Siri's meet-cute with Apple's recycling robot goes horribly wrong in Earth Day ad.

Last month Apple unveiled a large-scale robot named Liam, a huge industrial robot with 29 freestanding robotic arms, which it had been secretly working on in a warehouse for years. Not surprisingly, the reveal left a lot of people with questions. How big is this thing? How does he disassemble your ruined, returned iPhones, so they’ll all be easier to recycle?

In the spirit of Earth Day, Siri wants to fill you in.

When you ask Siri about Liam, she'll quip one of a dozen or so lines, such as “Liam is my new robot colleague at Apple. I’ve asked him to coffee but he’s kind of a workaholic.”

Apple has also put together a promotional ad for Earth Day that highlights both Liam and Siri. Check it out above.

The move comes as Apple aims to draw more attention to its eco-forward efforts. In creating Liam, Apple is trying to address a growing problem for the consumer electronics industry. Electronics waste, particularly waste from batteries, is a growing hazard in developing nations, where much of this waste can ultimately wind up.

Liam is programmed to disassemble the many pieces of iPhones — such as SIM card trays, screws, batteries and cameras — by removing components bit by bit so they’ll all be easier to recycle. Traditional tech recycling methods involve a shredder with magnets that makes it hard to separate parts in a pure way (you’ll often get scrap materials commingled with other pieces).

Apple also recently pulled its existing iPhone return policies into one overarching program called Renew. It includes Apple's take-back initiative, where customers bring in devices to be recycled; Apple Care, which allows users to get new devices when their own is beyond repair; and the Apple trade-in program for those who want device upgrades.

For those who donate devices through its new Renew program toApple.com/Thanks, you'll be encouraged to download a collection of green-inspired smartphone wallpapers.
