A new exhibition is looking at the environmental impact of plastic and how it can have new life as a "valuable" resource after it has been discarded.
The University of Hertfordshire's Plastic Matter includes a canopy of recycled bottles and a huge box of items found in the River Thames.
The curators hope the display will "provoke conversations and action".
One artist, Maria Arceo, said she wanted "to inspire people to change the way they look at plastic".
The exhibition, which runs at the Hatfield campus until April, displays installations, film and photography from eight artists, including the canopy of 1,600 plastic bottles filled with coloured water and a time lapse video of 9,273 plastic spoons and 3,091 rubber bands as they collapse and decay.
It looks at how quickly we use and dispose of this "problematic material", consider its polluting impact and how it can become "something more treasured", the university said.
Arceo's work, Neocide, features material collected from more than 40 beaches along the Thames displayed in layers.
She said that after being told 2,000-year-old leather shoes had been found in rivers she discovered plastic only breaks down when exposed to light or heat, so in deep water they will never degrade and then become part of future rock formations.
"In Neocide, I separated the plastic into colours to highlight the idea of [rock] strata and also I wanted to make it attractive, precious and to change people's idea of plastic as a cheap and disposable material," she said.
"By creating artworks... you can see it as a resource rather than just something you can dispose of."
