What are play area woodchips?

Play area woodchips, also known as playground wood mulch or play bark, are typically made from woody materials such as logs, tree branches, and stumps. They are commonly used as a shock-absorbing surface in children’s playgrounds to provide a softer landing and reduce the risk of injuries. Play area woodchips are available in various sizes and can be a natural alternative to synthetic materials like rubber or asphalt.

Benefits of using woodchips in play areas

Using woodchips in play areas offers several benefits. Firstly, they provide a soft and cushioned surface that helps prevent injuries from falls. Compared to harder surfaces like concrete or asphalt, woodchips have shock-absorbing properties that can greatly reduce the impact of a fall. Additionally, woodchips can help in moisture retention, keeping the play area relatively dry and reducing the risk of slips and falls.

Furthermore, woodchips are a sustainable and eco-friendly option for play areas. They are made from natural materials, which means they are biodegradable and can break down over time without causing harm to the environment. Woodchips also have a natural appearance that blends well with outdoor surroundings, giving the play area a more serene and aesthetically pleasing look.

Composting process

What is composting?

Composting is the natural process of decomposition, where organic materials break down into a nutrient-rich material called compost. It involves the breakdown of organic matter, such as food scraps, yard waste, and woodchips, by microorganisms like bacteria, fungi, and worms. During this process, the organic matter goes through various stages and transforms into a dark, crumbly substance that is beneficial for plants and soil health.

How does composting work?

Composting works by providing the right conditions for microorganisms to thrive and break down organic matter. Microorganisms require four main components to carry out the composting process: carbon, nitrogen, oxygen, and water. Carbon-rich materials, such as woodchips, provide energy for microorganisms, while nitrogen-rich materials, like food scraps or grass clippings, supply proteins for growth.

The composting process is driven by the microorganisms’ metabolic activities, which generate heat. This heat helps break down the organic matter faster, resulting in a more efficient decomposition process. As the organic matter decomposes, it releases nutrients and forms humus, a stable material that improves soil structure and fertility.

Requirements for successful composting

To achieve successful composting, certain conditions need to be met. First, a proper balance of carbon and nitrogen is crucial. The ideal carbon to nitrogen ratio, known as the C:N ratio, is approximately 30:1. Woodchips are high in carbon, so they should be combined with nitrogen-rich materials, such as grass clippings or kitchen scraps, to achieve a balanced C:N ratio.

Additionally, composting requires sufficient oxygen and moisture. Oxygen is necessary for the microorganisms to carry out aerobic decomposition. This can be achieved by turning the compost pile regularly to introduce air or using a compost bin with built-in aeration. Moisture levels should be maintained between 40-60%, similar to a damp sponge, to support the microorganisms’ activity without becoming too wet or dry.

Can play area woodchips be composted?

Yes, play area woodchips can be composted! Since woodchips are organic materials, they can break down and contribute to the composting process. However, it’s important to consider a few factors before composting play area woodchips to ensure successful decomposition and a high-quality finished compost.

Factors to consider when composting play area woodchips

Type of woodchips

The type of wood used in the play area woodchips can affect the composting process. Hardwoods decompose slowly due to their dense nature. Softwoods break down quicker. It’s important to be aware of the wood type and adjust the composting process accordingly.

Contamination levels

It is essential to inspect the woodchips and remove any foreign objects before composting. These contaminants can hinder the composting process or end up in the finished compost, which may be detrimental to plants or gardens.

Moisture content

The moisture content of the woodchips is crucial for successful composting. Woodchips tend to be dry, so adding water during the composting process may be necessary to maintain the ideal moisture levels. It’s important to prevent the woodchips from becoming too dry or too wet, as this can affect the microbial activity required for decomposition.

Carbon-nitrogen ratio

As mentioned earlier, achieving the right carbon-nitrogen ratio is important for effective composting. Since woodchips are carbon-rich, they should be mixed with nitrogen-rich materials, such as grass clippings or vegetable scraps, to achieve a balanced C:N ratio.

