- A company-basedvView on sustainable packaging orientationPublication . Duarte, Paulo; Ribeiro, Maria Inês; Silva, Susana C.; Pinhal, Rúben; Estima, AnaThis study aims to understand how companies address and integrate sustainability challenges in packaging design, as well as the motivations and processes that influence managers’ decisions when adopting sustainable practices. Semi-structured interviews were conducted with managers from five major Portuguese companies to gather qualitative data on the motivations and processes related to sustainable packaging strategies and actions. The list of questions was developed based on the literature review, from which the dimensions to be analyzed were identified. The results indicate that several factors influence companies’ decisions regarding sustainability in packaging. Despite some factors being beyond the control of companies, the interviews reveal that companies possess the necessary knowledge and are committed to adopting more sustainable packaging.
- Simplified, high yielding extraction of xylan/xylo-oligosaccharides from palmaria palmata: the importance of the algae preservation treatmentPublication . Coelho, Diogo; Costa, Diogo Félix; Barroca, Mário; Cunha, Sara Alexandra; Pintado, Maria Manuela; Abreu, Helena; Martins, Margarida; Collins, TonyThe complex plant cell wall heteropolysaccharide xylan, and its breakdown products xylo-oligosaccharides and xylose, are value-added compounds with a plethora of potential applications in diverse areas. They are nonetheless currently poorly exploited, with a major bottleneck being the unavailability of efficient, low-cost, high-yield production processes. The major objective of the present study is to identify and characterise a high-yield process for the preparation of highly pure xylan/XOS products from the macroalga Palmaria palmata. Currently, most xylan is extracted from land-sourced lignocellulosic feedstocks, but we take advantage of the high xylan content, xylan aqueous solubility, lignin-free nature, weakly linked cell wall matrix, and sustainability of the macroalga to identify a simple, sustainable, high-yield, novel-xylan-structure extraction process. This is composed of five steps: alga oven drying, milling, aqueous extraction, centrifugation, and dialysis, and we show that the alga preservation step plays a critical role in component extractability, with oven drying at high temperatures, ~100 °C, enhancing the subsequent aqueous extraction process, and providing for xylan yields as high as 80% of a highly pure (~90%) xylan product. The process developed herein and the insights gained will promote a greater availability of these bioactive compounds and open up their application potential.
- Empowering women in decision-making about mobility during labor: insights from expertsPublication . Lopes, Marlene I.; Vieira, Margarida; Cardoso, AlexandrinaINTRODUCTION: Allowing freedom of movement and positions during labor facilitates safe progression, improves maternal and neonatal outcomes, and contributes to a positive birth experience for women and their partners. Childbirth preparation aims to empower women by equipping them with skills and confidence to manage labor actively and knowledgeably. However, in many hospital settings, women's mobility remains restricted. This study explores expert perspectives on the core components of an intervention designed to promote women's autonomy and active participation during labor, to be implemented by nurse-midwives within Childbirth Preparation Programs in primary healthcare. METHODS: A qualitative study was conducted in February 2024 in Portugal, using a focus group composed of ten nurse-midwives recognized as experts in childbirth preparation. The session was recorded and analyzed through content analysis, guided by the Theory of Emancipated Decision-Making in Women's Healthcare. RESULTS: Nine women and one man participated, aged 34-64 years, representing primary healthcare, hospitals, and academia. Six key themes emerged from the analysis: the intentionality behind the intervention; understanding the meanings and expectations women hold about their birth experience; empowering women by providing knowledge and skills; raising awareness of social norms that may influence women's decisions and actions; encouraging women to reflect on their options; and fostering woman-centered care. CONCLUSIONS: The experts emphasized the importance of promoting mobility during labor to enhance perinatal outcomes and the childbirth experience. Empowering women through experiential learning, fostering reflection, supporting informed choices, and ensuring continuity of care through collaborative professional practices were identified as essential strategies for effective intervention.
