Give me energy

I have been so incredibly lazy these last few days that I did not even had the energy to take photos. But it had to change as I have to go back to work tomorrrow. So I went on a bus journey to take a photo of this recycling plant. I kept on seeing it when coming from Stanstead airport into town and have been curious about it ever since.
It is the largest plant of its type in London. Waste gets turned into enough energy for 66.000 households.