Composting time

Woodchips typically require a longer time to decompose compared to other organic materials. Patience is key when composting play area woodchips, as the process may take several months to years, depending on the conditions and size of the woodchips.

Advantages and disadvantages of composting play area woodchips


Composting play area woodchips offers several advantages. Firstly, it helps divert waste from landfills, promoting a more sustainable approach to waste management. Composting woodchips also creates a valuable soil amendment that can be used to improve soil structure, retain moisture, and provide nutrients for plants.

Secondly, composting play area woodchips reduces the need for synthetic fertilisers or chemical additives in gardening or landscaping. Nutrient-rich compost from the woodchips can naturally nourish plants, promote healthier growth, and enhance overall soil health.

Lastly, composting play area woodchips contributes to the circular economy by closing the loop of organic materials. By composting the woodchips, you are completing the cycle and returning them to the earth, where they can be beneficial once again.


While the advantages of composting play area woodchips are numerous, there are a few potential disadvantages to consider. Firstly, as mentioned earlier, woodchips take longer to decompose compared to some other organic materials. This means that the composting process may require more time and patience.

Different methods of composting play area woodchips

Traditional composting

Traditional composting involves creating a compost pile or bin where organic materials, including play area woodchips, are layered and left to decompose naturally over time. The pile needs to be regularly turned to provide oxygen and ensure even decomposition. This method typically takes several months to a year to produce finished compost.


Vermicomposting is a method of composting that utilises worms, typically red wigglers, to help break down organic materials. Play area woodchips can be added to a vermicomposting bin, along with kitchen scraps, and the worms will consume the organic matter, digest it, and produce nutrient-rich worm castings. Vermicomposting is a faster process compared to traditional composting and can produce finished compost in a matter of weeks or months.

Thermophilic composting

Thermophilic composting relies on heat-loving microorganisms to break down organic materials quickly. The process involves creating a compost pile that reaches high temperatures, ranging from 120°F to 160°F (49°C to 71°C). These elevated temperatures accelerate decomposition and kill pathogens and weed seeds. Play area woodchips can be added to a thermophilic compost pile to aid in the breakdown process and produce rich compost within a few months.

Step-by-step guide to composting play area woodchips

Prepare the woodchips

Inspect the play area woodchips for contaminants and remove them. If the woodchips are excessively dry, moisten them with water until they reach the ideal moisture level, similar to a damp sponge.

Build a compost pile

Choose a suitable location for your compost pile or obtain a compost bin. Use a layering technique to build the pile, alternating between woodchips and nitrogen-rich materials like grass clippings or vegetable scraps. Aim for a balanced carbon-nitrogen ratio of approximately 30:1.

Monitor and maintain the compost pile

Regularly monitor the moisture levels of the compost pile and adjust as needed. The compost pile should feel moist, but not soggy. Turn the pile every few weeks using a garden fork or shovel to introduce oxygen and ensure even decomposition. This helps speed up the composting process.

Turn and aerate the compost

To maintain optimal decomposition rates, continue turning the compost pile every few weeks. This ensures that all the organic materials, including the woodchips, are evenly exposed to oxygen. Aerate the pile by poking holes in it with a garden fork to improve airflow.

Harvest and use the finished compost

Once the woodchips and other organic materials have fully decomposed into a dark, crumbly substance, the compost is ready to be harvested. Use a garden rake or shovel to scoop out the finished compost and use it to enrich your garden soil or as mulch for your plants. The compost can be spread around plants or incorporated into the soil to improve fertility and water retention.


Composting play area woodchips is a sustainable and beneficial way to repurpose the material once it is no longer needed in a play area. By understanding the composting process, considering important factors, and utilising appropriate composting methods, you can successfully turn the woodchips into nutrient-rich compost that improves soil health and promotes sustainable gardening and landscaping practices.
