Anaerobic waste treatment systems
Long time experiences with the design and erection of biogas systems all over the world as well as the research works carried out by the owner of GBU and GBU itself led to the development of an environmental save processing technology for biogenous waste, which uses the energetic potential of biowaste for the production of electricity, thermal energy and organic fertilizers in an optimized way.
GBU has contracted the turn-key installation of such an anaerobic waste treatment system plant in Belgium with a capacity of 200.000 tons per year of organic waste and a total investment of 40 million German Marks.
 
Adsorption chilling machines
GBU is the sole agent of an Japanese manufacturing company of adsorption chilling machines in whole Europe. As the machine is able to produce cold water out of thermal energy in the lower temperature range (>5O°C) a new possibility is offered to economically utilize waste heat from district heat networks, solar systems, cogeneration plants etc.
GBU designs and supplies the machine as well as total energy systems for administration offices, hospitals, hotels and industry. In Germany are already 20 total energy systems designed and supplied by GBU running.
