I happened upon this really interesting infographic the other day and was shocked to see where Colorado landed:
As modern consumers, we often discard items without much thought, trusting that our waste magically disappears once it leaves our front doors. However, the reality is that most of this waste ends up in landfills, which play a crucial role in waste management. It’s essential to understand how landfills work and why keeping them as empty as possible is vital for both environmental and human health.
How Do Landfills Work?
1. Location and Design:
Landfills are specially designed sites used for waste disposal by burial. They are strategically located away from population centers to minimize human impact. A landfill's design includes multiple layers to prevent environmental contamination, such as a liner at the bottom to prevent leachate (a liquid that drains from the landfill) from seeping into the groundwater.
2. Waste Layers:
Once waste is delivered to a landfill, it is compacted to reduce volume and then covered with a layer of soil. This layering process helps manage odors, deter pests, and control the release of debris into the environment.
3. Decomposition:
Waste in landfills decomposes anaerobically (without oxygen), producing methane—a potent greenhouse gas. Modern landfills capture this gas to minimize emissions and can convert it into energy through a process known as landfill gas recovery.
4. Monitoring and Maintenance:
Landfills are heavily monitored to ensure they don’t negatively impact the surrounding environment. This includes checking for soil contamination, groundwater pollution, and gas emissions. Regular maintenance ensures the integrity of the barriers and systems that contain the waste.
Why It’s Important to Reduce Landfill Waste
1. Environmental Impact:
Landfills are a significant source of methane, contributing to climate change. The more waste we send to landfills, the more methane is produced, potentially exacerbating atmospheric changes. Additionally, many items that we toss out take hundreds if not thousands of years to 'decompose.'
2. Finite Space:
Landfills are not infinite. As they fill up, finding new locations becomes increasingly difficult and contentious, often meeting resistance from nearby communities. Reducing waste helps maximize existing landfill space, delaying the need for new sites.
3. Pollution Risks:
Despite protections in place, landfills pose a risk of pollution to nearby soil and water bodies. Leachate can contaminate groundwater if not properly managed, posing hazards to human and environmental health.
4. Resource Conservation:
Much of the waste in landfills could have been recycled or composted. According to the EPA, around 28% of waste that goes to landfills in the US could be composted, primarily consisting of food scraps and yard waste; however, with proper diversion programs, this amount could potentially be much higher, reaching up to 34% of total municipal solid waste. By filling landfills with recyclable materials, we miss the opportunity to conserve natural resources and reduce energy consumption needed to produce new goods.
How We Can Help Keep Landfills Empty
1. Reduce, Reuse, Recycle:
The classic mantra still holds true. Reducing consumption, reusing items, and recycling materials keeps them out of landfills and in the production cycle longer. As I personally believe that not much in the way of plastics get recycled, one of the ways Refillary helps keep plastics out of the landfill is to help everyone reuse/refill them!
Reduce: Be mindful of purchases, avoiding unnecessary items with excessive packaging.
Reuse: Repurpose containers (come and refill them!!), donate clothing, or participate in community swap events.
Recycle: Follow your local recycling guidelines to ensure proper separation and disposal.
2. Composting:
Composting organic waste such as food scraps and yard waste minimizes landfill contributions and creates nutrient-rich soil. Many communities offer composting programs, and home compost bins are simple to set up. Refillary is also a compost drop off site for Compost Colorado -- sign up today!
3. Embrace Minimalism:
Adopting a minimalist lifestyle encourages mindful consumption and emphasizes quality over quantity, leading to less waste and a smaller environmental footprint.
4. Support Refill and Zero-Waste Stores:
Patronize shops like Refillary, which provide eco-friendly, packaging-free products. By refilling everyday essentials, you contribute to minimizing the waste stream heading to landfills.
5. Advocate and Educate:
Promote waste reduction and sustainability initiatives in your community. Educating others about the importance of reducing landfill waste can create ripples of positive change.
Understanding how landfills work highlights the importance of reducing the waste we send their way. By adopting sustainable habits and encouraging others to do the same, we can collectively decrease environmental impacts, preserve vital resources, and build a healthier planet for future generations.
Each small effort contributes to a larger movement toward sustainability. Let’s make conscious choices today—because a cleaner, greener tomorrow depends on it.
