I thank the Chairman, Deputies and Senators on behalf of the Construction Industry Federation, CIF, for the opportunity to meet with the committee and address this important issue which could have major influence on construction in the future. I am here today with Mr. Eamonn Stapleton, managing director of Clonmel Enterprises and chairman of our environmental, social and governance, ESG, policy committee, and Mr. P.J. Ryan, head of ESG in the federation.
What is the circular economy? Ireland's Circular Economy and Miscellaneous Provisions Act 2022 defines a circular economy as a model where production and distribution processes of goods, products and materials are designed to minimise the consumption of raw materials; the delivery of services is designed to reduce the consumption of raw materials; goods, products and materials are kept in use for as long as possible; the maximum economic value is extracted from goods, products and materials; and goods, products and materials are recovered and regenerated at the end of their useful life. Circular economy concepts are nascent in construction compared to other sectors and to date, they have focused on waste prevention and management.
In relation to infrastructure development, Ireland's economy and population are expanding, but there is a shortfall in infrastructure that will impede future growth and potentially hinder our progress towards a net-zero economy. Ireland has not developed the same level of infrastructure as our European neighbours, which have established an impressive energy and transport system over the last century and are therefore better positioned to achieve their sustainability targets. The recent National Competitiveness and Productivity Council, NCPC, bulletin underscores this deficit - Ireland ranks 38th globally for basic infrastructure, including water infrastructure, the density of road and rail networks and particularly energy infrastructure, which results in higher electricity costs for industrial companies.
However, it is important to recognise that building infrastructure requires substantial quantities of virgin aggregates. The European Aggregates Association indicates that up to 20% of the current aggregate demand could eventually be met with recycled materials.
Additionally, much of Ireland's infrastructure is new, while some of our European neighbours have ageing infrastructure that can now be demolished, with the potential to recycle uncontaminated aggregates into new structures. The industry is concerned that drawing conclusions about Ireland's rate of construction circularity, the circularity gap, overlooks the underdeveloped state of our basic infrastructure and may penalise future development and growth. Any transition to net zero must be a just one.
On construction and demolition waste statistics, according to EPA data for 2021, construction and demolition waste forms the largest waste stream in Ireland, accounting for 51%, or 9 million tonnes, of the national total of 17.6 million tonnes. Notably, 85%, or 7.7 million tonnes, of construction and demolition waste is soil and stone. Thus, waste data is dominated by soil and stone. Most construction and demolition waste in Ireland was recovered by backfilling, at 85%, with 7% disposed of and 8% recycled. Regarding national decisions in Articles 27 and 28, the industry has worked with the EPA to develop national decisions on Article 27, dealing with by-products, and Article 28, relating to end-of-waste for recycled aggregates. These decisions aim to improve circularity by promoting recovery and reuse over disposal. The national greenfield soil and stone decision, which is anticipated soon, will delegate approval from the EPA to local authorities, streamlining the process and potentially allowing more brownfield material to be reused or recovered.
Regarding challenges in the new process, local authorities need time to adapt to their new roles and must be properly trained and resourced. Finding lawful receiving sites for greenfield soil and stone is challenging. Soil recovery facilities may need to adjust their licensing regimes, which could be time consuming. Timing is a major challenge, as materials can only be stockpiled on site for six months. An IT application to match donor and receiving sites and developing local depots for temporary storage could help mitigate these challenges.
On non-soil and stone construction and development waste, of the remaining 15% of construction and demolition waste, 45% comes from concrete, brick, tile and gypsum, with 27% being mixed construction and demolition waste. Introducing the waste recovery levy for mixed skips from 1 September is expected to increase the segregation of mixed-waste skips and reduce waste sent for recovery by incineration or use as solid recoverable fuel.
Regarding circularity in the concrete industry, the industry plans to collaborate with State agencies to allow crushed concrete to be reused as a secondary cementitious material, reducing the need for original Portland cement. This practice, which is common in most European countries, would enhance circularity and reduce greenhouse gas emissions in the concrete industry. The aggregate sector struggles with circularity due to the heavy weight of aggregates, making their transport over large distances cost-prohibitive. Additionally, the time mismatch between surface material availability and local construction project needs necessitates storage space, which is often lacking. To improve circularity, we urge local authorities to provide storage facilities and propose extending the permitted on-site storage time for soil and stone from six months to at least 24 months.
On measurement and reporting, the EU's corporate sustainability reporting directive, CSRD, will drive sustainability reporting, including reporting on environmental topics such as greenhouse gas emissions. The CIF has launched the CIF carbon calculator to help SME firms calculate their footprint and contribute to more robust data for tier 1 contractors' scope 3 emissions. The focus on measurement will increase awareness of embodied carbon emissions and uptake of products with environmental product declarations, EPD. As part of the CSRD, many CIF firms will need to report on resource use and circular economy under European sustainable reporting standard E5, driving greater awareness and behavioural change in procurement.
Regarding supply chain sustainability, understanding and being aware of evolving regulatory requirements throughout the supply chain will be essential for the industry to advance cohesively.
The CIF is proud to be a founding partner of the supply chain sustainability school, and we believe this free resource will assist firms of all sizes in embarking on their journey towards a more sustainable and circular future. Typically, 80% of contractors' greenhouse gas emissions are due to their subcontractors and suppliers.
Turning to key initiatives for the circular economy in construction, integrating circularity adds complexity and uncertainty to construction projects. Contractors must align their bids with detailed client specifications. Resource and waste management plans, material logistics, site layout, supply chain engagement and on-site training are essential. The industry supports developing a qualified resource manager qualification to champion resource efficiency.
Clients and design teams must make informed choices about construction methods, thereby encouraging contractor innovation. Processing materials on site is crucial for minimising the transportation of resources and waste. The permitting regime for mobile crushers on construction sites needs updating for flexibility to support circularity. A centralised online permitting system, standardised application procedure, clear guidance and a tiered permitting approach are recommended.
Regarding legislation and standards, primary legislation, regulations and construction standards must work together to support the reuse or recycling of all construction and demolition waste, effectively minimising landfill disposal. Clients must plan for this during the design and construction phases. This will foster a manufacturing ecosystem where all construction materials are reused or recycled. We caution against new legislative barriers, like the EU proposal to classify recycled aggregates as substances under the REACH regulation, which would impede reuse. Circularity is a priority, and such regulations should be carefully considered. The industry welcomes the revision of the construction product regulations to mandate the declaration of a product's environmental characteristics, contributing to the development of harmonised technical product specifications.
Moving to testing and certification, robust but balanced testing criteria for secondary construction products are needed and we recommend developing a suitably resourced national testing centre for new innovative products.
On grants and supports, grants from Enterprise Ireland and local enterprise offices should be accessible to the wider industry for sustainability initiatives and the development of sustainability action plans. Additionally, support should be available to provide extra training for local authority staff working on small-scale projects, thereby enhancing the skills of engineering staff who manage and design these projects.
In respect of the review of construction works management framework, this should be updated to embed circularity, with additional support for the Office of Government Procurement. This includes whole life-cycle costing, quality in contract awards, digitalisation and green public procurement. Government policies should be harmonised across all agencies to speed up the approval and certification of new recycling processes. The insurance industry must align with the construction sector to support using construction byproducts and innovative solutions, avoiding impacts on collateral warranties.
We urge the Government to support the construction circular economy by investing in a construction byproduct recycling industry and developing digital waste-tracking tools. Construction waste is a valuable resource and the industry is committed to becoming an integral part of the circular economy.
I thank the committee members for the opportunity to address them and we will answer whatever questions they may have.
