The NSF Sustainable Materials and Circular Economy programs support fundamental research that transforms how materials are designed, produced, used, reused, and recovered. These initiatives advance breakthroughs in materials science, chemical processes, engineering systems, data-driven supply-chain modeling, socio-environmental assessment, and circular-economy frameworks. Unlike single-discipline programs, these efforts span multiple NSF directorates—including MPS, ENG, BIO, GEO, CISE, and TIP—reflecting the inherently interdisciplinary nature of sustainability challenges. Projects often unite chemists, materials scientists, engineers, biologists, data scientists, economists, and social scientists to develop next-generation materials and systems with dramatically reduced lifecycle impacts. 

Research topics commonly include bio-based polymers, recyclable or degradable plastics, low-carbon materials, green chemistry routes, high-efficiency manufacturing processes, upcycling technologies, critical-material recovery, sustainable electronics, circular supply-chain modeling, and multi-scale life-cycle analysis. Many proposals integrate experimental and computational approaches, including machine learning for materials discovery, multi-physics simulations, techno-economic analysis, and environmental impact modeling. Because circular-economy innovation requires both technical and societal feasibility, successful projects often incorporate behavioral science, policy analysis, industrial partnerships, and community or regional engagement. 

Eligibility follows standard NSF rules: applicants must be affiliated with an eligible U.S. institution such as a university, nonprofit research organization, or qualified small business. For-profit firms may participate when research contributes to fundamental scientific understanding rather than product development alone. International collaborators may participate through subawards but may not receive direct NSF funds as primary awardees. 

Competitive proposals clearly articulate the scientific novelty of the materials or processes being developed, demonstrate rigorous methods for environmental and economic assessment, and explain how the research contributes to a more sustainable, resilient, and circular materials economy. Broader impacts may include workforce training, public engagement on sustainable consumption, open-access materials databases, K–12 modules, or partnerships with manufacturing or recycling sectors.
