The use of lignocellulosic biomass to produce commercial high-value products has taken force in recent years. Aromatic plants are key raw materials to obtain bioactive compounds with high added value, such as phenolic compounds, but its extraction produces a high amount of wastes. In this sense, the present work aimed to evaluate experimentally the extraction of phenolic compounds from thyme and subsequently, the production of biogas from the remaining of the extraction. To evaluate the prefeasibility of the processes, the simulations of the stand-alone (conventional extraction), as well as the biorefinery (phenolic compounds extraction, biogas production, and a cogeneration system), were carried out and evaluated according to technical, economic, and environmental approaches. The bioactive compound extraction yield was 11.95% (w/w) and the methane yield was 114 ml/g volatile solids. In the present work, it was suggested that the stand-alone process becomes to be profitable from a small scale (23 T/day) in comparison with the biorefinery approach, which needs to be worked on a major scale (61 T/day) to be economically feasible. The comparison of the environmental impact generated by each scheme shows the major impact for the biorefinery case.

近年来，木质纤维素生物质用于生产商业高价值产品的使用已得到广泛应用。芳香植物是获得具有高附加值的生物活性化合物（例如酚类化合物）的关键原料，但其提取会产生大量废物。从这个意义上说，本工作旨在通过实验评估从百里香中提取酚类化合物，然后从剩余的提取物中生产沼气。为了评估流程的可行性，我们根据技术，经济，经济，社会，文化等方面对独立（常规提取）以及生物精炼厂（酚类化合物提取，沼气生产和热电联产系统）进行了仿真。和环境方法。生物活性化合物的提取率为11。95％（w / w），甲烷产率为114ml / g挥发性固体。在目前的工作中，有人建议，与生物炼制方法相比，单机工艺从小规模（23吨/天）开始就可以获利，而生物炼制方法需要大规模（61吨/天）进行操作。在经济上可行。每个方案产生的环境影响的比较显示了对生物精炼厂案例的主要影响。
