In the time of the world’s growing need for multilingualism it is necessary to examine all possibilities for teaching foreign languages in a faster and more efficient manner. Instead of passive users, we need engineers who actively use foreign languages. CLIL is an approach that insists on economization of time needed for foreign language acquisition. It does so by integrating a foreign language instruction into a non-linguistic subject matter, which increases students’ interest and motivation. The paper investigates English language speaking skills in an engineering CLIL classroom.

The process of composting of biowaste, while ensuring the necessary conditions and depending on the composition of composted material can be carried out in natural conditions. If we want to influence the speed and stability of the process of degradation of organic matter from biowaste, it is necessary that one or more influencing factors control the process so as to provide optimal conditions to maintain the duration of the process. The purpose of the research was used bioreactor which provides a constant temperature outside, the possibility of mixing and wetting the compost mixture without external influence. Controlling certain parameters, ie, the influence on the way to maintain these parameters the optimum leads to a significant acceleration of the process and also to improve the quality of the finished compost with respect to the controlled process more robust to the natural process.

The Plant and Pollution Registry is an important mechanism for strengthening shared responsibility, reducing pollution and promoting sustainable development. Once established, the plant and pollution register will be made available to the public and any person with a legal interest may request access to the register and issue a copy of the registry data. The register shall contain the following information: name and address of operator and location of facility and plant, short description of activities and technological process, relevant information regarding emissions, hazardous substances present at the facility and plant, waste production and use of resources and energy, related data license, changes, etc. and information on controls, relevant results and actions taken. The main purpose and scope of the Registry is to improve public access to environmental information in the Zenica-Doboj Canton and also to contribute to the establishment of a comprehensive national register of pollutant emissions into the air for all zones and agglomerations in the Federation of BiH.
