The Process…The Advetec Way Advetec’s BioThermic Digesters (BTD) is the most advanced solution for processing organic waste. The process uses heat energy to vaporize off the moisture content in the organic solid waste and then fed by extremophyllic bacteria which thrives at high temperature, thus reducing the waste content, 80% upto 95% of the original volume.


The BTD essentially has a series of chambers, depending on the unit capacity, made in the UK to exacting standards in SS 316 L grade and a timer based conveying system, which helps transport the stream from one chamber to the other. The system is fully automated and plc based, with minimum requirement of personnel after the unit has stabilized. The heating requirement and temperature setting of the compartments will be programmed into the plc…then on, the system works automatically, including the dosing of the innoculants and the stimulants, as required by the system.

The BTD uses non-chemical inoculants and stimulants which are blends of naturally occurring plant matter that invigorates the extremophiles and stimulates metabolic process to work more effectively. As the bacteria eat more and more organics they produce heat to a point that it causes the base BTD operating temperature to be in the range of 150 – 200 C, thus reducing the power to heat up the compartments, which is the first phase of the process.
