Session 35 - Circular economy and industrial symbiosis

Mediterranean (MED) islands and coastal areas are under pressure due to water shortage. Water reserves are depleted, while tourism in the summer months burdens the limited water sources. A persistent issue arising from the above activity is the increased seasonal loads of sewage that wastewater treatment plants (WWTPs) receive and need to cope with. On the top of that, the circular economy concept is not implemented in the MED region and particularly in small WWTPs. Water, nutrients, energy and chemicals contained in sewage are not usually valorized. At the same time, in several MED islands, energy intensive seawater desalination is applied to produce potable water thus increasing the energy demand and producing large quantities of brine water, which is not further valorized. As a consequence, activities within the concept of circular economy are required, considering the water-energy-food nexus. The HYDROUSA Horizon2020 Innovation Action project will provide innovative, regenerative and circular solutions for (1) nature-based water management of Mediterranean coastal areas, closing water loops; (2) nutrient management, boosting the agricultural and energy profile; and (3) local economies, based on circular value chains. The services provided lead to a win-win-win situation for the economy, environment and community within the water-energy-food-employment nexus.

The aim of green production and consumption is to adopt the idea of supplying the consumers with products that fulfill their needs with lower consequences on the environment. This concept, introduced in 1970, aims to protect the environment and to have better control over natural resources. This study is aiming at investigating the consumers’ purchase behaviors toward green products which can help decision-makers identify the tools that may be needed to promote green products in UAE markets. The study was conducted through the distribution of a self-administered questionnaire to assess green purchase practices and public knowledge about green products. The study concluded that the quality of green products is the most important factor that the UAE’s consumers consider for their decision regarding the green purchase. Eco-labeling may not be well understood among the studied population, and more awareness is needed about Eco-labeling among the community. This study showed that social media is a very important and effective tool to spread and influence green purchase practices among the residents.

Applying the principles of circular economy to agriculture is a very important contemporary issue on the international political and economic agenda. In this context, current knowledge and recent insights on biosurfactant production will be surveyed to apply these novel economic approaches in the field of agricultural waste valorisation.
The main objective of the CREIAMO project is to set up a replicable methodology for boosting the transition towards circular economy of the oil and wine production sectors through the creation of new destinations for residues originated, new options for their economic valorisation and new business models to increase the competitiveness of companies. A first pilot application will be run in the Lombardia Region. To achieve this objective, the project operates on different eco-innovation strategies:
a. Process and product eco-innovation for the exploitation of agriculture wastes from the production of wine and olive oil for producing eco-friendly biosurfactants. Cost-effective production methods will be implemented to improve its market profitability, resulting in higher yields and purity. In CREAIMO, theses bio value-added products will be, therefore, used to treat contaminated soil, which represents a main environmental issue.

For the purposes of the SWAN Project, an integrated suite of on-line resources and tools has been developed aiming to assess novel industrial business models based on solid industrial waste reuse. One of the major components of this platform is an inventory of commercially implemented best practices. This inventory will both inform all registered users about the current opportunities for waste reuse and also serve as the basis for the SWAN matching algorithm.
For all the practices or technologies included in the database, the following characteristics have been collected: (i) The type of the industrial plant supplying the waste stream; (ii) The type of the industrial plant receiving the waste stream; and (iii) The type of the waste stream exchanged between source and sink;
The Statistical Classification of Economic Activities in the European Community has been used for the categorization of the industrial plant types whereas for the waste streams both the European Waste Catalogue and the European Waste Classification for Statistics have been applied. The database has been populated with more than 100 entries and has led to the identification of the most common symbiotic opportunities based on solid waste reuse.

The SWAN platform is an integrated suite of on-line resources and tools for assessing industrial symbiotic opportunities based on solid industrial waste reuse. It has been developed for the purposes of the SWAN Project, a project of the transnational Cooperation Programme Interreg V-B “Balkan-Mediterranean 2014-2020” aiming to develop a digital solid waste reuse platform for the Balkan region and Cyprus.
The SWAN platform integrates a database with the spatial and technical characteristics of industrial solid waste producers and potential consumers, which will be populated with data from all four countries involved in the project; i.e. Greece, Bulgaria, Albania and Cyprus. It also incorporates an inventory of commercially implemented best practices on solid industrial waste reuse.
The SWAN platform hopes to be the facilitator in the development of novel business models based on solid industrial waste reuse in the Balkan region. Towards this end, it will allow the registered users to run the SWAN matching algorithms and identify and assess potential novel business models based on solid waste reuse, either for an individual industrial unit (source/potential receiver of solid waste) or a specific region.

Turning waste into new resources in small and medium sized enterprises (SME). During a three years period (2015-2018) a project involving SME's, was carried out in corporation of six Danish municipalities, the Technical University of Denmark (DTU) and Symbiosis Center Denmark. The project was financed by EU. The project focused on industrial symbioses, optimizing resources and/or potential waist minimalization. Initially 107 SME's where screened for their potential to join the project. Of these 52 SME's were offered a technical development plan and 42 SME's were offered a green development plan. The outcome of the project showed following potential savings: • Energy: 36.222 GJ/year • Materials: 10.416 tons/year • Water: 20.935 tons/year • CO2 emission savings: 4.908 ton/year This corresponds to 1 million euro saved. If all the proposed solutions are implemented, it will result in at least 24 new jobs in the participating SME's. Putting resource efficiency and industrial symbiosis on the agenda of small and medium-sized enterprises showed that sustainable growth can be achieved. It requires companies that are ready to think differently and are open to new ways of doing business.

The North Aegean Islands of Chios and Lesvos set recycling goals for organic residues from Municipal Solid Wastes (MSW). Both islands, in line with the National and Regional Plans for Municipal Waste Management, are discussing the approach of mechanical-biological stabilization MSW in combination with separated collection of biowastes and municipal pruning. The SusNisia-project, funded by BMU , adds Anaerobic Digestion (AD) to both approaches to demonstrate the added-value by production of biogas for energy purposes or as fuel for e.g. garbage trucks. The advantages of separated collection of organic input materials are the production of high quality and multi-purpose end-products to serve the goal of local nutrient recycling. As refinement, SusNisia applies digestate or compost from Biowaste-AD and char coal from municipal pruning for production of specific soil enhancement products e.g. for olive tree cultivation, vegetable farming and greenhouse applications. The char coal, as activated char, absorbs pollutions, provides a sink for carbon dioxide and delivers extended water storage capabilities. The paper focus on dry fermentation option with German technology for islands of Lesvos and Chios to demonstrate added value by sectoral coupling to integrated waste management systems.
