Complex Value Optimisation for Resource Recovery from Waste
University of Leeds.
CVORR is a novel approach that combines scientific and engineering methods with a socio-political narrative grounded in the systems of provision (sop) approach and seeks to assess how value is created, destroyed and distributed in resource recovery from waste (RRfW) systems.
In CVORR ‘value’ has a wide meaning, referring to measurable benefits (creation of positive value) and impacts (creation of negative value, or loss of value) in the environmental, economic, social and technical domains. Considering all these domains – and potentially more e.g. governance – in the evaluation of interventions, allows for a whole-system assessment and provides a comprehensive analytical method for calculating and communicating multi-dimensional outputs, essential to support informed decision-making.
Through this novel way of assessing RRfW systems, CVORR can provide guidance as to where successful interventions can be made, and indicate how changes in the political and legal framework can be instrumental in the better management of resources at different levels of the economy, and the promotion of circular economy.
The CVORR project is in collaboration with and supported by (in alphabetical order): ARUP, British Geological Survey (BGS), Chartered Institution of Wastes Management (CIWM), D-Waste, DcW, EMG, Freeland Horticulture Ltd., International Solid Waste Association (ISWA), Knowledge Transfer Network (Environmental Sustainability), Link2Energy, NFU, OECD, PlasticsEurope, Ramboll, Resource Association (RA), Technical University of Vienna (TU Wien), Technical University of Denmark (DTU), WRAP.
