MinPlus is produced in the patented “Controlled Thermal Conversion” process (CTC) from the otherwise discarded mineral fraction of paper recycling. The process is CO2 neutral. Small particulate lime and clay minerals are re-used in a wide-pore layered highly reactive mineral mixture with a melting point of more than 1.300 °C. The powdery MinPlus additive is pneumatically dispersed into the empty drafts of waste incinerators at typical flue-gas temperatures of 800 – 1.100 °C, where it binds HCl, SO2 and HF upstream of the boiler superheater parts, simultaneously preventing the formation of hard deposits and high-temperature melting corrosion of downstream boiler parts. Dosage rates of typically 1,5 g MinPlus per Nm3 of flue-gas result in significantly increased availability and increased interval length between planned stops, while simultaneously reducing the amounts of traditionally applied flue-gas cleaning additives like lime, sodium hydroxide, or sodium bicarbonate.

Using our unique technology, paper recycling waste streams can now be used to produce clean, CO2-free electricity and a range of valuable, non-toxic mineral products that capture harmful mercury emissions from the world’s coal fired power stations and provide zero carbon admixtures to certain types of cement and lime products.
Originally developed to meet the needs of the Dutch paper industry, we are already using our technology to deliver safe, cost effective solutions to some of the world’s most pressing environmental challenges.
Our technology was originally developed by a consortium of Dutch paper mills during the 1990s as a safe and environmentally friendly disposal method for paper sludges and residues produced by the paper recycling industry.
Traditionally, these waste products were either buried in landfill sites or incinerated in industrial waste processing plants. However, with suitable land scarce in the densely populated Netherlands, and an ever present risk of long term soil and groundwater contamination, the Dutch Government, (through the introduction of both legislation and landfill taxes), began pressuring its domestic paper recycling industry to find an alternative to landfill. While conventional industrial incineration offered a possible solution, concern about dioxin emissions, and widespread protests from local communities made this option both financial and politically unacceptable.
Initial research work on the core process technology commenced in 1992, with early development and demonstration work carried out at the University of Twente in The Netherlands at bench and pilot scale and subsequently at CSIR, Pretoria, South Africa at pilot scale.
In 1995, recognising the potential of the core process technology to capture toxic emissions and heavy metals, MinPlus-CDEM initiated research at the Universities of Arizona and Utah in the United States to develop a high-value application to clean the flue gases produced by coal fired power stations.
The success of the initial research on the core process technology led to permission being granted for a full scale demonstration plant in 1999. Plans were drawn up and ThyssenKrupp was appointed to commence construction. Commissioning took place in 2002 and full-scale commercial operations began in 2005.
In 2007, with commercial operations now firmly established, the original Dutch paper industry participants took the decision to sell their shares in the founding company to the Company’s management team, with funding support from a group of private investors.
We believe that our technology and its key process outputs can help companies worldwide address a broad range of regulatory compliance obligations and environmental challenges, ranging from waste disposal to emissions reduction and mercury abatement, offering green, zero carbon alternatives for cement and lime products.
With the technical performance and commercial potential of our technology established, we are now working hard to drive widespread market adoption.
Given the broad range and substantial scale of the market opportunities open to us we expect that for many applications and geographic markets, the full potential of our technology can be best realised by working in partnership with large industrial groups.
