A Standards-Guided Approach for Formalizing Product Circularity Assessment Metrics

July 3, 2025
Author(s)
Junwon Ko, Sandwana Sneethan, Gisele Bortolaz Guedes, Fazleena Badurdeen, I.S. Jawahir, Buddhika Hapuwatte, Katherine Morris
The industrial transition towards a more sustainable Circular Economy (CE) emphasizes the need for products that align with CE principles and robust methods for assessing their circularity performance. However, ambiguities between metrics vs. indicators

From Principles to Practice: Product Design Foundations for a Circular Economy

January 23, 2025
Author(s)
Buddhika Hapuwatte, Noah Last, Sami Karsli, Gaurav Aher, Katherine Morris, Vincenzo Ferrero
A circular economy moves from the current linear model of production and consumption, i.e., the take-make-use-dispose model, to one that uses resources efficiently, avoids pollution, and creates triple bottom line (i.e., economic, environmental, and social

A Systems-Based Framework for Product Circularity Assessment

January 7, 2025
Author(s)
Gisele Bortolaz Guedes, Junwon Ko, Fazleena Badurdeen, I.S. Jawahir, Katherine Morris, Vincenzo Ferrero, Ardeshir Mashhadi, Ryan Bradley
One of the key aspects of Circular Economy (CE), particularly when focusing on the product level, lies in its emphasis on designing products to facilitate the circulation of resources and maximize value throughout their entire lifecycle. To effectively

Current State and Emerging Trends in Advanced Manufacturing: Process Technologies

November 13, 2024
Author(s)
Kamyar Raoufi, Karl Haapala, John Sutherland, Fu Zhao, Andres Clarens, Jeremy Rickli, Zhaoyan Fan, Haihong Huang, Yue Wang, Wo Jae Lee, Nehika Mathur, Matthew Triebe, Sai Srinivas Desabathina
Advanced manufacturing is challenging engineering perceptions of how to innovate and compete. The need for manufacturers to rapidly respond to changing requirements and demands; obtain, store, and interpret large volumes of data and information; and

Transitioning Towards Circular Consumer Electronics Products

November 13, 2024
Author(s)
Junwon Ko, Gisele Bortolaz Guedes, Fazleena Badurdeen, I.S. Jawahir, Katherine Morris, Vincenzo Ferrero
The adoption of Circular Economy (CE) practices is continuing to gain momentum, driven by its potential to promote efficient use of resources, maximize the value of materials and products, and mitigate issues such as resource scarcity, environmental

The U.S. Plastics Recycling Economy: Current State, Challenges, and Opportunities

October 30, 2024
Author(s)
Douglas Thomas, Joshua D. Kneifel, David Butry
This report builds upon NIST AMS 100-48 (Thomas 2022), which examined the economics of increased circularity in the economy, focusing on the processes, forces, and decision making that result in an unsustainable economy. This report further discusses the

Towards Sustainable Electronics: Exploring IC Reuse for Circular Economy Transformation

August 22, 2024
Author(s)
Nowell Stoddard, Lisa Paterson, Mark Schaffer, Tom Etheridge, Nehika Mathur, KC Morris, Lise Laurin, Amos Ncube
This perspective paper addresses the importance of responsible end of life (EOL) management of integrated circuits (ICs or chips), with a particular focus on the possibility of IC reuse as an avenue to address the high impacts of chip manufacturing and the

A Critical Analysis of Circular Product Attributes and Limitations of Product Circularity Assessment Methods

May 29, 2024
Author(s)
Junwon Ko, Gisele Bortolaz Guedes, Fazleena Badurdeen, I.S. Jawahir, KC Morris, Vincenzo Ferrero, Buddhika Hapuwatte, Ryan Bradley, Ardeshir Mashhadi
The Circular Economy (CE) has been proposed as a strategy to promote the efficient use of resources, maximizing the benefits derived from materials and products through value recovery strategies, and minimizing waste generation. However, ambiguity remains

Recovery pathway assessment of recycled HDPE for circular economy: Shorter-life vs longer-life products

May 7, 2024
Author(s)
Buddhika Hapuwatte, Ashley Hartwell, Matthew Triebe, Abheek Chatterjee, Nehika Mathur, Daniel Figola, Katherine Morris
High Density Polyethylene (HDPE) is a highly recyclable thermoplastic comprising 17% of all plastic produced. Yet, demand for recycled HDPE (r-HDPE) has outrun availability, partly due to manufacturers' interest in meeting sustainability goals and recycled

Life-Cycle Analysis Datasets for Regionalized Plastic Pathways

February 1, 2024
Author(s)
Taemin Kim, Pahola Benavides, Joshua Kneifel, Kate Beers, Zifeng Lu, Troy Hawkins
The carbon intensity (CI) of producing five different resins – polyethylene terephthalate (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), and polyvinyl chloride (PVC) – in four different international regions –

Standards as Enablers for a Circular Economy

June 30, 2023
Author(s)
KC Morris, Vincenzo Ferrero, Buddhika Hapuwatte, Noah Last, Nehika Mathur
A successful transition to a circular economy (CE) will require global participation, but the path to that transition will follow many unique routes depending on local situations. The transition must have rigorous technical underpinnings and well-conceived

Optimizing Product Life Cycle Systems for Manufacturing in a Circular Economy

April 26, 2023
Author(s)
Buddhika Hapuwatte, Nehika Mathur, Noah Last, Vincenzo Ferrero, Maya Reslan, KC Morris
Global population growth and increasing resource scarcity are necessitating sustainable manufacturing and circular economy (CE) practices. These practices require the decisions made at each product life cycle (PLC) stage consider sustainability and
