At a time where we are all more aware of the consequences our decisions have on the environment, many businesses are taking care to ensure the choices they make promote environmental sustainability instead of devaluing it. As one of the world’s most used materials, concrete can create large quantities of landfill and waste, and as such, recycling it is more environmentally friendly.
How is concrete recycled?
The process of recycling concrete involves crushing it in the jaws and large impactors of industrial crushing equipment. After the concrete is broken, a secondary impactor crushes it further. The concrete is then screened, removing dirt and particles and separating large and small aggregate. If other specific elements are wanted to be removed from the concrete, additional equipment and processes, such as magnets and separators, may be used to achieve that.
Alternatively, concrete may be pulverised, but this is not always recommended as it often complicates the separation process, therefore potentially allowing for contamination within the concrete.
Uses for Recycled Concrete
Concrete is the second most consumed material in the world, after water. However, as buildings are constantly being constructed and demolished, concrete often ends up in landfill or rubbish tips, sitting wasted when it could be put to better uses. These are just some of the possibilities.
- A layer of gravel ensures stability when building new roads. Reduce construction costs by using recycled concrete as a layer of gravel in the construction of new roads.
- Mixing crushed concrete in as an aggregate can mean less cement is needed, reducing costs in the building process.
- Recycled concrete is well-loved in landscaping. Whether it’s raised garden beds, paving walkways and driveways or creating striking features, it’ll find it’s place in a garden. Using recycled concrete to retain walls is also commonplace. The best part about using recycled concrete in garden renovations is that it is priced affordably, saving money whilst helping the environment.
- Recycled concrete is ideal for drainage cells, run-off and erosion affected areas where drainage needs to be considered as a top priority. Concrete aggregates also provide an ideal alternative to gravel in areas where drainage is important.
- Extra stability. Recycled concrete is great when used in retaining walls, controlling erosion in places that may be structurally unsound.
- Prevent the erosion of river banks and other structures at the edges of water.
