Sammanfattning
The construction sector is responsible for over one-third of the world’s total
greenhouse gas emissions, and a significant part of these emissions come from building
materials. To reduce these emissions, the construction sector needs to move towards
a circular material flow where reuse of building materials is prioritised. Procurement
plays an important role in a project’s structure and focus areas, and can be
used as a tool to increase the use of reuse. The aim of this study was to investigate
how reuse requirements in public and private procurement can promote the use of
reused materials and products, and to identify barriers and opportunities for the
application of reuse requirements. Through a literature study and interviews with
actors in the construction sector, the knowledge and experience on the subject have
been compared and analysed. The study shows that there is a significant lack of
knowledge about how reuse requirements can be formulated and used in practice.
There are several barriers to the implementation of reuse, such as guarantee issues,
laws and regulations, and an uncertain reuse market. To increase the implementation
of reuse, actors need to have the courage to set up reuse requirements, share
their experiences with others and develop new working methods that promote reuse.
In addition, governing institutions need to publish clear guidelines on how reuse can
be implemented, provide examples of formulations that can be used in procurement
and contribute with financial support to increase knowledge so that more reuse
projects can be implemented. As a step towards development, the authors have,
after requests from actors in the construction industry, compiled a compendium with
examples of requirements linked to reuse, which can be used as inspiration for future
procurements.
