Summary:[Display omitted] •HDPE and LDPE were converted via HTP into clean waxes and ultra-low-sulfur fuels.•Reaction pathways were proposed based on GC × GC analysis of intermediates.•Products qualified as No.1 diesel, No.2 diesel, or gasoline blendstocks.•HTP diesel had high cetane number and low aromatic content.•Energy efficiency and GHG emissions were better than incineration and pyrolysis.
