Nutrient recovery through source separation
During her 20-year Argonne appointment, M. Cristina Negri (Agronomist, University of Milan, Italy, 1981) conducted and directed laboratory to full scale multidisciplinary projects developing technologies for environmental remediation and stewardship, including soil and water remediation. She has applied sustainable technologies to address issues of brownfield remediation and more recently to non-point source pollution management. Her interests are in systems approaches where industrial ecology concepts are applied to water and land management, both in agricultural and urban contexts.
Prior to Argonne, M.C. Negri worked 10 years in private industry in Italy as R&D manager and liaison with universities and other Italian national research organizations. Research focused on developing methods for the sustainable, beneficial reuse of industrial and urban waste and for pollution mitigation in agriculture. This work was in support of a state-of-the-art, innovative, large facility for the treatment and beneficial recovery of waste products in agriculture. She also served as the Convener of a CEN (the European Standardization Organization) Working Group, leading experts from European Union Nations towards the creation of European environmental standards for agricultural commodities.
