Apple has unveiled a new version of its MacBook Air laptop, this time made of recycled aluminium, as well as a new Mac Mini and an iPad Pro, all pricier than their predecessors.

Nearly 10 years after the launch of the first MacBook Air by the late Steve Jobs, his successor Tim Cook presented on Tuesday the latest version of this PC, just 1.56 cm thick, compared to 1.94 cm (0.75 inches).

This model was made with 100 percent recycled aluminium and recycled plastic, a change which reduces its carbon footprint, Apple said.

Last year Apple announced it would aim for a circular production system for its iPhones, which it said would allow for making new products with recycled materials.

The Mac Mini unveiled Tuesday – the latest version of Apple’s high performance mini desktop computer – is also manufactured with completely recycled aluminium and plastic as well.

Apple is not the only computer manufacturer to use such material, but a report by Greenpeace last year called it among the best performers in the industry in terms of going easy on the environment.

In its most basic model, with 128 gigabytes of memory, the MacBook Air will be available Nov 7 for $1,789.

The Mac Mini comes out on the same date for $1,179.

Apple also unveiled a new version of its iPad Pro tablet with a screen that looks nearly edge-to-edge and boasts a faster processor. It includes features from the latest iPhones.

Apple’s new iPad Pro pushes 11-inch and 12.9-inch displays to the edges of the tablet.

The changes are part of an effort to overhaul a product that has seen sliding sales in recent years.

Sales of iPads peaked in the first quarter of 2014 at 26 million units. By comparison the company sold about half that many last year in the final quarter.
