Composting Noodles: A Complete Guide

Composting food scraps like noodles can reduce waste and create nutrient-rich soil for gardening. But can noodles really be composted? What types of noodles work best? And are there any precautions to take? This guide covers everything you need to know about composting noodles.

Can You Compost Noodles?

The short answer is yes, you can compost most types of uncooked noodles without issue. Noodles are made from wheat or rice flour, both of which break down readily in a compost pile or bin.

Cooked noodles tend to be more attractive to pests than uncooked noodles. The moisture and starch make them a tasty snack for small animals like rats or raccoons. But as long as you only add uncooked noodles, this shouldn't be a problem.

So feel free to toss any leftover dried noodles into your compost. They provide a good source of carbon that helps balance the nitrogen from fruit and vegetable scraps.

Best Noodles for Composting

You'll have the most success composting basic noodles made from wheat flour, rice flour, buckwheat flour or bean flour. Varieties like spaghetti, linguine, egg noodles, soba noodles, udon noodles and rice noodles all compost well.

Avoid noodles with added oils, flavors or extensively processed wheat flour, as these take longer to break down. Lasagna noodles, ramen noodles and flavored instant noodles fall into this category.

And steer clear of noodles made from corn. Corn breaks down very slowly in compost.

How to Prepare and Add Noodles to Your Compost

To add noodles to your compost:

  • Break long noodles into smaller pieces. This increases the surface area for microbes and decomposition.

  • Make sure noodles are uncooked and dried out. Don't add clumped or cooked noodles as these can turn moldy.

  • Mix noodles into the center of the pile. This prevents animals from pulling them out.

  • Bury noodles under 10 inches of compost. This also deters pests.

  • Add equal parts brown and green materials like leaves, grass clippings or vegetable scraps to balance the carbon and nitrogen.

  • Turn or stir the compost pile weekly to aerate it. This speeds up decomposition.

  • Make sure the compost maintains a moisture level of 40-60%. Add water if it becomes too dry.

How Long Does it Take for Noodles to Decompose?

On average, uncooked noodles take 1 to 2 years to break down completely in a compost pile. Exact timing depends on factors like:

  • Noodle ingredients - Rice noodles decompose faster than wheat-based noodles. Egg noodles take longer to break down than plain varieties.

  • Particle size - Smaller noodle pieces compost quicker than longer noodles.

  • Aeration - Turning the compost provides oxygen to help decomposition.

  • Moisture - Noodles need moisture to break down.

  • Temperature - Compost with a consistent internal temperature between 90-140°F decomposes fastest.

So with proper conditions, those leftover noodles can decompose in around 1 to 2 years. They'll provide carbon, starch and nutrients to help create rich, finished compost for your garden.

Other Foods You Can Compost

Noodles are just one of many food scraps that can be composted. Other items you can add include:

  • Fruits and vegetables
  • Eggshells
  • Coffee grounds and filters
  • Tea bags
  • Nut shells
  • Shredded newspaper
  • Cardboard
  • Dryer lint
  • Leaves and yard trimmings

Avoid meats, oils, bones, dairy and prepared foods. And moderation is key with starchy foods like noodles and rice.


Composting noodles is an easy way to reduce food waste and recycle their nutrients back into the soil. Follow these guidelines for successful composting:

  • Stick to uncooked, plain wheat or rice noodles
  • Break noodles into smaller pieces
  • Bury deep under other compost materials
  • Maintain proper aeration, moisture and temperature

In 1-2 years, you'll have rich compost to nourish your garden and houseplants. Composting noodles and other food scraps benefits the health of your plants and the planet.
