Alcoa's Wagerup refinery Alcoa's Wagerup refinery in the south west of Western Australia was commissioned in 1984 and today produces around 2.6 million tonnes of alumina per annum. The Wagerup refinery employs 630 people, more than 85% of whom live in the local region.
Alcoa has partnered Alinta Limited Alcoa has partnered Alinta Limited to develop cogeneration plants at our refineries in Western Australia. A year's electricity from each cogeneration unit saves around 450,000 tonnes of greenhouse gas emissions compared to a similar sized coal fired plant - equivalent to taking 112,000 cars off the road.
The Portland Aluminium smelter The Portland Aluminium smelter in south west Victoria is known as the 'Smelter in the Park' and recognised worldwide as a benchmark for industrial and environmental harmony.
Reducing vehicle weight In all areas of transport aluminium is reducing fuel consumption and greenhouse emissions by reducing vehicle weight. An aluminium component is 40-50% lighter than an equivalent steel component and every 10% reduction in weight produces a 6-8% reduction in fuel consumption.

A conveyor carries bauxite A conveyor carries bauxite from the Huntly mine throughthe Darling Range in Western Australia to the Pinjarra alumina refinery.
The Pinjarra alumina refinery The Pinjarra alumina refinery is located 86km south of Perth at the foot of the Darling Scarp. The refinery provides employment for more than 1100 people, more than 65% of whom have worked with Alcoa for 10 years or more.
Pinjarra refinery Pinjarra refinery has a production capacity of about 4.2 million tonnes per year, making it one of the world's biggest alumina refinery.
Following the refining process Following the refining process, alumina is shipped from dedicated port facilities at Kwinana and Bunbury to Alcoa's smelters in Victoria and overseas customers.
Rehab By 2001, rehabilitation is becoming difficult to distinguish from the surrounding forest.
A lightweight metal that is endlessly recyclable As a lightweight metal that is endlessly recyclable, aluminium plays a key role in our everyday lives. Aluminium is used in everything from light bulbs and TV antennae to boats , cars and space shuttles. One tonne of aluminium could make more than 60,000 soft drink cans or the frames for seven full size cars.

Alcoa scientists monitor Alcoa environmental scientists monitor a rehabilitated mined area at Huntly. Alcoa was the first company to return 100% species diversity in mined areas.
Successful rehab of mined areas Today visitors to Alcoa's mining operations in the south west of Western Australia can view successfully rehabilitated mined areas from a spectacular lookout point.
Alcoa's Kwinana refinery Alcoa's Kwinana refinery has been a major contributor to Western Australia since 1963. Around 2.2 million tonnes of alumina are produced at the refinery each year - enough to make 15,000 jumbo jets or 74 billion recyclable drink cans.
Portland Smelter Portland Smelter has a rated capacity of 358,000 tonnes of aluminium per year and is the region’s largest employer of some 700 direct employees and contractors.
Aluminium is endlessly recyclable Aluminium is endlessly recyclable and two thirds of the aluminium produced since 1886 is still in use today. In Australia Alcoa recycles around half a billion aluminium cans each year. Recycling only uses 5% of the energy needed to make new metal.
