Burning waste causes explosion

A cesspool filled with excrement has exploded in central China, injuring 15 people and knocking down a building, according to the Xinhua news agency. The blast was apparently sparked by a local man burning waste close to the cesspool, igniting methane gas which was emanating from the pit. The incident in Zhangjiajie in the central province of Hunan, caused a residential building to collapse and three of the injured were taken to hospital.

More efficient plastic sorting investigated

A new study has proposed a more efficient method for sorting plastic electronics waste containing harmful chemicals. The method combines Raman spectroscopy and X-ray spectroscopy that together can quickly and accurately detect levels of flame retardants in plastics used by the electronics industry.  According to the European Restriction of Hazardous Substances and WEEE directives, recyclable plastic products containing more than 0.1% bromine-containing flame retardants by weight have to be separated from other wastes intended for recycling.
