist, girls don’t necessarily use them. Educating both girls and boys about menstruation reduces stigma and increases the likelihood that girls feel comfortable enough to collect pads instead of throwing them in pit latrines.

The simple addition of adding handles to bathroom stalls in the Rohingya refugee camps in Bangladesh has helped the camps' pregnant women regain a sense of empowerment and dignity. Providing support and balance, the design of these latrines have benefited the elderly in the camps as well.

A company based in Addis Ababa makes water filtration systems that simultaneously help rural and urban dwellers have access to clean water as well as keep the entire supply chain within Ethiopia. Despite challenges faced by the company to make a profit, the business is determined to keep economic growth centered in local communities rather than outsource production.

On World Toilet Day in 2014, the Kenyan government promised to build 180 public toilets in an ambitious move to combat the issue of public sanitation. The program went well once the keys were handed off to the National Youth Service of Kenya as a means of income, but issues quickly arose that could not be resolved because of a lack of further funds. The youth has since transformed their toilets into a rental space for local churches, such as Christ Miracle Church for All Nations in Laini Saba.

Amager Bakke is a powerplant in Copenhagen that is designed to get residents of the city engaged in a conversation about where waste goes, all while burning up to 400,000 tons of waste a year, powering 60,000 homes, and heating 160,000 homes. In 2013 the local plant was redesigned to burn the city's waste and encourage interaction by building a ski slope atop the plant, a hiking trail, and an elevator that introduces education about waste management. Amager Bakke is still new and experimental, so its long-term success is still unclear, and it is not completely emission-free yet.

As the Ogallala Aquifer’s water level has declined in many states across the High Plains region of the U.S., Nebraska has almost fully maintained its water level by relying on National Resource Districts (NRDs). NRDs “develop integrated management plans for surface water and groundwater,” and its sustainable practices offer a model of how sustainable water management can thrive with local governance.

The state of Pennsylvania set to plant 86,000 hectares of riparian buffers, the practice of planting trees and shrubs along a river or stream to filter water. Other benefits of riparian buffers include things like restoring the soil and cooling the water. In order to meet their goal, the state scientists used a bottom approach, enlisting the help of local farmers by offering them grants to plant trees and showing farmers how they can profit off of riparian buffers. While the state is behind its goal, the state is planting about 1,000 to 2,000 hectares a year.

In 2020, a devastating explosion in Beirut that came from a warehouse released 800,000 and one million tons of construction and demolition waste and 20,000 tons of shattered glass into the city. The waste was being thrown into landfills. However, landfills are notoriously bad for the environment. Out of that rubble an idea was created; disposing waste sustainably. Rubble Mountains was created specifically to do this. They've been able to restore four quarries, use materials to create public amenities, and diverting up to 50 tons of demolition waste from landfills.
