Developer behind waste pyrolysis trial wants to keep it quiet.

Scrap metal recycler Rob Ofsoski, owner of a company conducting trials at a waste-to-energy (WtE) plant in the Bay of Plenty, says he doesn’t want anything written about it at this stage.

That’s for a number of reasons, mainly “commercial sensitivity”, he says.

“I’m not talking to anyone.”

Ofsoski is the ultimate owner of Rainbow Mountain Renewable Energy, which received a discharge to air resource consent in 2022 for a six-month trial of the equipment for a pyrolysis plant at Waimangu in the Bay of Plenty. 

He’s been involved in the scrap metal industry for more than 40 years and his main business, Metalco Recyclers, imports and exports metals and machinery.

Rainbow plans to process tyres, plastics, and automotive flock through the WtE plant. Pyrolysis is a process of applying intense heat to waste in the absence of oxygen and the materials decompose, producing gas, oil, and char.
