Company
Overview
The Creating Value From Waste™ (CVW™) technology is 100% owned by CVW CleanTech Inc. (“CVW CleanTech”), a publicly listed corporation whose common shares are listed on the Toronto Venture Stock Exchange (TSX.V: CVW) and traded on the OTCQX (CVWFF).
CVW CleanTech is a diversified clean tech platform, building a portfolio of exposure to clean technologies in the commodity space including through direct ownership of its proprietary CVW™ technology.
The Company is currently focused on advancing its proprietary technology towards commercialization which will deliver significant environmental and economic benefits to oil sands operators, indigenous communities, and the province of Alberta and Canada.

Technology History
The technology began mineral research and processing at its facility at the Saskatchewan Research Council in Regina, Saskatchewan in 2004 for flow sheet development test work. Encouraging results were achieved and it was decided to further invest in processing fresh froth treatment tailings.
In 2005, the technology was tested via bulk sampling plant by connecting to the fresh froth treatment tailings pipeline on-site in Fort McMurray. The bulk sampling plant produced washed sands containing heavy minerals which were further refined.
In 2006, significant advances were made through process flow sheet design updates, which were then tested by the operation of an on-site modular pilot mineral concentration facility (2006 Pilot Program) during September-October 2006. The 2006 Pilot Program achieved high recoveries of a heavy mineral concentrate (98-99%); however, traces of bitumen remained on the heavy minerals. The removal and recovery of bitumen was demonstrated as essential to effectively recover the heavy minerals.
In 2007, additional R&D activities were performed to remove bitumen from the heavy minerals and recover bitumen from the tailings stream.
From 2008 and 2009, the technology portfolio grew significantly as the engineering team executed on over 20 research projects with 12 independent research organizations. The program was 50% funded by a $3.5M grant from the Government of Alberta and developed new technologies to recover bitumen and solvent from froth treatment tailings and produce a cleaned heavy mineral concentrate.
During 2010 to 2013, the CVW™ technology was tested for the oil sands operators via a $30M pilot. The pilot program was highly successful, recovering over 80% of the bitumen and solvent as well as producing bulk samples of cleaned heavy mineral concentrate for full scale testing. These recoveries demonstrated significant environmental benefits by reducing emissions of greenhouse gases (GHGs) and volatile organic compounds (VOCs).
During 2014 to 2016 the mineral separation related technologies were tested via full-scale demonstration to validate valuable critical minerals recovery potential from froth treatment tailings.
The technology was advanced towards commercialization with Canadian Natural Resources Limited (Canadian Natural) starting in 2017 and completing a FEED with third party engineering firms at the Horizon oil sands site.
The reliability and independence of CVW™’s environmental benefits calculations were advanced. The Delphi Group validated the CO2 equivalent emissions which a CVW™ can abate.
A comprehensive guide to the CVW™ technology can be found in its Process and Technology Overview.
The technology has since been advanced to consider the use of a centralized Mineral Separation Plant to accept feed from multiple oil sands mining sites.
Current R&D activities are focused on developing a rare earth element (REE) process circuit to recover high grade monazite.
