NOMAD gathers partners from China, Greece, the UK, Italy, Romania, Malta and the Netherlands to develop an innovative, small-scale tech solution designed to recover fibre and specific nutrients from digestate for formulation into high performance bio-fertiliser products. It addresses key digestate issues including environmental and health risks, handling, variable composition and the increasing volume being produced. Currently, turning digestate into bio-fertiliser products is not feasible for most small plants due to lack of available, cost-effective equipment, and the expense of achieving end of waste standard PAS110. Building on partners’ previous work, the proposed technology will utilise heat from combustion of waste timber and recovered energy from a collection vehicle to improve energy efficiency while simultaneously addressing regulatory compliance. Specific nutrients will be extracted from the liquid fraction and water recovered for reuse. The remaining sludge will be blended & composted with ash (derived from waste timber combustion) and biochar to produce optimised, nutrient-balanced soil conditioners. The model rests on the solution’s mobility and modularity as one unit could serve multiple plants, tackling digestate from a range of feedstocks with shared costs making it more viable than installing systems at individual plants. Other project activities include stakeholder engagement; field trials across contrasting regions; policy recommendations; a comprehensive impact assessment of the business model; and dissemination of key outputs. The project aims to replace non-renewable mineral fertilisers with low-carbon, organic equivalents; minimise environmental and health risks associated with digestate; create a new, disruptive business model for rural decentralised AD; and achieve a more favourable climate for circular economy development through successful stakeholder engagement.

Urban systems globally experience significant and interlinked societal challenges including pressures on public health and well-being and growing inequalities and social disruption. At the same time, urban systems are particularly vulnerable to impacts of climate change and suffer from degraded or lack of natural ecosystems to help alleviate these impacts. A promising approach to deal with these challenges is to work with nature’s capacity and qualities in a sustainability perspective. Working with nature in urban settings has advantages over other approaches: multi-functionality, multi-benefits and cost-effectiveness. Nature Based Solutions (NBS) are interventions that seek to restore, improve, enhance or conserve natural capital and biodiversity in terms of habitats or ecosystems. Subsequently, these ecosystems provide enhanced multiple ecosystem services that contribute to social and economic benefits, reducing the urban societal challenges. They can help build climate resilience in cities, improve liveability, and in collaboration with other urban priorities contribute to building inclusive communities, closing social equality gaps, while promoting innovative businesses and jobs. The aim of Regreen is to generate evidence for how Nature-based solutions (NBS) underpinned by improved urban governance, and public and private participation can systematically integrate ecosystem services and biodiversity and advocate their benefits and values in urban planning to meet societal challenges including climate change resilience, public health and well-being, and social inclusion. Co-creation with urban planners, citizens and business in urban living labs and educational programs for children ensure long-term sustainability of solutions, and support to business development assist further realization. This to accelerate the crucial transition toward smart, green and healthy cities in Europe and China.

For proGIreg three front-runner cities (Dortmund (DE); Turin (IT); Zagreb (HR))will create Living Labs in urban areas which face the challenge of post-industrial regeneration. These areas suffer from social and economic disadvantages, inequality and related crime and security problems. They lack quality greenspaces, have a negative impact on human health and wellbeing and are more vulnerable to the effects of climate change. Going beyond the current state-of-the-art with Green Infrastructure as a one-off state intervention, the proGIreg Living Labs will develop NBS which are citizen owned and co-developed by state, market and civil society stakeholders. Innovation will take place on the technical level through the NBS deployments, on the social level through co-designing, co-creating and co-implementing NBS with local communities and on the economic level through combining NBS with market-ready business models. Four follower cities in Eastern and Southern Europe (Cascais PT, Cluj-Napoca RO, Piraeus GR, Zenica BA) will be co-steering the research process to assure replicability and adaptability to their local context resulting in urban plans for NBS deployment. The NBS to be tested i.a. include: regenerating industrial soils biotic compounds, creating community-based urban agriculture and aquaponics and making renatured river corridors accessible for local residents. Scientific assessment and monitoring results from the Living Labs will be made available on the EU NBS platforms OPPLA and THINKNATURE and will contribute to the European reference framework for NBS. Global impact will be achieved by a training programme for cooperative planning, implementation and management of NBS. It will be provided by partners from the cities, SMEs and universities involved. Training events will be organised in cooperation with the partner ICLEI. Massive Open Online Courses (MOOCs) will be distributed via EdX, the most renowned MOOCs platform worldwide.
