Repurposed Canvas Import Companies List

We are a Spanish ****, and we are trying to develop a project to be developed in India. It involves making a piece of recycled textile to make a pavilion at the Ve****** in collaboration with an artist and an architect. We need to get used and discarded canvas that can withstand heat and rain, and then join them together to make a new one. We are looking for places in Andhra Pradesh or nearby where we can collect these discarded canvases, which can be awnings or those that cover trucks, or vinyl used in fairs and exhibitions, etc. We would be very grateful if you could give us information on where to get them. Thank you very much.
