The emergence of self-organized industrial symbiosis (IS) is based on the expectations of industrial actors regarding financial and/or environmental benefits through symbiotic inter-company linkages. One such linkage is the exchange of by-products as substitutes for primary raw materials. However, the company generating the by-product may even not be aware of potential application fields in other industries. In cases where the by-product triggers an innovation, the very early phase of the innovation process (“early front-end”—EFE) is extremely important, as it is here that a first rough picture of future application fields must be defined. In contrast to traditional market innovations of industries, the EFE of IS innovations is triggered by the existence of a certain by-product. As conventional innovation models are not very helpful in supporting the EFE decisions in IS innovations, our paper aims to establish a link between self-organized IS and innovation by creating a specific theoretical framework for the support of EFE decisions. We thus introduce the “stage-gate model of self-organized IS innovations” and place a particular emphasis on the early phases within this model. Subsequently, we illustrate the application of the early phases of the model in a case study on lignin utilization in the Austrian paper and pulp industry (P&P industry). In this way, the study contributes to a better understanding of the peculiarities and conditions of EFE decisions in IS innovations and their significance in the emergence of self-organized IS networks.
