Why You Need a Compost Accelerator?

A compost accelerator, as the name suggests, is a substance that speeds up the decomposition process of organic matter. It’s like giving your compost pile a boost to help it break down materials faster and more efficiently.

You might wonder why you would need a compost accelerator when nature can take its course. Well, in an ideal world, where we all have plenty of space and time, letting nature do its work would be the best course of action. However, most of us live in urban or suburban environments where space is limited, and the composting process needs to be as efficient as possible.

Another reason you might need a compost accelerator is the type of waste you’re composting. Some materials are slower to decompose than others. For instance, leaves, twigs, and straw are high in carbon and break down slowly. On the other hand, green materials like vegetable scraps and coffee grounds are high in nitrogen and decompose quickly. A compost accelerator can help balance these elements, ensuring that your compost pile breaks down at an even rate.

Lastly, seasonal changes can also affect the composting process. In colder months, the decomposition process slows down significantly. A compost accelerator can maintain the activity in your compost pile during these colder periods, ensuring that you have a steady supply of compost throughout the year.

Benefits of DIY Compost Accelerators

Making your own compost accelerator at home comes with a number of benefits. Let’s explore some of them:


DIY compost accelerators are a cost-effective solution compared to commercial accelerators. The ingredients required are often already available in your kitchen or garden, meaning you don’t have to spend extra money.

Environmentally Friendly

By making your own compost accelerator, you’re not only speeding up the composting process but also reducing waste and minimizing the use of chemical fertilizers. It’s a win for both your garden and the environment.

Control Over Ingredients

When you make your own compost accelerator, you know exactly what goes into it. This means you can avoid any chemicals or additives that are often found in commercial products.


You can tailor your homemade compost accelerator based on the type of waste you’re composting. For instance, if you’re composting lots of dry leaves, you can add more nitrogen-rich ingredients to your accelerator.


Making your own compost accelerator can be a great educational activity. It’s a chance to learn more about the science of composting and how different materials break down over time.


There’s a unique satisfaction that comes from creating something useful with your own hands. Plus, seeing your kitchen and garden waste transform into nutrient-rich compost is incredibly rewarding.

Necessary Materials for Your DIY Compost Accelerator

Creating your own compost accelerator at home is relatively straightforward and doesn’t require a lot of materials. Here’s what you’ll need:

Organic Waste

The primary ingredient for any compost pile or accelerator is organic waste. This can be anything from kitchen scraps (fruit and vegetable peels, coffee grounds, eggshells) to yard waste (grass clippings, leaves, small branches). Try to maintain a balance between green waste (high in nitrogen) and brown waste (high in carbon).


Water is essential for the composting process as it helps to break down the organic matter. However, it’s important to find a balance – too much water can drown the microorganisms that help with decomposition.


Oxygen is crucial for the composting process. It helps the microorganisms break down the organic material. Make sure your compost pile is well aerated by turning it regularly.

A Compost Bin or Pile

Whether you choose to have a compost bin or just a pile in your backyard depends on the space available to you. A bin can be more efficient and tidy, but a pile works just as well if managed properly.

Nitrogen Source

To speed up the composting process, you’ll need a source of nitrogen. This could be green kitchen waste like vegetable peels, coffee grounds, or even some natural fertilizers like blood meal or bone meal.

Compost Starter

This is an optional ingredient, but it can help jumpstart the composting process. You can use a handful of garden soil or finished compost as a starter.

Step-by-step Guide to Making Your Own Compost Accelerator

Creating your own compost accelerator is a straightforward process that can be accomplished with minimal effort. Follow these steps:

Collect Your Materials

Start by gathering all your organic waste. Remember to maintain a good balance between green (nitrogen-rich) and brown (carbon-rich) materials.

Choose Your Compost Bin or Spot

Decide where you want your compost pile to be. If you have a compost bin, this can be anywhere in your yard. If not, choose a spot that’s out of the way but easy to access.

Start Your Compost Pile

Start your compost pile with a layer of brown materials like leaves or straw to help with aeration and drainage.

Add Your Green and Brown Materials

Add your green and brown materials in layers, starting with green materials like kitchen scraps. Follow this with a layer of brown material. Continue alternating between green and brown layers until your compost pile is about 1 meter high.

Add Water

Moisten your compost pile but be careful not to make it too wet. The compost pile should be as damp as a wrung-out sponge.

Turn Your Compost Pile

Use a garden fork or shovel to turn your compost pile every week. This helps to aerate the pile and speeds up the decomposition process.

Add Your Nitrogen Source

Sprinkle your nitrogen source over your compost pile. This could be green kitchen waste or a natural fertilizer like blood meal or bone meal.

Add Your Compost Starter

If you’re using a compost starter, add it now. This could be a handful of garden soil or finished compost.

Continue the Process

Continue adding layers of green and brown material, water, and your nitrogen source. Turn your compost pile regularly to keep it well aerated.


Now the hardest part – waiting. It can take anywhere from 2 weeks to 2 months for your compost to be ready depending on the materials you used and the conditions of your compost pile.

Tips and Tricks for a Successful Compost Accelerator

Making a DIY compost accelerator is not just about following the steps; it’s also about understanding the process and knowing how to ensure its success. Here are some tips and tricks to help you along:

Maintain the Right Balance

The ideal ratio of green to brown material in your compost pile is about 1:3. This ensures a good balance of nitrogen and carbon, which is crucial for effective composting.

Turn Your Compost Regularly

Regular turning helps aerate your compost pile and speeds up the decomposition process. Aim to turn your compost pile once a week.

Monitor Moisture Levels

Your compost pile should be as damp as a wrung-out sponge. If it’s too dry, add more water. If it’s too wet, add more brown material to absorb the excess moisture.

Cut Materials into Smaller Pieces

Smaller pieces decompose faster, so cut your kitchen scraps and yard waste into smaller pieces before adding them to your compost pile.

Avoid Adding Certain Materials

Not all organic materials are suitable for composting. Avoid adding meat, dairy, diseased plants, and pet waste as these can attract pests or create unpleasant odors.

Use Mature Compost to Speed Up the Process

Adding a layer of mature compost or garden soil to your compost pile can introduce microorganisms that speed up the decomposition process.

Be Patient

Composting is a natural process and it takes time. Don’t be discouraged if your compost pile doesn’t seem to be decomposing quickly. It will get there eventually!

Troubleshooting Common Issues with DIY Compost Accelerators
