This work presents an application of the TRIZ methodology to an industrial project dealing with laser pyrolysis of tires, bitumen, and other wasting materials. Usually in the literature you can find works that describe how to apply TRIZ to single cases of problem solving, to conceive new products or to strategic planning activities. In this paper instead we present a methodological approach that combines the use of different TRIZ tools to support an entire industrial project. Triz tools will be briefly introduced to show how they can be used to decide between different industrial pyrolysis technologies, identifying strengths and weaknesses of existing laser applications, suggesting patents around the existing idea, designing the innovative idea of a laser chamber to test the effectiveness of the process.

More in details, the evolution trees and the macro-micro law of technical evolution were revisited and suggested for analyzing and organizing results of a big search about the state of art. Contradictions and Ideal Final Result were used to analyze existent products and design the new ones. TRIZ methodology is also useful for building a storyboard able to convince other stakeholders of the credibility of the results and to create a team of companies and academics willing to invest in such a pioneering idea.
