ELV Plastics Separation Systems Planned

Recycling plastics from scrap cars will become ever more important in Europe, as the recent legislation on end of life vehicles (ELVs) is implemented. The law prescribes that by 2015 at least 95 per cent (by weight) of an ELV must be recoverable. Multinational car manufacturers Daimler Chrysler believe that this will not be possible without improving existing plastics recovery techniques. Current processes separating plastics by different densities are not effective with plastics which have similar densities. Compounds and coating plastics have been landfilled or incinerated due to separation difficulties.
The company expects that the average car in 2005 will consist of 25 per cent plastic (compared to 15 per cent today). Daimler Chrysler and other companies are developing a new approach to recovery.
After the shredding process, plastics are pre-sorted with a sensor and two types are removed. The two fractions are separated using infrared spectrometers.
After detection, the automated system can also determine which plastics should be returned for materials recycling and which should be sent for energy recovery

Waste management poses challenges, but could unlock major environmental and economic gains

Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
