Organic Materials

Composting is a great way to reduce waste and enrich your soil at the same time. But not all organic materials break down at the same rate. Some decompose rapidly, while others take longer to transform into nutrient-rich compost. In this article, we’ll explore which materials turn into compost the fastest and how you can utilize them effectively in your composting efforts.

Fruits and Vegetables

Fruits and vegetables are among the quickest organic materials to decompose in a compost pile. Due to their high water content and relatively soft structure, they break down rapidly and release essential nutrients into the soil. It’s important to chop them into smaller pieces before adding them to the compost bin, as this speeds up the decomposition process even further. So, don’t hesitate to toss those carrot peels, apple cores, and wilted lettuce leaves into your compost pile!

Coffee Grounds

Coffee lovers rejoice! Coffee grounds are not only a great addition to your morning routine, but they are also an excellent source of nitrogen for composting. Thanks to their fine texture and high nitrogen content, coffee grounds break down quickly, helping to accelerate the decomposition of other materials in your compost pile. Make sure to spread them evenly throughout the pile to ensure a balanced breakdown of organic matter.


Don’t throw away those eggshells after making breakfast! Eggshells contain calcium, which is crucial for healthy soil and can aid in the decomposition process. While eggshells take a bit longer to break down compared to fruits and vegetables, they provide an essential element to your compost. Crushed eggshells also help deter pests like slugs and snails due to their sharp edges, making them an excellent addition to your compost bin.

Grass Clippings

If you mow your lawn regularly, you already have a fast composting material readily available – grass clippings. Grass clippings are high in nitrogen and moisture, making them ideal for speeding up the decomposition process. However, it’s essential to use them in moderation and mix them well with other organic materials to prevent clumping and promote airflow within the compost pile. A thin layer of grass clippings mixed with dry leaves or shredded paper can work wonders for your composting efforts.

Plant Trimmings

When it comes to plant trimmings, such as leaves, pruned branches, and flower trimmings, their decomposition rate can vary. However, they generally break down relatively quickly and provide a range of nutrients to your compost. Leaves are particularly beneficial as they contain a high carbon-to-nitrogen ratio, which helps balance out the compost pile. Chopping pruned branches into smaller pieces and crushing flower trimmings can help speed up their decomposition process.

Animal Matter

Animal matter, such as manure, feathers, hair, and fur, can also contribute to the composting process. Manure, especially from herbivorous animals like cows or horses, is rich in nitrogen and accelerates decomposition. Feathers, hair, and fur, on the other hand, are high in carbon and help maintain a balanced carbon-to-nitrogen ratio in your compost. While these materials may take longer to decompose compared to fruits and vegetables, they are valuable additions to create nutrient-rich compost.

Paper Products

Newspaper, cardboard, and shredded paper can be excellent sources of carbon for your compost pile. Although they may take a bit longer to break down than other materials, they add structure to the compost and help maintain moisture levels. Newspaper and cardboard should be shredded or torn into smaller pieces to facilitate faster decomposition. Avoid using glossy or colored paper, as it may contain chemicals that are not beneficial to the composting process.


Wood-Based Materials

Sawdust and wood chips are considered “brown” or carbon-rich materials, necessary to balance the nitrogen-rich “green” materials in your compost. While they take longer to decompose, they provide essential aeration and help prevent the compost from becoming too compact. It’s important to mix sawdust and wood chips well with other organic materials and monitor the moisture levels to ensure proper decomposition.

Kitchen Scraps

Many kitchen scraps can be composted quickly, contributing to the overall richness of your compost. Tea bags, including the contents, are great additions as they decompose rapidly and provide nitrogen. Crushed nutshells, such as those from peanuts or almonds, are also suitable due to their carbon content. Tofu, being a food source made primarily from soybeans, adds both nitrogen and moisture to the compost pile. Just be sure to cut tofu into smaller pieces to promote faster decomposition.


Garden Waste

Garden waste, such as weeds, straw, and hay, can be easily included in your compost cycle. Weeds, although they should be avoided if they’ve gone to seed, break down quickly and provide nutrients to the compost. Straw and hay, being carbon-rich materials, lend structure to the compost pile and help retain moisture. By mixing these garden waste materials with other organic matter, you can expedite decomposition and turn them into valuable compost.

What Turns Into Compost Fastest:  Miscellaneous

In addition to the aforementioned categories, there are several other organic materials that can be composted relatively quickly. Dry leaves, often abundant during autumn, add carbon and help balance the composting process. Cotton and linen products, such as old clothing or towels, break down at a moderate pace and contribute valuable carbon. Seaweed, a renewable and nutrient-rich resource, is an excellent composting material due to its high mineral content.

