Benefits of Composting
Composting in Boulder, CO, offers a multitude of environmental benefits. First and foremost, composting contributes significantly to soil health. By adding compost, one enhances the soil structure, which in turn improves its ability to retain nutrients and water. This leads to healthier soils that require less water, benefiting plants and reducing water bills.
Moreover, composting helps to reduce waste going into landfills. Organic materials in landfills decompose anaerobically, releasing methane emissions, a potent greenhouse gas. Through composting, these emissions are significantly minimized as organic waste breaks down aerobically.
Below is a brief list of composting benefits:
Soil Amendment: Compost adds valuable nutrients back to the soil, promoting plant growth and health.
Waste Reduction: Keeps organic materials out of landfills, thus cutting down the volume of waste.
Water Conservation: Compost-amended soil retains moisture more effectively, requiring less irrigation.
Climate Change Mitigation: Absorbs and stores carbon dioxide, reducing the overall carbon footprint.
The practice of composting aligns with Boulder County's commitment to sustainability and environmental stewardship. Residents are encouraged to adopt composting to not only enrich their gardens but also to participate in an effort that curbs greenhouse gas emissions and nurtures healthy soils capable of sequestering carbon dioxide – a critical step in the battle against climate change.
Basic Composting Principles
Composting in Boulder, CO, centers on a balance of carbon-rich materials, known as 'browns', and nitrogen-rich materials, or 'greens'. Browns are typically dry and add bulk, including items such as leaves, straw, and paper. Greens are usually wet and include materials such as food scraps and lawn clippings.
A successful compost pile should have:
A ratio of about 3 parts brown to 1 part green material
Sufficient moisture to keep the pile damp
Adequate oxygen, which is introduced through turning the pile
A sizeable heap to generate enough heat for decomposition
Do's Don'ts Mix in fruit and vegetable scraps Add meat or dairy products Include grass clippings and plant trimmings Use treated wood or coal ash Turn the pile regularly for aeration Let the compost dry out completely
Moisture and oxygen are crucial for the microorganisms that break down the organic matter. The pile should be as damp as a wrung-out sponge and turned at least once a week to provide oxygen and distribute heat more evenly.
Compost provides a wealth of benefits. It enriches the soil, helping retain moisture and suppress plant diseases and pests. It also encourages the production of beneficial bacteria and fungi that break down organic matter to create humus, a rich nutrient-filled material.

Setting Up a Composting System
Setting up a composting system in Boulder requires choosing an appropriate method, gathering necessary materials, and properly placing and managing your compost bin.
Choosing a Composting Method
When deciding on a composting method, Boulder residents may consider both backyard composting and community composting options. Backyard composting is a personal approach, allowing for close monitoring and control. Alternatively, participating in community programs can alleviate the labor of maintaining a compost system, with organizations like A1 Organics managing compostable waste.
Materials Needed for Composting
To start composting, one needs a balance of greens, such as fruit and vegetable scraps, and browns, like dried leaves and paper. A compost bin or pile should be set up to contain the materials. Home composters can opt for commercially available bins or create their own from materials like wood or repurposed trash bags. It's essential to use only compostable products to reduce contamination in the compost.
Compost Bin Placement and Management
The placement of a compost bin is crucial; it should be situated in a convenient but unobtrusive site with good drainage and partial sunlight. For effective management, the compost should be turned regularly to aerate the pile and speed up the decomposition process. One should monitor the balance of materials, adding more browns or greens as necessary to maintain a proper carbon to nitrogen ratio.
What to Compost
Proper composting in Boulder requires understanding what materials should be included. The goal is to create a balanced mix of green and brown materials that enhances decomposition, while avoiding items that could cause issues with the composting process.
Green Materials
Green materials are rich in nitrogen and necessary for the composting process:
Food Scraps: Most leftovers, including fruits, vegetables, coffee grounds, and eggshells, can be composted.
Grass and Yard Trimmings: Freshly cut grass and green leaves provide excellent nitrogen sources.
Remember to include items such as bones, meat, and dairy products, which are accepted in the Boulder composting program.
Brown Materials
Brown materials provide carbon, which is equally important:
Leaves: Fallen leaves, when dried, are a staple in the brown material category.
Yard Trimmings: Items such as dry twigs and branches contribute to the carbon balance.
Adequate layering of these materials will facilitate the composting process.
Items to Exclude
Certain materials should not be composted because they can attract pests, cause odors, or contain harmful substances:
