Open primary source ↗Additive Performance CentreA practical additive-supplier qualification system
Qualification should connect technical evidence, manufacturing control, traceability and change management rather than rely on a one-time sample.
Read article →Circular Economy & RRBO CentreCan an RRBO project make commercial sense?
No universal RRBO return exists. Viability depends on controlled feedstock, achieved yield, plant configuration, product quality, residue cost, customer qualification and contracted demand.
Read article →Additive Performance CentreChemical similarity is not performance equivalence
Elemental analysis and compositional resemblance can support an investigation. They cannot replace application-relevant performance evidence.
Read article →Circular Economy & RRBO CentreContamination triage for ULO: water, fuel, glycol, solvents and metals
A staged screening framework for safe unloading and feedstock routing that explains both the value and limitations of common laboratory tests.

How to build a defensible incoming-feed specification covering representative sampling, analytical methods, decision rules, quarantine and supplier performance.
Read article →Circular Economy & RRBO CentreFormulating finished lubricants with re-refined base stocks
RRBO can support technically sound finished lubricants, but it must enter the formulation through controlled base-stock qualification, current interchange rules and performance validation.
Read article →Emissions & Future Technology CentreFrom Euro 7 rule to lubricant question
Emissions legislation defines vehicle obligations. Lubricant consequences must be traced through hardware, calibration and OEM requirements rather than asserted directly from the regulation.
Read article →Circular Economy & RRBO CentreFrom generator to guard tank: chain of custody for ULO
A control framework connecting every physical load, sample, tank movement and processing record while explaining why mass balance alone cannot prove material identity.
Read article →Asian Specifications CentreHow the JASO engine-oil families differ
Motorcycle four-stroke, two-stroke and automotive diesel oils sit under different JASO standards, classifications and filing arrangements. They should never be treated as one specification ladder.
Read article →Sustainable Packaging CentreHow to compare lubricant packaging formats without misleading results
Bottles, pails, drums, IBCs, returnable packs and bulk delivery must be compared on the same service delivered, not package weight alone.
Read article →Circular Economy & RRBO CentreHow to qualify RRBO quality and consistency
A single certificate of analysis is a batch snapshot. Dependable RRBO procurement requires an intended-use specification, multi-batch evidence, process control, contamination screening and formal change management.
Read article →Asian Specifications CentreHow to read Chinese lubricant standards without false cross-equivalence
A Chinese standard number identifies a specific document and status. It is not enough to describe a product simply as meeting a generic ‘China specification’.
Read article →Emissions & Future Technology CentreLow-SAPS is a system-design choice, not a synonym for better oil
Ash, phosphorus and sulphur constraints protect emissions systems, but the finished oil must still balance wear, deposits, oxidation and durability.
Read article →Circular Economy & RRBO CentreRRBO is not a finished-lubricant specification
Re-refined base oil can be a valuable formulation input, but origin alone does not establish the performance of the finished product.
Read article →Circular Economy & RRBO CentreUsed oil is not one legal category
Used-oil regulation changes across jurisdictions and across the material's journey. Collection, treatment, movement, end-of-waste status and finished-lubricant claims require separate evidence.
Read article →Circular Economy & RRBO CentreUsed-oil quality begins at collection, not at the re-refinery
Segregation, storage and chain of custody determine whether a used-oil stream can become dependable re-refining feedstock.
Read article →Circular Economy & RRBO CentreWhat re-refining processes actually remove
Re-refining is a treatment train, not a single purification step. Pretreatment, distillation, extraction, adsorption and hydrogen finishing address different contaminant classes and create different residual streams.
Read article →Sustainable Packaging CentreWhat responsible lubricant packaging must protect
A lighter or more recyclable pack is not sustainable if it leaks, contaminates recycling streams or fails to protect product authenticity.
Read article →Circular Economy & RRBO CentreWhen is RRBO environmentally better?
RRBO can offer environmental benefits, but the result depends on the question, geography, process, energy system, allocation method, product performance and comparator.