The Art of Balancing a Compost Pile

An effective compost pile is much like a gourmet recipe; it requires a balance of ingredients to produce the desired outcome. What turns into compost fastest is influenced by the ratio of green to brown materials, which provides the necessary nitrogen and carbon. Greens are typically wet and rich in nitrogen, such as kitchen scraps and fresh plant matter. Browns are dry and carbonaceous, like leaves, straw, and paper. The ideal pile should have more browns than greens, aiming for a carbon-to-nitrogen ratio of about 30:1.

Microbial Activity: The Engine of Composting

Microorganisms are the true heroes of composting. They break down organic matter into humus, a complex organic substance resulting from the decomposition. The faster these microorganisms work, the quicker you get compost. To thrive, they need the right conditions: moisture, oxygen, and a balanced diet of nitrogen and carbon. Turning the pile regularly introduces oxygen and keeps the microorganisms happy and active.

The Role of Temperature in Composting

Heat is a byproduct of microbial metabolism. The temperature of your compost pile is a good indicator of microbial activity. A hot pile is a busy pile. Composting happens fastest between 135-160°F (57-71°C). At these temperatures, most weed seeds and pathogens are killed, and organic matter breaks down quickly. Monitoring the temperature helps in managing what turns into compost fastest.

Composting in Different Climates

The rate of composting can vary greatly depending on the climate. In warmer regions, compost piles break down faster due to the higher temperatures stimulating microbial activity. In colder climates, composting can be a slower process, but it can be accelerated by placing the pile in a sunny location, using a compost bin to retain heat, or even insulating the pile with a layer of browns.

Speeding Up Composting with Additives

Commercial compost accelerators can be added to a compost pile to speed up the process. These additives often contain microorganisms and enzymes that kick-start the decomposition. However, a well-managed compost pile typically doesn’t need these additives, as it naturally contains all the necessary microorganisms for decomposition.

The Impact of Compost Size and Shape

The size and shape of your compost pile can affect how quickly it turns into compost. A pile that is too small may not retain enough heat, while a pile that is too large may not get enough oxygen to its center. A pile that is about 3 feet high and wide is often considered ideal for balancing these factors.

Using Compost Tumblers for Faster Results

Compost tumblers are a modern solution to traditional composting methods. These enclosed containers are designed for easy turning, which aerates the pile and speeds up the composting process. They can be particularly useful for urban gardeners who have less space but still want to benefit from what turns into compost fastest.

The Benefits of Composting for Soil Health

Compost is not just a waste disposal system; it is a vital supplement for soil health. It improves soil structure, water retention, and provides a slow-release of nutrients. By understanding what turns into compost fastest, you can regularly contribute to the soil’s health, leading to more robust plant growth and better yields.

Avoiding Common Composting Mistakes

To ensure that you’re composting as efficiently as possible, avoid common pitfalls. Don’t let the pile dry out, or it will slow down the process. Avoid adding meat, dairy, or oily foods that can cause odor problems and attract pests. And ensure that your pile has sufficient browns to avoid becoming a slimy, anaerobic mess.

Composting Indoors with Bokashi

For those with limited outdoor space, Bokashi composting is an anaerobic process that can be done indoors. Bokashi bran, impregnated with beneficial microorganisms, ferments kitchen waste, including meats and dairy, into a form that can be buried in soil or added to a compost pile to finish decomposing.

Vermicomposting: Worms Doing the Work

Vermicomposting is another indoor composting option where red wigglers turn organic waste into compost quickly. The worms’ digestive process breaks down the food waste efficiently, producing worm castings, a nutrient-rich form of compost.

Community Composting: A Collective Effort

Community composting programs allow individuals who don’t have the space or resources to compost on their own to contribute their organic waste to a communal pile. These programs can handle larger volumes of waste and often have systems in place to optimize what turns into compost fastest.

Teaching Children About Composting

Including children in the composting process can be an educational experience. It teaches them about the life cycle of organic matter and the importance of sustainability. By engaging in composting, children learn what turns into compost fastest and see firsthand the benefits of their efforts on garden plants.

The Future of Composting Technology

Innovations in composting technology continue to emerge, from smart compost bins that monitor moisture and temperature to industrial-scale composters that can handle the organic waste of entire communities. These advancements promise to make composting more efficient and accessible for everyone.
