Circularity and critical materials: from ambition to evidence
Independent advice grounded in materials engineering, metrics and economics.
Why Hoskins
Two sides of resource security
Criticality shows which materials put your supply at risk. Circularity is one of the strongest levers for reducing that risk.
Both start with knowing what your products are made of.
Advice and support for governments, industries and businesses
-
I co-developed the Material Circularity Indicator with the Ellen MacArthur Foundation. Its results now appear in over 500 verified product listings in Environmental Product Declarations across Australia and New Zealand.
-
I've worked on material supply risk since 2010. I developed a compositionally aggregated method that assesses risk across a whole bill of materials, and I serve on the UK Critical Minerals Expert Committee and the advisory board of the International Round Table on Materials Criticality.
-
I'm a contributing author of ISO 59020:2024 and a national expert to ISO/TC 323, Circular economy.

What I do
For manufacturers making product claims, building and fitout teams, procurement and supply-chain leads, and government and industry bodies who need circularity and supply-risk evidence that stands up:
-
Expert counsel on call: opinions on circularity claims and regulations, peer review, executive advice and leadership workshops.
-
Fixed scope, defensible results: circularity strategy, KPIs, ISO 59000 implementation, green building ratings, material supply risk, recycled content and MCI assessments.
-
Build in-house capability: masterclasses, corporate programmes, industry workshops and keynotes.
Have a claim to test, a risk to understand or a strategy to build?
Tools you can use now
Hoskins has a range of free and paid tools to help you
Ocean Plastics
How ocean plastic accumulates. Adjust production, leakage and clean-up to see why plastic persists, and why only closing the leakage pathway changes the outcome.
Critical Minerals
Mineral supply risk. Production concentration and governance risk for 78 mined resources, 1996 to 2024, compared with nine governments' critical-minerals lists.

MCI Calculator
A browser-based Material Circularity Indicator calculator by subscription. Meanwhile, the free, basic Excel MCI calculator remains available to download here.
MCI Registry
Published MCI results. Verified MCI results from Australasian EPDs, plus self-declared values, plotted point by point and searchable by producer, product and region.
Critical Materials
Material supply risk. Supply risks applied to alloys, batteries and other real materials. How could a change in supply impact the availability of the materials you rely on?
