About Us

Launched in 1997, the UKQAA is a Trade Body that represents members involved in the supply or use of fly ash from pulverised coal fired power stations. It is well known that all coal fired power production in the UK is expected to cease by 2025.  Indeed, most stations will be closed well before this date.  This has meant that both suppliers and users of fly ash are currently evaluating their future strategy and options.

The UKQAA has also had to adapt and redefine itself for its members.  In the past, the primary objective was promoting the use of fly ash and providing technical support to users and suppliers.  Over the past 2 years the emphasis has changed and is now fully focused on assisting members to identify future sourcing options as well as highlighting best practices and technologies that may facilitate this.

The UKQAA feels that the answer is in the development of landfilled fly ashes from pulverised coal fired power stations. The UKQAA estimates that there are well over 100 million tonnes of landfilled fly ash located at currently operating or recently closed power stations. Subject to being defined as future mineral or pozzolanic reserves, these single source deposits of fly ash in closely defined boundaries can be beneficially used by the construction industry for generations to come.

The UKQAA is working with key stakeholders including the Environment Agency and Planners to safeguard these strategic reserves as well as funding research into understanding the properties of landfilled fly ashes.
