In a world where the population is expected to peak at around 9 billion people in the next 30 to 40nbspyears carefully managing our finite natural resources is becoming critical. We must abandon the outdated take make consume and dispose mentality and move toward a circular economy model for optimal resource efficiency. Products must be designed for reuse and remanufacturing which

Energy efficiency and recycling go hand in hand. Anyone who lived through the devastating hurricanes that struck Texas Florida and Puerto Rico last summer found out the hard way what its like to go without energy for several days or in the case of Puerto Ricans months.. Sitting in your home with no power no hot or running water and without the ability to cook food is a truly awful

The opposite of saving energy is wasting it. Toss an aluminum can into the trash instead of recycling it and the energy required to replace that discarded resource with new aluminum from bauxite ore is enough to keep a 100-watt incandescent light bulb burning for five hours or to power the average laptop computer for 11 hours according to the Container Recycling Institute

2012-4-15Re-melting and casting an existing metal is simply a lot easier than having to extract the metal from an ore. Even though separating joined and mixed materials poses a challenge for recycling the total energy requirement for recycling a ton of iron is some 20 lower than for mining and processing it

When steel scrap is processed in an electric arc furnace EAF about 1523 kg of dust are formed per tonne of steel which referring to steel production for 2012 translates to between 6.7 and 10.3 million tpa of EAF dust being produced. Table 9.2 provides a summary of the composition of EAF dust as well as other inc- and lead-containing residues
