This study proposes a methodology to assess the environmental and economic performance of bio-based lactic acid (LA) production by scaling up from pilot to industrial levels using fiber sludge, a residue from the pulp and paper industry, as a feedstock. Process design, Techno-Economic Analysis (TEA) and Life Cycle Assessment (LCA) were conducted at pilot scale to identify key environmental and economic hotspots. External costs were estimated following the environmental Life Cycle Costing (eLCC) approach using the Environmental Prices (EP) method. At the pilot scale, the LCA indicated a Global Warming Potential (GWP) of 3.87 kg CO₂-eq, which aligns with the values reported in previous studies. Scaling up to different plant capacities revealed the potential economies of scale. At a production rate of 50 kt per year, the Minimum Selling Price (MSP) was estimated at 1.71€/kg, which is comparable to that of other bio-based LA production routes. Assuming proportional environmental impacts from pilot to industrial scale, external costs were integrated into the MSP, resulting in adjusted values of 2.04€/kg (lower value), 2.21€/kg (central value), and 2.46 €/kg (upper value). Sensitivity and uncertainty analyses using Monte Carlo simulations indicated an 87.5 % probability of achieving a positive Net Present Value (NPV). This study highlights the need for standardised methodologies to evaluate the environmental and economic impacts of emerging bio-based technologies, particularly when accounting for external costs.

Su obra, profundamente experimental, arriesgada y cargada de reflexión, la sitúa como una verdadera aventurera del panorama teatral actual. Velasco es una figura transgresora que desafía las estructuras tradicionales del género, explorando temas como la identidad, la memoria, el deseo y las tensiones sociales, con un enfoque comprometido que entrelaza lo íntimo y lo político. Sus piezas no solo interpelan al espectador a través del lenguaje, sino también mediante un impacto visual y emocional cuidadosamente orquestado. Además, su trabajo no se limita al texto, sino que concibe la puesta en escena como un espacio multidimensional donde confluyen disciplinas como la danza, la música y las artes visuales. Esta versatilidad y profundidad se reflejan en su última creación, Primera Sangre, galardonada con el XXXI “Premio SGAE” de Teatro Jardiel Poncela en 2022. En este texto, Velasco apela a una sociedad más justa e inclusiva, desafiando las normas establecidas y reafirmando su compromiso con la transformación social a través del arte.

Drawing on agency theory and the resource-based view, most studies examine family involvement in ownership and management, which reflects the family’s ability to make decisions. Other studies emphasize the family’s willingness to pursue specific objectives, particularly those related to socioemotional wealth. However, particularistic behavior in family firms cannot be explained solely by ability or willingness. Building on this reasoning, we propose that both ability and willingness are necessary but individually insufficient conditions for explaining family firm performance. We further argue that their joint presence constitutes a sufficient condition. Using a sample of 141 family firms, our results identify seven configurations combining measures of ability and willingness that are associated with high financial performance, thereby supporting our arguments.
