Composting is an environmentally friendly method of recycling organic waste, reducing landfill volume, and providing nutrient-rich soil for gardening. Many people know that fruit and vegetable scraps can be composted, but what about bread? This comprehensive guide will cover the pros and cons of composting bread, reasons to compost bread, reasons not to compost bread, and additional questions related to composting bread and similar items.

Can Bread Be Composted?

Bread can indeed be composted, as it serves as a valuable carbon source for a healthy compost pile. However, it’s essential to compost bread with care to prevent potential issues like attracting pests and mold growth. By breaking bread into smaller pieces, burying it deep within the compost pile, and balancing it with nitrogen-rich materials, you can successfully incorporate bread into your composting routine and contribute to a more sustainable and eco-friendly lifestyle.

Pros of Composting Bread

Composting bread offers several advantages that contribute to a more sustainable and eco-friendly lifestyle:

  1. Reducing Waste: Bread composting helps minimize food waste, a major contributor to greenhouse gas emissions. By composting bread, you transform waste into a valuable resource for your garden.
  2. Nutrient-Rich Compost: Bread is abundant in carbohydrates, which decompose into carbon, a vital element for a healthy compost pile. This carbon source balances the nitrogen content from other compost materials, promoting decomposition and the production of nutrient-rich compost.

Cons of Composting Bread

Despite its benefits, composting bread has some drawbacks that may discourage certain individuals:

  1. Attracting Pests: Bread can entice unwanted pests such as rodents and insects to your compost pile due to its aroma and nutritional value. This can disrupt the composting process and pose potential health risks.
  2. Mold Growth: Bread is susceptible to mold growth, potentially introducing unwanted mold spores to your compost pile. Some molds can be detrimental to plants or even human health.

Tips for Composting Bread Correctly

  1. Bury the Bread: To avoid attracting pests, bury bread deep within your compost pile. This will make it more difficult for rodents and insects to locate the bread, and the heat generated by the decomposition process will help break it down more quickly.
  2. Break It Up: Tear or crumble the bread into smaller pieces to speed up the decomposition process. Smaller pieces have more surface area, making it easier for microbes to break them down.
  3. Balance Your Compost: Ensure your compost pile has a proper balance of carbon and nitrogen materials. Bread, as mentioned earlier, is a carbon source. Balance it with nitrogen-rich materials like fruit and vegetable scraps, grass clippings, or coffee grounds to maintain a healthy compost environment.
  4. Monitor Moisture: Keep your compost pile moist but not overly wet. Excessive moisture can lead to anaerobic conditions that slow decomposition and promote the growth of harmful bacteria.
  5. Avoid Excessive Bread: While bread can be composted, it’s best to do so in moderation. A compost pile with too much bread can become unbalanced and slow down the decomposition process. Mix in other types of organic waste to maintain a diverse compost mixture.

Can You Compost Moldy or Stale Bread?

Yes, you can compost moldy or stale bread. However, take extra precautions to prevent mold spores from spreading and attracting pests. Bury moldy bread deep within your compost pile to minimize exposure to other materials and reduce the risk of pest infestation.

Is Bread Brown or Green Compost?

Bread is considered a brown compost material due to its high carbon content. Brown compost materials help balance the nitrogen-rich green compost materials, such as fruit and vegetable scraps, ensuring a healthy compost pile.

Can You Compost Things Similar to Bread?

Yes, you can compost items similar to bread, such as:

  1. Cereal: As a grain-based product, cereal can be composted. Ensure it is free of excess sugar or artificial additives before composting.
  2. Pasta: Plain, cooked pasta can be composted, but avoid adding pasta with sauce, oils, or heavy seasonings.
  3. Rice: Cooked rice can be composted, but avoid adding large amounts to prevent clumping and slow decomposition.
  4. Crackers: Plain, unsalted crackers can be composted, but minimize the addition of salty or heavily seasoned products.


While composting bread is possible, it requires extra care to avoid potential issues like pests and mold. By considering the benefits and drawbacks, you can make an informed decision about whether composting bread is right for you. Following the tips provided and incorporating similar items in moderation can help you maintain a healthy, diverse compost pile and contribute to a sustainable, eco-friendly lifestyle.

FAQ about composting bread

Is burnt bread good for compost?

Burnt bread can be composted, but its high carbon content and potential for introducing contaminants make it advisable to use in moderation and mix it with other organic materials.

Can worms eat bread in compost?

Yes, worms can eat bread in compost, but it should be provided in small amounts to avoid attracting pests and to maintain a balanced diet for the worms.

Is pizza compostable?

Pizza can be compostable, but it is best to remove toppings like meat and cheese, as they can attract pests and cause unpleasant odors. Compost only the plain crust and ensure it is mixed with other organic materials.
