EBNet Working Group: Process Integration and Sustainability Assessment

Aim: To create awareness on Theme 3 of EBNet – Technology Interfaces.

Technology Interfaces cut across the other two themes of the EBNet: Pollutants and Media; and Biosciences & Engineering. The main driver for this theme is to translate the outcomes of environmental biotechnology into societal benefits. For this, systematic appraisal at a whole process flowsheet level as well as supply chain system level is necessary using a whole range of sustainability criteria.

Even though a process may look promising at a laboratory scale, its scale-up could be challenging, so could be process integration and sustainable development in reality. Many considerations such as technical, environmental, social and economic have to be taken into account and analysed using tools and methodologies, which are sometimes more standardized and at other times more fundamental. Process integration or process systems engineering tools stem from the idea of the highest efficiency flowsheet development with the maximum in-process recovery of energy and material resources. The integrated process flowsheet is then inherently more economically viable than otherwise, where the majority of the cost may be incurred from external heating, cooling, electricity and reagent supplies.

Following the process integration principles, fundamental reactions through separation to utility system designs and optimisation are conducted. There are fundamental tools to help scale up and process integration to create a design with the highest economic margin and resource efficiency. In addition, sustainability assessment is necessary through life cycle assessment (ISO14040-44) and social responsibility analysis (ISO26000) to ensure that across the scales (temporal: life cycle; spatial: supply chain) the process is sustainable.

The working group on this very relevant and unique theme will be necessary to create awareness on the tools and methodologies to optimise the unit process through to whole systems amongst the EBNet community. Applying these tools and methodologies will help researchers and practitioners convince industrial uptake of their technologies and help policy-makers through evidence-based systematic decision analysis.

WG  activities

An introduction to Life Cycle Assessment (LCA) course, 26–27 November 2024, The Guildhall, St Martins Courtyard, Coney St, York YO1 9QL. BBNet, HVB, EBNet and the Supergen Bioenergy Hub jointly offer this ‘An Introduction to Life Cycle Assessment (LCA) Methodology’ Course. LCA is a rapidly evolving tool used to determine impacts of products or systems over a range of environmental and resource issues. Applying this method of assessment is complex and difficult, and translating the theory into a credible, transparent and applicable practice can be challenging. The two day in-person course will provide an introduction to LCA methodology (following ISO 14040 and ISO 14044 standards) and how to apply LCA in your bioeconomy based setting. Delivered by colleagues from University College London, the course took place on 26 and 27 November in York, UK. 

Training Course: LCA in practice. – 28-30 October 2024 9-17:00, Wates Treetops, University of Surrey, in person.
This course aimed to develop skills in the LCA methodology by providing in-depth training on LCA methodology, and practical experience of doing LCAs in practice. Learning outcomes: Be able to deploy resources required to do an LCA study in practice; Identify the key benefits and challenges of the application of LCA for a range of purposes; Develop practical skills in LCA problem-solving; Be able to critically evaluate the quality of an LCA study done by others.

Life Cycle Analysis (LCA) Workshop: GWP standards, carbon offsetting schemes, carbon footprint calculator and offsetting methodologies and techno-economic analysis (TEA) – 30 April 2024, 10-16:00, Chilworth Science Park, Southampton, in person.

Life Cycle Assessment (LCA) for the EBNet Industrial AD Community – Goal and Scope – 30 October 2023, 10.00 – 16.00, University of Surrey, in person.
