Periodic Reporting for period 1 - BIN2BEAN (Boosting the market deployment of safe, effective and sustainable innovations for soil improvement from bio-waste, towards regenerative soil systems)

In this context, BIN2BEAN aims to help EU cities in their transition towards healthy soils and soil regenerative systems, by optimizing bio-waste recycling into soil improvers through innovative and economically viable value chains. BIN2BEAN concept focuses on identifying, evaluating, and scaling up promising local initiatives and practices that can be tailored to diverse urban realities. The project adopts a circular, multi-actor and evidence-based approach, implemented through 3 Living Labs (LLs) in Amsterdam, Hamburg and Egaleo, representing different pedo-climatic, social and regulatory contexts and serving as hubs for co-creation, stakeholder engagement and real-life testing of bio-waste valorization pathways.
Activities include mapping of local contexts, assessment of existing solutions’ environmental and socio-economic performance, and development of a scoring system to identify the most promising options. In parallel, BIN2BEAN co-designs circular business models and explores governance and policy frameworks to support implementation and replication. Through this integrated approach, BIN2BEAN delivers a toolbox for empowering cities in adopting and scaling efficient, sustainable and market-ready solutions for bio-waste valorization into soil improvers.
In parallel, a Stakeholder Forum with 50 members was established to foster knowledge exchange and support the co-design of locally adapted biowaste management systems. A mix of participatory and analytical methods was deployed to understand urban biowaste flows, including Material Flow Analyses (MFAs) conducted in Hamburg and Amsterdam to identify waste generation hotspots and design fit-for-purpose interventions. In Egaleo, where no bio-waste was previously converted into soil improvers, this activity created the opportunity to build a circular system from scratch.
In terms of knowledge building, BIN2BEAN produced a wide European-scale overview of the bio-waste management landscape, integrating information from over 50 technical publications, 15 expert interviews, 455 citizen responses, and 18 surveys to EU cities. This resulted in a handbook of good practices and recommendations for bio-waste valorisation with a back-to-soil objective.
Scientific activities focused on developing a conceptual evaluation framework to assess soil improvers’ impacts on soil health and ecosystem services, drafting of QA/QC protocols, developing a protocol for laboratory analysis of carbon and nitrogen mineralization rate, with early experimental work conducted in Hamrburg. Additionally, recognizing that good quality soil improvers start from well-sorted biowaste, pilot urban actions were launched, notably in Egaleo, with the distribution of bio-bins and home composting initiatives, and the setting up of a grinder system in Amsterdam.
To support the selection and uptake of the most promising solutions, BIN2BEAN initiated the development of a scoring system integrating environmental, technical, and socio-economic indicators, with a demo version presented to partners. Complementary to this, early market assessments, preliminary feasibility studies and willingness-to-pay/accept analyses were undertaken. A survey was also launched to identify training needs along the value chain, supporting future capacity-building actions for innovators and local entrepreneurs.
A novel contribution to impact assessment is the novel evaluation framework to assess soil improvers holistically in terms of their performance on soil quality and climate. This includes the design of a conceptual model linking ecosystem stressors to functional soil health damage pathways, applying LCIA principles. This methodological innovation provides the basis for a harmonised environmental performance benchmark for bio-waste-derived soil improvers. The scoring system under development further distinguishes BIN2BEAN from existing initiatives. While MCDA approaches are common, BIN2BEAN’s tool is uniquely tailored to the biowaste-to-soil value chain, integrating environmental, economic, technical indicators into the decision logic.
