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.

The German patent office confirmed it had received the application but declined to comment on whether it had been approved.
