Japan report: what's happening in Green technology

Of the many huge Japanese electronics purveyors that we've long been familiar with, one name that rarely stands out from the pack is that of Sanyo.

The Osaka firm has a portfolio as broad as most of its rivals, but rarely makes the headlines – something that's set to change soon as something of a revolution turns the company on its head and changes its very way of doing business.

Green technology

Most Sanyo brochures prominently display the current 'Think Gaia' slogan – an eco-tinged theme that has been used since 2005 in Japan. Sanyo Japan's Aaron Fowles explains why the company has taken this to heart:

"British geophysicist James Lovelock introduced the Gaia hypothesis in the early 1970s, envisioning the earth as 'an active, adaptive control system able to maintain the Earth in homeostasis'".

"Based on this harmony and interdependence, walls were broken down between companies and divisions - our office literally has no walls around each division or team," he says.

This, of course, had a purpose, with Sanyo divisions sharing ideas with each other in a way that hadn't happened previously. A perfect example of this resulted in one of the company's flagship products.

Green machines

After some time spent looking for a commercial application for its new water recycling and purification technology, one internal Sanyo division realised it might just work in the products of another section.

The upshot was the Aqua range of high-tech washing machines. One aspect of the new machines – which are marketed to shoppers in terms of how much they can save on a year's water bills – is the Aqua Loop water-saving technology that uses 96 per cent less water than an equivalent Sanyo washer from the late 1990s.

That's interesting enough, as is the claimed annual saving of around £70 per household, but another breakthrough is altogether more surprising.

The Air Wash 3.0 system creates ozone that washes away bacteria, dirt and smells, meaning even dry-clean-only items can be washed at home.

Green batteries?

After the lean, green washing machines Sanyo's new approach dealt it an even bigger hit in the shape of the eneloop-brand rechargeable batteries that are already a monster hit (50 million +) and which are soon to be bundled with a "very high-profile gaming device", if rumours from outside Sanyo are to be believed.

Fowles explains the eneloop evolution: "In a review of the reason that people don't buy rechargeable batteries, it was found that the biggest factor was the inconvenience of not coming pre-charged.

"[Add in] the fact that they had a horrible self-discharge rate, and you could never trust rechargeables in sensitive devices like your alarm clock," he says.

Solar power

We could list plenty more products like those that all clearly rise well above the usual green rhetoric employed by many rivals, as well as large-scale PR endeavours like the giant Solar Ark solar power plant and museum that rises above the Bullet Train tracks in central Japan, but is this part of covert Sanyo move upmarket and away from its roots?

Fowles responds positively: "The emphasis on products that support the Think Gaia brand vision is, in a sense, a rebranding. It is not a move away from large-scale manufacturing by any means, but instead acts as a guiding voice as it advises [us] to conserve resources as much as possible and create new innovative technologies that can offset the carbon footprint left by manufacturing them."

That's all very well, but let's not forget that Sanyo still does huge amounts of business on its electronics lines, including Xacti digital cameras and camcorders. Unsurprisingly, Sanyo has an answer to the charge that those things hardly encourage the green lifestyle.

"The opposite of Think Gaia would be the blind pursuit of convenience and comfort, [but there is] another path - to be a wise and aware manufacturer by focusing efforts on lessening the environmental impact these types of products have."

He continues: "A small example is our Xacti digital movie camera. They used to be CCD, but we switched recently to CMOS, which means that you can use the battery for a little longer than CCD. This was made possible by advancements in CMOS, which has finally caught up with CCD."

Still, it's all about consumption at the end of the day, isn't it? "Sure, we can live life without digital cameras, but it is more fun to make memories," says a rather candid Fowles.

Recycling water

Returning to the surprisingly iconic washing machine that turns out to symbolise much of what this new, improved Sanyo is all about, Fowles explains:

"By making a washing machine that can reuse bathwater and recycle it in Japan, customers not only save on their water bills, but they save water that needs to be used for drinking - that type of water makes up less than 1 per cent of the Earth's water supply.

"The balance is found in making products that will eventually offset the company's own emissions and use of natural resources, benefitting both the company itself and those that use those products."

While washing a pile of laundry with ozone and just a dribble of bathwater or making incremental changes in the amount of energy we burn through by changing batteries or buying certain gadgets might not sound like a big deal, it's interested nonetheless to see what can be achieved within current technology lifestyles. Whether it's enough, is the question.
