Sony Ericcson bolstered its green credentials earlier today, introducing two new phones made from old CD cases and water bottles. The GreenHeart C901 (top left) and Naite (top right) have all the features you’d expect on a new release (camera, video streaming, bluetooth,…) but are made from at least 50% recycled plastic and colored with “eco-friendly” water-based paints. The company claims that “thanks to these innovations, the overall CO_² footprint over the full life of the C901 GreenHeart™ and Naite is reduced by 15%.”

Both phones come with a low-power charger and an in-phone e-manual which reduces paper usage by 90 per cent and are part of the company’s GreenHeart™ program, aimed at elimating the use of hazardous chemicals from the product design and manufacturing process.

Both new GreenHeart™ phones build on Sony Ericsson’s industry leading ‘green core’, the result of a long standing commitment to eliminate the use of hazardous chemicals from the product design and manufacturing process..

In earlier posts, we’ve profiled efforts by other phone makers to green their products. Earlier this year, Samsung released it Blue Earth phone, and Motorola put out its MOTO W233 Renew. As Sony Ericcson pointed out, given the volume of products moved each year, the industry needs to tackle the issue of waste and efficiency. More than 1 billion phones are sold globally each year, along with boxes and other materials.

In yesterday’s post, we reviewed the “old school meets new school” qualities of the Baylis Eco-Media Player, a pretty sweet little green gadget. Just wind it up for a minute and the on-board generator will power the player (MP3, movie, photos, flash light, radio…) for 45 minutes. Today’s post is more “new school meets new schools,” as we hear news that Energizer has partnered with XPAL Power to create a compelling line of portable charging solutions for a variety of devices. As Darren Murph writes in his piece for Engadget, “the rechargeable power packs and emergency chargers — over ten of ‘em in all — will all ship by July of 2009 and will include devices for PMPs, PNDs, portable DVD players, netbooks and digicams.”
