HTC method - Integrated Waste System / Recovery of Basic Materials


History
The HTC (Hydrothermal Carbonisation) method was set out by Friedrich Bergius in his doctoral dissertation already in the year 1912. Dr. Friedrich Bergius, who invented the coal hydrogenation method and the cellular hydrolysis method, definitely wanted to find methods in his researches, which should be useful to mankind. But due to historical circumstances (the World War, inflation, collapse of the banks during the world economic crisis) which accompanied his chemical and industrial development efforts, he was not able to accomplish his goals.

Today, closely 100 years after he wrote his scientific applications, an innovative facility is at the mankind's command to safeguard our future in a sustainable manner.

Brief description of the process

With the HTC method, aqueous hydrocarbons are dissolved from coal under moderate pressure and heat influence. This process produces nearly no methane or carbon dioxide. And it can be applied to dry and even to aqueous biomasses also.

The quality of the end product, i.e. of the so-called biochar, depends on the quality of the biomass brought into the process. For organic waste, this process provides a very significant advantage: Organic waste and even sewage sludge, which is a very problem-laden issue, can be brought into the process without any preliminary processings.

The HTC process involves an exothermic reaction which functions without further heat application, once it has been started. The duration of the process is determined by the temperature and pressure conditions.

The negative CO2 budget of this process makes it possible to apply for negative certificates in the global CO2 emissions trade.

Economic benefits and sustainability

  • Free from CO2 emission, nearly no noise or odour emission.
  • Easy handling of the components.
  • No additional energy input. No need to pre-dessicate biomass.
  • No pre-selection or pre-separation processes of the biomass is needed.
  • Without any problems waste materials from the bio-waste containers can be used in this process.
  • As additionional waste, also sewage sludge can be brought into the process.
  • The HTC method has been giving proof of its functional efficiency now for roughly one hundred years and it has been improved constantly during this time.
  • Low investment costs.
  • Low maintenance costs.
