We are where you are


We ask the right questions, e.g.

• Which kind of feedstock?
• Is there a soot collector?
• Is there a flue gas cleaning or dust separator?
• How are the residues treated?


- Dumping?

- What other kinds?

- If dumping, what is the estimated amount?

- If dumping, is there an interest to recycle the material?

What is the yearly quantity?



We organize the sampling, e.g.

• Procedure for bulk material
• Procedure for stuffed big bags
• Procedure for stored/dumped material



We organize the analysis, e.g.

• Consistence
• Smell
• RFA (X-ray fluorescence analysis)
• ICP (inductively coupled plasma)
• Gas analysis
• Burning the sample


We help for the technical organisation, e.g.


Power plant
  • Process details
  • If burning with Mg, Ammonium, what are the detailed reasons (no stable temperature control, etc.)?
  • How is the situation of residues?

  • Detailed discussion about soot process
  • Detailed discussion about kind of soot
  • Moisture
  • Dehydration
  • Ash
  • How is the Situation of residues?

If dumping
  • Situation?
  • Is the material degradable?



Sourcing scrap and other metals


We help to get the right material, e.g.

  • Copper scrap
  • Aluminum scrap
  • Copper concentrate
  • Molybdenum concentrate

Contract procedure for sourcing and recycling contracts


We support you to build up the contract, e.g.

  • Conformity with possible authorization requirements
  • Packaging procedure
  • Inspection terms (e.g. inspection by SGS)
  • Logistic terms (e.g. frequency of shipment, interruption, destination)
  • Contract terms
  • Obligations of the parties
  • Respectable pricing procedure
  • Payment procedure under consideration of analysis results

Authorities admin for residues material handling


We help with all authorities requirements, e.g.

  • Storage and handling requirements
  • Transportation requirements
  • Notification requirements
  • If necessary: special OECD procedures (see logistics also)
