ASH RECYCLING

The Inashco ash recycling consists of an on-site concentrator (ADR) and a centralized upgrading facility. The ADR together with conventional Eddy Current Separators, produce a fine non-ferrous concentrate and a clean marketable mineral aggregate.

The non-ferrous concentrate is transported to the Inashco proprietary upgrading facility. At the upgrading facility the concentrate is upgraded into high valuable heavy and light non-ferrous metal scrap products.

ADVANTAGES

An important advantage of the Advanced Dry Recovery (ADR) technology is that it can be operated as a stand-alone unit or it can serve as an integrated extension to existing installations, meaning it can easily be added to conventional technology to increase metal recovery dramatically. This means that the dry technology extension can be applied to existing plants without changing the process, preventing high cost required for adjusting or replacing the existing installations.

Furthermore, the ADR provides the possibility to treat ash without extensive aging. Aging reduces the moisture content, but as a negative side effect, it also reduces the amount of aluminium in the ash resulting from oxidation of aluminium into aluminium hydroxide.

The ADR technology can handle high moisture content ash directly from combustion, reducing intermediate storage and enabling the recovery of more aluminum.

THE PROCESS

Recycling of municipal solid waste and combustion of the remaining fraction to generate energy were the two main steps in making waste management more environmentally friendly. Inashco has taken the next step by recovering the full potential of the ash residue. We provide a breakthrough technology that recovers fine non-ferrous metals and produces marketable construction products from the remaining mineral aggregates.

PRODUCTS:

Metals

The effective mining and upgrading of ash results in the production of a variety of metal products.

  • Heavy non-ferrous scrap products
  • Aluminium scrap products
  • Ferrous scrap products

Through our relationship with Fondel these metals find its way into the global metals market. The secondary mining of these metals prevents the exhaustion of our planet.

Minerals

Aggregates treated with the ADR technology can substitute natural aggregates and reduce the cost price of concrete. In the Netherlands the independent committee CUR VC 89 has investigated upgraded bottom ash in concrete since 2008. The technical guideline (CUR 116 bottom ash in concrete) ) is published in 2012.On top of the EN 12620 the CUR 116 gives additional requirements for the use of upgraded bottom ash in concrete

Based on the results of tests performed under the authority of the CUR-committee, up to 50% of aggregates in concrete without reinforcement may be substituted with treated bottom ash. Up to 20% of the aggregates may be substituted in concrete with reinforcement.

The ADR upgrading proces is a dry proces. Our upgraded bottom ash can be used only in concrete without reinforcement, so concrete products like tiles and bricks. Please click here for our product sheet for the precast industry.

Examples of applications:

  • Blocks
  • Bricks & Tiles
  • Pipes
