Recycled Aggregates

[Jezzay]

Hi all, I am due to fit some drainage pipes in 10 acres of fields for my elderly farmer neighbours.
We have enquired about aggregates and have been informed that reycled aggregates are slightly cheaper and more readily available.

As anyone used recycled aggregates before and what precautions do the suppliers put in place prior to crushing it to ensure the recycled aggregate is not contaminated with other building waste (oil, plasterboard, asbestos, plastics and contaminated soil etc).

Any help appreciated.

Never used the recycled stuff but we once played two football matches on a field of broken bricks and stones. We won 5-4 on aggregate.
