“Are those… plastic cups up there?” Scorch said, looking at the roof of a bus stop, while chomping on a pizza slice she bought from a local restaurant in Naples, Italy.

“Yes, Scorch! You have to admit. Italians are creative!” Felix said. “It’s a great idea, isn’t it? Making bus stop roofs from discarded plastic cups. Let me give you a few examples of best out of waste efforts.

A house named Villa Welpeloo in Rotterdam, the Netherlands became the world’s first modern house in 2005 to be built majorly from waste construction material – about 60% of it. Architecture firm Superuse took steel from old textile machines, and wood from damaged industrial cable drums.

In 2013, architect Duncan Baker-Brown from the United Kingdom went one step further and built the Brighton Waste House from about 90% waste materials. Baker-Brown used a combination of old-but-gold materials, right from used denim and toothbrushes to plastic DVD cases and old bicycle tire parts.

In Mumbai, India, in 2015 the Collage House was built using 100-year-old stone columns, waste silvers, and other damaged construction materials.

An almost fairy-tale-like structure stands in Prince Edward Island, made from 25,000 white and green glass bottles, glued together with cement. It’s called Bottle Houses and it was built around 1980,” Felix said.

“It’s a great idea to reuse materials instead of constantly digging the earth for new raw material,” Orak said.

“Yes, Orak. Why let anything go to waste? Humans need to start recycling more and abandon the idea of ‘new’ stuff,” Felix said.
