A Penn State workshop of 150 experts found that social science expertise, not just mining and engineering talent, is a key missing piece in building a resilient US critical minerals supply chain.
At a glance
- A Penn State workshop of about 150 government, industry and academic participants identified social science expertise as a key hidden gap in building the US critical minerals workforce.
- Beia Spiller of Resources for the Future said social scientists help build the community trust needed for mineral projects to move forward, alongside their role in shaping durable policy.
- More than 60 minerals are currently federally designated as critical in the United States.
- Less than 5% of materials in US waste streams are currently recycled domestically.
What happened
A three-day critical minerals and materials workshop hosted by Penn State in August 2026, bringing together roughly 150 participants from academia, industry and government agencies, identified social science expertise as one of the field's most overlooked workforce gaps. Beia Spiller, director of the Transportation Program at Resources for the Future, told the workshop that social scientists help "shape durable minerals policy and build the community trust" that mineral projects need to actually get built -- work she and other speakers characterized as a hidden but essential part of the supply chain, alongside more visible gaps in public-sector capacity and global technical talent. The workshop, convened by Penn State Materials Research Institute director Joshua Robinson, also featured Jeremy Mehta, chief of staff for critical minerals, materials and manufacturing at the US Department of Energy, and researchers from Pacific Northwest National Laboratory (PNNL), Northwestern University, and the DOE's Critical Materials Innovation Hub at Ames Laboratory. Participants noted that more than 60 minerals are federally designated as critical, while less than 5% of materials in US waste streams are currently recycled domestically -- a gap PNNL is targeting with a newly developed, patent-pending process that uses supercritical carbon dioxide to extract critical minerals from existing mines while permanently sequestering carbon in the process.
The details
The critical minerals conversation in the US has mostly been framed around hard technical constraints -- not enough mines, not enough refining capacity, not enough geologists and metallurgists. What the Penn State workshop's framing adds is a less obvious bottleneck: even where a mineral deposit and the engineering know-how to extract it both exist, a project can still stall without the social science work needed to earn community trust and navigate the policy process around it. Beia Spiller's point -- that social scientists "shape durable minerals policy and build the community trust" projects need -- reframes workforce planning as something broader than training more mining engineers.
That framing matters because of where a large share of US critical mineral reserves happen to sit. Domestic deposits sit disproportionately near Native American reservations, according to separate research from the same policy circles, which means community engagement isn't a nice-to-have add-on to a mining project -- it's frequently the determining factor in whether a project can proceed at all, regardless of how technically sound the extraction plan is. A workforce pipeline that produces plenty of mining engineers but no one trained to do that community and policy work would still leave projects stuck.
The recycling statistic cited at the workshop -- less than 5% of materials in US waste streams currently recycled domestically, against more than 60 federally designated critical minerals -- points to a second, related gap: even minerals the US has already extracted and used once are mostly not being recovered and reused. PNNL's supercritical CO2 extraction process, which pulls critical minerals from existing mine sites while permanently sequestering carbon, is one technical response aimed at that gap, effectively turning already-disturbed mine land into a secondary source rather than requiring entirely new extraction sites. But a technology like that still needs the same workforce -- including the social science and policy expertise the workshop highlighted -- to actually get permitted, financed and built at scale.
Why it matters
For a country trying to build a critical minerals supply chain largely from scratch, workforce planning that only counts engineers and geologists risks missing the actual constraint. If community trust and policy navigation are genuinely as important to getting projects built as the technical extraction work, then US critical minerals strategy -- and by extension, how quickly domestic supply can reduce reliance on countries like China that currently dominate refining -- depends as much on training social scientists and policy specialists as on training mining engineers.
Our read
Outlook: neutral. This is a workforce and policy discussion about long-term critical minerals supply chain capacity, not a near-term supply or demand event, so it carries no direct near-term price implication for any specific critical mineral.
What to watch
- Progress and commercialization timeline for PNNL's supercritical CO2 critical minerals extraction process
- Any new federal workforce development funding specifically targeting social science or community-engagement roles in the minerals sector
- US domestic recycling rate trends for critical minerals over the coming years

Timeline
- 2026-08-01: Penn State hosts a three-day critical minerals and materials workshop with about 150 participants from government, industry and academia.
Supply Drivers
Less than 5% of materials in US waste streams are currently recycled domestically, even as more than 60 minerals are federally designated as critical -- a gap that new technology like PNNL's supercritical CO2 extraction process aims to help close by recovering minerals from existing mine sites.
Government Policies
US Department of Energy officials, including Jeremy Mehta and Burt Thomas of the Office of Advanced Mining and Mineral Production Technologies, participated in the Penn State workshop, reflecting active federal engagement in shaping critical minerals workforce and technology policy.
Geopolitical Risks
Building a durable domestic critical minerals workforce, including social science and community-engagement expertise, is positioned as part of the broader US effort to reduce reliance on countries -- chiefly China -- that currently dominate global critical mineral refining and processing.
What could lift prices
- New technology like PNNL's supercritical CO2 extraction process could unlock additional critical mineral supply from already-disturbed mine sites without new extraction footprints.
- Growing federal and academic attention to workforce gaps, including social science expertise, could accelerate project approvals that have historically stalled on community trust issues.
What could weigh on prices
- A domestic recycling rate below 5% for critical minerals in US waste streams shows how far the country remains from closing its own supply loop, regardless of new mining projects.
Country impact
| Country | Impact | Reason |
|---|---|---|
| United States | Medium | A Penn State-convened workshop identified workforce gaps, including social science expertise, as a constraint on building a domestic critical minerals supply chain. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Critical Minerals Workforce Development | Positive | Growing recognition of social science and policy expertise as essential to the critical minerals workforce could broaden training and hiring pipelines beyond pure technical roles. |
Who gains, who loses
- Universities and workforce training programs: Growing recognition of social science and policy roles in critical minerals could expand funding and enrollment for interdisciplinary programs beyond traditional mining engineering and geology.
Other ways this could play out
- If universities and workforce programs begin explicitly training social scientists and policy specialists for the minerals sector, project approval timelines could shorten meaningfully over the coming years.
- Without addressing the community-trust and policy gap directly, continued technical investment in mining and extraction technology like PNNL's CO2 process could still stall at the permitting and community-engagement stage.
Technical view
