10 BEST Uses For Sawdust From Chainsaws And Milling

| |

What are the best uses for sawdust?

We end up with a ton of it. While I usually leave it behind in the forest or down in the gully (where I get a lot of my firewood), sometimes it’s at my front door.

I recently dragged up about 7 large logs from out of the gully to be cut up outside the house and then split. As usual, there was a lot of sawdust to deal with before it killed the grass.

Here are 10 of the best uses for sawdust if you have plenty of it lying around like us!

What To Do With Sawdust

best uses for sawdust

What can you do with sawdust?

One of the things to think about before using sawdust is the oil content.

We all use chain and bar oil in our chainsaws and this is distributed through the sawdust. If you are not using an alternative bar and chain oil like vegetable oil then a lot of people say it’s no good for anything.

For the most part, I agree, but a little bit here and there has its uses. That’s for you to decide.

If you decide you’d like some sawdust projects, here are some of the things you can do!

Let The Kids Play With It

what to do with sawdust

This is the first thing that happens with sawdust around our home, and one of the most fun uses for sawdust.

The kids love playing with it, making it into mountains, putting it into a stew or potion, and otherwise making a mess with it. I have found that sawdust attracts kids as much as water and mud, as much as I try to keep them out of it sometimes.

Especially when your chainsaw chain is nice and sharp, it makes long lengths of sawdust, as in the picture above. This has less of a tendency to be an irritant so it is great to play with!

Compost

what can you do with sawdust

Adding sawdust to your compost, as I have done here, is another good use for it.

I never put too much in because of the oil content and because it can decrease nitrogen levels in the soil. However, I also add horse manure and chicken poo to the compost so that helps combat any problems there.

My compost is also full of waste like lawn clippings and vegetable greens (broccoli plants, for example) which also help to increase nitrogen levels. Sawdust is just another ingredient that enriches your compost when used in the right amounts.

Straight Into The Soil

can you add sawdust to the garden soil

In some parts of the garden, it might make sense to add sawdust right into the soil.

In the greenhouse pictured above, my nitrogen levels were too high. So much so, that the summer before this picture was taken, my usually fruitful grapevine produced beautiful glorious leaves everywhere but had no fruit.

I suspect this was because I added too much chicken poo to the soil the previous winter and spring. I’ve read that soil with high nitrogen content can cause this to happen. Adding a bit of sawdust will hopefully level things out a bit and earn me some grapes next summer!

As far as food goes, mushrooms can also be grown in sawdust. Shiitake mushrooms, for example, like to be in a mix of 95% hardwood sawdust.

Animal Bedding

uses for sawdust shavings and waste chips

We have about 20 chickens at any given time, and while I don’t use sawdust for them, some people do!

Our chickens do enjoy scratching around in the sawdust for insects, but because I use regular chain oil with my saw, I don’t like to put it in their coop. My preference is to use hay.

Most chickens roost to sleep, as ours do, so it’s not like they would be sleeping in it. But I wouldn’t want them laying eggs onto sawdust either. It’s not recommended to put eggs into water because the shells are porous, so why would I want to have eggs sitting in oily sawdust?

It could be used effectively in a chicken house to help soak up the odd dodgy poo.

We also have a rabbit, among other animals, and I wouldn’t use it for them either. As far as I’m concerned, it’s not great for use with animals because of the oil.

This means:

  • not for a cats litter box
  • not for a rat or mouse cage
  • and not for a rabbit hutch

Sawdust has such fine particles as well that it can be breathed in by animals and spread around your house. There are better bedding and litter materials for our animals out there!

Weed Suppressor

what is sawdust used for

Use chainsaw sawdust as a weed suppressor.

I actually vacuumed all this sawdust up with my lawnmower and then have dumped it as a weed suppressor along my front fence (yes, I know I need a new fence). This means it’s a mixture of grass clippings and sawdust which is a bit better if I ever want to plant something along this fence line (once the new fence is in)!

Sawdust can be used along garden paths and other weed-prone areas as well, though remember it can get gunky when soggy.

Mop Up Oil

One of the most practical uses for sawdust: to soak up any oil or fuel spills. I spilled a little bit of bar and chain oil just for this shot!

It’s great for those larger spills as it really does just soak it right up. Once you’ve applied enough sawdust and left it a little while, it can easily be swept up and put in the trash.

Dry Out Old Paint

wood shavings uses

If you have old paint you want to get rid of, you are supposed to dry it out first. Runny paint is apparently more toxic than dry paint.

Some manufacturer instructions that I’ve seen have said to brush out unwanted paint onto newspaper, let it dry, and then throw it away. I’ve never tried to do this, but I imagine it would take a while and could get messy if the wind picked up.

An alternative is to add sawdust or wood shavings to unwanted paint. This soaks up the moisture and will harden the paint up quickly. It’s then able to be disposed of in the trash.

Compostable Toilet

uses for sawdust in the garden

Sawdust is good to use in compostable toilets – though I haven’t tried this one!

It’s always combined with a variety of other items to help break down and compost waste. Other items that are commonly added are coffee grounds, hay or straw, leaves, newspaper, and other organic food scraps.

If you have plenty of it available, however, sawdust can be one of the major ingredients in the stew. These toilets are often called ‘sawdust toilets’ for that very reason. The sawdust is good for soaking up moisture and keeping the mixture from turning into a sloppy mess.

Make Firelighters

how to make sawdust
If you have spare time and like to make things with your hands, you can use sawdust to make firefighters – something else I haven’t personally tried!

There are many for sale in stores that are simply made of sawdust and wax. Most use paraffin wax, but some other types of wax are suitable as well. These are generally non-toxic and come out scented like the wood you have been cutting.

They have a long shelf life and can be used to start your wood fire stove, outdoor campfires, or wood cookers.

Mixing With Cement

And last but not least, you can add sawdust to make a type of concrete.

As stated in the video above, add:

  • 3 scoops of sand
  • 2 scoops of sawdust
  • 1 scoop of cement
  • 1 scoop of lime

This is a special type of construction method and it pays to do your research before trying it out. The resulting concrete is said not to be as strong as that which does not have sawdust.

Sawdust Uses

These are some of the ways to easily recycle and use sawdust around the home.

Using it in moderation in the garden or compost isn’t going to causes any harm, so don’t stress out about that sort of thing. Just don’t overdo it and you’ll be right!

  1. Yeah I’d definitely feel dodgy putting sawdust in my concrete. Hadn’t thought of that possible use but it could work.

  2. Another idea is to use sawdust in a mix to grow seedlings in. I sometimes chuck a bit in with my selling mix and it seems to do it really good.

    • Cool, thanks for the tip. I’ll do a bit more research before trying it out myself. I have a feeling it might be alright for some plant varieties but not for others?
