Production

Manufacturing On site Manufacturing Processes include Extrusion and Surface treatment (Powder coating or anodising).The Extrusion Process involves Billet Log Preparation, Billet Loading, Billet Pre-heating, Die Loading, Extrusions, Cooling, Stretching, Inspection, Cutting and Ageing. Powder Coating involves Pretreatment, Powder Spraying, Curing and Quality Checking. Anodising involves Pretreatment, Anodising, Colouring, Sealing, and Quality checking. The post-consumer recycled content of the product is 49.

Packaging Packaging involves standard techniques for packaging and container loading of aluminium profiles which aims at protecting the profiles till their use by the customer. Aluminium profiles are packed in bundles and clubbed together to form crates in accordance with the logistics requirements of global export markets.

EHS Gulf Extrusions is ISO 14001:2004 certified. The guidelines maintained at Gulf Extrusions are: to establish frameworks for HSE management systems, to Contribute towards the protection of workers from hazards and to eliminate work related injuries, ill health, diseases, incidents and contribute to the protection of the environment from hazards. No further health protection measures beyond the regulated measures for manufacturing firms are necessary during the production process.

Installation

Installation description

There are no considerable impacts associated with the installation of the material at the project site.

Packaging The paper used in packaging of aluminium profiles can be recycled, and wood used for making crated can be supplied back to us if in usable state.

EHS There are no health or environment related issues with respect to installation..

Use

Operation No operation impacts, only if the material is being fabricated at the project site, care is to be taken to collect all the waste such as aluminium chips, etc and dispose it as per standard norms.

Maintenance There are no impacts with respect to maintenance of the aluminium extrusions. Only routine cleaning and maintenance is sufficient to preserve the metal. The surface of aluminium can be treated in various ways to protect and enhance its appearance, cleaning with solvents such as water, water with mild soap or detergent, kerosene, turpentine, wax based polish, abrasive wax. After applying these cleaning agents, it is suggested to wash the surface of aluminium thoroughly

and dry with clean cloth to prevent streaking.

Service Life For aluminium the surface life is more than 25 years

EHS No environment, health and safety issues are associated with use of the extruded aluminium.

End of Life

Deconstruction It depends, as the collection scenario may vary from user to user. Considering an example of MASDAR City program, it sets a target collection rate to 100 %/.

Re-Use The complete material can be reused for the same or any other applcation needs, but it has to go through a recycling phase, and then brought back to use.

Recycling 100 % of the material can be recycled, once the metal has finished its end of life, then the metal is either transported to a smelter or a refiner for recycling.

Disposal Care should be taken to prevent disposing off aluminium to landfills. The best way to dispose material which has finished its End of life is to recycle it back and bring it in use.

System Boundaries &

Scenarios

The system includes cradle-to-customer production. A recycling EoL scenario of 100% recycling rate was used. All processes, from the extraction of raw materials, through product manufacture and delivery to were included, including the recycling of aluminium and a credit for the avoided production of primary aluminium at end of life.

Data Quality The age of the background LCA data is less than 8 years. Foreground data comes directly from Gulf Extrusions, and is compliant with ISO 14040-44 data practices. In addition, data was quality checked against standard extrusion process data for plausability.

Methodological Principles

Allocation procedures in the background data follow the ISO 14040-44 requirements. In the foreground model, mass allocation was used to allocate between the aluminium product and scrap, including both sold and remelted scrap. The recycling potential was calculated according to the requirement of the PCR document.

EoL credits End of Life credits reflect the avoided production of primary aluminium in subsequent life cycles. The credit is dependent on the quantity of recycled aluminium, based on a recycling rate of 100%.

GWP: Global Warming Potential; Energy nR: energy from non-renewable resources; Energy R: energy from renewable sources; ODP: Ozone Depletion Potential; AP: Acidification Potential; EP: Eutrification Potential; POCP: Photochemical Ozone Creation Potential. All process stages excluding the end-of-life credits add up to 100% of each of the burdens.

Interpretation

The main impact in the life cycle of the extruded aluminium profile is from the input of aluminium billet. Within the manufacturing process, the main impact arises from the energy use during extrusion. The transport of raw materials to the production site, and the transport of the finished product to , have a small impact on the total results.The cradle-to-gate energy consumption of the extruded profile is 1.4254E005 MJ. Over the whole life cycle (cradle-to-grave) this is reduced to 76948 MJ, due to the credit for avoided production at End-of-Life. Correspondingly, the total global warming potential of the extruded profile over its life cycle is 5959.6 kg CO2 eq.
