The construction and demolition sectors are among the world’s most critical activities, generating large amounts of waste. Thus, these sectors’ waste accumulation problem is related to the environmental protection system and proper waste management. On the other hand, it is well known that proper waste disposal can increase its value. In this way, the economic potential of the trash can be raised again. Therefore, this article will examine the economic potential of construction and demolition (C & D) waste. Different waste management processes will be analyzed to better understand the topic from a financial perspective in this area underway in Spain. Therefore, data from other regions of Spain were collected. This data led to results where the most expensive rooms were Pais Vasco and the Balearic Islands, where disposal of C & D waste had the highest prices, exceeding EUR 30 per ton. Conversely, the lowest prices are found in regions such as Navarre and Andalusia, where prices per ton are EUR 8 and EUR 6, respectively. The values show a direct relationship between the treatment price and the amount of C & D waste disposed of. Therefore, this article will look at different factors influencing sustainable waste management. Such activities have a positive impact, as waste needs to be recycled and reevaluated by waste management operators. The cost of construction waste is an integral part of the budget because it represents the monetary value of the cost of collecting and recycling construction waste. Construction waste is an essential resource for economic and social development, as it contributes to job creation, education and culture, and the protection and preservation of the environment.

Urban mobility makes it possible to incorporate new perspectives that make it possible to question and problematize the way in which social links and relations between city dwellers are shaped. In this way, mobility constitutes an increasingly massive, recurrent, and complex social practice, strongly conditioned by the existing levels of inequality and particularly those that entail processes of social exclusion. In the present research, the efficiency of the modality of adapted public transportation for people with disabilities in the city of León, Guanajuato, Mexico, which came into operation in 2012, receiving the 2019 Building Equality Award from the International Center for the Promotion of Human Rights and United Nations Educational, Scientific and Cultural Organization (UNESCO), is analyzed. The management, design, and implementation of Inclusive Urban Transportation (TÜI), demonstrated how the articulation of actors (public, private, and civil society) are of vital importance for the success of the project. In this sense, it is important to count on the permanent participation of focus groups that identify and understand the real needs of users with reduced mobility. The results achieved allow establishing an evaluation that contributes to detect and mitigate the conditions of vulnerability, risk, and segregation of people with disabilities.

Intervenciones contemporáneas en territorios con historia es la cuarta publicación de la Colección Hábitat y Patrimonio que integra reflexiones sobre la interacción entre proyectos urbano-arquitectónicos y entornos patrimoniales, donde se evidencia crítica, teoría, praxis investigativa y puesta en valor del territorio y sus comunidades, como unidad y continuo histórico; adicionalmente, se involucra el tema de accesibilidad y comunicación incluyente como parte de realidades actuales y visiones integradoras del patrimonial cultural; pasado y presente se interpretan como estratos sucesivos cargados de historia en los territorios, donde cada época hereda lo relevante del patrimonio cultural material y lo significativo de lo inmaterial para el presente, cuyo compromiso no solo es con la actualidad sino con el futuro por legar a generaciones receptoras de memorias. Para evidenciar el rol contemporáneo en territorios cargados de historia, se conjugó conocimientos y experiencias de investigadores y profesionales especializados en áreas de la cultura, historia, urbanismo y arquitectura procedentes de Irán, Italia, España, Portugal, México, Guatemala, Brasil, Chile y Colombia, socializadas en las Cuartas Jornadas Internacionales de Reflexión en Patrimonio Cultural 2017, organizadas por la Universidad de La Salle y la Facultad Ciencias del Hábitat en Bogotá, Colombia. Se busca, entonces, generar escenarios para la reflexión a partir de realidades actuales, donde mucho está escrito y plasmado en obras materiales, evidenciando que la diversidad y las particularidades de los contextos ponen la pauta y, de alguna manera, condicionan la creación espacial actual, cuya responsabilidad no solo versa en la interacción entre períodos sino en la concreción de propuestas espaciales bajo criterios de calidad en la consolidación de contextos a través del diálogo entre mundos pasados y presentes
