Amid the UN Decade on Ecosystem Restoration and the EU's Nature Restoration Regulation (NRR), which aims to restore degraded areas in the coming decades, post-mining sites must be integrated into biodiversity and ecosystem recovery strategies as key contributors. While mining, quarrying, and other extractive activities have considerable environmental impacts, they also present massive opportunities to create valuable habitats, support biodiversity, guide restoration efforts, and contribute to conservation. A strong foundation of scientific and practical knowledge is already in place, yet implementation gaps persist, and regulatory frameworks remain under-utilised for restoring these degraded areas.

Towards syngas biorefineries: The potential of microbial consortia for syngas valorisation.

Biotechnol Adv

August 2025

Institute of Sustainable Processes, Dr. Mergelina, s/n, 47011 Valladolid, Spain; Department of Chemical Engineering and Environmental Technology, School of Industrial Engineering, University of Valladolid, Dr. Mergelina, s/n, 47011 Valladolid, Spain. Electronic address:

Gasification has emerged as a promising platform to cope with recalcitrant organic waste within the framework of biomass-based biorefineries, producing syngas that can be fermented into valuable bioproducts. Despite its potential, syngas fermentation is based predominantly on pure cultures, which faces significant challenges, including the limited portfolio of generated compounds (primarily acetate and ethanol) and their low productivity. To address these bottlenecks, the potential of microbial consortia as effective platforms for syngas conversion has been evaluated.

Reducing carbon footprint in high HS emissions: A synergistic microalgal-bacterial solution for sugarcane biorefineries.

J Hazard Mater

Institute of Sustainable Processes, Dr. Mergelina, s/n, Valladolid 47011, Spain; Department of Chemical Engineering and Environmental Technology, School of Industrial Engineering, University of Valladolid, Dr. Mergelina, s/n, Valladolid 47011, Spain. Electronic address:

Sugarcane vinasse, a major by-product of ethanol production, poses environmental and health risks due to its high sulfate content, promoting severe hydrogen sulfide (HS) formation (up to 50,000 ppm) during acidogenic fermentation. The resulting HS and high carbon dioxide (CO) levels in off-gas create serious hazards, often leading to conventional desulfurization systems' clogging and high maintenance. This study is the first to investigate a Chloroidium-based combined microalgal-bacterial (CMB) system for simultaneous, high-strength HS abatement and CO sequestration from these challenging vinasse fermentation off-gas streams.

South China University of Technology, SCUT-Zhuhai Institute of Modern Industrial Innovation, School of Food Science and Engineering, Overseas Expertise Introduction Center for Discipline Innovation of Food Nutrition and Human Health, Guangdong Province Key Laboratory for Green Processing of Natural

Intact pulse cotyledon cells are known for their intact cellular structure and dense protein matrix, leading to slower starch digestibility. However, the retrogradation and digestibility of retrograded intracellular starch has rarely been investigated, and our preliminary results indicated the difficulty of intracellular starch retrogradation. To test mechanistic principles of intracellular starch retrogradation, intact pulse cells were extracted and treated with protease followed by pancreatic α-amylase (0-20 min) and pullulanase (24 h) prehydrolysis, and then controlled retrogradation (4 °C, 5 d).
