Recyclable Concrete: 4 Types of Concrete Waste

4 Types of recyclable concrete waste you can dispose of with us

Most people know that recycling is important. We’ve had “reduce, reuse, recycle” drilled into us since about the 70s!

But a lot of people simply don’t know what they can recycle and where. As a result, a large portion of waste that’s recyclable ends up in landfill – and that has a negative effect on both the environment and the cost of doing business.

Fortunately, recycling concrete is a lot simpler than figuring out what plastics go in the yellow lid bin, or whether you can put grass clippings in the red lid bin. Or is it the green lid bin?

Most of the time, you can drop your concrete waste off at a local concrete recycling facility, like ours. Or organise a service provider (like a skip bin company) that will store and transport the waste for you.

But what types of concrete waste can you recycle? And what do you do with the rest of your waste?

Let’s take a closer look at the four main types of product we regularly recycle at our facility. And where you can take some other common types of construction and demolition waste. You’ll be recycling concrete like a pro in no time!

1. Concrete blocks and slabs

Concrete blocks and slabs are ideal for recycling. They’re bulky, which means they take up a lot of space in your demolition yard or skip bins. Which means you’ll need to pay for bigger skips or get them emptied more frequently.

And they’re heavy. If you took a load of concrete slabs or blocks to council facilities, you’d be paying around $28.00/tonne (approximately $20 per m3 )to dump at Moreton Bay Council owned tips, compared to $11.00 per m3 at Moreton Bay Recycling (price correct September, 2021). The cost difference can quickly add up.

Note: if you have oversized concrete, be sure to ring ahead so we can provide a quote. If you’re not sure whether your load is oversized, call ahead to check.

Concrete + steel? No problem. We’re equipped with machinery that can break up large blocks and slabs. This means we can extract reinforcement steel from concrete slabs and send the metal to another specialist recycling facility.

2. Concrete rubble

Most demolition sites need to dispose of large quantities of concrete rubble. This could include a mixture of broken up slabs, bricks, roof tiles, outdoor pavers, walls, driveways, and paths.

As long as your rubble is relatively clean and not contaminated with large amounts of plastic, dirt, garden waste, and rubbish, we’ll be able to recycle it here at Moreton Bay Recycling. In some cases where a load is contaminated, we may still accept it, but will charge a sorting fee to cover the extra handling.

The best way to avoid contaminating your concrete rubble is by hiring a dedicated skip bin for concrete waste. Communicate with all contractors onsite to ensure they separate their waste and use the appropriate bins. Or spend some extra time when loading up your trucks by only loading clean product into the truck that’s headed to the recycling facility. The extra time upfront will save you time and money in the long run.

3. Bricks, roof tiles, and pavers

Don’t throw leftover building materials into general waste. If you can’t reuse the bricks, pavers, or roof tiles on another job, recycle them at a concrete recycling facility. You might even end up repurposing the recycled concrete products elsewhere on the same jobsite!

Bricks, tiles, and pavers are often made from a mixture of materials, including clay, sand, lime, fly ash, ceramic, and concrete. We accept building materials made from sand, clay, and concrete for crushing, but we can’t take ceramic tiles.

Modern roof tiles and cladding are generally made from concrete, making them ideal for recycling. However, it goes without saying that if you’re demolishing an older home, you must first check for asbestos, as this can be present in a number of materials, including roof tiles. Asbestos should be disposed of with appropriate protective measures and should not be recycled.

4. Concrete slurry

If you’ve got leftover concrete in your pump truck or concrete mixer truck, it’s important to dispose of it properly. You can’t just dump it on the ground at the jobsite where it could make a mess. And you need to be careful that it doesn’t contaminate waterways or block up drain pipes.

The simplest option is to find a nearby concrete recycling facility like Moreton Bay Recycling. We have a dedicated area where you can dump concrete slurry, and pump washout stations so you can easily clean your equipment before you drive away.

What don’t we recycle?

Although we can handle small quantities of contaminated waste, we generally turn away loads that contain dirt, soil, clay dirt, plastic, rubbish, and ceramic tiles. Learn more about acceptable materials for dumping here.

If you need to dispose of a variety of waste types in one trip, you can head 5 minutes down the road to the council waste facility at Dakabin after you drop your concrete with us.
