Sustainable Brownfield Remediation
Wednesday 10 November: Sustainable Brownfield Remediation
Some net positive outcomes of remediation projects are already being delivered and communicated through optimum land reuse, pollution prevention and control, and the development & application of sustainable remediation technologies and practices. However, there is potential to do much more, and ensure brownfield regeneration contributes significantly to sustainability goals. These sessions will explore how the industry can step up to the next level; embracing tools to assess, quantify, and demonstrate the impact of brownfield remediation and development in reducing carbon, maximising the benefits of soil, enhancing biodiversity, and adding social value.

SURE, a Digitised Sustainability Assessment Tool for Remediation Option Selection and its Application to Brownfield Site Development
SURE is a fully digitised tool for selecting the most sustainable option for soil and groundwater remediation, which is being made publicly available to all remediation practitioners. It enables the context of the project to be framed, indicators to be drawn from the updated SuRF UK listing, and the assessment to be conducted in a transparent manner with appropriate stakeholder input. The digital output not only provides graphical representation of performance in terms of indicator categories and domains of sustainability, but also enables a comparison of options in terms of their relative contribution to United Nations Sustainable Development Goals (UN SDGs). Application of SURE will be exemplified by reference to a Brownfield Case Study.
10:05
Demonstrating the Sustainability of a Project as part of a Remedial Strategy
A case study presentation outlining how sustainability considerations were built into decommissioning, remediation and flood mitigation works for a major regeneration project at an early stage.
10:30
Assessing the Impact of Climate Change on the Design & Effective Implementation of Remediation Strategies
-
Exploring the consequences increased rainfall, strong winds and prolonged dry spells could have on the effectiveness of certain remediation strategies (eg monitored natural attenuation; capping; excavation and disposal)
-
Incorporating future climate change projections into remediation options appraisal and assessing the impact of this on the selection of a remediation strategy
-
Designing resilient and sustainable long-term remediation solutions to accommodate future changes in environmental and site conditions as a result of climate change
-
what impact will this have on currently used techniques?
-
revisiting current or previously remediated sites to ensure they are climate future-proofed
-
Dr Paul Nathanail, Technical Director Contamination Assessment and Remediation, GHD
Paul is a member of CIRIA’s climate change and contaminated land interest group exploring how extreme weather events will influence remediation practices.

Innovative Remediation Solutions
This session will include case-study presentations offering practical techniques and technologies for remediating different contaminants, including low-carbon and more sustainable solutions
Integration of Nanoremediation and Electrokinetic Techniques to Create New Opportunities for Enhanced In Situ Bioremediation for Contaminated Land Remediation (EiCLaR H2020 project)
14:25
Carbon Sequestration to Stabilise Legacy Chemical Waste and Capture Local CO2 Emissions
Alkaline waste materials can pose significant health, environmental and geotechnical constraints for site redevelopment; however, they can also offer opportunities. This presentation documents the development and pilot trial application of in-situ carbon sequestration to provide long-term stabilisation of legacy alkaline chemical waste in the UK.
David Granger, Technical Director, AECOM
This project was the winner of the 2021 Brownfield Award: Best Scientific/Technical/Digital Advance or Innovation

Case Study: Exploring the Assessment and Sustainable Remediation of London Gasworks for Brownfield Redevelopment
This presentation will discuss a number of gasworks remediation projects across London, highlighting the various challenges faced to the delivery of brownfield redevelopment and remediation, differing priorities across the sites, and how sustainable remediation has been scoped and planned.
