Climedec Technology


Granules made from disinfected discarded face masks 


Granules made from fly ash generated by incineration in a MSW waste-to-energy plant  

Climedec is a unique and sustainable technology for management of hard to abate and treated waste streams generated in various resource recovery-recycling- disposal chain of operations. Waste streams treated by Climedec can be in solid, liquid, slurry or gaseous forms, including various piles or substrates of solid material that generate and/or emit greenhouse gases (GHGs) and odours considered harmful to environment and human health.

Treatable solid waste streams include residues from treatment of food waste, hazardous ash from various incineration processes (including fly ash from APCr and WtE processes), solid residues from destruction of PFAS in water, soil and sediment, contaminated landfill material (from MSW and C&D operations), mining and mineral processing solid and slurry residues, and ash/dust residue from incineration of plastic and polymeric products such as discarded single-use face masks and livestock bedding waste.

Treatable slurry waste streams include sludge from STPs, whey waste from dairy farms and abattoir waste streams.


Treatable liquid waste streams include reject brine from desalination plants, energy generation plants (coals seam gas, coal bed methane and shale gas), mineral/mineral processing effluents, agricultural wastewaters, food and beverage processing effluents and construction site wastewater.


Treatable gaseous waste streams include emissions from odour and GHG generating and/or emitting substrates such as landfills, STP retention basins, mine tailing dams, and cattle farms, all of which have become increasingly necessary to be treated to minimise adverse impacts on environment and/or public health. 

Through comprehensive on-going performance test work (long-term leaching, physical/mechanical stability tests) carried out over the past few years on the encapsulated waste from various industries, Climedec technology has proven its value as a fit-for-the-purpose solution for a range of hard to abate and already treated waste streams. Thus, our Climedec technology offers a high readiness level for use by industries seeking sustainable solutions for their waste challenges.

The key advantages of the Climedec technology may be summarised as:

  • based on a continuous processes that leads to encapsulation of waste through aggregation and granulation, without the need for any stabiliser or a binder such as polymers and cements

  • capability of the technology to permanently solidify toxic elements contained in the waste through enclosure, stabilisation and controlled mineral conversion processes

  • provide cost effective and sustainable solutions for safe permanent land disposal of secondary waste streams, such as the solid residue generated in PFAS destruction operations

  • technology's flexibility in offering fitness for purpose waste solutions at scale for a diverse range of industries having site specific waste challenges, and

  • potential for valorisation of the encapsulated waste for use as a feedstock for manufacture of a multitude of industrial products and consumer goods.


Considering the above-listed advantages, Climedec potentially offers the most viable management option for hard to treat waste streams, particularly where zero waste is already or becoming regulatory or a corporate requirement. An example relates to fast evolving regulatory requirements for the management PFAS in water, soil and sediment environs that apart effective PFAS destruction using current and developing technologies, there is an overwhelming need for safe permanent disposal of residual solids resulting from PFAS destruction.  Additionally, because of downstream value-adding opportunities for the encapsulated material, the technology offers substantial business benefits unmatched by any other technology.
