In this article, we discuss how to recycle concrete blocks in a safe manner.

How to recycle concrete blocks?

You can recycle concrete blocks in the following ways:

  • Local landfills
  • Call a local mission or charity that builds or improves homes.
  • Post online
  • Recycling centres or businesses
  • Contact a junk hauling business

Benefits of Concrete Recycling

Concrete recycling reduces building waste and extends landfill life while also saving builders money on disposal and tipping costs. 

Concrete may typically be recycled in places close to the demolition of a building site, which minimises transportation expenses. 

When it comes to LEED Green Building certification, employing recycled concrete might help you get points. In certain cases, a recycling operation creates new job possibilities that would not otherwise exist.

How Concrete Is Recycled

Industrial crushing equipment with jaws and massive impactors is used to recycle concrete. 

After the concrete has been broken up, it is usually screened to remove dirt and particles, as well as to separate the large and small aggregate. 

To separate certain materials from crushed concrete, additional procedures and equipment such as water flotation, separators, and magnets may be utilised. 

Pulverising the concrete is another possibility, but it is not always the ideal solution since it makes the separation process more difficult and may result in more contamination from smaller leftovers.

What is the Equipment Used to Recycle Concrete?

When evaluating concrete recycling as a viable alternative, you must also analyse the various choices for crushing the concrete. 

A portable crusher that can be relocated to multiple places or projects is the most practical choice. It’s often ideal to put up a portable crusher in a central area, close to where the concrete is being destroyed yet far enough away from site traffic. 

When selecting processing equipment, consider the following factors:

  • A strong magnetic, water flotation, or an air separator device that can remove steel from concrete should be included in the equipment.
  • It will be easier to set up with separate hydraulic stands.
  • Automatic, manual, or remote control methods are available.
  • Conveyors, jaws, and cones can be used to complete the concrete processing process, from demolition to useable material.

What are the Uses for Old Concrete?

Recycled concrete can be used in many of the same ways as you would use new materials, such as gravel, paving materials, and aggregates. Some of the common uses are:

  • Walkways, driveways, and other outdoor hard surfaces with permeable paving: Broken concrete that has been expertly poured offers a sturdy, porous traffic surface that allows rainwater to drain. This strategy helps to recharge groundwater by reducing the quantity of runoff water that must be controlled by storm sewer systems.
  • Old concrete pavement may be shattered in place and utilised as a base layer for asphalt pavement poured over it, thanks to a process known as rubblization.
  • Material for excavations incorporating underground utility lines as a bed foundation: Gravel is used to cover utility ditches to aid drainage, and broken concrete is an effective, low-cost replacement for gravel.
  • Mixing aggregate for fresh concrete: Some of the fresh (new) aggregate used in ready-mix concrete can be replaced with crushed concrete.
  • Streambank erosion can be controlled by placing larger chunks of crushed concrete along weak stream banks or gullies.
  • Ground concrete can be used to replace river rock or other gravels used as ground coverings and mulch when properly crushed and sorted.
  • Fill for wire gabions: Crushed gravel may be used to create ornamental and useful privacy screen walls or retaining walls using wire cages (gabions).
  • Large slabs of concrete, strategically positioned offshore, can be used to lay the foundation for coral to develop new marine reef ecosystems.

How to recycle concrete blocks?

You can recycle concrete blocks in the following ways:

  • Local landfills
  • Call a local mission or charity that builds or improves homes.
  • Post online
  • Recycling centres or businesses
  • Contact a junk hauling business

We shall discuss these in more detail below.

Local landfills

Use your local landfill to dispose of your used cinder blocks, but first call or check their website for additional information. To use the landfill, you may require a sticker or a pass. 

Expect to pay a charge based on the weight of the items you’re throwing out. Because cinder blocks are so hefty, you might want to think about a different solution.

Call a local mission or charity that builds or improves homes.

Make a phone call to a local mission or charity that constructs or improves homes. For example, Habitat for Humanity could be grateful for a contribution of old cinder blocks as long as they are not damaged.

Post online

Post that you have used cinder blocks for free on websites like Freecycle, Pennysaver, or Craigslist. Make a note of where you reside, whether you’ll deliver the blocks or if they’ll be picked up only, how many you have, and the condition of the blocks.

