Gull powered Splore 2015, an eco-conscious music festival in the heart of prime New Zealand Dairy country. Trouble was, nobody knew Gull Biofuel from a bar of soap, let alone its eco credentials.
Biofuel is made with dairy waste. In other words, cows. So we created a full-size billboard at the festival gates, completely constructed from hay and 100% edible vegetable dye. Then we let our cows show everyone exactly how biofuel is made, returning the whole billboard back to nature.
That’s just about as green as you get.
