Contributing to the

Circularity

of IBA

Who we are

We are leaders in recovering value from Incinerator Bottom Ash (IBA), a residue from the waste to energy process. Founded in 1999 we provide ourselves on delivering the best performing metal extraction in the market through our flagship IBA recycling facilities in the Midlands.

We recover metals that are re-used as a secondary raw material in manufacturing. The remaining material is used to produce a quality-assured manufactured aggregate suitable for a variety of applications in the construction sector.

Our Mission

Our mission is to extract maximum value from Incinerator Bottom Ash to deliver sustainable, reliable and innovative products and services to our customers

Customer Focus

Solution provider for the waste to energy industry Through years of commitment and innovation, we have established one of Europe’s most sophisticated IBA recycling facilities, setting new benchmarks for the industry. Combined with our high service levels demonstrated by a Net Promoter Score of 81 we are the partner choice for any waste to energy business.

Reliable supply of sustainable materials We ensure a consistent, supply of high-quality IBA aggregate as a sustainable alternative to primary aggregates. This helps our customers meet sustainability targets and reduce environmental impact, supporting circular economy goals.

Logistics and on-time delivery With an established fleet we offer reliable transport and delivery solutions, reducing lead times and ensuring projects stay on schedule. We also support large-volume orders, ideal for infrastructure works like roads, embankments, and bulk fill.

Technical expertise and compliance support: We guide customers on the use of IBA Aggregate, helping them comply with RPS247, which governs its use, helping customers use the materials compliantly.

Our USPs

  • A unique process that extracts minerals, along with ferrous and non-ferrous metals, from Incinerator Bottom Ash (IBA) to offer a more sustainable and cost-effective range of quality products to the manufacturing and construction sectors.

  • With more than 25 years of experience in the industry, we have acquired essential knowledge and expertise. This has enabled us to adapt to changing times, innovate, enhance our processes, and broaden our range of services.

  • Through years of commitment and innovation, we have established one of Europe’s most sophisticated IBA recycling facilities, setting new benchmarks for the industry.

  • Our products feature low embodied carbon levels, are supported by environmental product declarations and sequestrate carbon. This makes them a more sustainable choice compared to recycled and quarried materials.

  • A reliable, year-round supply of products that meet the specifications for highways 600 and 800 – in contrast to recycled aggregates that depend on demolition and excavation activities.

  • In cement and concrete or brick production, pulverised fly ash and blast furnace slag are important raw materials. With reducing stocks due to coal no longer being burnt in the UK, our products are a viable alternative, that also reduces the need for mining.

  • In clinker production, a raw material in cement, IBAA (as an alternative raw material) has beneficial chemistry. IBAA is also pozzolanaic, so can be used as a supplementary cementitious material, reducing the need for cement in concrete production.

Sustainability: We are committed to protecting the environment by recovering raw materials from waste ash to create our products, conserve resources, and promote circular economy practices.
