  2. 2. Measuring the Political Legitimacy of Biorefineries in Europe

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Rachelle Bissett-Amess; [2007]
    Keywords : Cognitive legitimacy; political legitimacy; integrated industrial biorefinery; Environmental studies; Miljöstudier; Earth and Environmental Sciences;

    Abstract : It is likely that a high degree of political support will be required to realise the biorefinery concept in reality, as capital intensive technology development and stimulation of the most promising technologies for biorefineries requires that government will need to invest heavily before industry has the confidence in biorefinery technologies and bio-based product markets to invest fully. However, among the many problems facing such an innovative business concept as biorefineries, their relative lack of 'political legitimacy' is especially critical, as both entrepreneurs and crucial stakeholders may not fully understand the nature of biorefineries, and their conformity to established institutional rules (cultural norms and laws) may still be in question.
