We treat oily and contaminated sump waste by removing hydrocarbons, solids, and oils. The recovered water is reused, while contaminants are responsibly processed to reduce environmental impact.
We safely process black oil by separating and recycling its water for use in our operations, while the remaining oil is exported for specialist refining into reusable fuel—turning waste into a valuable resource.
We dewater low contaminated sump waste, recycle the cleaned water through our clarifiers, and bulk the remaining solids with sawdust and cleanfill—creating a stable, reusable material.
Cleanfill is blended with waste solids to dilute contaminants and create a safe, stable product suitable for cleanfill disposal.
We use sawdust as a natural bulking agent to stabilise sump waste solids, lowering contamination levels and making the material reusable or compostable.
We process bilge and ballast waste just like black oil—separating and recycling the water for reuse, while exporting the remaining oil for refining into reusable fuel.
We filter used cooking oil to remove food waste, keeping it in the South Island where it’s remade into sustainable biodiesel.
We separate and recover valuable fractions from antifreeze and coolant, with safe treatment of residues for sustainable disposal.
We recover usable hydrocarbons from contaminated fuel and ensure safe, sustainable treatment of all residues in compliance with environmental standards.
We collect, press, and recover oil from used filters, with the metal recycled locally through scrap partners — keeping resources in use and waste out of landfill.
We recover usable fractions from hydraulic oil and safely separate residues, offering businesses a sustainable and compliant disposal solution.
We safely separate used cutting oil, recovering valuable fractions while responsibly managing residues to keep waste out of landfill.
