In a glasgow museum are two pieces of planking from a wreck submerged on the west coast of scotland for over 18 years : one , of teak , is almost entirely eaten away : the other , greenheart , is slightly pitted on the surface .
Sony ericsson , another handset-maker , recently announced a project called greenheart , which proposes various things the company would like to include in future devices , such as bioplastics and recycled materials , a low-power charger and online rather than paper-based user manuals .
