One of the main pillars of the modern industry is the uninterrupted supply of energy with a reasonable price. The energy production is based mostly on non-renewable energy resources that are getting more expensive progressively. This increase in energy cost consequently leads the companies to a more expensive production of goods. Therefore it has been established that energy efficiency is not only very important for the environment but also for the sustainable production in the manufacturing companies. Effective energy management plays an important role in the necessary increase of energy efficiency in industry. Next to the expansion of regenerative energies, it establishes a further pillar at closing the energy supply gap resulting from the energy transition. This paper presents the current energy situation in Germany and its impact on the German industry. Furthermore this paper presents a methodology which can be used by organizations to systematically implement energy management system. Eventually the paper provides a model that illustrates the realization of a PDCA cycle which is necessary for energy management in the organization.

With increasing the sustainability awareness, the goods that ends up with generating hazardous waste in dumps and landfills, are more discussed environmentally, socially, and economically. Printed Circuit Boards (PCBs), which form the basis of the high quality electronics product, are complicated to be produced due to the diversity of materials and components, and technologically waste of hazardous disposal due to the difficulty of a concrete recycling process. Thus, a sustainable life cycle of printed circuit boards requires a definite highlight of the material selection legislation, environmental burdens of the manufacturing process, and disposing and recycling process. This article presents an overview on sustainability issues with Lean paradigm perspective in PCB assembly and resource consumption showing their structure and materials, legislation issues on material and production, and the alternative solutions for the recent green innovations and production of PCBs.