Recycling centres or businesses


Take your cinder blocks to a concrete-accepting recycling site or company. To find one, go to Earth911.com and search for “concrete” and your zip code in the search boxes. 

Before carrying your cinder blocks there, call the centre or business to be sure it would accept them and if there is a fee for the service.

Contact a junk hauling business

Contact a junk removal company, which may be found in the phone book. They will most likely take up concrete cinder blocks in any condition for a price.

Other ways to dispose of concrete blocks

Other than the options mentioned above, there are also a couple of options for disposing of unused concrete blocks, which depend upon the state of the block.

  • Sort your concrete blocks into two categories: reusable and non-reusable. Chipped or fractured concrete blocks should not be utilised for construction, although they can be recycled.
  • The Green Contractor Guide will help you find green contractors in your area. Call the contractors in your area to check whether they require cinder or concrete blocks for construction jobs.

    Arrange for the blocks to be removed if someone wants them. You save resources since the blocks may be reused in their existing condition without being processed, and you don’t have to transport them in your car for recycling.

Using concrete blocks in your garden

Cement bricks are frequently overlooked. People prefer to overlook or purposefully go past these hefty, plain slabs of concrete in favour of products that are a little simpler to utilise. 

You might reconsider their value after seeing how the blocks can be utilised in a garden. Consider the following options for utilising the extra concrete blocks in your garden.

  • A raised garden bed is one of the most common uses for cinder blocks in the garden. There are many creative designs for this purpose, and cinder blocks are durable enough to survive for years.

    When cinder blocks decompose (which they will eventually), lime can leak into the soil. Line the interior of the garden bed with plastic to avoid this.
  • Use the individual blocks as flower pots instead of constructing a full garden. You may lay them sideways on the ground or use Liquid Nails to create a little wall. For a colourful effect, paint the blocks different colours or leave them natural.
  • By stacking two or three layers of blocks in the garden, you may create a stunning seating area (depending on how tall you want it). A large bench cushion and ornamental cushions complete the look.
  • By stacking cement blocks on a concrete foundation, you can make your own backyard campfire for less than $100.
  • With a little imagination and a lot of cinder blocks, you can make a practical garden wall. The fact that it won’t be blown over by the next windstorm is a positive.
  • If you enjoy the idea of a cinder block bench but prefer something a bit lighter, consider placing many blocks on end (six for each end) and inserting wooden 4-by-4s into the holes to create a seating area. Add colour and pillows, including a bench cushion, to brighten it up.
  • Is your landscape in desperate need of a splash of colour? Try building a skyscraper out of cement blocks. (Make certain they’re both sturdy and glued together.) Paint, cutouts, and beads can be used to embellish the tower.
  • Create a fence around the garden with piled bricks. By carefully positioning the posts through the holes, you may create broader or narrower sections in the fence.
  • By stacking cinder blocks along an inclination, you may create basic steps in your garden.

    You’ll need to measure and plan, but not having to build typical steps will save you a lot of time. Fill the inside with a variety of coloured stones.
  • Create a distinctive garden edging using cement blocks to keep dirt or pebbles in your garden and off the rest of your yard.

    The end result, especially if you elect to put additional plants inside the blocks, may be quite lovely.

FAQs

Is a concrete block house good?

Yes, a house built from concrete blocks is good. The combination of a concrete wall structure and insulation generates a tight thermal building envelope that saves energy. 

According to EPA statistics, the average American spends 90% of their time indoors, making it critical that houses are as healthy as possible. 

Toxins, moulds, outdoor allergens, and radon are all reduced in a healthy house by using materials that reduce occupant exposure. 

Concrete emits less volatile organic compounds (VOCs), is mould-resistant, and reduces allergy penetration from the outside. When opposed to wood walls, insulated concrete walls reduce the spread of flames in the event of a fire. 

Like steel, insulated concrete block walls do not burn, bend, or soften. Termites, carpenter ants, and rodents are less attracted to concrete home building than they are to wood construction.

Is it better to build with concrete or wood?

It is better to build with concrete than with wood. Although wood is a less expensive option than concrete, it ages more quickly and requires more upkeep and repair. 

As a result, although wood deteriorates fast, especially if not properly maintained, concrete has a two to three times longer lifespan than most other construction materials.
