Compost creates a rich source of nutrients for your garden. It also takes food scraps out of the garbage and, ultimately, the landfill, where it would release harmful methane that causes climate change. Your compost pile needs to have a good balance of food scraps with carbon-rich items like “browns” (carbon-rich materials like dried leaves) and “greens” (nitrogen-rich materials like grass clippings). Aim for a 2:1 or 3:1 ratio of browns to greens to optimize decomposition and prevent odors. This helps maintain proper aeration and moisture levels.

Here's a more detailed breakdown of why this is important and other helpful tips:

Why Balance is Key

Carbon and Nitrogen: Microorganisms that break down organic matter need both carbon and nitrogen to thrive.

Decomposition: Too much carbon (browns) can slow down decomposition, while too much nitrogen (greens) can lead to unpleasant odors and a slimy pile.

Optimizing the Process: A balanced mix ensures a faster, more efficient composting process, resulting in rich, usable compost.

Moisture: Compost needs moisture, but not too much. Aim for consistency like a wrung-out sponge.

Aeration: Regularly turn the pile to allow oxygen to reach the microorganisms.

Observation: Monitor your pile for signs of problems (smells, slow decomposition) and adjust your mix accordingly.

Don'ts: Avoid adding meat, dairy, or oily foods, which can attract pests and create odors.

Location: A compost pile can be in the sun or shade, but the sun can help speed up the process.

According to the EPA, approximately 1/4 of collected trash contains food scraps that can be composted! Composting also helps the city save money. Removing food scraps from trash reduces disposal fees charged at the landfill. The cost for organic disposal is approximately 1/3 less than the landfill rate.

If you'd like to join the College Park Curbside Food Scrap Collection Program, you can apply on the City's website, HERE. Your food scraps will be picked up every Tuesday and taken to the Prince George’s County Organics Facility for composting.
