Focussing on the re-use of critical raw materials

Projects

CCWood, Wood Polymer Composite technology

Since 2006 we concentrate our experience with cellulosic materials on sustainable natural fiber modifications to achieve durable Wood Plastic Composites (WPCs) in various constructive applications. The technology that we developed significantly improves the mechanical WPC structures and the long-term bioresistance. At present we are scaling up the proprietary recipes for market introduction under the trade name CCWood.
The Unique Selling Point claims are the following:

  1. Superior hydrophobicity of the wood pulp and in the WPC
  2. Highly reduced corrosiveness of WPC due to absence of acid and moisture
  3. Higher proportion of softwood pulp potential
  4. Superior flexural, tensile and Charpy index testing results
  5. Microbiological stability against outdoor fungi (white and brown rot) during at least 25 years due, among others, to the intrinsic hydrophobicity of the matrix.

REEcover

Financed by the EU’s 7th Framework Programme the Pan-European consortium REEcover develops innovative technology to achieve Rare Earths Elements security of supply by focusing on recovery of rare earths from the electronics industry, mining effluents and magnetic storage devices.

In particular, REEcover was set up aiming to:

  • Improve European supply of the critical Rare Earth Elements Yttrium, Neodymium, Terbium and Dysprosium
  • Strengthen SME positions in Rare Earth Elements (REE) production and recovery value chain
  • Innovate and research two different routes for hydro/pyro metallurgical recovery of REEs: as Rare Earth Oxides (REO) or Rare Earth Oxy-Carbides (REOC) in electrolytic reduction
  • Demonstrate and compare viability and potential for these routes on two different types of deposited industrial wastes:
    • tailings from the iron ore industry (high volume but low concentration of REE). During iron ore production of magnetite concentrates tailings are being removed and deposited, and can be “remined” for their content of valuable REEs.
    • magnetic waste material from the Waste Electrical and Electronic Equipment (WEEE) recycling industry (low volume but high concentration REE).  REE’s in WEEE-products (e.g. hard disks) end up in magnetic waste and subsequently in slag or dust from steelmaking or base metal smelters.

Chemconserve plays a supervisory role in mastering the potentially resulting technology and its licensing options. Some 14 EU organisations including SMEs and Universities undertake this challenging effort scheduled to be completed by 2016.

 

TPPO Recycling

Given our direct interest in Triphenylphosphine Oxide (TPPO), already since 1998, we undertake a research effort to develop an economical process route to recycle TPPO back to its origin of TPP. In this way important quantities of phosphor residues are preserved, and can be reused.
We work together with the Vrije Universiteit Amsterdam focussing on Phosphoric recycles.


Re conserve.jpgREconserve
REconserve is a recycling technology owned by Chemconserve BV for rare earths from fluorescent powders from end-of-life lamps and CRTs.   It concerns a unique technology to recycle and purify for reuse in industry the oxides of the rare earths yttrium and europium from the fluorescent materials contained in lamps and cathode ray tubes (CRT) from televisions and computer screens.
REconserve, together with industrial partners from Spain, Germany and the UK developed this innovative rare earth recycling technology under the auspices of the late Mr. Dim Kesber in the context of a European Commission funded project. This resulted in a directly applicable technology for recycling rare earths from fluorescent powder. The technology was developed and tested successfully at pilot-scale for over a year and resulted in a complete basic design for a full-scale plant. A detailed process description and an investment budget for scaling up to industrial scale were elaborated by the chemical processing experts involved in the project.
