Title 1: Barriers to Building and Construction Waste Reduction, Reuse and Recycling: A Case
Study of the Austrian Region
Author (s): Patrick Zou, Robyn Hardy and Rebecca Yang
Year of publication: 2015
To identify the types of scale for recyclable materials generated in residential
construction, renovation and demolition
To identify viable reuse and recycling methods.
To identify the risks, barriers and opportunities in the recycling or reuse process
To investigate possible strategies that facilitate material recycling, reuse and reduction
Study Methods: Desktop study, Focus groups, interviews and surveys
Most people in the building and construction industry disregard the potential resource of
Construction and demolition materials.
Australian State Government regulations are seen to work against C&D material
There are insufficient and inconvenience of recycling facilities increases haulage costs
and leading to loss of excavate natural materials.
Conclusions: There are significant barriers to reuse and recycling of C&D waste products in the
Australian Region Capital. Additionally, government policy is seen as a major contributor to lack
of proper recycling facilities for recycling and reuse of these materials.
Title 2: Barriers and Motivations for Construction Waste Reduction Practices in Costa Rica
Author (s): Lilliana Abarca-Guerrero, Ger Maas and Hijmen van Twillert
Study Method: Empirical study
Finding: The following factors act as barriers in the implementation of construction waste
strategies in Costa Rica. These include; Financial or Economic, Institutional, Environmental,
Technical, Socio-cultural and Legal factors.
There exists barriers and lack of motivation in the construction sector in Costa Rica creating
multiple inefficiencies in the reduction of waste construction materials. Additionally, the study
identifies that the construction price compared to the environmental cost as well as the belief
that waste reduction will never be sufficient are seen as major barriers. The comparison made to
other countries such as China, Chile and Thailand show a common trend in the building and
construction sector as pertains to C&D waste management.
Title 3: Concepts for Reuse and Recycling of Construction and Demolition Waste
Author (s): Patrick J. Dolan, Richard G. Lampo and Jacqueline C. Dearborn.
To develop concepts viable in the reutilization of construction materials.
The study identifies primary opportunities, constraints and means to divert construction
and demolition debris as well as other solid wastes.
Additionally, to evaluate the C&D material recycling and reuse technologies
To identify construction and building materials that can be salvaged for reprocessing or
recycling or reuse.
Study Method: Review of literature
Finding: Concepts for reutilization of construction materials such as material removal, debris
handling, quantity estimation, salvage and recycling potential and recycling and reuse of C& D
materials can be applied to minimize wastage of construction and demolition materials.
Project managers should be charged with organizing a construction recycling program for
every contact they handle.
There is a possibility to salvage construction and demolition components for reuse.
Primary constraints or barriers to construction and demolition, waste reduction, reuse and
recycling include; the inconsistent nature of the waste salvages, availability of equipment,
