Mining has always been associated with risk, and as the search for metals and minerals expands, companies are operating in increasingly dangerous and remote locations. These higher hazard levels coincide with a shortage of experienced and well-trained human resources specialists, and greater focus on an employer’s duty of care. This responsibility can be divided into a moral obligation to protect employees and a legal obligation to protect the company.

The EU aims to meet 20% of its energy needs from renewable sources by 2020. Organic photovoltaics — solar cells made from plastics — could be one promising avenue. They take the form of a flexible, light film that can be easily attached to other materials and adapted to different colours and designs. This has led to potential commercial applications in the construction industry, where plastic cells could be used as a thin film on roofs, windows and facades. Moreover, they could feature in foldable chargers for mobile phones and other gadgets on car roofs, or in clothes.
