The construction industry accounts for a significant part of society’s consumption of raw materials and a large portion of Denmark’s total waste production and CO2 emissions. The demolition process, where building materials are removed, constitutes a crucial link in the circular value chain of construction.
Where the demolition process has traditionally been regarded as a source of large waste quantities without value, demolitions will in the future be the production site for valuable resources for construction. To better utilize the materials, it is necessary to increase focus on planning and executing the demolition process.
Methods for removing, sorting and handling hazardous substances already exist today, and the processes are known by demolition companies. But often inadequate planning, poor descriptions or a tight schedule prevent the utilization of good resources.
Summary
The guide is part of three interconnected guides from Værdibyg which also includes “Tendering of Demolition Projects” and “Environmental Surveying and Demolition”. The three guides provide recommendations on how demolition tasks in connection with new construction or renovation can be planned, tendered and executed with the greatest possible benefit for the environment, work environment and collaboration between the involved parties.
The guide contains:
- Instructions for planning circular demolition projects
- Methods for identification and handling of reusable materials
- Recommendations for collaboration between building owner, consultants and contractors
- Practical examples and cases from completed projects
- Proposals for stipulated services in demolition
- Good advice for reuse and recycling of building materials
Facts about this guide
The guide is published by Værdibyg with financial support from the organizations behind Værdibyg and Grundejernes Investeringsfond.
Who is the guide aimed at?
The guide is primarily aimed at building owners as well as client consultants, technical consultants, contractors and authorities. It may also be relevant for companies wishing to receive reusable materials – either to incorporate them directly into other construction or to resell them – as the guide provides insight into the process prior to delivery of the reusable materials.
What you get from the guide
By following the guide’s recommendations, you can contribute to promoting the circular economy in the construction industry through better utilization of material resources. You get tools to plan and implement demolition projects where reuse and recycling are given high priority. The guide helps you identify valuable materials early in the process and ensure they are handled correctly so their value is preserved.
Background
Traditionally, the demolition process has been regarded as a waste-producing activity without focus on the materials’ potential value. With increasing focus on sustainability and circular economy, there is a need to rethink the demolition process as a resource-producing activity. The challenge often lies in inadequate planning, insufficient descriptions in tender material and tight schedules, which prevent optimal utilization of materials. This guide addresses these challenges by providing concrete instructions on how demolition projects can be organized and executed with focus on resource utilization.
