Empty drinks cans are to be transformed into forests of trees in a new recycling project.
Trees will include oak, ash, rowan, hazel, field maple and Scots pine
A tree will be planted for every tonne of aluminium collected until next June by six local authorities in Oxfordshire.
The recycling company Alupro expects to plant more than 35,000 trees in parks, woods and private gardens in return for cans, tin foil and other aluminium waste.
County Councillor Anne Purse said: "Any organisation that recycles over a tonne of aluminium cans and foil within the year can collect a tree.
"The trees can then either be planted locally or they can be donated to the Woodland Trust, which will then organise the planting.
"It is such a great idea to encourage people to recycle."
Trees planted will be species which are native to the UK, including oak, ash, rowan, hazel, field maple and Scots pine.
The two-year-old saplings will be planted next autumn.
