Opened 23 Sep 2021


Renergi Pty Ltd propose to build and operate a trial pyrolysis plant in the Shire of Collie.  The rial will run for up to 2 years. 

The proposal involves the treatment of municipal waste and forestry waste via pyrolysis to produce a biochar, condensed bio-oil and wood vinegar. 

The trial plant is small scale and will be constructed within the boundary of the Collie waste facility operated by the Shire of Collie.

Why your views matter

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
