Composting Basics
Understanding composting fundamentals allows Baltimore residents to contribute to waste reduction and environmental improvement effectively.
What Is Composting?
Composting is the process of natural decomposition of organic material, such as food scraps and yard trimmings, into a rich soil additive known as compost. By facilitating the breakdown of this organic matter, typically through the combined action of microorganisms, air, and moisture, one creates a beneficial product from materials that would otherwise occupy space in landfills.
Benefits of Composting
Reducing Waste: Composting diverts organic waste from landfills where it would take up space and potentially release methane, a potent greenhouse gas. By transforming kitchen scraps and yard debris into compost, it significantly lessens the volume of waste sent to landfills.
Improving Soil Health: Compost enriches the soil with nutrients, promoting healthier plant growth and restoring vitality to nutrient-depleted soil.
Key Components of Compost
Browns: This includes materials such as dried leaves, branches, and twigs, which add carbon to your compost.
Greens: Kitchen scraps like fruit and vegetable waste, coffee grounds, and grass clippings provide nitrogen.
Water: Maintaining the right moisture level is crucial for the composting process, as it supports the microorganisms that break down the material.
Air: Regularly turning the compost pile introduces oxygen, which is necessary for aerobic decomposition and reduces odors.
Setting Up A Compost System
Setting up a compost system at home involves selecting an optimal site, choosing the right bin, and balancing organic materials, such as yard waste and kitchen scraps. Proper setup is crucial for efficient decomposition and nutrient-rich compost.
Choosing the Right Site
When selecting a site for a compost bin, one should look for a flat, well-drained area that has good access to water. It should be partly shaded to help maintain moisture, yet receive some sun to aid in the decomposition process. The site should be convenient to the kitchen and garden but located away from neighbors to avoid any potential for odor complaints.
Types of Compost Bins
There is a variety of compost bins to suit different needs and preferences. Enclosed bins are ideal for deterring pests and retaining moisture, while open bins allow for more aeration. Individuals can Choose Your Compost System based on the volume of waste and the level of maintenance they are willing to commit to. Options range from simple wire mesh containers to sophisticated tumblers.
Balancing Greens and Browns
A successful compost bin requires a balance between 'greens', such as kitchen scraps and grass clippings, and 'browns', such as leaves, straw, and wood chips. Greens provide nitrogen, while browns add carbon. The ideal ratio is about 1 part green to 3 parts brown. Materials should be added in alternating layers and turned with a **shovel **every few weeks to introduce oxygen, which speeds up the composting process. The compost should be kept moist but not wet to the touch.
Composting Methods
In Baltimore, residents have access to several effective composting methods suitable for personal or small-scale operations. These methods contribute to waste reduction and provide nutrient-rich soil for gardens.
Backyard Composting
Backyard composting is a practical approach for turning garden waste and kitchen scraps into compost. Homeowners can use open bins, tumblers, or simply pile up compostable material in a designated area. Key materials for this method include leaves, grass clippings, fruit and vegetable scraps, and eggshells. To maintain the compost, one should regularly turn and moisten the pile to aid decomposition.
Worm Composting
Worm composting or vermicomposting utilizes red wiggler worms to break down food waste. This method is ideal for those with limited outdoor space, as it can be done indoors using a specially designed bin. The worms consume and digest the scraps, leaving behind rich compost, also known as worm castings, that can significantly benefit garden soil.
Bokashi Fermentation
The Bokashi method involves an anaerobic process that ferments organic waste, including dairy and meat, which are typically not recommended for other composting methods. This practice requires a sealed container and a mixture of microorganisms, commonly referred to as Bokashi bran, to expedite fermentation. The resulting material can be buried in the garden to finish decomposing and enrich the soil.
Composting in Baltimore
Composting in Baltimore has gained substantial traction through various initiatives, offering residents numerous opportunities to engage in waste reduction and soil enrichment practices. City-backed programs, community-driven efforts, and dedicated local facilities collectively contribute to a greener Baltimore.
City Programs and Supports
Baltimore City runs several programs to encourage and assist residents in composting. The Baltimore Office of Sustainability is instrumental in promoting environmental stewardship by offering resources on how to compost at home effectively. Furthermore, the city has a pilot program for food scraps drop-off, enabling residents to compost organic materials that would otherwise end up in landfills like the Quarantine Road Landfill.
Local Composting Facilities
Residents can compost some of their food scraps with yard materials at local facilities. The city's support for these efforts is evident in the information provided on how to build a compost pile and what materials can be composted. Some composting facilities are situated within city limits, while others, like those in Prince George's County, may be up to 40 miles away.
Community Composting Initiatives
Community-scale composting has flourished in Baltimore, with the Baltimore Compost Collective paving the way. This youth-empowered collective not only processes food scraps from Baltimore neighborhoods but also provides youth with valuable workforce skills by engaging them in the composting process. Their activities, centered around the Filbert Street Community Garden, showcase the community's commitment to sustainable practices and urban food security.
Advancing Zero Waste Goals
Baltimore's commitment to sustainability is evident in its pursuit of zero waste goals. This focus includes the development of robust projects and strategies that aim to minimize food waste, while also engaging the youth through education and entrepreneurship programs, contributing to a greener city.
Zero Waste Strategies

Troubleshooting and Maintenance
In maintaining a healthy composting system, one may encounter issues such as unpleasant odors, improper temperature and moisture levels, and unwanted pests. Understanding how to effectively troubleshoot these issues is crucial for a successful composting experience.
Managing Compost Smell
When compost emits a strong odor, it typically indicates an imbalance. A healthy compost pile should have a pleasant, earthy smell. If the compost smells like rotten eggs, it may be too wet, leading to anaerobic conditions.. To remedy this, one should add more browns (carbon-rich materials) such as dry leaves or straw to absorb excess moisture and help aerate the pile by turning it more frequently.
Conversely, a sweet or ammonia-like smell suggests an excess of greens (nitrogen-rich materials), and the solution is to add more browns to balance the nitrogen. Regular aeration and maintaining the correct green to brown ratio (approximately 1:3) will prevent most odor problems.
Temperature and Moisture Control
Temperature is a vital sign of compost health. A compost pile should remain between 130-150°F to support the decomposition process and kill pathogens. A compost thermometer can be used to monitor this. If temperatures are too low, turning the pile to introduce oxygen and adding greens can reactivate the composting process.
Moisture levels also significantly affect composting. The pile should feel like a wrung-out sponge, an indicator of ideal moisture. If it's too dry, decomposition slows, and microorganisms can't thrive, so adding water gradually while turning the compost can help. If it's too moist, increase aeration and add browns to absorb the excess moisture.
Pest Deterrence
A well-managed compost pile should not attract pests. To prevent attracting rodents and insects, one should never include meat, bones, dairy, or oils in compost. An enclosed bin or a layer of browns on top of the compost can deter pests. Regular turning of the pile and maintaining a balance of materials will also discourage pests by not allowing any one area to become overly moist or nutrient-rich, which pests find attractive.
Environmental Impact
Composting in Baltimore demonstrates a significant step towards environmental sustainability by converting organic waste into a valuable resource. This process positively impacts soil health, climate change mitigation, and fosters sustainable community practices.
Compost and Soil Health
