Research area

Dr Castillo Castillo specialises in Energy Policy and techno-economic analysis of waste to energy and materials technology. He has worked as a consultant in the area of innovation policy relevant to hydrogen and fuel cells, where he co-authored the UK fuel cells development anddeployment roadmap. At the Centre for Environmental Policy he has worked in two main areas. He has worked as lead-researcher in biological and thermal waste treatment techniques. He is member of the Industrial Symbiosis Platform of the European Climate Knowledge and Innovation Community, which preceeded the introduction of the Sustainable Production Systems theme. Since 2014 he has led Activity Line 1 Analysis and enablement of CO2 reuse value chains of the EnCO2re programme.  In 2016 he was part of the Steering Committee of the European Sustainable Chemicals Support Service. He is involved in developing methods for deployment of waste to energy and materials in industrialised and low-income countries, notably anaerobic digestion, where they can assist sanitation, disease prevention, fertiliser production and improvement of livelihoods.

Global urbanisation has increased the amount of resources that are irreversibly extracted from natural cycles without recovery as energy or materials. Dr. Castillo's research formalises the synergy between the traditionally unconnected fields of Waste Management, Resource Use Efficiency, Industrial Ecology and Energy Policy. Main activities are in the context of emerging regulatory, commercial and scientific developments combined to build a technology mix that generates benefits within both sectors. His area of work encompasses a techno-economic and life-cycle-assessment framework with scenario development. Research questions aim to tackle the potential to reduce landfill tax, penalties and the creation of new market opportunities combining objectives of the two fields.
