Sewage sludge management is a pressing environmental challenge due to high greenhouse gas emissions and inefficiencies in traditional methods such as landfilling and incineration. This review explores emerging and transformative technologies that align with carbon sequestration and sustainable land use. Novel approaches such as biochar production via pyrolysis, CaO-based stabilization to form calcium carbonate (CaCO₃), and phosphorus recovery through struvite precipitation are emphasized for their dual roles in climate mitigation and enhancing soil fertility. Other innovative techniques, including hydrothermal carbonization and microbial stabilization, have been examined for their ability to stabilize carbon in persistent forms. This study highlights the novelty of combining carbon sequestration with nutrient recycling, which enables long-term environmental benefits. Biochar and Ca-based fertilizers demonstrate exceptional potential for integrating carbon capture with soil enhancement, whereas struvite offers an effective pathway for nutrient recovery. Environmental trade-offs—such as greenhouse gas emissions during treatment, potential contaminant risks, and energy demands—are assessed alongside the benefits of reduced synthetic fertilizer dependence, improved soil health, and carbon sequestration. Life cycle assessment (LCA) and economic analyses confirm the feasibility and sustainability of these technologies. This comprehensive review advances the understanding of innovative sewage sludge treatments, offering a framework for integrating carbon-negative solutions into waste management practices. Graphical abstract

The aim of the article is to identify problems and public expectations regarding parking and the application of different parking solutions. Based on the results of a CAWI questionnaire survey, an evaluation of selected parking solutions is presented. Among others, vertical parking has been taken into account, the use of which is associated with a reduction in the area required for parking and an improvement in environmental performance characteristics at the use stage. This study is part of the search for sustainable solutions in city logistics. The results of the study serve as an initial insight into the opinions of one group of users in the life cycle of a car park. They can be used as an introduction to the eco-design of parking solutions and to compare different parking systems. The study was carried out as part of a project entitled: “Analysis of the environmental impact of a vertical parking solution using life cycle assessment at the design stage” carried out at the Silesian University of Technology.
