Economic growth and ecological problems motivate industries to apply eco-friendly technologies and equipment. However, environmental impact, followed by energy and material consumption still remain the main negative implications of the technological progress in process engineering. Based on extensive patent analysis, this paper assigns more than 250 identified eco-innovation problems and requirements to 14 general eco-categories with energy consumption and losses, air pollution, and acidification as top issues. It defines primary eco-engineering contradictions, in case eco-problems appear as negative side effects of the new technologies, and secondary eco-engineering contradictions, if eco-friendly solutions have new environmental drawbacks. The study conceptualizes a correlation matrix between the eco-requirements for prediction of typical eco-contradictions on example of processes involving solids handling. Finally, it summarizes major eco-innovation approaches including Process Intensification in process engineering, and chronologically reviews 66 papers on eco-innovation adapting TRIZ methodology. Based on analysis of 100 eco-patents, 58 process intensification technologies, and literature, the study identifies 20 universal TRIZ inventive principles and sub-principles that have a higher value for environmental innovation. The presented research work belongs to the European project "Intensified by Design platform for the intensification of processes involving solids handling" (IbD, http://ibd-project.eu), funded by the European Commission under the Horizon 2020 SPIRE programme.

“…The selection and ranking method proposed by the authors is disclosed in (Livotov et al, 2019c). A thorough analysis of the TRIZ efficiency for process intensification is given in (Livotov et al, 2018): among other outcomes, the application of the proposed TRIZ inventive operators in 6 industrial case studies resulted in 230 ideas and 26 patentable value added design concepts. In general, the identification and application of strongest inventive operators for different eco-problems appears to be a promising and more precise ideation technique within the Eco-AIDA toolbox.…”

Process engineering industries are now facing growing economic pressure and societies' demands to improve their production technologies and equipment, making them more efficient and environmentally friendly. However unexpected additional technical and ecological drawbacks may appear as negative side effects of the new environmentally-friendly technologies. Thus, in their efforts to intensify upstream and downstream processes, industrial companies require a systematic aid to avoid compromising of ecological impact. The paper conceptualises a comprehensive approach for eco-innovation and eco- design in process engineering. The approach combines the advantages of Process Intensification as Knowledge-Based Engineering (KBE), inventive tools of Knowledge-Based Innovation (KBI), and main principles and best-practices of Eco-Design and Sustainable Manufacturing. It includes a correlation matrix for identification of eco-engineering contradictions and a process mapping technique for problem definition, database of Process Intensification methods and equipment, as well as a set of strongest inventive operators for eco-ideation.

“…The proposed concept for integration of the Quality Function Deployment and Importance-Satisfaction Analysis is illustrated below using an industrial case study dealing with the ceramic powder granulation [14] as presented in Table 1. Based on the information collected by the Process Mapping, the creation of the House of Quality and requirements ranking can be carried out in the following phases.…”

Growing demands for cleaner production and higher eco-efficiency in process engineering require a comprehensive analysis of technical and environmental outcomes of customers and society. Moreover, unexpected additional technical or ecological drawbacks may appear as negative side effects of new environmentally friendly technologies. The paper conceptualizes a comprehensive approach for analysis and ranking of engineering and ecological requirements in process engineering in order to anticipate secondary problems in ecodesign and to avoid compromising the environmental or technological goals. For this purpose, the paper presents a method based on integration of the Quality Function Deployment approach with the Importance-Satisfaction Analysis for the requirements ranking. The proposed method identifies and classifies comprehensively the potential engineering and eco-engineering contradictions through analysis of correlations within requirements groups such as stakeholder requirements (SRs) and technical requirements (TRs), and additionally through cross-relationship between SRs and TRs.
