“…Therefore, how much biogas (or biomethane) from a biogas plant should be directed to MP production depends on the feedstocks which are processed in the biogas plants. For instance, regarding a biogas plant mono-digesting biopulp (i.e., source sorted organic fraction of municipal solid waste treated with pulper technology [40]). With a TS of 18.3%, 176.48 kg biogas per tonne of biopulp (with 60% methane) can be produced.…”

“…Early studies such as Zondervan et al (2011b) analyzed the pathways for the conversion of LCF and crude oil into ethanol, butanol, succinic acid, and blends of these compounds with gasoline. A recent study by Elyasi et al (2021) aimed to identify the best pathway for producing energy and chemicals from biomass. This work emphasizes building a comprehensive network of processing pathways and corresponding process data to convert LCF and other organic wastes (e.g., manure) into value-added chemicals and energy.…”

Optimal Conversion of Organic Wastes to Value-Added Products: Toward a Sustainable Integrated Biorefinery in Denmark

It is crucial to leave behind the traditional linear economy approach. Shifting the paradigm and adopting a circular (bio)economy seems to be the strategy to decouple economic growth from continuous resource extraction. To this end, producing bio-based products that aim to replace a part, if not all, of the fossil-based chemicals and fuels is a promising step. This can be achieved by using multi-product integrated biorefineries that convert organic wastes into chemicals, fuels, and bioenergy to optimize the use and close the materials and energy loops. To further address the development and implementation of organic waste integrated biorefineries, we proposed the open-source organic waste to value-added products (O2V) model and multi-objective optimization tool. O2V aims to provide a quick and straightforward holistic assessment, leading to identifying optimal or near-optimal design, planning, and operational decisions. This model not only prioritizes economic benefits but also takes on board the other pillars of sustainability. The proposed tool is built on a comprehensive superstructure of processing alternatives that include all stages concerning the conversion of organic waste to value-added products. Furthermore, it has been framed and formulated in a “plug-and-play” format, where, when required, the user only needs to add new process data to the structured information database. This database integrates data on (i) new processes (e.g., different conversion technologies), (ii) feedstocks (e.g., composition), and (iii) products (e.g., prices), among others. Due to Denmark’s high availability of organic waste, implementing a second-generation integrated biorefinery in Denmark has been chosen as a realistic showcase. The application of O2V efficiently led to the identification of trade-offs between the different sustainability angles. Thus, it made it possible to determine early-stage decisions regarding product portfolio, optimal production process, and related planning and operational decisions. Henceforth, it has been demonstrated that applying O2V aids in shifting the fossil to bio-based production, thereby contributing to the switch toward a circular bioeconomy.

Multi-product biore neries are very promising industries to diversify the economy of countries since they have a productive matrix with a biological characteristic capable of processing various types of biomass with applications in pharmaceutical, renewable energy, and other industries. In this context, this research carries out an analysis of the literature on biore neries and the methods of assessing social impacts that consider quality of life, employment, and stakeholders, among other metrics, as guided by the United Nations -UN. A systematic review combined with bibliometric, semantic, and content analysis was carried out by searching scienti c documents in the Scopus and Web of Science databases. A total of 116 articles were located, of which twenty-three were selected by three researchers to compose the research. The Fleiss Kappa Index was applied to verify the agreement of the evaluators' decision regarding the inclusion and exclusion of articles, they obtained K = 0.43 above the tolerable limit de ned for the inclusion of articles, which is K ≥ 0.21Therefore, all twenty-three articles were included. The results indicate that most biore nery projects consider optimization and econometric methods and especially the employment metric, therefore, understood as insu cient for assessing social impacts. On the other hand, projects whose methods consider Social Life Cycle and Multicriteria are more consistent for assessing the social impacts of biore neries, as they allow an analysis of qualitative and signi cant information.
