Stuart Studio: a champagne bottle's second act, hand-cut in Lille

Stuart Studio is a small Lille workshop where design, ingenuity and a real concern for waste all sit at the same table. Its best-known piece begins somewhere unexpected: an empty champagne bottle, collected from the city's bars.

Each bottle is hand-cut into a glass reservoir that quietly waters a plant for weeks at a time - forgiving of holidays and questionable green thumbs alike. The top is 3D-printed from a corn-starch bio-material, giving soft, modern lines and, thanks to local recycling and eco-printing, a footprint close to carbon-neutral. No two are the same, by definition.

The same thinking runs through the rest: two-tier snack bowls that hold the pistachios up top and swallow the shells below, keeping the table civilised without anyone having to think about it.

Last night's bottle, this season's planter.
