India: A team at SRM Institute of Science and Technology has patented a new concrete paving block produced using fibres from waste printed circuit board (WPCB). The refuse-derived material will replace some sand and clay in the concrete mix. SRM Institute of Science and Technology said that India generates 2Mt/yr of electronic waste (e-waste), and additionally imports this type of waste from other countries. Besides being non-biodegradable, WPCB is contaminated with colouring chemicals.

The developers said "The steadily rising volume of electronic waste poses a serious hazard to human health and the environment."
