Theory of factor experiment (matrix of impact) of greenhouse as a composition system for biogas production and regulation for permissible emissions of harmful materials in atmosphere

  • 1 Faculty of Biotechnical Sciences – University St. Clement Ohridski – Bitola, the Republic of North Macedonia


By applying a complex, exact and scientific approach, was performed the development, calculation and analysis of a complex pilot installation (bioenergetics system consisting of the following elements: greenhouse for early vegetation crops, digester and internal combustion engine powered by biogas). Using the factorial experiment, i.e. applying the matrix of influence, a complete optimization of the internal combustion engine was performed in function of the other elements of the installation. An analysis is also made from the aspect of the positive current EU regulations in the field of air pollution.
