  3. Introduction Methodology Results Conclusions Thyme ( Thymus vulgaris ) It is among the most produced species in Colombia, which is found in difgerent areas of the country. The multiple extractive components that thyme contains make it have a potential for use towards difgerent value-added products. Polyphenolic compounds and essential oil are important due to they have a wide range of biological functions [3]. 3 Research group: chemical, catalytic and biotechnological processes

  15. Introduction Methodology Results Conclusions Conclusions -The results showed the pre-feasibility to extract antioxidant compounds from thyme as raw material by solvent extraction through stand-alone way at difgerent scales. However, in the case of the biorefjnery approach a very high scales are required . -The conditions proposed in this paper, make the stand-alone process approach more viable than the biorefjnery approach. However, there are difgerent ways to do the biorefjnery process more profjtable based on the use of more effjcient extraction and energy technologies. Additionally the key point is the interest for the total use of raw materials to avoid contamination. -Other important aspect assessed in this study case is the Potential Environment Impact (PEI) as environmental indicator. It was achieved less PEI in the stand-alone than biorefjnery approach. It is possible to affjrm that a large part of the 15 environmental impact potential is due to energy consumption.
