(Hyper)trendy Production of Heat for Detached Houses. Value for Money
Summary: A heating system that also includes hot water preparation is an inseparable part of detached houses (residential houses). The choice of the system should be very carefully considered before the construction of the building in question. The choice of the system influences, positively or negatively, thermal comfort in the house, the convenience of living in the house, and also the total costs of installing and operating the heating system, for a long time.
One of the (hyper)trendy systems that are said to improve the energy efficiency of houses (buildings), save primary energy and obtain energy "completely for free" from the sun is the photovoltaic "all in one" system.
What is the economics of operating this system? What value for money will the owner of the system receive? Will owners of such systems obtain electric energy really "for free" as some suppliers of these systems tend to suggest?
Methane from Municipal Solid Waste Containing Aluminium
Petr Buryan, Tomáš Hlinčík
Summary: The contribution discusses the recovery of methane from municipal solid waste containing aluminium. The study brings the latest results of research into reactions of solid waste obtained from various packaging materials containing aluminium under the thermodynamic conditions prevailing in landfills. It then describes methanogenesis (or biomethanation) in biogenic processes. The monitored waste has helped to prove that the use of certain aluminiumcontaining waste could help to produce approximately 3.2 million m3 of methane in the Czech Republic per year, which could then be used for consumption in 1,270 detached houses.
