  There are various methods at our disposal to determine the direct expenses of the factors, which influence the state of health – such as inactive lifestyle –, but research studies aimed at comprehensively determining all direct and indirect expenses have not been conducted in Hungary, yet. We desired to remedy this deficiency with our research, which was prepared at the commissioned order and with the support of the Hungarian Society of Sport Science and the Department for Sport of the Ministry of Human Resources of the Hungarian Government. Using the factual data of OEP (National Health Insurance Fund) we determined the annual cost of illnesses, along with the extent of the cost of physical inactivity, (HUF billion), and we prepared an estimate of the possible amount of savings in Hungary (sick-pay, medication costs etc.), the methodology of which we adapted from international research projects, thus the resulting data in the case of Hungary will later be comparable to international data. International examples reveal the savings achievable by increasing physical exercise in a broad range, even though having conducted the research in different ways and time periods. All research projects concur about one thing, namely that the reduction of physical inactivity can result in significant savings. Our results have verified this statement statistically as well.

  In my article, after describing the characteristics of recent wastewater treatment activity, I introduce different traditional and innovative energetic opportunities of the compulsory waste management activities at large-scale operational level, covering national and international examples. Furthermore, the wastewater-based biomethane production and the certain plant’s energy self-sufficiency are highlighted topics as well. In the former case, it is possible to utilize the wastewater-based biomethane as fuel (and even to operate own vehicle fleet), while the second one gives the opportunity for the internal usage of produced electricity and waste heat, which can also result in significant cost-savings. As an additional option, algae-based wastewater post treatment is presented, based on the conditions of a Hungarian wastewater treatment plant, which biogas production efficiency and thus energy self-sufficiency has developed favourably due to the technological improvements. These plants may have a twofold role in the future: they are responsible for the compulsory waste management activity and on the other hand they can serve as excellent raw material mines.
