Designed in-house by our engineers, our processing plants are manufactured as bespoke machinery, meaning we are always one step ahead of the competition in metal recovery, quality of the IBA produced, reliability and throughput rates.

We offer the full treatment solution or modular components to improve existing treatment performance.

We treat 1.4 million tonnes of IBA per year!

We’ve embraced ISO certifications in 9001, 14001, and 45001 to demonstrate our unwavering commitment to quality, environmental responsibility, and occupational health and safety.

Uses for bottom ash

Ash Processing

The bottom ash created by the incineration process contains metal, which we extract and process.

When you choose Meldgaard as your ash processor, we process and sell all the metals and then openly share the revenue and profits with you.

We’re also able to transform your IBA into aggregate, your ticket to the circular economy.

In addition to a low carbon footprint, Meldgaard Recycling solutions of ash to aggregate gives you the following high-performance and flexible benefits:

  • 80-125tonnes of ash processed per hour
  • 5-7 eddy current magnets ensure maximum non-ferrous metal extraction
  • 2-3 ferrous magnets
  • Sensor sorting system for stainless steel sorting
  • Our mobile plant can come to your site
  • Meldgaard’s own metal plants sort and clean into 54 different metal fractions
  • Ash aggregate is sold back into the construction industry
  • Replacement of virgin materials

Applying the latest tech to solve the problem of waste created by the incineration process, we process 1.4 million tonnes of ash each year, removing the metal and recycling it, as well as creating a useful aggregate product from the remaining ash.


We buy and sell metals from Waste-to-Energy plants such as copper, brass, aluminum, zink, stainless steel, and scrap iron.

We value high quality in our end products

Come and see one of our ash recycling plants or our Kolding site in Denmark, where we process the metals we extract using eddy currents into more than 50 different fractions.

The factory is continuously expanded and developed for optimal separating of metals from incinerator bottom ash.

We can be operational with you as quick as 3 months.

Stationary IBA Recycling Plant

We operate several stationary ash recycling plants, both standalone as well as integrated in our client’s Waste-to-Energy plants.

With our bespoke design we can engineer the IBA plant to fit into the Waste-to-Energy plant’s processes for ash handling. The plants separate up to 98% of all non-ferrous and ferrous metals from the bottom ash. The iron and metals are then ready to be recycled.
