Proceso de producción y gestión de los Residuos de Construcción y Demolición

Description

The process of production and management of Construction and Demolition Waste (C&D waste or CDW) is standardized and responds to a series of administrative steps, according to the law. The process is aimed at reducing C&D waste and its correct management and treatment, but sometimes results in inefficiencies arising from the bureaucratization of the evaluation of compliance with the requirements.

Sometimes, construction companies establish contractual commitments backed by guarantees (or other types of guarantees), related to the proper management of waste and compliance with the established management plan, so if said plan is based on an inaccurate estimation, contractual commitments are also affected.

This project focuses on the area of building, which generates different types and volumes of CDW. Specifically, in the study of vertical buildings, both administrative and residential buildings.

Objectives

  • Develop a set of knowledge based collaborative computational models.
  • These models allow joint evaluation of different C&D waste management alternatives, based on an accurate enough estimate of each type of generated waste.
  • Estimate is obtained from the ‘work units’, integrating existing variables and knowledge that affect the generation of C&D waste.
  • This project focuses on the area of building, which generates different types and volumes of C&D waste. Specifically, in the study of vertical buildings, both administrative and residential.

Actions

  • Estimation of the amount of waste. Mathematical models for estimating the amount of C&D waste that will be produced in a project, from the work units.
  • Estimation of the evolution of C&D waste over time. From the historical data of similar previous projects, the amount of waste that will be generated at each moment, throughout the duration of the work is determined.
  • Estimation of management costs. Minimize the cost and maximize the amount of segregated C&D waste.

Results

  • Set of computational models for the optimized management of C&D waste.
  • Design of management alternatives, focused on waste reduction and optimal segregation. The data comes from the actual execution of the work and not only from the measurements on plans, which reflects the influence of the construction process on the generation of waste.
  • More precise estimation of the waste to be generated during the course of a work, reducing the costs of both the waste management itself, and those other administrative costs due to the deviations between the estimates and the final results.
  • Platform that exploits the generated mathematical model. The tool generates different possibilities of waste management, which the company can assess and choose the most appropriate, allowing the analysis of different management options based on different criteria / restrictions.
