Today an article in the Dutch Telegraaf was published about the first sustainable disco: Watt in Roterdam. This disco, following the 3P-principles (people, planet and party) gets a lot of atention for its green measurements taken. The floor is generating energy, the more the clients the dance, the more energy will be generated. Each area indicates the effect of their way of dancing. Other sustainable measurements are the use of rainwater and for example zero waste bars.
