“The value of nanoparticle technologies have historically been difficult to reach. The Motley Fool, not so incorrectly, observed that “Scientists like to joke that the promise of nanotechnology has been five years away for the last 35 years.”

Why Does Small Matter?

BLH Ecology Concepts has spent the past eight years developing and refining a method for the creation and harvesting of extremely small particles in a manner that lends itself to continuous process applications. Our review of the literature confirms that this process represents a significant discovery in the area of nanotechnology and creates an efficient environment for the production of extremely small particles. The process has a broader application than that existing under current techniques and, as a result, expands the types of materials that can be addressed and the number of applications for which these micronized materials may be relevant. This process overcomes many of the limitations of the current techniques including: 1) the inability to produce significant volumes of particles of uniform size through a continuous process and; 2) to harvest/filter particles in a primarily batch environment.


2-20 Microns is Industry
Standard For
Jet Milling and Wet Milling.


Below 100 Nanometers is the BLH Difference for Continuous Nano Production Process.


Changing The Way Matter Is Manipulated.

The promise of the benefits of nanoparticles has been hampered by the inability to produce large volumes of the particles in a cost efficient manner. The patent pending technology developed by BLH Ecology produces particles through a continuous process and permits harvesting of the particles without the use of filters or membranes.

Current Science

To meet the increasing commercial demand for small particles and reap the advantages such particles can impart in a growing catalog of applications, a number of methods, both mechanical and chemical, have been developed for the creation of submicron particles.   

Included among the techniques being pursued and refined are a number of processes that utilize the properties and environment of supercritical carbon dioxide (scCO2) in the creation of nanoparticles, the most widely used of which are Rapid Expansion Supercritical Solution (RESS) and Supercritical Anti-Solvent (SAS).

 Regardless of which current technique is utilized to produce the nanoparticles, that production is limited to labor intensive, low yield batch processed.  Additionally, the recovery of the final particles remains a limitation in any of the current processes.
