Onsite aggregate recycling

The latest in a series of Calls for Innovation seeks potential solutions to a problem area identified by a gas distribution network (GDN) with a focus on recycling spoil on site.


The UK utility industry is one of the largest users of labour, materials and transport and works across the country to repair or renew underground networks that provide energy, water and telecommunications to domestic and commercial customers.


It is estimated that the industry produces approximately 4.8 million tonnes of construction waste as a consequence of excavation work. It is important that any recycled reinstatement materials are produced and utilised in accordance with the relevant reinstatement standards. In addition, all recycled aggregates used must be compliant with the recycled Aggregate Quality Protocol to ensure they are meet waste legislation requirements.


The major impact for network operators is financial as spoil must be transported and disposal fees paid, and reinstatement materials (virgin or recycled) purchased and transported back to site. This process is inefficient and has environmental consequences, including vehicle emissions which impact air quality and contribute to climate change.


It is envisaged that a transient mobile solution for the onsite recycling of spoil can be found, eliminating the need to transport aggregate to recycling centres.
