I couldn't find any reference in openLCA manuals about how this process of modelling should be done. Flows and ow properties form the basis for building openLCA models and performing the calculations. I need to build a process that represent the Incineratotion of Plastic waste and that consider the energy and heat produced from this incineration. As far as I know, if I want to analice the whole process of electricity production it is needed to create a model that combines the three processes and after analice it within the chosen Impact Assesment method. 4 Building the openLCA model 4.1 Distinguishing ows and processes in openLCA Before you begin to build your model, here is a small clari cation on the di erence be-tween ows and processes in openLCA. Hello everybody,I am using OpenLCA 1.10 and Database: Ecoinvent 3.5 cut-off. Furthermore all of the heat generated is used also by the digester. Some of the electricity generated is used by the system. In the anaerobic digestion system I am modelling, biogas is used to generate electricity.

I am wondering how to model parasitic energy demand in openLCA. Similar scenarios apear for other power production technologies. Modelling parasitic energy demand +1 vote. You will notice that, ows for electricity from Biomass already exist for the North American region. commented by h.mhosseini ( 130 points) Thanks Dear Ciroth for your reply, Actually I want to model a coal power plant with its upstream processes and change its efficiency to explore the effects of changing. In addition, the energy and mass balances performed during an LCA are the starting point. Similarly, to create a product system for electricity from biomass, click on Flows and search for Electricity, Biomass, at plant' under the utilities tab. You can of course model a coal power plant (there are already exisiting datasets, in several databases), with unit processes. For example for wind power the information I want to use is divided in 3 different process datasets: one for the power plant (electricity production, wind, 1-3MW turbine, onshore | electricity, high voltage | APOS, S), an other for the wind turbine construction (wind turbine construction, 2MW, onshore | wind turbine, 2MW, onshore | APOS, S) and a last one for the network connection (wind turbine network connection construction, 2MW, onshore | wind turbine network connection, 2MW, onshore | APOS, S). Environmental Sustainability and Process Economics (ESPE) model. I'm using the database : ecoinvent35_apos_lci_20181210. I'm a new user of openLCA and I'm doing a thesis for university in which I need to analyce the environmental impact of various energy technologies from cradle to grave.
