M1 is designed to run tasks as efficiently as possible, delivering outstanding performance while using significantly less power. This change, along with our efforts to use recycled and low‑carbon materials, has decreased the carbon footprint of the new iMac by about 20% compared with the previous generation. 1.
· Based on the e-waste estimation generation from four IT products (in Fig. 10a), the major potential recoverable metals (in particular copper, gold, silver, platinum and palladium) in the e-waste were estimated by quantifying the amount of the printed circuit board (PCB) and the associated metals content (cumulative amounts as shown in Fig. 10b
· Informal treatment of e-waste plays an important role in many countries which have no or weak formal waste management structures. One of the challenges for assessing informal e-waste recycling technologies is to identify their disadvantages and potential technology improvement. The analysis of informal recycling processes starts with a balance of input and output materials for each of

With the concept of Internet-of-Things, autonomous vehicles can provide higher driving efficiency, traffic safety, and freedom for the driver to perform other tasks. This paper first covers enabling technology involving a vehicle moving out of parking, traveling on the road, and parking at the destination. The development of autonomous vehicles relies on the data collected for deployment in
· It also forecasts the recycling rate, the economy of resources and hazardous materials, and components that are difficult to recycle. Because of WEEE problems, a closed-circuit network model is proposed in Phuc et al. (2012) to the supply chain, considering the recycling process. Mixed-integer programming with fuzzy parameters is used in this

· Hydrogen & Fuel Cells. Fuel cells use the energy from hydrogen in a highly efficient way -- with only water and heat as byproducts. Primary energy sources take many forms, including nuclear energy, fossil energy -- like oil, coal and natural gas -- and renewable sources like wind, solar, geothermal and hydropower.
The introduction of Hybrid Power Systems with energy storage is, therefore, a new and attractive means for reducing both fuel consumption and exhaust emissions. The Wärtsilä system’s design handles the energy storage capabilities in the form of a battery pack, an hybrid control system, a power transfer system, and an energy storage system.

Wärtsilä’s shaft generator systems are designed with PWM frequency converters using modern IGBT technology. An additional synchronous compensator is no longer needed to generate the reactive power or the short circuit current, and is not required for the voltage control or for the filter circuits in order to lower the harmonics to admissible levels.

· The moisture of solid wastes ranged from 5% to 40% with an average of 20%. This very wide range of the MC depends on the socio-economic structure and the regional characteristics of the solid waste [75]. Nevertheless, the MC may reach up to 55%–70% depending the on climate conditions, and solid waste composition [76].
· E-waste is one of the fastest growing waste streams in the world in terms of volume and its environmental impact on the planet. The existence of precious metals in the e-waste stream provides a major economic benefit for recycling industries but due to the presence of hazardous chemicals, a proper recycling technique is required prior to the disposal of the e-waste.
