A consultation on a draft Quality Protocol (QP) for the production and use of steel slag aggregates in construction applications has been launched by the Environment Agency (EA).
Steel slag aggregate is a secondary material created during the manufacture of steel. It is currently classified as a waste.
The draft QP sets out end-of-waste criteria, which producers can follow to demonstrate that their steel slag aggregate has been fully recovered and can be considered a product rather than waste.
This will clarify the point at which waste management rules on handling, transport and use cease to apply.
The EA said this will lead to a reduction of regulatory burdens on the agency and on producers and users of steel slag aggregate.
The EA noted the use of steel slag aggregate in the applications detailed in the QP has been assessed as presenting a low environmental risk.
The QP applies to the manufacture of steel and stainless steel in England and Wales
It covers use of best practice in the production, processing, storage, handling, transportation and use of steel slag aggregate.
The EA said there has been a rise in market demand for aggregates in the UK.
It added: “The move to a more sustainable use of non waste aggregates, creates a position in the market for recovered aggregates, including steel slag.”
The QP will provide a “higher degree of market confidence and producer certainty with regard to regulatory controls,” it said.
This is an eight week consultation. The EA has provided an FAQ document for the consultation (file right).
