Bamboo Phytoremediation • Introduction • Bamboo has been successful in dealing with the legacy of Acid Mine Drainage (AMD), in India. In particular revegetation of coal mine overburden dumps • Mining companies in SA have shown interest in planting bamboo to assist in land rehabilitation but no firm commitments at this stage. • Bambusa Balcooa, is our clumping, non-indigenous, non-invasive, locally propagated, bamboo species using tissue culture technology. It is ideally suited for phytoremediation and biomass feedstock. • No water permit is required. • If the mine is not yet closed, no EIA is needed and the EMP can be amended. Introduction Growing Bamboo will not... VSS Proposal Investment Benefits The way forward...
Bamboo Phytoremediation • Bamboo plantations • will not... • Grow whilst submerged in water • Convert contaminated water to produce potable/drinkable water But Bamboo plantations can... • Use Acid Mine Water (for irrigation purposes) • Adsorb unwanted heavy metals (e.g. Zinc, Chrome, Iron, Lead) • Adsorb unwanted toxic substances (e.g. Mercury, Uranium) • Reduce radio-activity levels • Increase pH levels • Tolerate acidic soil Introduction Bamboo plantations will not... VSS Proposal Investment Benefits The way forward...
Bamboo Phytoremediation • VSS Proposal • Secure Mine Land (long-term lease – zero cost) • Organise Preferential Finance (DBSA, IDC, 3rd Parties) • Establish Bamboo Plantations (life expectancy 20 years min.) • Build Bamboo Bio-Coal Plant (beneficiate bamboo raw material 5th year onwards) • Harvest Bamboo Crop (from 4th year onwards) • VSS to manage project • Legal entity to be formed to protect individual interests of all parties and address ownership and % share distribution Introduction Bamboo plantations will not... VSS Proposal Investment Benefits The way forward...
Bamboo Phytoremediation • Investment • Mining Company (Land & Rehabilitation Fee, Performance Based) • Investors (Total – R 74,2m) Bamboo Plantation – R 23,8m (400ha – 237,600 bamboo plants, yield 60,000 mt/y) Bio-Coal Plant – R 50,4m (30,000 mt/y) • Community Part ownership within legal entity and allocation of portion of crop for downstream business activities (using raw bamboo material) • VSS Project Developer (Part ownership within legal entity, performance based bonuses/penalties within SLA) Introduction Bamboo plantations will not... VSS Proposal Investment Benefits The way forward...
Bamboo Phytoremediation • Benefits • Mining Company (Mine Land Rehabilitation & full mine closure) • Investors (DBSA funds back with zero interest – Bonus! , IDC funds repaid with 8% interest! , 3rd parties repaid with market-related interest) • Community (60 permanent & 20 casual plantation jobs & 25 permanent bio-coal production plant jobs created in rural area) • VSS Project Developer (Project management fees & performnace based bonuses/ penalties rewarding our initiative and on-going interest in project's success) Introduction Bamboo plantations will not... VSS Proposal Investment Benefits The way forward...
Bamboo Phytoremediation • The way forward... • VSS's main challenge is to : • Secure finance through government aligned lending institutions such as : • National Treasury's Jobs Fund (administered by DBSA) • IDC who have already indicated their interest in similar projects (in particular bamboo!) • Get as many mining companies on board as soon as possible, by demonstrating the efficacy of Bamboo Phytoremediation as a holistic, long-term solution for rehabilitation of contaminated soil and much, much more! Introduction Bamboo plantations will not... VSS Proposal Investment Benefits The way forward...
