GHG emission savings - Opis:
- One of the contemporary problems of developed societies is the generation of more and more waste. This waste comes from households but also from agriculture and from various industries. A significant part of the total waste is biological waste, which can be reused. One way to manage waste with this status can be to use it in methane fermentation processes that produces high methane gas. As a result of biogas purification, biomethane is obtained, which can be used as a raw material for the production of electricity and heat, but it also can be used as transport fuel. In the case of use in transport and due to the biological origin of the raw material, this opens the possibility of including methane from biogas in the implementation of National Indicative Targets. To this end, it is necessary to meet a number of requirements. In addition to the quality requirements that apply to the final product, the requirements for sustainable biofuel production should be met. These, in turn, apply to all stages of the biofuel life cycle. a large proportion of these requirements relates to the origin of the raw materials from which the biofuel was obtained and the life cycle requirements for the minimum threshold for reducing greenhouse gas emissions. As part of this study, the biomethane production process was analyzed for GHG emissions, taking into account all stages, from growing/collecting raw materials to producing the finished product (CNG biofuels). For comparison, two models were adopted, i.e. the use of waste raw material (slurry) in a biogas plant or the use of wholesome raw material (maize). By applying the calculation methodology given in Directive 2009/28/EC, the levels of greenhouse gas emission savings for both raw materials were calculated. In addition, a bi-variant calculation was carried out for each raw material, assuming different digestate storage methods. Based on the results obtained, key factors affecting the level of emissivity of the biomethane production process were identified.
