Juniper's Provenness Rating System

FULLY PROVEN

The process has more than one full commercial reference site that has been operating for at least two years on this feedstock, at a relevant scale. Operational performance has met the client's expectations and the plant has achieved a performance that is consistent with international standards

PROVEN

The process has been proven in sustained commercial operation but in a more limited fashion (the nature of this limitation is described in our comments).

DEMONSTRATED

The integrated process has been demonstrated to operate satisfactorily on the relevant feed material at a pilot or demonstration project, typically in a time-limited trial.
Key performance parameters have been confirmed, though often at less than the targeted scale.

CONCEPTUAL

This rating applies to a process concept for which there is very limited performance data available as yet.
It is also applied when a company is promoting the technology for a new application or in a new configuration.

NOT RATED  

For various reasons we may decide not to give a process a rating (eg there may be unsufficient information available at the present time), in each instance the accompanying text will explain the reasons.

If a rating is (bracketed) this indicates that it has been qualified for some reason, as discussed in the text.
An upward pointing arrow indicates that it is anticipated that the rating may be raised in the near future if developments continue as expected (for example: a plant is currently being commissioned)
An exclamation mark against a rating indicates that Juniper is aware that significant technical, operational or environmental issues were identified at a key reference facility which we believe may be a cause for concern in relation to particular applications
