TLDR
In this article, the origins of waste, waste minimization design and construction practices in Greece and waste management are investigated, as well as the waste minimisation responsibilities regarding the profession of engineers.Abstract:
ABSTACT:The excavation, construction and demolition waste production in Greece is estimated at 50 million tonnes per year and it tends to increase. Hence, a Directive has been legislated recently to lay down measures to protect the environment and human health by reducing the adverse impacts of the waste production and management, using alternative methods. Additionally, this Directive, in concert with Directive 2008/98/EC of the European Parliament and the Council, aims by 2020 to increase the preparation for re-use, recycling and other material recovery methods of non-hazardous construction and demolition waste to a minimum of 70% by weight. In this paper, current literature and studies on engineers’ approach towards construction waste minimisation are reviewed. Furthermore, by means of a postal questionnaire, the origins of waste, waste minimisation design and construction practices in Greece and waste management are investigated, as well as the waste minimisation responsibilities regarding the profession of engineers. The study shows that waste generation on site is directly related to design process. Better site planning and supervision are believed to be the solution in on-site waste minimization. Legislation and financial rewards were found to be the major motivations that could influence the integration of waste minimization practices.read more

TL;DR: This paper presents the first Big Data based architecture for construction waste analytics, validated for exploratory analytics of 200,000 waste disposal records from 900 completed projects and revealed that existing waste management software classify the bulk of construction waste as mixed waste, which exposes poor waste data management.

Architects’ perspectives on construction waste reduction by design
TL;DR: Results indicate that a number of constraints, namely: lack of interest from clients; attitudes towards waste minimisation; and training all act as disincentives to a proactive and sustainable implementation of waste reduction strategies during the design process.

A model for quantifying construction waste in projects according to the European waste list.
TL;DR: A model which allows technicians to estimate C&D waste during the design stage in order to promote prevention and recovery and which would allow detection of the source of the waste and to adopt other alternative procedures which delete hazardous waste and reduce CW is presented.
