Former industrial sites in rural and urban areas can present significant environmental and economic challenges, but Delta has experience working with nonprofit, government and industry partners to remediate vacant industrial sites by planting tree farms. Specific trees, such as poplars, provide environmental benefits, preventing soil erosion, removing contaminants and sequestering carbon, and they can create local economic opportunities by remediating contaminated sites for redevelopment and providing an affordable, local and sustainable source of wood for local manufacturers.
