BIOENERGY FOR MINES
RECLAIM TO REMEDIATE
Returning a disturbed environment to a socially, economically and environmentally acceptable condition which is similar to its original condition or better.
Implementing processes to return the land to a sustainable useable condition.
Mine impacted land has very little or no economic value as it is not suitable for food or feed crops and it negatively impacts on the environment as follows;
Has the potential for legacy costs through future latent & residual impacts
Selectra’s strategy is RECLAIM to REMEDIATE in the belief that an effective reclamation programme will lead to remediation.
Our sustainable solution is to cultivate energy crops on impacted land. The application of Biocomplex, a completely natural bio-activator, promotes bioremediation which is aided by the energy crops taking up contaminants and heavy metals through a process call phytoremediation. These contaminants and heavy metals are deposited in the H2E Anaerobic Digester as a concentrated mineral sludge for further processing or disposal. High quality biogas is a by-product of the process and this energy source is deployed in the mine processing plant to displace higher cost fuels.
Key elements of Selectra’s approach are;
EKO GEA BIOLOGICAL ACTIVATION
Biological activation of soils and plants is a critical step towards establishing the plantation. This is achieved by application of Biocomplex, a completely natural bio-activator that promotes bioremediation.
What It Is:
Oligosaccharides, the essential sugars that stimulate microbial activity, and a complete range of pro-biotic compounds, trace elements and micro-nutrients, that are chelated, colloidal, and optimally balanced for ready uptake by the plant.
How It Works:
EKO GEA's proprietary treatment:
Root Concentrate: Provides unique protection and growth stimulation during early growth.
Foliar Spray: A general treatment to stimulate plant growth in developing plants.
Crops for mine impacted areas are selected for specific traits, which suit the site where they are to be utilised, and range from high input [water and fertiliser], high yield crops to low input, lower yield crops.
The goal is to select energy crops that can be cultivated in the harsh conditions associated with impacted land with key requirements of scalability, reliability, and consistency that results in inexpensive feedstock supply. This is achieved by crop selection using the following guiding principles;
The Selectra Process is all about organisation of the biophysical aspects (the overlap of physical, chemical and biological aspects of the local environment) in the development of the Agronomic Strategy.
Selectra retains the services of DR Johan Van Tol of Hydropedological Solutions as lead consultant.
