Devenish Roof Tile
Technical purpose of product or process This LCA is carried out for Mannok Rooftile Devenish. The constituent raw materials of the tile comprise water, sands, cement (CEM I), admixture (superplasticiser), pigments and paint. These materials are used in the full range of products. Additionally, the roof ridge tiles also use an efflorescence suppressor, not used in the roof tiles. The roof tiles and ridge tiles are used in roofing in domestic and commercial housing. Mannok concrete roofing tiles are manufactured to BS EN 490 – Concrete roofing tiles and fittings – Product Specifications. The tiles are manufactured in two plants, located on the same site at Derrylinn, Co. Fermanagh. The raw mate- rials (sand, cement (CEM I), water admixtures and pigments) are batched and mixed and fed into an extrusion compartment. Here the extruded tiles are fed out onto aluminium moulds and sliced into individual tiles with a cutting knife. Perforation marks for nails are also made at this point. Then the tiles are placed into the rotary curing chamber in tall racks where they remain for 24 hours. This gives the tiles adequate strength to allow de-palleting and packing. In the de-palleting stage, the cured tiles are removed from the aluminium pallets with cutting blades. They then move into the painting booth, where they receive an acrylic coating, depending on the colour of the tile. Following this the tiles go into the drying chamber. Once dry, 6 straps of tiles are po- sitioned on a pallet with a gripping machine to form a full bale. All pallets are then hood wrapped and trans- ferred to yard storage via forklift for the 28-day curing process. The curing chambers are heated by kerosene and have electrically-driven fans to circulate the warm air. No differentiation is made in terms of energy used per declared unit of tile in the different curing chambers in the old and the new plant, as there is not sufficient detail on usage to do so. Similarly, no differentiation is made in electricity usage between the same processes in the different plants, for the same reason.
General comment on data set 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 doc- umented in the LCA report. In addition, to facilitate the reproducibility of this 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 Mannok Rooftiles EcoChain account.

Technology description including background system A1. Raw materials supply This module considers the extraction and processing of all raw materials and energy which occur upstream to the Mannok lite blocks manufacturing process, as well as waste processing up to the end-of waste state. A2. Transport of raw materials to manufacturer This includes the transport distance of the raw materials to the manufacturing facility via road, boat and/or train. A3. Manufacturing This module covers the manufacturing of Mannok Rooftiles and includes all processes linked to production such as extrusion, mixing, packing and internal transportation. Use of electricity, fuels and auxiliary materials in fiber production is taken into account as well.
