Geobiotechnological solutions to anthropogenic disturbances : a Caribbean perspective /
This book uses a problem-and-solution approach to environmental remediation in mining, including the environmentally sustainable utilization of waste materials from the mining industry. It largely comprises articles published in Springer journals, which have been thoroughly revised and extended. The...
