Introduction to Concrete Disposal
There are several methods to dispose of concrete from demolition sites. The best way depends on the scale and quantity of the material.
For small quantities:
- Hire a skip and let someone else deal with it
- Hire a wagon and take it to landfill
For larger quantities:
- Crush it on site and use it a fill
- Sell it or pay a small fee to take it to a waste transfer & recycling centre
The trend of recycling material in transfer stations helps with the disposal of concrete. The advantage for the contractor or homeowner is they do not have to pay landfill tax. If the concrete is clean, the transfer station may take the material for no charge, or could even pay a little for it.
The advantage of the waste transfer station is they can obtain very competitive priced materials to recycle and convert into a profit.
What Percentage of a Demolition Site are Recycled Aggregates?
The percentage of concrete depends on the building or structure being demolished. For example, the recycled aggregates in the demolition of Welling borough Swimming pool in the UK was 75%
For the housing estate at Kings Crescent Estate, Hackney, UK, the percentage was 89%. This site produced 2,680 tonnes of recycled aggregates. The aggregates were crushed and reused on site for fill and concrete production.
The best way to maximise profit from a demolition project is to prepare a pre-demolition audit. The pre-demolition audit will give you the information to plan and negotiate the best methods to deal with the demolition materials.

How To Take Advantage of Concrete Disposal
With a large amount of crushed concrete and aggregates on a construction site, you can make your own concrete rather than buy in ready-mix.
The difference in price in the UK is €30 per m3
The Hackney site above produced 2,680 tonnes of aggregate. If 50% of this was used to make concrete the volume would be around 1,000m3 depending on the mix and use of quarried materials. The saving or profit would be around €30,000
Fibo Intercon manufactures a range of mobile batching plant including 15, 30, 45 m3/hr output.
For a 8 hour shift the plant can produce between 100 to 300 m3 of concrete per day. With a difference of €30 m3 the profit earned can be between €3,000 to €9,000 per day.
The plant is mobile and can be moved from site to site maximising productivity and utilisation.
