Energy efficiency

Both at national and international level the focus is not only on the production of energy from alternative sources, but also on saving energy. All consumers – industry and public administration, but also private households – can and must deliver their contribution.

In the private sector, this means:

  • Use energy-saving devices
  • Energy-efficient buildings
  • Energy-Efficient Building Rehabilitation: Insulation of building exteriors (wall, window)
  • Efficiency in the use of energy (thermostatic valves, heat meters)

In the public sector additionally:

  • Efficient energy production
  • Heat recovery and
  • Energy Management

For the industry – particularly manufacturing companies – in addition to the above it also means energy efficiency:

  • Optimization and consumption control of industrial plants and equipments (e.g. electrical drives)
  • Energy Management e.g. for avoiding peak consumption

To all areas the principle applies that people have to be held responsible for the use of the increasingly scarce and valuable resource “energy”.

Erneuerbare Energie

TTM currently focuses on four key areas of energy production from sustainable and renewable energy sources:


In wind parks with several wind turbines electrical energy is generated, provided there are good wind conditions.


Solar cells convert sunlight directly into electrical energy (photovoltaic). Alternatively, water can be heated through heat exchangers (solar thermal).


In a biomass power plant waste wood and residual wood from forestry is burned. The heat generated by the biomass plant is fully used for heating purposes. Alternatively, as an intermediate step, electricity is generated from steam – the residual heat will be used again for heating or drying.


In biogas plants agricultural and industrial organic fractions are fermented in large containers (fermenter). In this process a large amount of methanegas (biogas) is produced that will be burned in a gas burner/engine. The engine drives a generator, which produces electrical energy; the cooling water is used for example for heating or drying.

Waste-Management, lokale Stoffkreisläufe

For energy production biogas plants and biomass power plants use waste materials from local or regional sources as primary energy resources. Therefore the supply chain of raw material has a great importance. Transportation of waste over long distances (like in the case of crude oil or natural gas) should be avoided due to the massive emission of CO2 during transportation.

The collecting, bundling and sorting of waste, transportation to the “right” customers ensures the creation of efficient local material flow. Such local cycles are essential to ensure that regions come closer to the target “zero CO2 emission”
