Our purpose-built re-refining plant has the capacity to mitigate an estimated 100,000 tonnes of carbon every year.
Glide’s re-refined base oil is estimated to have a carbon footprint at least 50% lower than virgin base oil made from crude oil,* helping reduce reliance on this finite global resource.
*Estimate based on a carbon footprint study by Toitū Envirocare.
To date, waste oil in New Zealand has been burnt as fuel — destroying valuable resources and releasing emissions into our atmosphere.
At Glide, we re-refine waste oil - producing a premium, lower-carbon RRBO (re-refined base oil) that can be reused over and over.
Waste oil contains a range of components - around 70% of which is base oil. At Glide, we recover up to 99% of this base oil and return it to a high-quality product that can be reused indefinitely. The remaining 30% consists mainly of water, light cut, middle distillate and asphalt extender. Through our advanced refining process, these are also recovered and repurposed - ensuring almost 100% of waste oil is reused.
A smarter, cleaner, more circular solution.
Estimated carbon savings data
We give you estimated carbon savings for your collections, calculated using emissions factors from a carbon footprint study by Toitū Envirocare.* Helping you show customers, stakeholders and regulators the positive impact your business is making.
Higher-value outcomes
Re-refining turns waste oil into premium re-usable base oil (alongside other reusable byproducts), reducing reliance on crude and contributing to New Zealand’s economy.
Cost-effective & hassle-free
Glide’s re-refining process comes at no extra cost — just a lower-carbon outcome for the planet, and peace of mind for you.
Our carbon figures are estimates based on a carbon footprint study commissioned by Glide and undertaken by Toitū Envirocare in general accordance with ISO 14067:2018, using a mix of real and estimated data. The study compares Glide re-refined base oil with virgin base oil produced from crude oil and disposed of as low-grade fuel oil. It assumes each litre is at the end of its third reuse cycle, and figures may change as primary data becomes available. The study has not been externally reviewed and does not constitute Toitū certification.
Toitū Envirocare’s summary of the study:
"Toitū have undertaken a study comparing the carbon footprint of the Glide current waste oil reuse scenario and their planned upgrade to a re-refining process plant. The study has used both real and estimated data. Toitū estimate that the re-refining process reduces the carbon footprint of base oil by at least 50% or approximately 2.7 kg CO2e for each litre of re-refined base oil produced, as compared to virgin base oil being produced only from crude oil and disposed of as low-grade fuel oil.
A saving of 2,700 tonnes per each 1 million litres of base oil produced by re-refining is equivalent to approximately 11 million km travelled in an average petrol driven car, or 17,000 one way journeys between Wellington and Auckland.
Whilst the study has been undertaken in general accordance with the ISO 14067:2018 standard and been peer reviewed within Toitū, the carbon footprint has not proceeded to external review due to the amount of estimated data necessarily used in the study and therefore relatively high levels of uncertainty. The results are, however, aligned with similar studies undertaken using actual data overseas. The study also does not account for whether on-sold re-refined oil returns to the New Zealand market."
