“…Additionally, there is a substantial lack of publications based on experimental as well as on modeling data comparing different conversion and downstream processing technologies (of lignocellulosic biomass). Exemplary reference works for fast pyrolysis are the study by Peters [56] and publications by Jones [57,58]. These investigations address technological, economic, and environmental aspects of fast pyrolysis and downstream processing technologies, primarily based on their own experimental and modeling results.…”

Opportunities and Challenges of the European Green Deal for the Chemical Industry: An Approach Measuring Innovations in Bioeconomy

The Circular Economy Action Plan, as part of the European Green Deal announced by the European Commission, is highly relevant to the chemical industry in relation to the production of sustainable products. Accordingly, the chemical industry faces the question of how far it can promote its own manufacture of sustainable products. Within this context, this article presents an approach on how to measure innovations in bioeconomy. The methodological framework developed provides the chemical industry with an approach to assess the effectiveness of innovative conversion technologies producing biogenic intermediate products (e.g., bulk chemicals). The innovations within the bioeconomy (TRL > 4; TRL—technology readiness level) are compared in terms of technical, economic, and environmental indicators for the current status, for the medium- and long-term as well as for different production sites. The methodological approach developed here is exemplarily applied, assessing the production of intermediate biogenic products via thermo-chemical conversion of lignocellulosic biomass. The results show the successful applicability of the developed assessment approach as well as significant differences in efficiency, costs, and environmental impact, both from the perspective of time and in spatial terms within the European Union. Thus, the methodological approach developed and presented enables the chemical industry to reduce challenges and to take advantage of the opportunities arising from the transition to a climate-neutral and circular economy.

As dairy industries increase across Australia, the amount of dairy waste is also on the rise. Australia annually production stands at around 377 727 t of cheese, 273 425 t of milk powder and 92 698 t of butter, and it is the third largest exporter of milk. The waste produced by these industries is considered a potentially valuable resource, and an environmental pollutant if not appropriately managed. The focus of this review is to evaluate the potential of converting typical Australian dairy industry waste into sustainable energy. Five fundamental methods including transesterification, pyrolysis, anaerobic digestion, steam reforming, and hydrothermal carbonization are discussed. Their technological merits, demerits and adaptability from the perspective of Australia are examined. The properties of representative wastes are also considered for the different energy conversion processes. This review aims to highlight the potential use of dairy industry wastes as feedstock for the emerging renewable energy sector.

Low-temperature hydrogenation of carbonyl compounds can greatly improve the thermal stability of fast pyrolysis bio-oil, thereby enabling long-term operation of upgrading reactors which generally require high temperatures to achieve deep deoxygenation. The state-of-the-art hydrogenation catalysts, precious metals such as ruthenium, although effective in carbonyl hydrogenation, deactivate due to high sulfur sensitivity. In the present work, we showed that molybdenum carbides were active and sulfur-tolerant in low-temperature conversion of carbonyl compounds. Furthermore, due to surface bifunctionality (i.e., both metallic and acid sites present), carbides catalyzed both CO bond hydrogenation and C−C coupling reactions. Combined, these reactions transformed carbonyl compounds to more stable and higher molecular weight oligomeric compounds while consuming less hydrogen than pure hydrogenation. The carbides proved to be resistant to other deactivation mechanisms including hydrothermal aging, oxidation, coking, and leaching. These properties enabled carbides to achieve and maintain good catalytic performance in both aqueous-phase furfural conversion and real bio-oil stabilization in the presence of sulfur. This finding strongly suggests that molybdenum carbides can provide a catalyst solution necessary for the development of practical bio-oil stabilization technology.
