Chinese officials have destroyed 1.04 tonnes of narcotics worth more than 57.5 million US dollar in the country's east Zhejiang province.<br/><br/>The narcotics, seized in various operations in the past four years, consisted of 102 kilogrammes of heroin, 665 kilogrammes of methamphetamine, 129 kilogrammes of ketamine and 146 kilogrammes of other drugs.<br/><br/>Considering that traditional outdoor burning can emit a large amount of pollutants, police in Zhejiang decided to destroy the narcotics in furnaces at a temperature of about 850 degrees Celsius, official of the local anti-drug team said.<br/><br/>
