Critical Mineral Recovery from Waste Materials  

​Critical Mineral Recovery from Waste Materials                        

11 June at 4-5pm, Online Event


Critical minerals are key to meet the demands of a shift towards renewable energy, such as solar, wind, hydrogen and battery power. Increased supply of minerals such as lithium, nickel and cobalt for battery cathodes; rare earth elements for electric vehicle and wind turbine motors; and gallium, germanium, indium and tellurium for photovoltaics, is needed. The energy transition will result in a shift from hydrocarbon based energy generation to metals and minerals as the raw materials of green energy technologies.

This webinar will focus on critical mineral recovery from waste materials across the UK and the USA. Waste streams such as pulverized fuel ash (UK specific), coal combustion residuals (USA specific), ochre accumulated from mine waters (UK specific) and acid mine drainage precipitates (USA specific) will be highlighted through case studies. The current policy landscape, as well as current incentives, will also be discussed.

​Part 2A investigation of Vapour Intrusion from Chlorinated Solvents                                  

12 March at 1-2pm, Webinar


This webinar is a case study presentation, which covers a Part 2A investigation into contamination of the soils and groundwater at a former dry-cleaners in Ross-on-Wye. The case study won Best Project Preparatory Work at the 2023 Brownfield Awards.

The predominant pollutant pathway was associated with vapours from the chlorinated solvent plume which had migrated off site beneath existing residential buildings. The investigation comprised multi-level boreholes, vapour wells, surface water sampling and in-house vapour sampling, both in-house and sub slab. The investigation needed to account for fractured bedrock, potential vapour flow through the unsaturated zone, topographic falls across the wider area, consideration of preferential pathways (sewers) and background solvent concentrations.

It also included a detailed communication strategy with emphasis on the off-site residents to enable entry to their properties.

​SURE By Ramboll: An Innovative Digital Tool for Embedding Sustainability in Remediation Options Appraisals                                      

8 February at 1-2pm, Online Expert Talk


In sustainable remediation the net benefits on human health are greater than the impacts of the remediation work on the environment, society, and economy. Selection of a sustainable remediation strategy is achieved by using a balanced decision-making process.

'SURE by Ramboll' is a free-to-use, online platform that helps to assess the sustainability of remedial options. The platform allows users to assess and compare the sustainability of multiple options against user-assigned sustainability criteria. The assessment results can then be shared with clients and stakeholders within the platform to request their review and comments. Once the assessment is completed, a custom PDF report of the whole assessment can be created and shared.

In this Expert Talk, Peter will provide an introduction to SURE, and outline how the tool can be used and the key functions, using a case study example which won the ESG Innovation Award at Environment Analyst's 2023 Sustainability Consulting Awards.

​Land-Based Approach to Natural Capital Asset Management: Building Towards a Better Management of Natural Resources                                   

18 January at 1-2pm, Online Expert Talk


The Environment Agency recognises that the full value of remediation in terms of the economic, social and environmental benefits is not well understood, and it is often viewed as a cost burden or liability. As such the total benefits of remediation are not fully understood or utilised in decision making, resulting in sites remaining derelict for years and opportunities to optimise value from public and private investment are missed.

In this Expert Talk, Yolande Macklin presented current research conducted for the Environment Agency on the development of a novel natural capital approach to evaluate the sustainability benefits from remediating and redeveloping contaminated brownfield sites. This proof-of-concept co-designed research is helping the Environment Agency develop new methods to measure and communicate the social, economic and environmental value of remediating contaminated sites to optimise the planning, funding and delivery of its land contamination functions.

​Impacts of Climate Change on Brownfield Regeneration – Risks and Opportunities                                

27 September at 13:00-14:30 BST, Online panel discussion


An increasing challenge for successfully regenerating Brownfield Land in the UK is shifting weather patterns associated with Climate Change. The past five years have seen an increasing trend of hotter, drier summers and milder wetter winters, interspersed with periods of abnormal (often wetter) weather. The increased frequency and intensity of wet weather creates significant challenges for managing earthworks on brownfield sites including damage to soil structure, contaminated (and uncontaminated) silt run-off and increased fluctuations in groundwater levels. 

Post remediation, brownfield developments are also placing significant additional pressure on our fragile sewage and river systems due to the practice of diverting rainfall away from groundwater infiltration systems (e.g. soakaways) and into the sewage and river systems. 

These changes have wide ranging implications for developers, consultants and contractors alike – from the risk assessment and design stages through to site implementation (to programme / specification) and the potential need for ‘future-proofing’ remediation & earthworks projects in tandem with development levels and drainage for flood protection. 

Whilst there are clear risks, are there also opportunities for the brownfield regeneration industry to help deliver a more sustainable, circular economy – this topic will be explored with our expert panel, held with Brownfield & Regeneration Network premium partner Soilfix

Discussion Topics:

  • Extremes of rainfall and impacts upon the site, groundwater & river levels – what are the impacts on project / contract delivery, sustainable drainage solutions, flood risk, sewer discharge considerations?
  • Risk Assessments – what are the implications of climate change on ‘future-proofing’ and also potentially ‘looking back’?  Are we seeing projects where previous risk-based remediation or flood risk levels are no longer valid?
  • Carbon outputs of certain remediation & earthworks techniques – will we reach a point where certain techniques or approaches become redundant?

​Stabilisation and Solidification of Soils – Practical Implementation to Manage Geotechnical and/or Contamination Risks                                         

16 August at 13:00 BST, Webinar


Stabilisation and Solidification has become widely applied across the UK and is no longer considered to be an emerging remediation or soil improvement technique, having been applied to a wide variety of contaminants and environmental settings.  However to ensure a successful project outcome, contractors and consultants alike need to carefully consider the most appropriate technique (or combination of techniques) to adopt, and carry out site specific design / treatability studies before implementing the S/S project at the full scale.

In this webinar Brownfield & Regeneration Network Premium Partner and Remediation specialist Soilfix provided a variety of project examples to demonstrate how this technique can be successfully applied to solve a variety of contamination and geotechnical challenges on sites.

​Achieving Nutrient Neutrality in Brownfield Development 

19 October, Online webinar


Nutrient neutrality is a means of ensuring that a development plan or project does not add to existing nutrient burdens within a catchment or result in a net increase in nutrients received by sensitive habitats downstream. However, this has considerable implications for the planning and development of brownfield sites where it is often harder to provide the necessary mitigation onsite due to spatial constraints or the density of the development. 

In this webinar Simon and Wendy will outline the background to the nutrient neutrality issue, talk about the process of assessment and implications for inclusion of mitigation on site (with specific focus on brownfield sites), with discussion from the Local Planning Authority point of view, explanation of more strategic options, and how things are likely to develop in the next couple of years.
