- Babies need special care. That's why almost all baby food comes in glass. Glass is clean, pure and recappable. But now there's something about glass that makes it more special to babies. Glass can be recycled, this bottle and that jar can be returned to a glass container plant, ground up and melted to make new glass bottles. That means we're conserving natural resources, solving solid waste problems and making this country a little nicer for a little guy to grow up in.
