Abstract: A new ontological framework which supports processing technologiesparticipation in Industrial Symbiosis (IS) is proposed. The frameworkuses semantic web service formalism to describe technology based ontacit knowledge embedded in the domain ontology and explicit knowledge acquired from the users. To enhance technology discovery, IS relevantprocessing technology classification and characterization is proposed.Technology participation in IS is addressed. Partial semantic input–output matching is used to propose complex and innovative networks assessed and ranked by their technological, economic and environmental benefits. The proposed framework is implemented as a web service and operation demonstrated using a case study.

Abstract: Industrial symbiosis (IS) is a subdiscipline of Industrial Ecology that aims to bring together companies from different sectors to shareresources, namely energy, materials, and water. The main goal of IS isto improve resource (materials, waste, energy) efficiency and lead tomutual environmental, financial and social benefits to participants. In this paper we present a semantic approach for IS input/output matching. This approach is based on knowledge modelling and ontologies. Ontologies are used to model all resources – waste, water, energy – along with details about their composition, characteristics (chemical and physical)and tacit knowledge about their flow. The input/output matching algorithm presented enables the valorisation of resources through industrial symbiosis networks.

Abstract: Industrial Symbiosis (IS) is a growingly accepted paradigm forprocessing waste into material, energy and water with benefits toparticipants measured by economic, environmental and social gains.Despite of some attempts to quantify them no unified metrics or methodsfor calculating concomitant indicators have been proposed. This paperpresents a systemisation of IS relevant environmental metrics and asemantic approach based on knowledge modelling using ontologies tofacilitate “a priori” calculation of respective indicators. The approach and metrics are presented and verified with a case study.

Abstract: Th epaper introduces a new paradigm for Industrial Symbiosis by pioneering the use of ontology engineering in the field. Semantics are used tomodel Industrial Symbiosis flows, to model enabling technologies and tosystematise the development of a matching service. Combined with a systems engineering approach, semantics further combine tacit knowledgefrom Industrial Symbiosis experts with explicit knowledge fromIndustrial Symbiosis participants. The new approach promises systematicvenues to discoveries, innovative solutions, and a holistic methodologyin the development of Industrial Symbiosis networks. The paradigm has been implemented as a multilingual web service to support Industrial Symbiosis communities and to embrace small and medium enterprises that are currently side-lined from developments. The approach has been testedand validated using real-life data and its functions are demonstrated with illustrative examples.

Abstract: Ontologies and semantics are widely used in many areas in an effort to enable the sharing, reusability and interoperability of knowledge.Industrial Symbiosis (IS) is an area which can be highly benefited bysuch technologies in order to eliminate the jargon barriers that exist in the resource/waste and processing technologies domains. In this paper, we present the use of these technologies in IS practice by demonstrating the development of different knowledge models that exploit the potential of semantics in order to automate the IS practice andmake it more effective.

Abstract: Industrial Symbiosis (IS) is an innovative approach that bringstogether companies from different sectors in an effort to improve resource efficiency. This paper introduces a semantically enabled web platform that supports and automates the application of IS. The platformis based on the semantic formalisms for the waste and processing technology classifications, further supported by the semantic webservices technology in the process of establishing synergies.

Abstract: This paper proposes an ontological framework to support IndustrialSymbiosis (IS) operation. The framework exploits semantic knowledgemodeling and enables structural data transformation for identificationof potential synergies between various industries and hence formation of one to one and complex symbiotic networks.

Abstract: Industrial Symbiosis (IS) is an ecological approach aiming to promote waste valorization opportunities. To date, efforts related to IS process rely on data generated in the aftermath of IS network formation. We propose the integration of the process of screening of IS network options and optimisation of respective environmental performance with the use of semantics.

Abstract: The potential of ontologies and knowledge modeling in process systems engineering has been realised and researched, efforts were directed to create semantic models representing the process industry domain. In this paper we present a re-usable ontology that consists of two main classification modules: i) Waste and ii) Processing Technology. The ontology has been developed, validated and used for processing of waste within the framework of Industrial Symbiosis. It supports a web platform that enables Industrial Symbiosis practice. The ontology is used for collecting information, user registration and semantic input output matching.
