Abstract
Anthropogenic activities have caused widespread land contamination, resulting in the degradation and loss of productive land, deterioration of ecological systems, and detrimental human health effects. To provide land critical for future sustainable development, remediation and redevelopment of the estimated 5 million global brownfield sites is thus needed. In this Review, we outline sustainable remediation strategies available for the cleanup of contaminated soil and groundwater at brownfield sites. Conventional remediation strategies, such as dig & haul and pump & treat, ignore externalities including secondary environmental burden and socioeconomic impacts such that their life cycle detrimental impact can exceed their benefit. However, a range of sustainable remediation technologies offer opportunities for urban revitalization, including sustainable immobilization, low-impact bioremediation, novel in-situ chemical treatment, and innovative passive barriers. These approaches can substantially reduce life cycle environmental footprints, increase the longevity of functional materials, alleviate potential toxic by-products, and maximize overall net benefits. Moreover, the integration of remediation and redevelopment through deployment of nature-based solutions and sustainable energy systems could render substantial social and economic benefits. While sustainable remediation will shape brownfield development for years to come, ethics and equality are almost never considered in assessment tools, and long-term resilience needs to be addressed.
