The role of the bioeconomy based on the use of renewable resources and also on the valorization of bio-based waste could contribute to a higher degree of sustainability. In this sense, biobased processes and products should exhibit values for indicators that demonstrate and outperform their competing counterparts. To this end, it is essential to apply a methodology to conduct the assessment of environmental impacts and potential damages at a global level. Life cycle assessment (LCA) has proven to be a suitable method to study the environmental profiles and damage scores of products and/or processes within their life cycle. In this regard, LCA impact scores are transformed into planetary boundary (PB) values, for which a threshold has been previously established. This has been the focus of this article, in which the environmental sustainability ratios of different bioadhesive scenarios have been evaluated under the combined framework of PBs and LCA for wood-based bioadhesives following different allocation approaches based on egalitarian, utilitarian, and grandfathering principles. In this way, it has been possible to assess the potential of bioadhesives to replace synthetic resins in the wood-based panel production chain. The results obtained show some variability in the environmental profiles and indicators, but it is possible to conclude that the bioadhesives selected can be considered as sustainable alternatives. However, improvements are required in certain PB categories, such as climate change or biogeochemical flows, as in some cases, the threshold value is exceeded. Future research should focus on two strategic lines: the application of guidelines for the evaluation of environmental sustainability at the planetary level and the optimization of bio-adhesive production to reduce their impact with the aim of achieving a more adequate sustainability ratio.

“…The most widely used SNIs are nitrapyrin, dicyandiamide (DCD), and dimethylpyrazol (DMP)-based NIs ( Norton and Ouyang, 2019 ; Huérfano et al., 2022 ). However, SNIs are not exempt from some disadvantages, including production or management costs that restrict their use, notably in low-income countries, their limited action over time, variable effects on yield, or potential environmental toxicity ( Coskun et al., 2017b ; Sadhukhan et al., 2022 ). As a recent alternative, exploitation of the natural capacity of different plants to exudate compounds that suppress microbial nitrification, the so-called biological nitrification inhibitors or BNIs, is a promising strategy ( Subbarao and Searchinger, 2021 ; Lata et al., 2022 ; Saud et al., 2022 ).…”

BACKGROUNDSorghum (Sorghum bicolor L. Moench) is a cereal crop known for its biological nitrification inhibition (BNI) capacity, a plant‐mediated activity limiting nitrification pathway. The use of BNI‐producing plants represents an environmentally friendly and cost‐effective approach to reduce nitrogen (N) losses, such as nitrate (NO3−) leaching and nitrous oxide (N2O) gas emissions. The present study aimed to test the effectiveness of different S. bicolor cultivars in rotation to retain ammonium (NH4+) in soils and promote N availability for the subsequent wheat crop. A two‐year field rotation was established with four sorghum cultivars followed by winter wheat (Triticum aestivum L.). Urea alone or combined with the urease inhibitor N‐(n‐butyl) thiophosphoric triamide was applied to promote a NH4+‐based fertilization regimes.RESULTSAddingN‐(n‐butyl) thiophosphoric triamide maintained higher soil NH4+ content and reduced ammonia‐oxidizing bacteria population during sorghum cultivation. However, the benefits of the inhibitor on sorghum growth were cultivar‐dependent. Notably, the further reduction in ammonia‐oxidizing bacteria abundance for sorghum Voyenn and the increased soil NH4+ content for Vilomene suggested a BNI potential for these cultivars. Importantly, the Vilomene precedent enhanced wheat yield for both fertilization regimes.CONCLUSIONOverall, the present study confirms that sorghum is a suitable catch crop and emphasizes the importance of selecting the proper sorghum cultivar to maximize the yield of the target wheat crop, at the same time as minimizing N losses. Furthermore, developing combined strategies with selected sorghum cultivars and the application of urease inhibitors enables to enhance sorghum productivity as forage, achieving added value to the rotation. © 2024 The Author(s).
