Keystone Environmental, along with its client Canadian National Railway, receives patent approval to support dewatering with an innovative concept: a biodegradable permeable geobag, designed from renewable materials, to replace traditional, labour and energy intensive, filter presses and non-degradable, synthetic dewatering geobags. This innovation allows for the geobag and sludge material to be diverted from landfill disposal and re-directed to a treatment facility for re-use in mine site reclamation.
