In most cases, yes. The charity shop where I volunteer is part of an urban farm. We don't have a budget for new tubes (we rely totally on donations), so we patch tubes whenever possible. When it is not possible, we send the derelict tubes to the farm, where they use them to provide support for various crops, e.g. branches on fruit trees, etc.
