Benefits

  • Technique can be used to detect and cleanse pollutants

Government Backing

  • Danish company Aresa Biodetection
  • Academy of Scientific Research and Technology
  • UN

Risks

  • Limited use
  • Oversensitivity
  • React to other munition

About it

  • Modified version of thale cress, tobacco plant rose periwinkle or sugar beet
  • Functional in 3-5 weeks

How it works

  • Uses gene called anthocyanin to produce a red pigment
  • Indicates landmine, corrodes the cast-iron body with iron-loving bacteria, and neutralizes it by releasing the gas of the degrading TNT
  • Roots of the plants used have nitrogen absorbing enzymes

Issues

  • Unknown environmental effects of introducing a new variation of plant to ecosystem
  • Relatively cheap to produce
  • Even with this new technology landmines are planted 25x faster than they are cleared
