Colombian car making industry is mainly composed of vehicle assembly firms, which usually performs painting, welding and joining operations by using CKD (Completely Knocked Down) which are exported and imported in parts and not in assembled units components. The production of materials and fabrication of parts take place mostly outside the country. Importing of the materials in Colombia which includes CKD components or imported vehicles are according to the new vehicles sold as per the amount and the types.
Consumption of Iron and steel are growing at a steady pace. In the case of waste material also, iron and steel are considered to be high and holds the largest share by 2020. Aluminum is also present in a limited amount. Glass FRP (Fibre-reinforced plastic) and carbon FRP are considered to be the material waste that is significant in lightweight scenarios and speculated to be in 2030. It remains close to zero in scenarios where conventional material is exceptional.
The iron and steel share in waste material is reduced due to the increment of aluminium, glass FRP and carbon FRP. As per the study conducted by J.C. Gonzalez Palencia et al./Energy, the sales in new vehicles are higher than the retirement of the vehicle as it resulted in a tendency to collect materials. In the light BEV and light FCHEV, there is a decrease in iron and steel stock by substituting with lightweight materials but in all scenarios, aluminium stock increases because of its higher usage and even in ZEVs with conventional vehicles. Also, there is a rise of stock in glass FRP and carbon FRP.
In passenger car stock, the materials which are contained is a potential feedstock for the production of secondary materials and can be enhanced by using improvised recycling techniques. In Colombia, the total sales of national assembled vehicle is round about 41% and the estimated energy demand for assembly of the vehicles and retirement of vehicle by 2050 is 2.4PJ/yr which is assumed to be less than 1% of total energy consumption for the vehicle in the same year. The value is excluded from the energy value which is required for secondary material produced from recycled materials. By 2050, the production energy reaches a value of 17.6PJ/year for the base scenario.
