CONSIDERATIONS OVER A BIOGAS PLANT COMPONENTS

subject

description

This paper starts from the conviction that one of the main environmental problems of today’s society is the continuously increasing production of organic wastes. In many countries, sustainable waste management have become major political priorities in order to reduce pollution and greenhouse gas emissions and to avoid, as much as possible, global climate changes. This problem becomes more and more present in our country too. Production of biogas through anaerobic digestion of animal manure and slurries as well as of a wide range of digestible organic wastes, converts these substrates into renewable energy and offers a natural fertiliser for agriculture. That is why we consider that biogas plants will be more and more used in the future. In this paper we show the different stages which must be operated in a biogas plant and the problems which can be met in each of them.
