Microwave Assisted Processing (MAP™)

Radient's patented, proprietary Microwave Assisted Processing or MAP™ technology is based on the selective and localized heating of the moisture present in all natural materials using microwaves as the energy source.

In general, microwaves interact with materials in three ways: 

  1. Reflective materials such as metals do not heat (i.e. they do not absorb energy, but rather reflect the energy).
  2. Transparent materials such as most liquids other than water do not heat or reflect. Microwaves pass right through them and are only absorbed to a small extent.
  3. Absorptive materials such as water absorb microwaves and are heated.

Microwaves do not heat by conduction or convection but rather dielectrically, which in simple terms means microwaves create heat when a material stops or slows the radiation causing it to deposit some of its energy, which is subsequently dissipated as heat.  Because microwaves interact directly with the object being heated and because this interaction is related to both the chemical and dielectric properties of the object, it is possible to apply heat (or more precisely, energy) in ways that are not achievable by any other means.  Furthermore, every material will absorb microwave energy to a different extent, with individual parts of that material will absorbing the energy differently.

Radient's technological advantage and expertise in selectively depositing microwave energy into different parts of a biomass' complicated chemical system form the core of our extraction advantage.


MAP™ Manufacturing Facility

Radient's 1,800 square meter  MAP™ Manufacturing Facility is located in Edmonton, Alberta, Canada, 30 minutes from Edmonton International Airport.  

In addition to being a showcase of the equipment, processes, and technologies that make up the MAP™ solution, the facility is also 

  • ISO/GMP-compliant
  • capable of processing up to five metric tons per day of biomass, across a range of biomasses
  • includes a pilot-scale plant capable of processing 500-800kg/day of biomass for very high-value extracts


What types of inputs are compatible with Radient's proprietary extraction process?

Applicability has been established across a broad range of natural biomass inputs including plant matter, algae, fungi. microbial biomass. The starting material needs to be solid but can be dried, as long as the residual water content is greater than 5%.

Does Radient specialize in particular types of products?

Radient has a great deal of experience in extracting, isolating and purifying food/nutraceutical ingredients (colourings, flavourings, preservatives etc) and pharmaceutical raw materials.

Are there any products for which the Radient extraction technology is not suitable?

We do not recommend using the microwave technology to extract proteins, carbohydrates or nucleic acids.

Can Radient process fermentation broths?

The Radient extraction technology can process fermentation-derived cake (biomass) but not liquid broth. Radient does not possess in-house fermentation capacity, but is able to sub-contract fermentation to collaborators.

What types of solvents are compatible with Radient's proprietary extraction process?

Radient's extraction process has successfully used a wide variety of solvents including ethanol, hexane, acetone, etc, as well as mixtures of solvents or solvents and water. Highly aqueous or polar solvents are typically not suitable.

What type of facilities does Radient operate out of?

Radient has two facilities located in Edmonton, Alberta, Canada. Our 1,500 square meter head office and development center and our 1,800 square meter manufacturing facility. Our manufacturing facility has a NHP site license and we use a GMP-compliant quality manufacturing system.

Who owns Radient?

Radient is public company and trades on the TSX Venture exchange. Our stock symbol is RTI.

When was Radient established?

Radient was formed in June 2001.
