Environmental Impact Assessment of an Intensive Pig Farm

Nowadays, the meet industry and intensive farming is in the crosshairs of environmentalists and organizations fighting climate change. In Spain, the controversy arose after the declarations of the minister of consumes, which explained in an interview that the meet sector contributes a 14.5% of the total emissions of CO2 and that the consumption of animal-derived food should be reduced. Slurry, which is the combination of cleaning water, animal excretions, bedding, and food leftovers, has been used during many years as fertilizers, but in these times, the water pollution due to nitrates in some parts of Spain surpasses the allowed by the OMS. Pigs are amenable to many different styles of farming, from intensive commercial units to commercial free-range enterprises, or extensive farming. Commercial farms house thousands of pigs in climate-controlled buildings. The goal of the present study is to assess the environmental impact of an intensive pig farm regarding odors, soil and groundwater pollution and waste treatment. Hence, first, the dimensioning of the farm and the characterization of a treatment plant is performed to later, present different scenarios. This provides hints of specific requirements needed by policy makers to establish minimum requirements for the installation of new facilitiesObjectius de Desenvolupament Sostenible::11 - Ciutats i Comunitats Sostenible

Projection-based hyper-reduced order modeling of stress and reaction fields, and application of static condensation for multibody problems

Computational Mechanics' problems are often solved using the Finite Element Method (FEM). The resulting systems of equations may lead to large data and therefore, the solution requires high memory and time to be computed. This situation can be surpassed by applying Reduced Order Modeling (ROM) techniques, allowing the user to capture the system's dominant effects to build a high-fidelity reduced model that gives the possibility to predict and analyze the behaviour of a complex model using low computational resources within a micro time-step. This paper aims to enrich the already implemented Kratos' Rom Application with a reconstruction of the reaction and 2nd Piola Kirkchhoff stress fields. The applied methodology is a projection-based strategy using the Proper Orthogonal Decomposition together with a Gappy Data reconstruction technique. The gappy data comes from building a hyper-reduced order model (HROM). A surrogate model application using static condensation and HROM techniques is proposed to show the possibility of solving multibody systems interfacing Kratos' ROM framework with Mathworks control capabilities in a fast and accurate way. The validation of the applied methodology is given by 3D complex models
