Landfills are designated areas for waste disposal buried under layers of soil. Under the best circumstances, landfill operators manage waste safely and efficiently, minimizing environmental and human health impacts. Despite best intentions, landfills can pose significant environmental and health hazards.
Water Contamination
One of the most critical dangers of landfills is the potential for water contamination. Landfills generate leachate, a liquid that forms when rainwater filters through waste material. This leachate can contain hazardous substances, including heavy metals, organic compounds, and pathogens. If not adequately managed, leachate can seep into the soil and contaminate groundwater sources, which is crucial for drinking water and irrigation.
Air Pollution
Landfills are significant sources of air pollution. Organic waste decomposes anaerobically (without oxygen), producing landfill gas, primarily methane and carbon dioxide. Methane is a potent greenhouse gas, with a global warming potential 28-36 times that of carbon dioxide over 100 years. According to the Environmental Protection Agency (EPA), landfills are the third-largest source of human-related methane emissions in the United States. Other toxic gases and volatile organic compounds (VOCs) released from landfills can cause respiratory issues and other health problems for nearby communities.
Soil Contamination
The soil surrounding landfills can also become contaminated over time. Hazardous chemicals and heavy metals can leach from the waste and accumulate in the soil, posing risks to plant and animal life. These contaminants can enter the food chain. Research has shown that areas around landfills often have higher concentrations of heavy metals in the soil, affecting agriculture and local wildlife.
Impact on Wildlife
Landfills can significantly impact local wildlife. Birds and other animals are often attracted to landfills due to food availability. Consuming waste can lead to poisoning, malnutrition, and death. Landfills can destroy natural habitats, leading to biodiversity loss. They can can disrupt migration patterns and breeding grounds for many species.
Efforts to Mitigate the Impact
Given these significant dangers, there are creative efforts to divert waste from landfills through recycling, composting, and reuse:
Recycling reduces the volume of waste in landfills and conserves natural resources.
Composting organic waste turns it into valuable fertilizer, reducing waste in landfills and enriching the soil.
Reuse programs encourage using items multiple times, reducing the need for new products and waste.
Habitat for Humanity ReStores: A Model for Reuse
Since 2013, Habitat for Humanity ReStores has diverted a whopping 2.1 million tons of waste from landfills to reuse. Restores are nonprofit home improvement stores and donation centers that sell new and gently used furniture, home accessories, building materials, and appliances to the public. The first Habitat for Humanity ReStore opened in Austin, Texas, in 1992 to unused building materials from Habitat for Humanity construction sites. Since then, Habitat affiliates have opened more than 1,200 ReStores across the U.S. and Canada.
Proceeds from every item sold at ReStore support Habitat for Humanity's work to create more housing opportunities.
Utility 2030 Collaborative Service Project
On September 16, 2024, attendees of the U2030 Annual SPARK Meeting are partnering with Habitat for Humanity to assist with the reopening of a beloved ReStore in Wilson County, Tennessee. After nearly four years of closure, Habitat for Humanity is excited about reopening and reconnecting with the Wilson County community.
How You Can Help
There are several ways to help reduce waste in landfills:
Join U2030 Volunteers: Joining U2030 volunteers is as easy as RSVPing for the project when registering for the U2030 Annual SPARK Meeting.
Volunteer Locally: Habitat for Humanity of Greater Nashville ReStore in Wilson County is recruiting dedicated staff and volunteers to bolster the reopening and sustaining operations of the Wilson ReStore.
Donate Reusable Items: Donating reusable items to a ReStore location near you can make a significant difference.
Practice Recycling and Composting: Implement composting practices in your daily life and improve your recycling efforts to reduce the amount of waste going to landfills.
Spread Awareness: Educate others about the dangers of landfills, the importance of sustainable waste management practices, and opportunities to donate to a local ReStore location.
Conclusion
The average American produces nearly five pounds of trash daily, while a family generates about 18 pounds, amounting to 1,642 pounds per person and 6,570 pounds per family annually. While landfills should manage our waste safely, they often pose significant risks to water, air, soil, and wildlife.
To mitigate the impacts of our trash, we must rethink our approach to waste and explore creative alternatives beyond disposal. Reusing items through donations to Habitat for Humanity ReStores offers a powerful alternative. As the adage goes, “One person’s trash is another person’s treasure.”
