  • 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

  • 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)

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)

  • 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)

7
  • 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

Introduction Bamboo plantations will not... VSS
Proposal Investment Benefits The way forward...
