Clima Pave 60mm Curragh Gold

Data flows have been modeled as realistically as possible. Data quality assessment is based on the principle that the primary data used for processes occurring at the production site is selected in the first instance. Where this is not available, other reference data is selected from appropriate sources. The dataset is representative for the production processes used in 2017. The process descriptions and quantities in this study are reproducible in accordance to the reference standards that have been used. The references of all sources, both primary and public sources and literature, have been documented in the LCA report. In addition, to facilitate the reproducibility of the LCA, a full set of data records has been generated which can be accessed via the EcoChain tool. This data portfolio contains a summary of all the data used in this LCA, and correspondingly, in the Kilsaran EcoChain account.

Detailed process description Waste The production site does not have any direct dangerous waste streams. All the Cut-offs and rejects wastes are generated from the paving production process. During the exiting process from the curing chamber, the products will pass a quality control operator who will remove all product deemed unsuitable for the open market and reject it. This rejected product will then be brought to an on-site crusher in a skip by forklift. Moving the rejected product straight to the crusher ensures the product does not get contaminated. (all rejected products are crushed and recycled) All concrete waste will enter this crusher and be crushed to a 0/8mm stone/dust. This recycled stone/dust is then brought by a loading shovel and placed into a discharging hopper where it will be recycled back into the recipes. It is only used for thru mix and back mix recipes. Some pallets are damaged or broken and are segregated into wood waste bin & recycled off site by an external waste company. Plastic packaging from minor raw materials like colourants, additives etc, such as containers and bags are sorted and recycled off-site by an external waste company. Pallets Product environmental impact is calculated without the use of pallets. To check whether pallets are of non- significant contribution to the overall environmental impact, a calculation has been made. A pallet can carry 1309 kg of product. The check has been carried out on a the Slane 50mm Curragh Gold. 1m2 of this type of paving weights 112 kg. So, it would use 0.085 pallet per m2. The Slane 50mm Curragh Gold record has been duplicated and in the composition, 0.085 unit of EURO pallets was added. The effect on the GWP for the materials was 17 grams of CO2 and thus only 0.18% higher than the materials without pallet. Compared to the whole product, including process and transport, it was only 0.07% higher. The effect on Abiotic depletion of fossil and non-fossil resources has also been checked for and found not to be significant. Therefore, it is not necessary to include the pallets in the compositions of the product. The EPD will clearly list the omission of the pallet material.

The LCA underlying this EPD is carried out for Kilsaran International. The LCA is carried out for the “Newgrange Paving Block 80mm Silver Granite” paving product. This product is selected as the most widely produced paving type. This EPD presents the results for Kilsaran paving products. The full list of Kilsaran paving products comprises out of 112 unique paving products. This EPD displays 3 of those unique paving products, as a selection, carried out by Kilsaran. The LCA and EPD of all other unique paving products can be sent upon request. The constituent raw materials of the paving products are EN 197 cements, gravel, sands, water, pigments and admixtures for mixing and efflorescence prevention. These materials are used in the full range of products. The paving products are used in large-scale paving project and in small-scale domestic paving projects by professionals and private consumers. (see for more information https://www.kilsaran.ie/products/paving/) The paving product consists of two layers: a bottom layer and a top layer. The layers are also referred to as the “Base layer” and “Face layer”. The products are produced according to standard BS EN 1338:2003 Product suitable for both pedestrian, vehicular use and commercial traffic when installed in conjunction with the correct, site specific sub-base design. Materials used for packaging, such as cardboard, paper shrouds, wood for crating and battens, and strapping, are left outside of the LCA calculation as these counted for less then 1% of environmental impact cut off criteria. The paving products are manufactured in a production plant, located at Piercetown, Dunboyne, Co. Meath. Raw material are transported to manufacturing facility in Piercetown Dunboyne. Paving operators select a recipe and the discharging hoppers will discharge the correct selected weight of material. Once mixed, the material will be lowered into a casting mould and will be hydraulically pressed into its desired shape. Products are cured for minimum 24 hours. Once cured the product will be stacked automatically onto pallets for storage or delivery. Product will pass a quality control operator who will remove all product deemed unsuitable for the open market and classed as waste. Products deemed unsuitable will be brought to an onsite crusher. (all rejected products are crushed and recycled back into the recipes.
