Mottainai Kitchen is a culinary road movie, tackling the issue of food waste and other environmental issues in Japan, searching for sustainable solutions. The film follows filmmaker and food activist David Gross as he discovers the fascinating Japanese concept of Mottainai, meets local chefs, scientists and farmers while creating tasty recipes for a “Zero Waste Kitchen Revolution”. Dont waste anything that still has value.

Dont waste anything that still has value. This is the “Mottainai” concept. It can also refer to creative solutions. This ancient philosophy has been experiencing a revival in its country of origin, and it may offer some useful advice for the rest of the world too. Despite its fame as a gourmet haven, Japan has one of the highest numbers of food waste globally. How is that possible and what can we do about it? Where other people see only problems, Mottainai Kitchen goes out to find solutions.

Gross travels across Japan for 4 weeks and only cooks with ingredients that others call waste. On his journey he meets chefs, farmers, activists and scientists and is supported by Nikki, his translator and colleague. The two drive a mobile kitchen created by young designers using recycled materials. Mottainai Kitchen is a film that combines purpose and fun,whetting your appetite for a sustainable future.

People from all over the world meet on a weekly basis at the Atelier de conversation of the Bibliothèque publique d’information located in the Centre Pompidou in Paris to practice their French. Refugees of war sit together with businessmen, easy-going students next to victims of political persecution. As diverse as its members might be, they have one goal in common that connects all of them: to learn the language and find companions while living abroad – if not to survive living abroad. At this hopeful place social and cultural borders dissolve. People, who otherwise would never be in touch, meet eye to eye.

Dans la Bibliothèque publique d‘information, au Centre Pompidou de Paris, des personnes venant des quatre coins du monde se rencontrent, chaque semaine, dans l‘Atelier de conversation pour parler français. Les réfugiés de guerre côtoient les hommes d‘affaire, les étudiants insouciants croisent les victimes de persécutions politiques. Malgré leurs différences, participantes et participants partagent des objectifs communs : apprendre la langue et trouver des alliés pour pouvoir (sur)vivre à l‘étranger. C‘est dans ce lieu rempli d‘espoir où les frontières sociales et culturelles s‘effacent que des individus, dont les routes ne se seraient jamais croisées, se rencontrent d‘égal à égal.
