Bioremediation of organic wastes

Wastes, the environment and economics are three clearly interconnected topics. Hence the importance of such an unloved problem as the first.

During my career, I have tried to develop techniques that permit to broaden our scientific knowledge of organic wastes, and to offer the possibility of using them in new, effective, environmentally correct, economically viable, and socially acceptable ways, converting them whenever possible into “resources” as opposed to merely “waste” products.

The research is focused in two lines:

  • Optimisation of parameters for composting process.
  • Compost stability and maturity index.
