The growing demand for chicken meat products has increased the amount of wastewater associated with their production; treatment generation sludge and oils trapped in trap process treatment. This work presents a valorization this residual oil recovered through production biodiesel. An degumming was applied, quality treated evaluated. transesterified alkaline conditions homogeneous catalyst (KOH); 3k experimental design applied two factors: temperature at 50, 60, 70 °C molar ratios 5, 6, 7 moles methanol per mole oil. biodiesel parameters were evaluated based on ASTM standard. achieved yield 90.2%. obtained met all parameters; however, only ratio 6:1 60 kinematic viscosity 5.64 ± 0.15 mm2 s−1, meeting limits 1.9–6.0 s−1 regulation. fluidity mixtures 25, 75% v petroleum diesel also evaluated, better adjustment Bingham mixing rule model rheological analysis revealed that did not lose Newtonian behavior. allows application internal combustion engines, achieving

This study pioneers a combined Life Cycle Assessment (LCA) and Costing (LCC) evaluation of an industrial symbiosis (IS) case involving waste heat recovery from pulp paper mill to tomato greenhouse in Sweden. Unlike previous studies that assess environmental or economic aspects separately, this research provides holistic assessment quantifying both burdens feasibility. A comparative analysis framework is applied, evaluating symbiotic real versus conventional production the Netherlands subsequent import LCA examines gas emissions, eutrophication, toxicity, land use, resource depletion, while LCC assesses total ownership costs, including Capital Operational Expenditures. The findings demonstrate IS scenario significantly reduces emissions operational costs enhancing energy efficiency. work fills gap literature, offering replicable for sustainable operations. results highlight potential improve efficiency, promote circular economy strategies, foster practices agri-food sector.

The convergence of waste-to-energy innovations and the tourism industry presents a dynamic frontier with significant potential for sustainable development. As continues to grow globally, environmental footprint waste generated by this sector is becoming increasingly concerning. Waste-to-Energy (WtE) technologies, crucial role technology providers, offer promising solution converting into usable energy, thereby reducing impact promoting circular economy. This paper explores future trends opportunities in integrating WtE systems within industry. By embracing innovations, can significantly reduce its burden, lower energy costs, contribute more future. chapter underscores necessity multidisciplinary collaboration supportive regulatory frameworks fully realise technologies transforming landscape tourism.
