Brownfield redevelopment refers to the process of cleaning up and repurposing previously used industrial or commercial sites that may be contaminated. These sites, known as brownfields, often pose environmental hazards but can be transformed into useful spaces, such as parks, housing, or businesses, through careful planning and remediation efforts. The redevelopment of brownfields can provide numerous benefits, including revitalizing communities, reducing urban sprawl, and improving public health. By addressing environmental concerns and promoting sustainable development, brownfield redevelopment helps to create safer, more vibrant neighborhoods while making efficient use of existing infrastructure.
