Andrea is a Chartered Environmentalist and Engineer who has been at the forefront of circularity in the built environment for 15 years. Specialising in the sustainability of the built environment, with particular expertise in the circular economy and how this applies to materials, structures and buildings. Her work has covered both increasing the use of reclaimed materials and designing to facilitate future reuse. She has vast experience working in both the public and private sector, in an advisory, client and research capacity, and at all scales from industry-wide initiatives, to focussing on cities, projects, organisations and products. As HS2 Sustainability Manager, she developed the project's approach to circularity. Following this, she went on to explore further systemic enablers to circular construction through the EU Horizon 2020-funded CIRCuIT project at ReLondon.
