Construction & Demolition Waste Highlights from 2024
7.9 million tonnes generated
Construction and demolition waste decreased in 2024 from 9.0 million tonnes in 2023.
77% soil and stones
The dominant type of construction and demolition waste in Ireland is soils and stones.
Achieved EU recovery target
Ireland surpassed the European recovery target of 70% by backfilling or recycling 81% of it's non-hazardous C&D waste, excluding soil and stones.
73% backfilling
Soil and stones make up most of the C&D waste generated, which is reflected in backfilling being the dominant treatment type.
Metal waste is nearly 100% recycled
Nearly 400,000 tonnes of metal was recovered from construction and demolition waste in 2024 and recycled into secondary raw materials.
5% export
The majority of Ireland's construction and demolition waste is treated here in Ireland (95%). Most of the remaining 5% is metal exported for recycling.
This page contains Ireland’s construction and demolition waste statistics from the year 2024 (released June 2026). A subset of this information was submitted to the EU for reporting requirements under Waste Framework Directive (WFD) and is subject to Eurostat validation.

Generation
The C&D sector in Ireland generated 7,852,393 tonnes of waste in 2024, down from 9,042,402 tonnes in 2023.

Treatment
Most final treatment of C&D waste in 2024 took place in Ireland (95%) and only 5% was exported abroad for final treatment. Most of the exports are metal waste sent for recycling. There are also significant tonnages of exported waste used for recycled aggregates.
Backfilling is the most significant treatment of C&D waste. The prominence of backfilling as a final treatment operation reflects the high tonnages of waste soil and stones in the C&D waste stream.
Metal C&D wastes are nearly 100% recycled and segregated wood, paper, glass and plastic have a recycling rate of 88%.

By-products and End-of-Waste
The EPA’s National By-product criteria provide rules for the safe reuse of greenfield soil and stones and prevents it becoming a waste. In 2024, 201 by-product notifications were assessed by the EPA and 1,999,332 tonnes of soil and stones were determined as by-products.
The EPA’s National End-of-Waste criteria for recycled aggregates can support the recycling of construction and demolition waste. This in turn diverts waste from landfill disposal, keeping it in the economy as a resource, which can reduce the environmental impacts arising from waste management.
Preventing waste and promoting reuse are integral to the circular economy. While this applies to all economic sectors, it is particularly relevant for the construction sector which handles large volumes of natural resources, such as soil and stones. Successful implementation of circular economy measures, such as the by-product regulation and end-of-waste criteria in this sector could lead to millions of tonnes of resources beneficially reused or diverted from the waste management system every year.
More Information
Construction and demolition (C&D) waste includes all the waste produced by the construction and demolition of buildings and road infrastructure. It contains a wide variety of materials such as: metal waste, segregated wood, glass & plastic, brick, tile & gypsum, bituminous mixtures, mixed C&D waste, soil, stones & dredging spoil, and C&D waste treatment residues .
C&D waste has consistently been the largest waste stream in Ireland in terms of both volume and weight and accounts for more than a third of all waste generated in the EU.
Construction and Demolition waste generation has remained relatively stable since 2019, moving between approximately 8 and 9 million tonnes from year to year. Annual tonnage generated is related to factors such as the type of development (housing, commercial, infrastructure) each year, and the stage of construction of developments with significant excavation works. By-product (Regulation 27) and End of Waste (Art. 28) may also affect the total generation of construction and demolition waste in Ireland.
EPA estimates of C&D waste generated and treated are based on different datasets. Waste collectors record waste as it enters the waste treatment network (generated), whereas the final treatment data indicate what happens to waste at the end of its journey through the waste treatment network (treatment). This can lead to differences in waste classifications and quantities. Notwithstanding this, following EPA data validation, there was < 1% difference overall between the tonnages of C&D waste collected and finally treated in 2024, providing a high level of confidence in the C&D waste statistics for 2024.
The separation of C&D materials, either at worksites or at waste facilities, is the necessary first step for recycling or other recovery of this waste. Recycling rates for C&D waste can be improved by enhanced segregation of C&D waste into individual material streams, either at source or at waste processing facilities. For more information on C&D waste prevention and best practice circular construction activities, see EPA’s Best Practice Guidelines for the Preparation of Resource & Waste Management Plans for Construction & Demolition Projects.
