A German architect has filed an application for a new type of cement made of dog poo.
Friedrich Lentze, 57, from Berlin, applied for a patent for his “odourless heating and building material” made from the dog poo cleaned from the streets of the German capital every day.
He said: “They thought I was joking at first, but it makes economic sense as the stuff has to be collected anyway, so why not use it for something useful. The loads of dog poo that are gathered every day actually make a great mortar with fantastic insulating properties.”
He added that dung had for centuries been used as building material and he had combined it with modern materials to come up with a new type of insulating cement.
