A colourful display of home plasticware is for sale near a tyre retreading plant in the Alem Bank area. Natural and synthetic rubber (Polymer) constitute the major components of the tyre manufacturing process. While Ethiopia's southwest is suitable for rubber plantations, most tyres are imported due to the lack of intermediate processing factories. Farmers have also not adopted the practice due to small land availability and inadequate training in agroforestry techniques. Thailand, one of the largest tyre-producing nations, has close to four million hectares of land covered in rubber plantations.
