A method for real-time burner monitoring and control of a flare system, including analyzing a flare gas and/or flare exhaust gas by one or more analytical techniques and determining the flare gas and/or flare exhaust gas composition. The method may also include an ash particle monitoring system. The method further includes an analytical control unit for real-time adjustment of process conditions.

Apparatus including a receptacle for holding therein organic waste, a first dispenser operative to dispense an oxidizing agent to the organic waste so as to cause an exothermic reaction that results in combustion of the organic waste, and a second dispenser operative to dispense a reducing agent that neutralizes a residual amount of the oxidizing agent that remains after the exothermic reaction.
