Webinar held 12th January 2015

The webinar was attended by around 30 academics and industrialists, and supported by facilitators from the University of Bath and Granta.

The webinar was introduced by Manuelle Clavel from Granta, followed by an introduction to the G.EN.ESI project and the structure of the webinar from Lucie Domingo of the University of Bath.  This was followed by a demonstration of the software tools in the G.EN.ESI platform, and the webinar concluded with a question and answer session led by Helen Cornwell of the University of Bath.

Summary of questions raised

The first question concerned the Eco Audit energy and water use indicators and whether these only include direct use, or indirect use also.  Luca Petruccelli of Granta answered.

The water usage indicator includes both direct and indirect water. The indicator is representative of water required to operate the processing equipment and all other water requirements of the facility (such as: washing, dust control, cooling, etc.). Note this does not include the recirculating water of cooling systems and the non-polluted water remitted in the same catchment.The current values in Eco Audit are representative of materials production only.  Recent improvements have been made to evaluate the water use of primary processes that will be updated in the future release of Granta’s reference database, MaterialUniverse.

 

A further question related to the environmental data used within the software tools, and the quality and source of this data.  Patrizia Buttol answered on behalf of ENEA.

The main source of data within eVerdEE is the eLCD (Environmental Life Cycle Data System) that we have extended to fulfil the simplification requirements of eVerdEE. In addition, data produced in ENEA LCA studies (within G.EN.ESI and other projects) have been used to populate the database. The approach requires the involvement of stakeholders, sector-specific technical knowledge and peer review by experts. Further development of the database is expected.  Within eVerdEE, when the user selects data from the database, information on data quality can be obtained by clicking on the icon ‘i’ near the dropdown menu. The information includes a technical description (short description of the process), advice on how to use the data, recommendations on applicability, known limitations etc. and a statement that indicates strengths and/or weaknesses in data quality or difficulties in data use or interpretation.

Luca Petruccelli of Granta also addressed this question.

Granta assesses and develops environmental data by means of internal estimations based on scientific articles, data from producers, publicly available data such as EPDs from manufacturer associations (e.g. Plastics Europe, European Aluminium Association, World Steel Association etc.) and internationally recognised LCA databases such as Ecoinvent and ELCD.  The environmental data in MaterialUniverse also includes data traceability allowing users to trace the main data sources used for the elaboration of impact indicators.  The data quality is assured by internal procedures which evaluate data sources.  Regular reviews of the data are performed in order to keep the database up-to-date.  In addition, specific notes about the data are provided (boundaries of the analysis, limitations and general sources of data) and scientific notes about the approach to data estimation and calculations.

Thank you to everyone who took part in the webinar.  Particular thanks are due to our panel of experts who answered questions at the end of the webinar, and to Granta for kindly hosting the webinar.
