“…Only a handful of TEAs reviewed recognized two or more of the additional financial benefits of on-farm AD which may include the income from the sale of biofertilizers and co-products, the reduction of energy costs (for farm equipment, lighting, heating) and the reduction in chemical fertilizer use [ 24 , 31 , 32 ]. Including more inputs and outputs in the system boundary provides a more representative methodology that can include possible additional financial benefits of the technology and provide a more realistic estimate of the viability of on-farm AD.…”

“…In terms of LCAs, most studies follow the International Organization for Standardizations (ISO) 14040 and 14,044 standards [ 31 ] although, for Europe, the International Reference Life Cycle Data System (ILCD) handbook guide provides a detailed description on how to carry out the analysis following the definitions established by the European guidelines [ 32 ]. This includes the emissions analysis that needs to be set based on the REDII methodology to assess GHG emissions from the production and use of biomass-derived fuels; for the co-digestion of crop biomass this would include everything from the cultivation of the crop right through to biogas upgrading and/or injection for use as a transport fuel as shown in Eq.…”

Marginal Abatement Cost Curves compare and assess greenhouse gas mitigation options available to various sectors of the economy. In the Irish agricultural sector, large anaerobic digestion facilities are currently considered a high-cost abatement solution. In prior studies of anaerobic digestion abatement costs, two options were assessed: the generation of heat and electricity from biogas (115 €/tCO 2eq ) and the production of renewable heat from biomethane (280 €/tCO 2eq ). Both scenarios encompass single cost values that may not capture the potentially variable nature of such systems. In contrast, prior techno-economic analyses and lifecycle analyses can provide a comparison of the abatement costs of anaerobic digestion systems at a range of scales. This work compares two case studies (based on prior literature) for small and medium-scale on farm anaerobic digestion systems. The small-scale system is set in Ireland with cattle slurry collected in open tanks during the winter, while the medium-scale system is set in the USA with cattle slurry collected periodically indoors all year-round. It was found that the abatement cost can vary between −117 to +79 € per t CO2 eq . The key variables that affected the abatement cost were additional revenue streams such as biofertilizer sales, displaced energy savings, and additional incentives and emissions savings within the system boundary. Including only some of these options in the analysis resulted in higher abatement costs being reported. Based on the variation between system topologies and therefore system boundaries, assigning a single mitigation cost to anaerobic digestion systems may not be representative.

“…production and other biomass conversions. 53 Almost every electrochemical process will need a dedicated analysis effort to assess its economic feasibility and its remaining carbon footprint. While many TEA and LCA studies on electrifying chemical manufacturing have appeared, most of these lack those detailed, regional deployment considerations, as well as spatiotemporal aspects of variable electricity cost.…”

R&D on electrochemical approaches for chemical manufacturing is experiencing a renaissance, the direct result of society’s desire to reduce greenhouse gas emissions of the chemical industry, aiming to be carbon neutral by 2050. Two such processes have been performed for decades at scale: the chlor-alkali process that produces chlorine from aqueous sodium chloride, and the production of adiponitrile, an intermediate in the production nylon-6,6. Water electrolysis for hydrogen production is also being deployed now at scale. This report summarizes some of the many efforts to electrify chemical conversions, often using renewable feeds like water, CO2, and biomass-derived adducts, or waste-streams from other processes. Beyond efforts to reduce emissions, a very active research community also pursues a broad range of electro-organic conversions, some of which have major advantages over conventional reaction chemistries. Overarching challenges of implementing electrochemical manufacturing approaches are also discussed (e.g., limited familiarity with electrochemical processes in chemical engineering practice, insufficient availability of electrical power, and the variability of various renewable feeds).

“…For example, Salvador et al [17] identify drivers and barriers for CBE businesses and present regional differences in these aspects. Croxatto Vega et al [18] present an approach that allows the selection of an ideal technology for a given region based on economic and environmental criteria. However, concrete guidelines for region-specific technology selection in the context of CBE scenario building cannot be derived from these studies.…”

“…For this purpose, the analysis by Salvador et al [17] is not sufficiently refined in terms of both regionality and success criteria. The quantitative approach of Croxatto Vega et al [18] is suitable to support an informed choice among a small number of technology options. However, intensive data requirements make it difficult to be applied to a large number of technology options for scenario building.…”

Reflecting Regional Conditions in Circular Bioeconomy Scenarios: A Multi-Criteria Approach for Matching Technologies and Regions

The Circular Bioeconomy (CBE) combines the concepts of bioeconomy and a circular economy. As an alternative concept to the current fossil-based, linear economy, it describes an economy based on the efficient valorization of biomass. It is regional in nature and aims to improve sustainability. An analysis of the transition process, by identifying its success criteria and assessing its impacts through the modeling of technology-specific scenarios, is necessary to ensure that CBE concepts are sustainable. However, a comprehensive consideration of regional influences on both is lacking. Based on extensive literature research and an expert survey, we develop a multi-criteria approach where we (i) present a comprehensive catalog of CBE success criteria and discuss their region-specific characters and (ii) develop a methodology based on evaluation matrices that enable CBE technologies to be matched with regions. The matrices support the evaluation of technological and regional characteristics influencing successful CBE implementation. The results show that the success criteria “biomass resources”, “technological”, and “social” are perceived as highly important, and that most of the success criteria are both region- and technology-specific, highlighting the relevance of developing matrices to match them. We describe such matrices indicatively for the two broadest and most important success criteria clusters “social acceptance” and “biomass supply chain”. With this, we substantiate the regional nature of CBE and raise the awareness on the importance of considering regional conditions in CBE transition processes. Furthermore, we provide practical guidance on how regional conditions can be reflected in the selection of technologies, e.g., in regional CBE technology scenarios.
