**3. Economic Analysis of the Proposed Biorefinery Concept**

*3.1. Assumptions for the Different Biorefinery Technologies*

The biorefinery concept presented in this study aims to produce EOs and biomethane as the main products. The main goal is to assess the basic conceptual, economic, and financial viability of the concept and to identify the main costs and benefits of the proposed multi-product biorefinery.

Considering the details given in Section 2, the initial assumptions for the pre-feasibility assessment are presented in Table 1.
